  • Role & seniority

    • Development Test Engineer (industry experience: 4+ years)

    • Focus: system-level validation for a non-invasive, ultrasound-based brain interfacing device

  • Stack/tools

    • Test systems across mechanical, electrical, acoustic, fabrication, and software

    • Hardware-in-the-loop (HIL) / instrumentation-heavy testing

    • Custom instrumentation and experimental setups (tools not specified)

  • Top 3 responsibilities

    1. Design/build test systems to evaluate performance, safety, reliability (mixed-domain)

    2. Translate risk into experiments: define system-level test priorities before clinical use

    3. Run tests, analyze results, iterate: feed learnings back into device/system design; maintain/expand a test library

  • Must-have skills

    • Experience with HIL and/or instrumentation-heavy tests (acoustic/mechanical/electrical/mixed-domain)

    • Engineering degree (or equivalent hands-on experience)

    • Systems-level thinking of the full device

    • Ability to design fast, high-signal experiments for learning/risk reduction

    • Build custom test setups from scratch when standard options don’t exist

    • Autonomous execution with strong interdisciplinary collaboration

    • Integrity and sound professional judgment

  • Nice-to-haves

    • Not explicitly stated; likely stronger depth across acoustics + electrical + hardware instrumentation and experience with **validation/characteriz

Full Description

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
