About the Role

We are seeking a Senior AI Engineer to build the agentic layer of our Physical AI platform. You will design, build, and ship the agents behind our engineering copilot, systems that take a real engineering problem, explore data, build and evaluate models, and return actionable results. This is a hands-on engineering role focused on turning research into reliable production systems.

Responsibilities

  • Design and build agents that run the auto-research loop on customer engineering problems: data exploration, feature and model iteration, evaluation and reporting.
  • Define tool interfaces and MCP servers that expose platform capabilities to agents in a safe and predictable way.
  • Own context and memory design for long-running agent tasks, including retrieval over engineering data, documentation and past experiments.
  • Select and integrate models, balancing quality, latency and cost.
  • Build evaluation harnesses and benchmarks that measure agent performance on real engineering use cases.
  • Instrument agents with tracing and observability and use that data to improve them.
  • Design guardrails, sandboxed code execution, permission models and human-in-the-loop checkpoints for agent safety.
  • Take agents from prototype to production: testing, CI/CD, deployment, monitoring and on-call ownership.
  • Contribute to ML work alongside ML Engineers – model training, evaluation and Physical AI library development.
  • Translate the vocabulary and workflows of physical engineering domains into agent behaviour.
  • Cover ML engineering work when needed, and help ML Engineers adopt agentic tooling.
  • Work with Research to turn promising agentic approaches into production systems.
  • Partner with platform engineers on the agent runtime, workflow orchestration and auth.
  • Work with Frontend and Product to expose agent capabilities in the product.
  • Mentor engineers, and interview and onboard new team members.

Requirements

  • 5+ years of professional software engineering experience.
  • 2+ years building production systems on top of LLMs.
  • Shipped at least one agentic system to production with real users.
  • Strong production Python.
  • Hands-on experience with LLM APIs and agent frameworks.
  • Experience designing tools and APIs for agents, including MCP or equivalent tool-calling protocols.
  • Experience building evaluation for LLM or agent systems.
  • Solid ML fundamentals: ability to train and evaluate models with scikit-learn or PyTorch, understanding validation, overfitting and uncertainty.
  • Experience with retrieval and context engineering for agents.
  • Strong software engineering practices: code review, automated testing, CI/CD, observability, Docker and Kubernetes.
  • Experience with at least one major cloud provider (AWS preferred).
  • Security-minded: sandboxing, authentication/authorisation, prompt injection and data isolation in multi-tenant systems.
  • Clear technical communication with both engineers and non-ML stakeholders.
  • Experience with auto-research, data science agents or agents that write and run experiments.
  • Experience with tabular, time-series, sensor, test or simulation data.
  • Previous experience as a backend or platform engineer before moving into AI engineering.
  • Familiarity with experiment tracking tools and notebook environments.
  • Experience serving open-source models on GPU infrastructure.
  • Experience with workflow orchestration for long-running agent tasks.
  • Experience with fine-tuning or reinforcement learning to improve agent behaviour.
  • Must be a U.S. person (U.S. citizen or national, U.S. lawful permanent resident, refugee, or asylee) or eligible to access export controlled information without authorization, or eligible and likely to obtain required authorization.
