Job Description
Firmware Engineer (Embedded Systems | Wearables)
Full-Time | On-site | Austin, TX
$145K – $175K + Equity
About the Opportunity
They are building a genuinely category-defining wearable-style consumer health device, a connected, battery-powered product designed to make continuous health tracking effortless and actionable.
Their long-term vision is ambitious: transforming how people monitor and understand their health, with the potential to enable early detection of serious conditions through passive, everyday use.
Backed by experienced founders who have previously scaled high-growth technology companies, they’ve recently closed significant funding and are now entering a critical phase of product development and scale.
This is a rare opportunity to join extremely early and take full ownership of a core part of the product.
The Role
They are looking for a Firmware Engineer to take ownership of the entire embedded firmware stack for a connected wearables / consumer hardware device.
This is a hands-on, high-impact role where they will be responsible for everything from early hardware bring-up through to production firmware, OTA updates, and fleet reliability.
The position is fully on-site in Austin to enable rapid iteration, real-world debugging, and close collaboration with hardware and backend teams.
What You’ll Be Doing
- Own the firmware stack end-to-end - from hardware bring-up through to production deployment and OTA updates
- Drive aggressive power optimisation toward a ~60-day battery life target
- Debug and stabilise noisy, real-world sensors to ensure consistent device performance
- Build and maintain robust OTA systems where reliability is critical at scale
- Collaborate closely with hardware and backend teams to ensure seamless device-cloud interaction
- Take full responsibility for firmware quality, performance, and long-term maintainability

What They’re Looking For
Must-Have Experience
- Strong embedded C development experience
- Proven track record shipping production firmware on connected, battery-powered devices
- Deep experience with power optimisation
- Experience building and maintaining OTA update systems in production environments
Highly Valued
- Wearables or consumer health device experience (e.g. fitness trackers, smart devices)
- Experience debugging and stabilising real-world sensor data
- Hardware bring-up experience (from early prototypes to production)
- Experience working with MCUs, RTOS, and BLE-based systems

Tech Environment
- Embedded C
- MCU-based systems
- RTOS
- BLE connectivity
- Real-time, resource-constrained environments
Why This Role Stands Out
- Full ownership of the firmware stack - not just a small piece of a large system
- Deep technical challenges across power optimisation, sensor reliability, and OTA at scale
- Greenfield opportunity to define how firmware is built and scaled
- Immediate impact - stepping into a role with clear ownership and responsibility
- Small, high-calibre team where contributions directly shape the product

Compensation & Benefits
- Base salary: $145K – $175K (flexibility for exceptional candidates)
- Equity: 0.1% – 0.3%
- Strong funding and runway
- Visa sponsorship available (H1B transfers supported only)
Location & Working Style
- On-site, 5 days per week in Austin, TX
- Fast-paced, highly collaborative environment
- Ideal for engineers who enjoy hands-on debugging and rapid iteration
The Bigger Picture
They are building something entirely new in the wearables and consumer health space - a product with the potential to become a daily health signal for millions of people.
For engineers motivated by ownership, technical depth, and meaningful real-world impact, this is a rare early-stage opportunity with significant upside.
