Development Test Engineer — Hardware-in-Loop Systems

Healy World; San Francisco (CA); On-site; USD 90,000 - 150,000; Full time

Job summary

Nudge is building non-invasive brain interfacing technology. We seek a development test engineer to design and build test systems that evaluate device performance, safety, and reliability across mechanical, electrical, acoustic, fabrication, and software components.

You will identify critical system‑level tests, translate risk into high‑signal experiments, and execute tests while feeding learnings back into design.

Qualifications

• Experience building hardware-in-the-loop or instrumentation-heavy tests (acoustic, mechanical, electrical, or mixed-domain).
• A degree in an engineering discipline or equivalent hands-on experience.
• Strong systems-level thinking of the entire device rather than isolated components.
• Comfort designing scrappy, fast experiments focused on learning and risk reduction.
• Proven ability to work autonomously while collaborating closely with interdisciplinary engineering teams.
• A track record of building custom test setups from scratch when no standard test exists.
• High integrity and strong professional judgement.

Responsibilities

• Design and build test systems to evaluate device performance, safety, and reliability.
• Identify what matters most to test at a system level and translate risk into high-signal experiments before clinical use.
• Execute tests, analyze results, and feed clear learnings back into device and system design.
• Own and grow a library of validation and characterization tests as the system evolves.
