Who We're Looking For

We are seeking a Senior Firmware Engineer who owns their work completely — someone who can walk into a hardware bring-up, assess the state of the firmware, and immediately know what needs to be done and in what order. You don't need a spec to get started, and you don't need a manager to tell you when something's off.

The person we’re looking for is happy, relaxed and easy to get along with. They’re flexible on anything except conceits that will lower their usually outstanding work quality. They work “smart”, by carefully managing their workflow and staggering features that have dependencies intelligently — they prefer deep work but are OK coming up to the surface now and then for top level / strategic conversations.

We think people with backgrounds or interests in design, art, music, food or fashion tend to have a well rounded sense of design & quality — so a variety of hobbies or side projects is a big nice to have!

Role Details & Responsibilities

In this role, you'll work across a range of embedded initiatives, from connectivity and OTA infrastructure to display integration and sensor pipelines, finding pragmatic, cost-effective solutions to hard real-time problems. You'll collaborate directly with hardware engineers, product teams, and clients, and you'll be expected to hold your own in all three rooms.

Responsibilities will include

• Owning firmware architecture decisions across one or more active product platforms
• Bringing up new hardware revisions and integrating peripheral drivers with minimal ramp time
• Monitoring deployed firmware in the field, triaging issues, and shipping fixes with urgency and discipline
• Designing and implementing wireless connectivity flows - pairing, OTA, reconnect logic, fleet health
• Reprocessing and validating firmware behavior across hardware variants and edge cases
• Integrating new sensors, actuators, and communication modules into existing firmware architectures
• Participating in code reviews and holding a high bar - style, correctness, and long-term maintainability
• Keeping close track of project scope, timeline, and technical risk - and surfacing problems before they become crises
• Communicating directly with clients to align deliverables with constraints when scope and reality diverge

Who You Are

They work “smart”, by carefully managing their workflow and staggering features that have dependencies intelligently — they prefer deep work but are OK coming up to the surface now and then for top level / strategic conversations.

The person should be open to diverse interests; we believe people with backgrounds or interests in design, art, music, food or fashion tend to have a well rounded sense of design & quality — so a variety of hobbies or side projects is a big nice to have!

The Ideal Candidate & Shipping History

We’d love to see someone with a track record of shipping real products. You know the difference between firmware that works in the lab and firmware that survives in the field — and you build for the latter from day one. You’re comfortable making architectural decisions under ambiguity, and you document those decisions so the team can follow.

You will find pragmatic, cost-effective solutions to hard real-time problems.
