ABOUT THE ROLE

Join Hinge Health’s Hardware Engineering team to build the firmware behind next-generation, highly integrated medical devices. Your work will help bring products from concept through production and support technology designed to reduce pain and improve the lives of our members.

As a senior engineer, you’ll own a substantial firmware scope end to end, make technical decisions across prototyping, design, testing, and production, and work closely with electrical, mechanical, manufacturing, product, and design partners. You’ll help shape system architecture, strengthen the team’s engineering practices, and contribute to a small, capable group where ideas and ownership matter.

The ideal candidate is excited about solving real problems with hardware – your work will have a direct impact on reducing pain and improving the lives of our millions of members. In joining our HW group within the broader R&D organization, you will be part of a highly capable, motivated, small team where your contributions and ideas truly matter.

WHAT YOU’LL ACCOMPLISH

IN YOUR FIRST 3 MONTHS

•Learn the product architecture, firmware codebase, development workflows, and quality documentation practices

•Partner with engineering and product peers to understand system requirements, design trade-offs, and integration needs

•Take ownership of a defined firmware feature or subsystem and establish an implementation and test plan

IN YOUR FIRST 6 MONTHS

•Design, implement, and test firmware for your scope, building maintainable and testable embedded software

•Integrate firmware with electrical, mechanical, and manufacturing systems; investigate issues across hardware and software boundaries

•Improve embedded build and test automation and support clear documentation for quality and regulatory needs

IN YOUR FIRST YEAR

•Lead a complex firmware scope or project from concept through development, integration, and production readiness

WHO YOU ARE

•You take ownership of complex technical work and can move between system-level decisions and implementation details

•You work collaboratively across disciplines, communicate trade-offs clearly, and welcome feedback in design and code reviews

•You approach quality methodically, balancing development speed with robust testing and clear documentation

•You enjoy mentoring other engineers and helping a small team deliver dependable products

BASIC QUALIFICATIONS

•5+ years of professional firmware or embedded software experience writing code for consumer electronics, medical devices, or other highly integrated embedded hardware

•Strong experience with C in embedded systems, RTOS-based system architecture (such as Zephyr or FreeRTOS), low-level drivers, and hardware communication protocols such as I2C, SPI, or UART

•Experience owning firmware for a project or subsystem from design through production, including technical planning, Python-based testing or automation, version control and embedded debugging workflows

PREFERRED QUALIFICATIONS

•Experience developing medical devices or working in another highly regulated industry, such as aerospace or automotive

•Experience using AI tools to develop firmware, including copilot or agentic workflows

•Experience with Nordic nRF5x SoCs and the Nordic Connect SDK
