About this Agent Evaluation and Self-Improvement Engineer role at NVIDIA
Autonomous agents now do real work across NVIDIA, and every piece underneath them keeps changing: models, harnesses, tools, skills, and plugins. Evaluation is how a team knows whether a change made an agent better or quietly made it worse. We're looking for a principal engineer to set evaluation strategy at every layer, from individual skills and MCP servers to whole agents and products, and to design how agents use those results to improve themselves.
Agents can already rewrite the skills and plugins they run on, then test whether the change helped. Making that loop trustworthy is the hard part. What does it take for an agent to get better on its own, and prove the improvement is real? We're building a system that answers that question for every agent at NVIDIA. Come build it with us!
What you'll be doing:
- Build evaluation that works the same across harnesses, with automated checks on every change that catch regressions before users do.
- Mine production traces for failures, new usage patterns, missing skills and tools, cost and latency hot spots, and successful runs. Turn them into eval cases and improvement signals.
- Evaluate the eval datasets themselves: coverage of real usage, duplicate cases, and how closely they match production.
- Build the self-improvement loop for evolving harnesses: agents propose changes to their own skills, plugins, and harness configuration, and sandboxed evals test each one. Only measurable gains ship, with human sign-off and limits agents can't change.
- Create realistic enterprise environments: sandboxed replicas of issue trackers, code repositories, chat, and internal APIs, filled with synthetic or anonymized data, where agents safely run long, end-to-end tasks.
- Measure multi-agent swarms as a team: how agents split work, whether handoffs succeed, and whether permissions hold at every hop. Record how long each task takes and how many tokens it uses.
- Keep evals honest: calibrate model and agent judges against human labels. Catch agents that cheat, such as working backward from expected answers or reaching data and tools they shouldn't access. We work closely with product, platform, and hardware teams throughout NVIDIA, and we help shape open evaluation standards and benchmarks across the industry.
What we need to see:
- BS or MS in Computer Science, Engineering, or related field (or equivalent experience)
- 12+ years building large-scale systems, including evaluation systems for ML or agents and the data pipelines that feed them
- Hands-on experience building and evaluating agents on an open or closed agent harness
- Solid grounding in experiment design: statistical significance, variance across repeated runs, and A/B testing
- Experience setting technical direction across teams as a senior individual contributor
- Proficiency in Python, Go, Rust, or similar
Ways to stand out from the crowd:
- Built self-improving or self-evolving agent systems that get better from their own eval results
- Shipped an agent benchmark, eval framework, or simulated test environment adopted by other teams
- Detected reward hacking or eval gaming, or built oversight for systems that modify themselves
- Built domain evaluations, such as for chip design or hardware verification
