United Football League (UFL) is hiring a Principal Engineer

About the Role

The United Football League (UFL) is hiring a Principal Engineer to lead the development of next-generation embedded systems for life sciences platforms. You will bridge the gap between complex biological assays and high-performance hardware, ensuring diagnostic and research instruments operate with precision and reliability. Your work will define the architecture that enables breakthroughs in genomics, proteomics, and molecular diagnostics.

What You'll Do

  • Design and implement scalable, robust firmware architectures for complex mechatronic systems, including thermal control, fluidics management, and high-speed data acquisition.
  • Collaborate with Product and Science teams to translate biological requirements into technical specifications.
  • Lead firmware development from initial proof-of-concept through hardware abstraction layers (HAL) to production-ready RTOS or bare-metal environments.
  • Work closely with Electrical, Mechanical, and Software Engineering to ensure seamless system integration and hardware-software co-design.
  • Ensure all firmware development meets stringent medical device standards (e.g., IEC 62304, ISO 13485) and cybersecurity protocols.
  • Act as a technical mentor to senior and staff engineers, fostering a culture of rigorous code reviews, unit testing, and continuous integration.

What We're Looking For

  • BS/MS in Electrical Engineering, Computer Science, or a related field.
  • 10+ years in embedded systems, with 5+ years in a Principal or Lead role.
  • Deep experience with FreeRTOS, Zephyr, ThreadX, or Embedded Linux.
  • Mastery of ARM Cortex-M/A, FPGAs, and communication protocols (I2C, SPI, CAN, USB, Ethernet).
  • Proven track record in Life Sciences, Medical Devices, or IVD (In-Vitro Diagnostics).

Nice to Have

  • Experience with Control Systems.

Technical Stack

  • RTOS/OS: FreeRTOS, Zephyr, ThreadX, Embedded Linux
  • Hardware: ARM Cortex-M/A, FPGAs
  • Protocols: I2C, SPI, CAN, USB, Ethernet

Team & Environment

You will report to the Director of Engineering.
