• Proficient in Python for creating tools for firmware testing and task automation

• Experience developing in a team environment using version control (Git) and with embedded development tools and workflows (setting up build systems, J-Link, debugging)

• Familiarity with electrical engineering design – You can read datasheets and schematics, or deep dive with an EE to do a pin/peripheral allocation for an MCU

• Competency with standard lab equipment such as oscilloscopes, logic analyzers, multimeters, and power supplies

• Experience working in medical device development or, alternatively, within another highly regulated industry (aerospace, automotive, etc.)

• Experience developing firmware with the help of AI, both as a copilot and in agentic mode

• Experience developing with an RTOS, especially Zephyr

• Experience with Nordic nRF5x SoCs and the Nordic Connect SDK

• Experience with Bluetooth LE

• Experience with bootloaders, firmware update, and managing memory maps

• Familiarity with Dev Ops for embedded – CI pipelines (Git Hub Actions, Git Lab CI) and automated testing with hardware-in-the-loop (HIL) setups

At Hinge Health, we're using technology to scale and automate the delivery of healthcare – starting with musculoskeletal (MSK) conditions, which affect over 1.7 billion people worldwide. With an AI-powered human-centered care model, Hinge Health leverages cutting-edge technology to improve outcomes, experiences and costs to help people move beyond their pain.

The platform addresses a broad spectrum of MSK care – from acute injury, to chronic pain, to post-surgical rehabilitation – through personalized, evidence-based care. As the preferred partner to 50+ health plans, PBMs and other ecosystem partners, Hinge Health is available to over 20 million people across more than 2,550 employers. The company is headquartered in San Francisco with additional offices in Montreal and Bangalore.

• Inclusive healthcare and benefits: On top of comprehensive medical, dental, and vision coverage, we offer employees and their family members help with gender-affirming care, tools for family and fertility planning, and travel reimbursements if healthcare isn't available where you live.
