Development Test Engineer

About Nudge At Nudge, our mission is to develop the best technology for interfacing with the brain to improve people's lives. We're starting with an approach that we believe can help the most people the fastest, and also allow us to learn as much about the brain as possible: developing a non-invasive, ultrasound-based device that can stimulate and image the brain at high resolution and depth. This is a vertically integrated effort building cutting-edge hardware, software, and research capabilities to create products that can benefit millions — and eventually billions — of people. To succeed, we need to assemble world-class teams across everything we do. We hire people who are exceptional at their craft, believe hard things are worth doing, and execute relentlessly — people who expect the highest levels of both rigor and integrity from each other. About the role As a development test engineer at Nudge, you will: - Design and build test systems to evaluate device performance, safety, and reliability with mechanical, electrical, acoustic, fabrication, and software components - 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 About you We are looking for engineers with at least 4 years of industry experience. Regardless of career level, you should have: - Experience building and running hardware-in-the-loop or instrumentation-heavy tests (acoustic, mechanical, electrical, or mixed-domain) - A degree in an engineering discipline (mechanical, electrical, mechatronics, engineering physics, or similar) 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 rather than polish - 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
