Job summary

Nominal is building the Hardware Intelligence Platform to give engineers visibility into physical systems and accelerate real-world deployment. As a ML engineer, you will identify failure modes of agents on real hardware, design evals and data pipelines, and build graders to verify improvements.

You’ll prototype across research bets, run experiments, and help ship high‑impact improvements to our agents and tools used by aerospace, energy, and robotics teams.

Qualifications

• 3+ years in ML engineering or research.
• Hands-on experience improving an LLM or agent system through evals, data, post-training, or harness changes.
• Strong engineering: you write the pipeline, the training script, and the grader yourself.
• Experimental judgment: you design experiments that don't fool you.

Responsibilities

• Find where our agents fail on real hardware work, from customer traces and from tasks you design with hardware experts.
• Turn those failures into evals, environments, and training data grounded in real test results.
• Build graders and verifiers that check agent work against measured data, and find where they break.
• Prototype across our research bets: hardware context for agents, computer use in engineering tools, linking simulation to physical tests.

Job description

About Nominal

Engineers today are building some of the most ambitious machines humanity has ever seen. They should have AI that’s purpose-built for them.

Nominal is building the Hardware Intelligence Platform that gives engineers increased visibility into complex physical systems, helps them make better decisions, and ultimately gets their products into the real world faster. It brings together the systems, data, intelligence, and applications hardware engineering requires to meet the AI moment. Hardware engineering teams use Nominal to simulate, test, manufacture, and operate the physical systems that keep the world moving, from spacecraft and autonomous vehicles to next-generation energy systems and robotics.

Our customers span aerospace, defense, manufacturing, transportation, energy, and robotics. They include Anduril, Shield AI, Wisk Aero, Pratt Miller Motorsports, Antares, and Shinkei Systems, amongst others, alongside programs within the U.S. Air Force and Navy. Our team draws from SpaceX, Palantir, Anduril, Applied Intuition, Tesla, and other leading companies, united by a common mission: giving hardware engineers the tools to build the future with speed, safety, and confidence. We're a fast-moving team that owns problems end-to-end, works across disciplines, and thrives at the intersection of hardware and software.

Some of the world’s leading technology investors, including Sequoia, Lightspeed, Founders Fund, General Catalyst, Lux Capital, and Insight Partners, are backing Nominal’s ambition to change how machines are built and operated. We’re looking for engineers who want to take on hard problems and help make a new generation of world-changing hardware possible.

About Hardware Intelligence

We're going after the biggest opportunities to accelerate how the world engineers: agents that are expert at engineering physical systems, not just competent at calling tools. Nobody has a recipe for that yet. Hardware gives us an edge most domains lack: real test results to check agent work against. You'll set the research agenda, decide where to turn that ground truth into better context, better tools, or models of our own, run the first experiments yourself, and grow the researchers who run the next ones.

What you'll do

• Find where our agents fail on real hardware work, from customer traces and from tasks you design with hardware experts.
• Turn those failures into evals, environments, and training data grounded in real test results.
• Build graders and verifiers that check agent work against measured data, and find where they break.
• Fix what you find: change a prompt, tool, or context, fine-tune, run RL, or distill an open-weight model.
• Prototype across our research bets: hardware context for agents, computer use in engineering tools, linking simulation to physical tests, coordinating collections of agents, and intelligence at the edge.
• Build the research infrastructure the loop runs on: eval harnesses, dataset and trace pipelines, and training and experiment tooling that make the next experiment faster to run and easy to reproduce.
• Separate real gains from noise, ship what wins into the agents customers use, and write up what you learn.

What you’ll bring

• 3+ years in ML engineering or research. Less is fine if your recent work was doing exactly this at a frontier lab or an AI-native company.
• Hands-on experience improving an LLM or agent system through evals, data, post-training, or harness changes, and proving it worked.
• Strong engineering: you write the pipeline, the training script, and the grader yourself.
• Experimental judgment: you design experiments that don't fool you, and you know when a difference is real.
• Comfort picking the next experiment when nobody can tell you what will work.
• You build with modern AI coding agents (Claude Code, Cursor, Codex) every day, and stay curious and open to better ways of working. The tools keep changing, and so do we.

Nice to have

• You’ve done post-training (SFT, RL from feedback or verifiable rewards, distillation) on real tasks.
• You’ve built RL environments, synthetic-data pipelines, or benchmarks that other people use.
• You’ve worked on computer-use agents, multi-agent systems, simulation, or edge deployment.
• You’ve worked with time-series, sensor, or scientific data, or with models built over it.
• You’ve been an engineer in hardware, test, controls, or robotics, or worked closely with those teams.
