JOB-2045

An early-stage company building AI agents that operate complex desktop CAD, simulation and PLM software for mechanical engineers is looking for a senior engineer to work on the core agent layer, reporting to the CTO.

What you’ll own

  • Own major pieces of the agent: tool calling, long-running state, error recovery, context handling and model routing
  • Profile and tune latency and cost per workflow, and help keep each task within a token budget
  • Write robust production code that drives real desktop applications on locked-down enterprise machines
  • Build evaluation infrastructure and benchmarks based on real user stories, working with researchers and domain experts
  • Review code, make sound design calls and work with integration, product and customer teams during pilots

Profile

  • 3 to 10 years building and maintaining production software (5+ preferred)
  • Exceptionally strong computer science and software engineering fundamentals
  • Depth in Python plus at least one other language
  • Curiosity about agentic systems; prior LLM agent work is a plus but not required
  • Bonus: desktop automation or programmatic control of applications, enterprise deployment experience, or time at a hyper-growth startup

On-site in San Francisco, five days a week. Visa sponsorship available.
