Autonomy Safety Engineer - Lean Proofs & Checks

Bedrock Robotics Inc; San Francisco (CA); On-site; USD 36,000 - 60,000; Part time

Job summary

Bedrock Robotics is seeking a Safety Engineering intern to advance formal methods at the intersection of statistics, safety cases, and field robotics. You will formalize safety claims, verify Lean checkers, and evaluate proofs using fleet data in a hands-on internship.

Join a team integrating formal verification with autonomy, systems, and safety to strengthen safety arguments and improve evidence-driven decision making aboard live fleet operations.

Qualifications

• Hands-on experience with Lean and mathlib experience, particularly real analysis or probability.
• Working knowledge of probability and statistics (distributions, confidence intervals, tail bounds).
• Familiarity with knowledge graphs or structured document analysis
• Ability to translate informal claims into precise specifications and identify their assumptions
• Experience evaluating LLM-generated code or proofs.
• Background in autonomous vehicles, heavy equipment, or other safety-critical robotics.

Responsibilities

• Become fluent in Bedrock's safety case and trace safety claims through the hazards, requirements, mitigations, and evidence that support them
• Build an end-to-end demonstration for one claim: define the property and assumptions, implement a checker in Lean, prove its correctness against the specification, and run it on fleet data
• Develop checks for assumptions that can be monitored in fleet data, and document those that require other evidence
• Build audit tooling for LLM-assisted proving: record proof dependencies, document toolchain trust assumptions, and reject proof placeholders or unapproved axioms in automated builds
• Work with Safety, Systems, and Autonomy teams to review formal specifications and turn findings into safety case improvements
• Document the results, limitations, and recommendations for adoption in our review process
