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. This is a hybrid role based in Austin, TX.

You can expect to

• 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.

What We Are Looking For

• Comfortable working in unfamiliar programming languages and ramping into new stacks quickly - you'll be supporting firmware across several from day one.
• Able to make progress toward a goal even when the path forward is abstract or not fully defined.
• Genuinely interested in close, ongoing collaboration with product and domain experts - this is a highly collaborative role, not a solo one.
• Strong communication habits: proactive updates, regular check-ins, and comfortable flagging blockers early rather than going quiet.
• Early-career engineers with strong fundamentals who are excited by broad language and hardware exposure will thrive here.

Nice to have

• Experience building or supporting on-premise / on-device software.
• Exposure to IoT device build/dev as a hobbyist or tinkerer.
• Networking fundamentals (TCP/IP, common protocols).
• General Linux systems knowledge.
• Familiarity with how web applications communicate (REST APIs, client-server request/response patterns).
• Familiarity with our day-to-day toolset: macOS working environment, Linux development, Git/GitHub, Jira, Slack, and Docker containers

Our environment

Our codebase spans several languages depending on the device line, including Python, JavaScript, Java, Go, TypeScript, and Ruby.

What you'll get from us

• Opportunities to solve problems of scale, debt and security to redefine what’s possible in medication intelligence
• Room to be creative and choose your own path
• Trust in your sense of ownership
• Dedicated budget for training and career development
• Coworkers who you'll learn from, who will push you and who are looking to learn from you
