About Us
The Ammortal Chamber integrates five science-backed modalities into one immersive session. Our clients include wellness clinics and spas, sports teams and athletic departments, hotels, and individuals who bring the Chamber into their homes.
We are a small team with a startup culture. Hardware and software engineers, health professionals, and operators work side by side. Since shipping our first product we have grown steadily, and the software that drives the Chamber is now at the center of what comes next.
This role offers hands-on experience across the whole product, close mentorship from a senior engineer, and the chance to see your work running in the field.
What is this role and why does it exist?
This role centers on Linux systems software for the Chamber: building application-level software that runs on embedded Linux and interfaces with hardware over common serial and bus protocols (the software layer that sits above the firmware and drives the product). You'll occasionally reach up the stack into frontend work as well, giving you end-to-end understanding of the system.
You'll need a solid programming foundation, comfort in Linux, and real curiosity about how software talks to hardware. You'll work directly with the hiring manager, who will guide your ramp-up and grow your responsibilities as you build confidence. This is a role where you can go deep in embedded Linux and systems software while learning the full shape of a shipping hardware product.
Responsibilities
- Develop features and fixes for Chamber application software on embedded Linux, with guidance from senior engineers
- Learn and contribute to the software that communicates with hardware over serial and bus protocols
- Write clean, tested code and participate in code reviews
- Take part in quality assurance to help keep Chamber software reliable
- Help investigate and resolve customer issues, escalating when needed
- Assist with maintenance of early-gen Chamber software
- Contribute to frontend work as needed
- Collaborate with hardware, operations, and customer experience teammates
Skills to Excel
- Curiosity: Wants to understand how things work under the hood, from the operating system down to the wire
- Continuous Learning: Picks up new languages, tools, and patterns quickly and enjoys doing it
- Attention to Detail: Organized and methodical in development and testing
- Coachability: Takes feedback well, asks good questions, and applies what you learn
- Independent + Collaborative: Balances initiative with knowing when to ask for help
- Systems Thinking: Interested in how different layers of the stack fit together
- Customer Focus: Cares about how technical work affects the people using the product
- Comfortable Multitasking: Can manage a few priorities at once and switch between them
- Team Collaboration: Works well in a small, cross-disciplinary team
