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.
