Job description
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 a hands-on Electrical Engineer who thrives on ownership, collaboration, and solving complex technical problems. In this role, you’ll contribute to the development of electronic systems for diagnostic and life sciences products, working across the full hardware development lifecycle—from design and prototyping through testing, integration, and production.

You’ll have the autonomy to drive your work forward while working closely with a multidisciplinary engineering team. We value engineers who communicate clearly, ask thoughtful questions, take initiative, and know when to lean on their teammates. You’ll have the opportunity to work on meaningful technical challenges while seeing your designs move from concept to production in a regulated environment.

What You Will Do
  • Design and review electrical schematics, PCB layouts, wiring diagrams, BOMs, and system architectures.
  • Collaborate with mechanical, firmware, software, and manufacturing teams to develop and integrate reliable electronic systems.
  • Own electrical design activities from design and prototyping through testing, troubleshooting, verification, and documentation.
  • Support hardware bring-up, design verification, system integration, and prototype builds.
  • Design and implement PCBA test fixtures and test procedures for manufacturing and functional testing.
  • Troubleshoot complex hardware and system-level issues using oscilloscopes, logic analyzers, spectrum analyzers, power supplies, and other laboratory equipment.
  • Create and maintain technical documentation, including design specifications, verification protocols, test procedures, and engineering reports.
  • Support PCB development from prototype through production, including Design for Manufacturability (DFM) and manufacturing support.
  • Ensure designs comply with FDA requirements and applicable medical device industry standards.
  • Communicate technical decisions, risks, tradeoffs, and project timelines clearly across cross-functional teams.
  • Participate in design reviews, technical discussions, and continuous improvement initiatives.
  • What You'll Need to Have
  • Bachelor’s degree in Electrical Engineering or a related engineering discipline.
  • 5+ years of hands-on experience designing, developing, testing, and troubleshooting analog and digital hardware.
  • Strong understanding of analog and digital circuit design, power electronics, signal integrity, and embedded systems.
  • Experience with schematic capture and PCB design using Altium Designer or similar ECAD software.
  • Experience with embedded hardware and microcontrollers, including interfaces such as I2C, SPI, and UART.
  • Strong hardware debugging and troubleshooting skills using laboratory test equipment.
  • Experience designing and building PCBA test fixtures for manufacturing, functional testing, or troubleshooting.
  • Familiarity with PCB manufacturing, DFM, and supporting hardware from prototype builds through production.
  • Strong communication and collaboration skills with the ability to work effectively across disciplines.
  • A demonstrated ability to work autonomously, take ownership, manage priorities, and drive projects forward.
  • Experience in medical devices, diagnostic instruments, life sciences, or another regulated industry is preferred.
  • Experience with STM32 microcontrollers and development toolsets is a plus.
