Firmware Engineer (KitCheck)

• KitCheck’s hardware fleet spans multiple RFID reader models, each with device-specific firmware written in different languages and frameworks. We’re looking for an engineer to take ownership of maintaining, upgrading, troubleshooting, and supporting that firmware in the field
• You’ll be a full member of our ~10-person KitCheck engineering team, working especially closely with our three-person hardware and RFID software team — a tight-knit group where firmware sits at the center
• This role is roughly 75% software, 25% hardware
• You’ll spend the most hands-on time in Python and Go — the two languages our stack leans on most heavily — though prior experience in either isn’t required
• Own firmware across our full fleet of RFID reader models — maintenance, upgrades, and troubleshooting — with each device line running its own language and framework
• Produce and maintain the support documentation and materials our Support team needs to handle day-to-day, live-device support in the field
• Take ownership of the codebase: create, review, and contribute to pull requests across a wide variety of languages and frameworks
• Contribute to and grow expertise in our RFID device-control platform, including performance-sensitive scanning code
• Our codebase spans several languages depending on the device line, including Python, JavaScript, Java, Go, TypeScript, and Ruby
