From exabyte-scale knowledge indexes to codegen-first agent runtimes, the building blocks behind Perplexity's applications are some of the most battle-tested AI systems in the industry. We believe these same building blocks can and should power the aspirations of builders everywhere. It's one thing to solve planet-scale retrieval, long-horizon orchestration, and other foundational AI challenges within a single product ecosystem. The true measure of success is to turn those solutions into elegant APIs that delight developers and agents alike. Our API Platform delivers frontier intelligence to thousands of customers: startups, trillion-dollar enterprises, U.S. and allied governments, and everyone in between. We've achieved incredible scale, yet we're just getting started. Join us to build tools for curious minds. ABOUT THIS ROLE Perplexity is seeking strong engineers with a passion for delivering frontier intelligence and infrastructure to developers. Our company builds technology that reshapes how people search, reason, and interact with the world around them. Week after week, we observe increasing demand for programmatic interfaces to that technology. The API Platform engineering team is charged with designing, implementing, and scaling these interfaces. As a member of our team, you'll work on an eclectic portfolio spanning distributed systems, performance optimization, agent orchestration, and frontier topics that often change with each passing month. Throughout this work, you'll prioritize great developer and agent experience alike. You'll also define technical strategy for how we scale to meet compounding growth exponentials (number of customers, agents per customer, compute/retrieval per agent, etc.). KEY RESPONSIBILITIES - Design, build, and operate mission-critical APIs that provide our customers the building blocks for frontier intelligence. - Ensure low latency and high throughput through aggressive performance optimization (including on upstream systems). - Continually reimagine the customer needs of tomorrow (and the architectures to serve those needs), while faithfully serving the customer workloads of today. - Harden system security and reliability across heterogeneous compute environments. - Collaborate across teams to incorporate novel frontier capabilities into the API Platform and improve existing capabilities for API customer needs. - Uphold engineering excellence through design reviews, code quality, and internal documentation.

ABOUT THE ROLE The Connector Platform team builds the data layer that lets Perplexity's agents reach into the world's software. This team owns the systems that turn hundreds of heterogeneous integrations (native, MCP, CLI, first-party, and third-party APIs) into one unified, reliable, well-typed surface that agents can call with confidence. The connector platform is the core layer that forms the knowledge layer for Computer: it is how the agent discovers what tools exist, understands what each one means, decides which to call, and grounds its reasoning in real, permissioned, up-to-date enterprise data. We maintain a knowledge layer above connectors that pushes and pulls context into them, rather than letting each connector hoard org knowledge on its own, making Computer the source of truth for institutional knowledge. Models are commoditizing; grounded, actionable, permissioned access to a customer's real systems is not. When this layer is fast, accurate, and semantically rich, every agent built on top of it gets smarter; when it is weak, no amount of model quality compensates. KEY RESPONSIBILITIES - Own the design and implementation of the connector runtime, the system that registers, hosts, and executes built-in connectors, hosted MCP servers, and CLI-backed tools behind a single agent-facing interface. - Build and extend the semantic layer: tool and entity schemas, capability metadata, relationship modeling, and the mechanisms for capturing and applying organization- and account-specific corrections and knowledge. - Design the tool-discovery and tool-selection surfaces that agents use to find the right connector and call it correctly, optimizing for both model accuracy and context efficiency. - Make agent loops robust: structured results, partial-failure and retry semantics, idempotency, pagination, rate-limit handling, and observability into every tool call an agent makes. - Define authentication, authorization, and credential-isolation patterns for connectors (OAuth flows, BYOK, per-org credential boundaries), partnering with Security and Backend Platform on defense-in-depth. - Build the connector onboarding path (schemas, fixtures, and evaluation suites) so new connectors ship with measurable quality rather than hope, and drive the eval metrics that tell us a connector actually works inside agent loops. - Set the technical bar for connector reliability and operability: SLAs, observability, error-rate monitoring, and incident response for an always-on, high-fan-out integration surface. - Partner with product and AI teams to define clear connector interfaces and integration patterns so new agent capabilities can reliably build on the shared platform. QUALIFICATIONS - Experience designing and building backend systems that run in production (typically 4+ years for mid-level, more for senior and staff). - Strong system design skills, with a track record of building efficient, reliable, and scalable architectures, ideally including API integration, gateway, or platform-style systems with many heterogeneous downstreams. - Strong proficiency in at least one backend language such as Python, Go, or Rust, and the ability to work effectively in a multi-language environment. - Hands-on experience with modern infrastructure (for example AWS, Kubernetes, and related cloud technologies). - Depth in at least one of: OAuth and authorization protocols, API/connector or MCP-server development, schema and semantic modeling, or building tooling and evaluation for LLM-based agents. - Comfort working in security-sensitive areas (auth, authorization, credential isolation) and making pragmatic trade-offs between safety, simplicity, and velocity. - Collaborative mindset and eagerness to solve hard, ambiguous problems alongside other experienced engineers. If you’re excited about this role, we encourage you to apply even if your experience doesn’t match every qualification listed above.

