Agent Systems Engineer
Engineer job in Fremont, CA
Senior Agent Systems Engineer
We're representing a frontier AI research group building autonomous systems that can reason, plan, and operate complex real-world engineering workflows. This is a core engineering role shaping how intelligent agents interact with tools, data, and long-horizon tasks.
⭐ The Opportunity
Join a small, high-performing team designing the orchestration, planning, and execution layer that enables LLM-driven agents to reliably complete multi-step engineering processes.
What You'll Do
Build agent planning and orchestration systems that coordinate tool calls, workflows, and long-horizon tasks
Design schemas, action interfaces, and deterministic execution flows
Implement robust error-handling, rollback, retry, and reproducibility strategies
Own the tooling logic that connects agents to real engineering stacks
Partner with ML researchers, infra teams, and domain experts to deliver production-grade agent systems
What You Bring
Experience building agent systems, orchestrators, tool-use frameworks, or structured LLM pipelines
Strong systems-engineering fundamentals - deterministic thinking, reliability, and failure-mode awareness
Comfort designing workflows that integrate with complex real-world tools
Ability to work in a fast, experimental environment where robustness matters
Why This Role Excites People
Build agent systems that control real physical-world workflows, not just simulations
Huge scope for technical ownership and creative problem-solving
Mission-driven environment focused on breakthrough autonomy
Competitive salary + strong equity in a fast-scaling AI organization
Interested?
If you're passionate about building reliable, intelligent agent systems at the cutting edge of AI and autonomy, we'd love to speak.
