Job summary

Neuralink seeks engineers to own the robot’s Hardware In the Loop test system, exercising production software and firmware on real hardware and automating verification for unattended operation.

You will define pass/fail criteria, integrate software-in-the-loop and hardware tests into a single CI pipeline, reproduce failures, and help deliver scalable, reliable surgical robots at scale. Evidence of exceptional abilities and drive to succeed is valued at all levels.

Qualifications

• Strong Rust skills; Python for test tooling and analysis.
• Experience with HIL, test rigs, or system-level verification.
• Experience debugging async and concurrent systems and timing failures.
• Experience building automated test pipelines; Bazel is a plus.
• Familiarity with using AI agents to accelerate repetitive tasks while maintaining quality.
• Obsessive focus on repeatability, edge cases, and traceability.

Responsibilities

• Build and maintain robot HIL — real hardware running production software and firmware.
• Write automated HIL tests for integration, timing, faults, and bring-up.
• Define pass/fail, coverage, and acceptance criteria.
• Wire software-in-the-loop tests, HIL tests, and hardware acceptance into one CI pipeline with logs, traces, and reproducible results.
• Own release-gating tests and reproduce failures to close coverage gaps.

Job description

We are creating devices that enable a bi-directional interface with the brain. These devices allow us to restore movement to the paralyzed, restore sight to the blind, and revolutionize how humans interact with their digital world.

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 robot’s Hardware In the Loop (HIL) test system. Exercise the production surgical robot, controllers and firmware against controlled inputs, reproduce faults, and automate verification. Your HIL will enable unattended test & verification to run day and night. Your work will help deliver reliable surgical robots at scale, bringing Neuralink to more people.

What you’ll do

• Build and maintain robot HIL — real hardware running production software and firmware.
• Write automated HIL tests for integration, timing, faults, and bring-up.
• Define pass/fail, coverage, and acceptance criteria.
• Wire software-in-the-loop tests, HIL tests, and hardware acceptance into one CI pipeline with logs, traces, and reproducible results.
• Own release-gating tests. When a failure escapes sim or HIL, you reproduce it and close the coverage gap.

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. Comfortable close to drivers, firmware, and buses.
• Experience with HIL, test rigs, or system-level verification on robots, vehicles, or similar hardware.
• Experience debugging async and concurrent systems, RPC, telemetry, and timing failures across software and firmware.
• Experience building automated test pipelines. Bazel experience is a plus.
• Effective at using AI agents to accelerate work while maintaining quality.
• Obsession with repeatability, edge cases, and traceability.

Expected Compensation:The anticipated base salary for this position is expected to be within the following range. Your actual base pay will be determined by your job-related skills, experience, and relevant education or training. We also believe in aligning our employees’ success with the company's long-term growth. As such, in addition to base salary, Neuralink offers equity compensation (in the form of Restricted Stock Units (RSU)) for all full-time employees.

Base Salary Range:: $151,000 USD - $281,000 USD