ABOUT THE TEAM The User Operations team at Perplexity AI is the frontline of our user experience. We ensure that our AI-powered search and answer engine delivers real value to every user—from individual consumers to teams and organizations. Our team operates across 3-4 active support channels—email, in-app messaging, Slack, and community—and collaborates closely with Product, Engineering, Billing, and Growth to turn user feedback into product improvements. We’re a lean, fast-moving group at a startup that ships constantly, so everyone on the team wears multiple hats and contributes well beyond just resolving tickets. ABOUT THE ROLE Perplexity launches new features and products at a rapid pace—and this role sits at the center of that. We need a User Operations Generalist who combines excellent customer support instincts with real technical depth. You’ll handle high volumes of user inquiries across channels while also digging into product issues, using customer feedback to uncover problems, and providing solutions that improve the experience for everyone. This isn’t just ticket work. As new features and products ship, you’re the person who hears about it first from users—what’s working, what’s confusing, and what’s broken. You’ll use those interactions to surface insights that shape how launches land, identify issues before they scale, and provide clear solutions back to users. You’ll also build automations and improve workflows that make the team faster and smarter, so we can keep up with the pace of the product without sacrificing quality. You should be comfortable operating across multiple support channels and have experience standing up or optimizing multi-channel support operations—not just working in them, but thinking critically about how they’re structured, routed, and scaled. This role requires someone who can navigate ambiguity and fill in the gaps where processes don’t yet exist. You won’t always have a playbook—and that’s the point. We need someone who can define the path forward, not just follow one. You’re a strong, independent operator who doesn’t need to be told what to do next: - You see the gap—whether it’s a missing Help Center article, a broken workflow, or a pattern in user tickets—and you move to fix it - You’re self-motivated and take initiative, but you also know when to ask questions - You communicate effectively with the team—keeping people informed, surfacing blockers early, and making sure nothing falls through the cracks - We won’t hold your hand through this role, and we wouldn’t want to—because you’re the kind of person who thrives when given ownership and trust RESPONSIBILITIES - Handle a high volume of user inquiries across channels (email, chat, Slack, community) with speed, accuracy, and empathy for both consumer and business users. - Deliver excellent customer support—clear, thoughtful, and human—even under pressure and at scale - Triage and prioritize effectively to keep response and resolution times on target - Use customer feedback and support interactions as a primary source for uncovering product issues, UX confusion, and feature gaps—especially as new products and features launch - Investigate and troubleshoot product issues: reproduce problems, isolate root causes, provide users with solutions or workarounds, and document findings for Engineering - Guide users through technical troubleshooting: AI search, LLM behavior, account configuration - File well-documented bugs in Linear with enough context for Engineering to act immediately - Leverage AI tooling and automation (Intercom, scripts) to streamline operations, reduce repetitive work, and scale support quality - Write and maintain Help Center articles, internal SOPs, escalation playbooks, and troubleshooting guides - Communicate cross-functionally—surface user insights to Product and Engineering, escalate issues, close the loop, and keep teammates informed - Track support KPIs and propose data-driven process improvements REQUIREMENTS - 3+ years in customer support, user operations, or technical support—ideally at a SaaS or tech company - Proven ability to manage high ticket volumes while maintaining quality and empathy - Excellent customer-facing communication: clear, professional, and adaptable to different audiences - Technical aptitude: comfortable working through product issues, navigating technical questions independently, and learning new tools and systems quickly - Hands-on experience with AI tools and automation platforms (Intercom workflows, scripting) to improve operations - Familiarity with AI, LLMs, or search technologies - Strong internal communication—keeps their immediate team informed, writes crisp updates for immediate team and cross-functional partners (Product, Engineering, etc.), and ensures stakeholders stay in the loop on issues and progress - Self-motivated and proactive: manages own priorities, takes initiative, delivers without waiting for direction - Experience creating user-facing documentation (e.g., Help Center articles, FAQs, guides) as well as internal SOPs, templates, and playbooks - Experience with multi-channel support operations—not just working across channels, but helping stand up, optimize, or scale how support is structured and routed - Comfortable in a fast-paced, high-volume startup environment with shifting priorities NICE TO HAVE - Experience with support and operations tooling such as Intercom, Parahelp, Linear, Notion, or Stripe. - Familiarity with prompting techniques and LLM optimization - Basic web tech understanding (HTTP, REST APIs, JavaScript, HTML) - Data analysis tools (SQL, Looker, Snowflake) - Scripting or lightweight automation background (Google Apps Script, Python) - Experience at an early-stage or high-growth startup WHO YOU ARE You’re the kind of person who: - Sees a gap and fills it before anyone asks - Thrives in high-volume environments and keeps quality high even when things move fast - Thinks creatively—you don’t just follow the playbook, you look for better ways to solve problems and aren’t afraid to try something new - Treats every user interaction as a chance to learn something about the product - Gets energized by building automations that save the team hours - Communicates with clarity—whether writing a Help Center article, filing a bug, or updating the team in Slack - Takes full ownership end-to-end: you don’t just escalate, you follow through WHY PERPLEXITY? Impact at Scale – Your work directly influences millions of users and shapes the future of AI-powered search. Velocity & Ownership – Ship improvements quickly in a culture that values curiosity, speed, and quality. Cutting-Edge Tech – Operate at the forefront of applied LLMs and help define how AI transforms customer support.

ABOUT THE ROLE In 2026, we launched Computer, the defining product for the new era of agentic AI. Millions of people now use Perplexity to transform knowledge into action, through Search, Comet, and Computer. Product Engineering owns those experiences end to end, from the interface a user touches to the search and model calls behind it, on top of roughly 200M queries a day and a 200B+ URL index. This is a full stack role in the truest sense. There are no frontend or backend lanes here, and no one waits for a ticket before starting. It suits people who love to build and want the room to do it. What you have shipped and how quickly you learn tell us far more than years on a resume or where you went to school. WHAT YOU WILL DO - Own a user-facing surface end to end, from the interaction, design, and frontend through the application logic, APIs, data models, and the search or model calls behind them. - Ship to production continuously. New engineers typically have code in front of users in their first week. - Build with AI as a primary tool, not a novelty. We expect you to use agents and coding models aggressively to move faster, and to have sound judgment about when their output is wrong. - Turn ambiguous product ideas into working prototypes, then use real usage data and evals to decide what survives. - Raise the quality bar on reliability, latency, and craft for the surfaces you own. - Work directly with designers, PMs, and research engineers, without unnecessary process in between. WHAT WE LOOK FOR - 1+ years of professional software engineering experience, or a track record of strong internships where you shipped production code at scale. - Strong in at least one backend language, such as Python or Go, with real experience across services, APIs, and relational data modeling. Comfortable working in React and TypeScript on the frontend. - Real evidence of building: production work you understand in depth, shipped side projects with actual users, meaningful open-source contributions, hackathon wins, or research you turned into working software. - Comfort with ambiguity and an instinct to start building incrementally rather than wait for a spec. - Hands-on experience with AI products, with opinions about their rough edges and what that means for the product you are building. NICE TO HAVE - Experience with our stack: React or Next.js, Python, Go, PostgreSQL, Redis, Docker, AWS. You will not be expected to know all of it on day one. - Experience building on top of LLMs: AI orchestration, RAG, evals, agents, tool use. - Product taste. You can tell a good interface from a bad one and explain how to improve it. - A public track record we can read, such as GitHub, a technical blog, or a demo we can try.
