Software Engineer - Simulation

Location: Austin, Texas, United States; South San Francisco, California, United States

Department: Software

The Role

Neuralink’s next generation surgical robot will perform brain surgery at scale, installing hundreds of tiny threads into the brain to enable brain computer communication.

You will own the end to end surgical robot simulation. Perform surgery and run tests on the simulated robot. Reproduce faults, and automate verification. Your simulation will enable test & verification to run on every commit.

What you’ll do

• Build the full robot sim: dynamics, sensors, actuators, and product-stack interfaces.
• Test the real robot software and firmware against simulated hardware.
• Write automated sim tests: scenarios, regressions, fault injection, and coverage.
• Make runs deterministic, measurable, and cheap enough to run in CI.
• Reproduce hardware failures in sim to accelerate our test timelines.
• The success of the project is on you. You talk to users, get feedback, and iterate fast.

Note: The team is hiring engineers at all levels, both junior and senior. What matters most is evidence of exceptional abilities and a drive to succeed.

What we’re looking for

• Strong Rust skills; Python for test tooling and analysis. Bazel experience is a plus.
• Real robotics / physics sim experience (MuJoCo, Isaac Sim, Gazebo, or equivalent).
• Experience with async and concurrent systems, hardware interfaces, RPC, and telemetry.
• Experience building automated integration tests and debugging failures across software and firmware. 
• Effective at using AI agents to accelerate work while maintaining quality.
