At CoMind, we are developing a non-invasive neuromonitoring technology that will result in a new era of clinical brain monitoring. In joining us, you will be helping to create cutting-edge technologies that will improve how we diagnose and treat brain disorders, ultimately improving and saving the lives of patients across the world.
The Role:As the FPGA Architect, you will own the design, architecture, and development of the FPGA systems at the core of our neuromonitoring device. As a recognised Subject Matter Expert in FPGA design principles you'll build the real-time data acquisition, digital signal processing, and high-speed communication systems that turn optical signals into the physiological data clinicians depend on.
This is a senior technical role with full ownership — from early architecture decisions through to manufacturing release — working alongside electronics, software, mechanical, and optics engineers in a regulated medical device development environment.
You will be a key member of the Hardware Engineering team responsible for the hardware for CoMind's medical devices — from precision analogue circuits and high-speed digital systems, to FPGAs for data acquisition, control and signal processing, and PCB design through to mechanical enclosures, optical assemblies and consumable sensors.
At CoMind, all team members work at least 4 days per week from our new Kings Cross offices, plus a flexible work-from-home day.
Responsibilities:Lead the end-to-end architecture, design, development, and verification of FPGA systems across the full product lifecycle
Define FPGA system architecture from product and clinical requirements, including clocking, reset, memory, and interface strategies
Select appropriate Xilinx FPGA/SoC platforms (e.g., Zynq, UltraScale+) and drive design trade-offs across performance, power, cost, and reliability
Build real-time data acquisition pipelines, DSP subsystems, and high-speed communication interfaces in Verilog/VHDL
Lead RTL design, microarchitecture definition, timing closure, and resource optimisation in Vivado
Define and drive verification and validation strategy, including simulation, hardware-in-the-loop testing, and timing/power analysis
Use Xilinx debugging tools (ILA, VIO, etc.) to support hardware bring-up and lab validation
Collaborate cross-functionally with electronics, software, mechanical, and optics teams to integrate FPGA subsystems into the wider product
Lead design reviews, architecture discussions, and technical risk assessments
Ensure FPGA solutions are scalable, testable, and cost-effective for volume manufacturing
Maintain design documentation and traceability in line with medical device regulatory requirements (FMEA, hazard analysis)
Mentor engineers as the team grows
AI is fundamental to our culture — it's not just a tool, but a core part of how we work, collaborate, and innovate. We expect all team members to embrace AI in their daily work and continuously find new ways to use it effectively.
10+ years of FPGA development on products that made it to market
Experience with safety-critical design practices, including single-fault failure analysis and fail-safe techniques
Strong proficiency in Verilog or VHDL for RTL design
Hands-on experience with Xilinx Vivado and Siemens’ QuestaSim (synthesis, implementation, simulation, and debug)
Experience with high-speed interfaces such as JESD204B, PCIe, DDR, or high-speed serial transceivers up to 10Gbps lane rates
Proven DSP implementation on FPGAs — filtering, spectral analysis, real-time processing
Full FPGA lifecycle experience: architecture, design, verification, integration, and production support
Experience bringing hardware from prototype to production
Experience in medical device development or regulated industries (e.g. IEC 62304, ISO 13485 or other applicable standards)
Familiarity with optoelectronic systems or instrumentation
Experience with Xilinx UltraScale+ or similar high-performance platforms
Exposure to hardware control loops and real-time closed-loop systems
Experience mentoring or technically leading other FPGA engineers
Company equity plan so all employees share in the success of the company
Salary-sacrifice pension scheme
Private medical, dental and vision insurance (medical history disregarded)
Group life assurance at 4x annual income
Comprehensive mental health support, including unlimited access to 1:1 sessions with trained professionals
Unlimited holiday allowance (+ bank holidays) and one week of remote working per quarter
Lunch voucher (£10) every day for JustEat and free dinner on those days where you need to work later
Twice weekly deliveries of fresh fruit and an extensive selection of snacks and drinks
YuLife subscription, allowing you to turn your daily steps and meditation into discounts at a range of stores
