Job Details

Senior LLM Research Scientist | Advanced AI Systems | San Francisco (Onsite)

Join a team building AI with real physical capability—systems that can experiment, engineer, and manufacture in the real world. Backed by deep technical foundations and large-scale programs, they're pushing the frontier of advanced intelligence. The work is hands-on and first-principles, with full ownership of end-to-end systems and the chance to create capabilities that don't yet exist.

Why join

• Lead research in planning, reasoning, and tool use for autonomous engineering systems

• Shape prompting frameworks, structured tool calling, model alignment, and preference optimization

• Work on verifier-guided RL, long-horizon behavior, and MoE routing in a fast-moving research environment

• Collaborate closely with systems, data, simulation, and tooling teams operating real engineering workflows

• Competitive compensation up to $300k base, plus meaningful equity

What they value

• Strong background in LLM research, agent systems, or structured tool-use models

• Experience with SFT, RLHF, DPO, or verifier-driven RL

• Expertise in long-horizon reasoning, decomposition, and structured policy design

• Comfort working across ML research, engineering systems, and real-world toolchains
