About Us
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.

About the Role
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.
Team culture:
- Positive
- Proactive
- Accountable
- Team oriented
- Continuous learner
- Great communicator
- Build strong working relationships
- Contribute to a productive team culture
What You Will Do
- Develop, test, and release firmware for embedded and IoT-based systems

- Bring up, verify, and debug new hardware systems, including the Fluxergy Analyzer
- Collaborate with cross-functional teams to support system integration and troubleshoot issues
- 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
- Proficiency in C (C98) and C++ (C++11)
- Experience with bring-up, verification, and troubleshooting of embedded systems
- Ability to design and improve communication protocols like UART, SPI, and I2C
- Willingness to experiment, iterate, and apply quantitative analysis to improve systems
- Ability to work effectively across teams and clearly document and share work
- Comfort navigating ambiguity and tackling unforeseen challenges in a system built from the ground up
- Background in medical devices or similar industries is highly valued
- Have worked on an FDA regulated project
- Are familiar with safety critical design processes and controls
- Ability to read schematics
