Machine Learning Engineer / ML Engineer - Roleplay...

Negotiable

Synthesia is the world’s leading AI video platform for business, used by over 90% of the Fortune 100. Founded in 2017, the company is headquartered in London, with offices and teams across Europe and the US. As AI continues to shape the way we live and work, Synthesia develops products to enhance visual communication and enterprise skill development, helping people work better and stay at the center of successful organizations. Following our recent Series E funding round, where we raised $200 million, our valuation stands at $4 billion. Our total funding exceeds $530 million from premier investors including Accel, NVentures (Nvidia's VC arm), Kleiner Perkins, GV, and Evantic Capital, alongside the founders and operators of Stripe, Datadog, Miro, and Webflow. ABOUT THE ROLE Synthesia Roleplay Sessions is a training tool that lets people practice real conversations with AI avatars. Instead of just watching training videos, learners do interactive roleplay exercises, like practicing a sales pitch or handling a customer complaint with an AI coach. The AI gives instant feedback so people know what they did well and what to improve. Managers can use a dashboard to track which employees have completed their training, see how well they performed, and measure if the training actually improved their skills. The whole platform is built around learning by doing rather than just passive video watching. For your ML engineer role, you'd be building the AI engine that makes the coaching work. That means creating the models that listen to what learners say during roleplay, score their performance, generate helpful feedback in real time, and decide how the AI avatar should respond next based on what the learner does. This is an applied ML position, not a research one. We expect you to have a good understanding of ML but on the other side to be a good product-focused software developer as you will be expected to work on different products. PLEASE BRING WITH YOU: - Ability to apply your machine learning knowledge to solve real product problems. - At least seven (7) years of experience as a software engineer, with at least 2 years at senior level. - Experience in a high-performing engineering team operating at scale, whether in a scale-up or established organisation recognised for strong engineering culture. - Strong alignment with commercial success. - Pragmatism and bias towards action. This role requires comfort with fast iteration. WHY JOIN US? We’re living the golden age of AI. The next decade will yield the next iconic companies, and we dare to say we have what it takes to become one. Here’s why, OUR CULTURE At Synthesia we’re passionate about building, not talking, planning or politicising. We strive to hire the smartest, kindest and most unrelenting people and let them do their best work without distractions. Our work principles serve as our charter for how we make decisions, give feedback and structure our work to empower everyone to go as fast as possible.

About Etched Etched is building hardware for frontier intelligence. We co-design chips, racks, software, and manufacturing to deliver best-in-class throughput and latency across both prefill and decode workloads. Our first products are heavily focused on inference. Backed by hundreds of millions from top-tier investors and staffed by leading engineers, Etched is redefining the infrastructure layer for the fastest growing industry in history. Job Summary We are using AI to build AI chips. AI agents are starting to genuinely work for verification, debug, and EDA flows — we want someone to bring that inside Etched and push past it. As an Applied AI Engineer, you will embed with our hardware teams — RTL design, verification, DFT, physical design, and silicon validation — and build the agents and tooling that multiply their output. You'll wire LLM agents into simulators, regressions, waveform and log analysis, EDA flows, and bring-up workflows, and own the evals that separate demos from tools engineers actually rely on. This is an internal, force-multiplier role: your success is measured by how much faster the chip team moves, not by lines of code you ship yourself. It is not a customer-facing role and not about inference serving — it's AI applied to how we build the chip itself. You do not need to be a chip designer or a traditional software engineer — you need to be an exceptional problem solver who has shipped real agentic systems, works comfortably across stacks and domains, and uses AI to ramp on hard new problems fast. Key responsibilities - Build, deploy, and maintain LLM-agent workflows that accelerate chip development: debug triage, testbench and coverage work, log/waveform analysis, EDA script generation, and engineering knowledge retrieval - Embed with hardware teams to find the highest-leverage pain points, then turn them into automated workflows with measurable adoption - Design rigorous evals for agent performance on real silicon-engineering tasks — not proxy metrics — and use them to drive iteration - Integrate agents with our internal infrastructure: simulation and emulation flows, CI/regression systems, lab equipment, and issue tracking, via tool-calling and MCP - Champion adoption: documentation, training, and fast feedback loops with the engineers who use what you build You may be a good fit if you have - A track record of solving hard problems across stacks and domains — you enjoy being dropped into unfamiliar territory and figuring it out - Comfort with Python and code: you can read it, modify it, debug it, and direct AI to write it well. We do not care whether you write code from scratch — we care whether you ship things that work - Fluency using AI to learn and ramp on new problems — agentic coding tools, deep research, and frontier models are how you work, not an add-on - Hands-on experience building and shipping LLM-based agents or AI tooling that real users depend on (beyond calling an API — context engineering, tool integration, orchestration, failure analysis) - An eval-driven mindset: you measure whether AI systems actually work before scaling them - High agency and comfort with ambiguity — you can find the problem, not just solve the stated one - Interest in chip development and the ability to ramp quickly on a deeply technical domain. Hardware experience is a real plus, but not required — you will be willing and able to learn quickly Strong candidates may also have experience with - Chip development in any form (the strongest plus): RTL/SystemVerilog, functional verification (UVM), DFT, physical design/STA, FPGA, emulation, or silicon bring-up and validation - EDA tool flows and Tcl scripting; reading waveforms, logs, and regressions - Fine-tuning or post-training (SFT, RLHF/DPO), RAG over proprietary technical data, or multi-agent orchestration - Deep software engineering: C++ or Rust, developer-facing internal platforms, CI/CD at scale, or infrastructure (Docker, Slurm, Ray) Representative projects - In your first 30 days, pick one hardware team's worst recurring pain, ship an agent for it, and prove adoption with usage data - Build an agent that triages overnight regression failures, clusters them by root cause, and drafts bug reports with waveform and log evidence attached - Wire Claude Code-style agents into our EDA and validation flows via MCP so engineers can drive simulations, queries, and lab equipment from natural language - Create a retrieval system over our specs, design docs, and past debug history that cuts ramp time for new engineers - Design an eval suite that measures agent performance on real verification and debug tasks, and use it to decide which workflows to automate next - Prototype AlphaEvolve-style optimization loops that propose and automatically verify improvements to test programs or flow scripts Benefits - Full medical, dental, and vision packages, with generous premium coverage - Housing subsidy of $2,500/month for those living within walking distance of the office - Daily lunch and dinner in our office - Relocation support for those moving to San Jose (Santana Row) - Unlimited compute budget subject to ROI justification How we're different Etched believes in the Bitter Lesson http://www.incompleteideas.net/IncIdeas/BitterLesson.html.

