Senior FPGA Engineer

Senior FPGA Engineer (Full-Time)

Location: Onsite — Louisville, Colorado

Type: Full-time, on-site

Reports To: Director of Research & Development

ABOUT FIELDLINE MEDICAL

FieldLine Medical is a Colorado-based medical device company pioneering optically pumped magnetometer (OPM) technology for functional brain imaging. Our HEDscan system is redefining magnetoencephalography (MEG), making whole-head brain measurement more accessible than ever. We are a small, fast-moving team of scientists and engineers building technology with real clinical impact.

THE ROLE

We are looking for a Senior FPGA Engineer to improve upon the existing HEDscan FPGA architecture, help design the next-generation HEDscan system, design, verify, and implement new accessory cards for our platform. You will own FPGA subsystems end to end — from architecture through verification — working at the hardware/software boundary to keep our systems fast, stable, and reliable.

WHAT YOU’LL DO

• Architect, implement, and verify FPGA designs for our HEDscan system
• Design and implement high-speed serial transceiver links between HEDscan chassis
• Design and incorporate DDR4 memory on the System on Module
• Improve existing real-time control and DSP data paths (filtering, decimation, feedback loops) that keep the sensor array stable
• Drive timing closure, resource budgeting, and design-for-test across Arria 10 devices
• Build simulation and verification environments
• Partner with embedded software on the hardware/software boundary, register maps, DMA, and SoC integration
• Contribute to design documentation and verification evidence within our ISO 13485 design control process
• Participate in on-site testing and measurements using the HEDscan system

WHAT WE’RE LOOKING FOR

Required

• B.S. in Electrical Engineering, Computer Engineering, or a closely related field; M.S. preferred
• 7 years of professional FPGA design experience, with a track record of owning a subsystem end to end
• Experience with SystemVerilog
• Hands-on experience designing and debugging high-speed serial transceivers (SerDes, multi-gigabit links, clock/data recovery, equalization, jitter and eye-diagram work)
• Practical DDR4 experience: controller integration, calibration, timing closure, and real-world throughput debugging
• Strong lab and debug skills
• Self-directed and independent with a willingness to learn on the go
• Ability to work on-site in Louisville, CO

Nice to Have

• Experience with Intel/Altera FPGAs, particularly Arria 10
• Experience with Efinix FPGAs (Trion T20)
• DSP and control-systems background — digital filters, feedback loops, closed-loop sensor control
• C and System-on-Chip development, including Arria 10 HPS or similar hard-processor integration
• Experience in a regulated medical device environment (ISO 13485, IEC 62304, design controls, V&V documentation)
• Familiarity with Git-based workflows

COMPENSATION & BENEFITS

Base salary range: $130,000 – $165,000 per year
