Descrizione del lavoro

Nominal is seeking a Staff Engineer to lead the design and build of the agent harness and MCP platform for its UK team in London. You will shape how Nominal's agents operate, architect the single platform used by internal and external agents, and set technical direction for a cross-disciplinary team.

You will own core agent capabilities, improve context management, and drive reliability and performance of AI-driven hardware intelligence tooling in production environments.

Competenze

• 8+ years building production systems, including real experience shipping LLM or agent systems to users.
• Strong distributed-systems and backend fundamentals; you’ve owned systems where reliability mattered.
• Opinions about agent architecture (tool design, context management, autonomy, failure handling).
• A track record of setting technical direction across a team and raising the bar for engineers.

Mansioni

• Design and build the agent harness: orchestration, planning, tool calling, memory, and background agents.
• Own the shared tool layer that our agents and external agents (via MCP) both use.
• Build how agents assemble context: retrieval across data sources and large sensor data sets.
• Make model choice a decision, not a dependency: routing, cost, latency, and fallbacks across frontier models.
• Partner with evals to measure quality and with platform teams to grow the context layer.
• Set the architecture others build on, and mentor engineers.
