Fluxergy is a rapidly growing in vitro diagnostics company innovating on the cutting-edge of laboratory testing. We’re developing the first and only multi-modal point-of-care platform that enables molecular, clinical chemistry, immunoassay, and hematology testing on the same system.
Our platform spans many markets including the clinical, veterinary, and food safety industries. We are seeking self-motivated problem solvers who are excited to help decentralize traditional laboratory infrastructure.
At the core of our company’s identity is a strong foundation in engineering. We take great pride in our commitment to critical thinking and pragmatic problem-solving through a modular and systemic perspective. We hold the conviction that transparent communication, coupled with the flexibility to adjust to evolving scenarios and the willingness to venture beyond familiar territories, is crucial to both our success and yours.

We’re looking for an engineer who’s ready to level up—not just in skill, but in impact. This role is built for someone who enjoys solving complex, not-fully-defined problems and wants to play an active part in shaping the product. You’ll be working on a system that’s evolving in real time, where your ideas and contributions directly influence what gets built and how it performs.
You thrive in collaborative environments where ownership is shared, ideas are challenged, and progress happens as a team. You’re naturally curious, comfortable with ambiguity, and motivated by building something meaningful—not just maintaining it. If you enjoy turning complexity into clarity and want to grow alongside a team tackling hard problems together, you’ll feel right at home here.

Identify, analyze, and resolve bugs or system-level challenges as they arise
Design and improve intra-device communication interfaces (UART, SPI, I2C)
Explore and implement new methodologies to enhance existing features, backed by data-driven analysis
Participate in code reviews across teams and contribute to engineering best practices
Create and maintain clear, thorough technical documentation
Build internal tools to support development, testing, and team efficiency
Be an awesome team member (see team culture bullets above).
What You'll Need to Have
5+ years developing and releasing firmware for embedded or IoT devices
Familiarity with embedded Linux, Yocto, and at least one RTOS

What We Do
Fluxergy was founded 10 years ago with a vision to democratize the world of laboratory testing, by making testing more accessible and affordable. Fluxergy’s platform technology enables us to understand our world and our health in ways that were never possible before. Fluxergy is developing a platform with multi-modal detection technologies which bring the variety of tests found in the central lab to the palm of your hand – This includes molecular testing like PCR, Immunochemistry and chemistry testing, and microscopy testing such as cytometry. Fluxergy’s platform vision is the detection of genes, proteins, small molecules, and cells with the same analyzer. The automated, sample-to-answer workflows can be customized for specific sample and testing methods.