Applied AI Engineer, Kernel Performance

Negotiable

About Etched Etched is building hardware for frontier intelligence. We co-design chips, racks, software, and manufacturing to deliver best-in-class throughput and latency across both prefill and decode workloads. Our first products are heavily focused on inference. Backed by hundreds of millions from top-tier investors and staffed by leading engineers, Etched is redefining the infrastructure layer for the fastest growing industry in history. Job Summary Every model release presents a new opportunity to push the frontier on kernel engineering. Future performance breakthroughs will come from AI systems that can understand model architectures and hardware, run thousands of experiments, learn from profiler feedback, and discover the most performant implementations faster than the best engineers. You will build that system. Your mandate is to build AI systems that autonomously turn newly released model architectures into correct, production-ready implementations optimized for Etched hardware. These systems should explore broader design spaces, learn from every experiment, and reach peak performance faster than any traditional kernel-development workflows. Etched offers a uniquely tight research loop: proprietary hardware, runtime, kernels, production workloads, and dedicated in-office compute under one roof. You will teach models using proprietary performance signals, iterate on their proposals, and make every experiment improve both the performance optimization system and the hardware it runs on. Key Responsibilities - Own the system that turns new model architectures into verified, production-ready kernels and model mappings. - Build agents that understand Etched hardware, design experiments, generate implementations, profile them, diagnose bottlenecks, and iterate with our teams, to the limits of model autonomy. - Design evals covering correctness, numerical stability, latency and efficiency. - Turn profiler traces, simulation, hardware counters, and expert judgment into structured signals models can learn from. - Curate proprietary datasets and optimization memory from complete trajectories, expert demonstrations, counterexamples, and production outcomes. - Build fast, reproducible experiment infrastructure and observability so experiments remain interpretable, trustworthy, and high-throughput. - Ship model-generated improvements to production and quantify their impact on end-to-end system performance. - Partner deeply with other architecture teams to shape new abstractions and Etched’s hardware-software roadmap. - Continuously evaluate new model releases and deploy the best for each stage of the optimization loop. You may be a good fit if you have - A track record of solving hard problems across stacks and domains — you enjoy being dropped into unfamiliar territory and figuring it out - Comfort with both Python and low-level code: you can read it, modify it, debug it, and direct AI to write it well. We do not care whether you write code from scratch — we care whether you ship things that work. - Kernel experience: you've written or tuned kernels and can explain the mechanisms and performance impact of optimizations you’ve shipped - Fluency using AI to learn and ramp on new problems — agentic coding tools, deep research, and frontier models are how you work, not an add-on - Moving fluidly between research exploration, agentic experimentation, low-level debugging, and production execution. Strong candidates may also have experience with - First principles thinking on accelerator performance: memory hierarchy, data movement, parallelism, synchronization, and low-precision computation. - Hands-on experience building and shipping LLM-based agents or AI tooling that real users depend on in production environments (beyond calling an API — context engineering, tool integration, orchestration, failure analysis) - An eval-driven mindset: you measure whether AI systems work before scaling them - Fine-tuning or post-training, RAG over proprietary data, and/or multi-agent orchestration - High agency and comfort with ambiguity — you find the real problem to solve Benefits - Medical, dental, and vision packages with generous premium coverage - $500 per month credit for waiving medical benefits - Housing subsidy of $2,500 per month for those living within walking distance of the office - Relocation support for those moving to San Jose (Santana Row) - Various wellness benefits covering fitness, mental health, and more - Daily lunch and dinner in our office - Unlimited compute budget subject to ROI justification Base Compensation Range - $150,000 – $225,000 How we’re different Etched believes in the Bitter Lesson http://www.incompleteideas.net/IncIdeas/BitterLesson.html.
