Base Salary

$170k - $282k/yr

Responsibilities

  • Build agentic harnesses for autonomous driving with permissioned access to software, data, training infrastructure, and evaluation environments.
  • Develop recursive self-improvement loops using failure mining, candidate generation, evolutionary search, and targeted data generation.
  • Curate and validate reusable skills derived from verified fixes.
  • Train and fine-tune LLMs on agent development trajectories and adapt them to the software stack, tools, and codebase.
  • Develop agent-as-policy approaches that modify policy logic, curate data, adjust training recipes, and diagnose driving failures.
  • Shape onboard architecture while balancing latency, compute, determinism, and safety requirements.
  • Work with prediction, planning, simulation, and onboard teams to productionize research prototypes.

Requirements

  • Strong machine-learning background, including deep learning, reinforcement learning, or decision-making systems.
  • Hands-on experience building LLM agent systems involving tool use, multi-agent orchestration, or automated evaluation loops.
  • Experience training or fine-tuning LLMs for agentic workflows, including trajectory curation, supervised fine-tuning, or reinforcement learning from execution feedback.
  • Strong Python skills and working knowledge of C++.
  • Rigorously conduct controlled experiments and held-out evaluations, distinguishing measured results from assumptions.
  • Ability to own systems from research prototype through production.
  • Preferred: experience building agentic harnesses or self-improving loops for a product or domain.
  • Preferred: autonomous-driving or robotics experience, especially in planning, prediction, simulation, or sim-to-real transfer.
  • Preferred: familiarity with code-as-policy, program synthesis, LLM-driven optimization, or evolutionary search.
  • Preferred: publications at top machine-learning or robotics venues such as NeurIPS, ICML, ICLR, CVPR, RSS, or CoRL.
  • Preferred: BS, MS, or PhD in Computer Science, Machine Learning, Robotics, or a related field.

Benefits

  • Annual base salary range is $169,783–$282,264, with additional bonus, equity, and benefits.
  • Compensation varies by role, level, location, skills, experience, and education or training.
