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 Electronics Architect, you will own the architecture, and oversee the design and development of the electronic systems at the core of CoMind's neurological and physiological monitoring devices. As a recognised Subject Matter Expert in precision analogue and mixed-signal design, you'll build the front-end acquisition systems, signal conditioning chains, and high-speed digital interfaces that capture and process the physiological signals clinicians depend on. This is a senior technical role with full ownership — from early architecture decisions through to manufacturing release — working alongside the electronic, FPGA, 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 in the office, plus a flexible work-from-home day. This role can be based in either the London (Kings Cross) or Bristol office. RESPONSIBILITIES: - Establish the electronics system architecture and requirements from system-level requirements (product, clinical, regulatory) including signal chain topology, noise budgets, power architecture, and interface strategies - Ensure that design input requirements are complete and unambiguous to enable the electronics design team to proceed with detailed design - Lead the end-to-end architecture, design, development, and verification of electronic systems across the full product lifecycle - Work across cross-functional boundaries negotiating constraints and resolving conflicts with adjacent disciplines (software, mechanical, optics, clinical) to integrate electronic subsystems into the wider product - Select appropriate components and platform architectures and drive design trade-offs across performance, noise, power, cost, and reliability - Design of precision analogue front-end circuits for low-noise signal acquisition, including transimpedance amplifiers, instrumentation amplifiers, and ADC interface design - Design mixed-signal subsystems bridging analogue acquisition and high-speed digital back-ends, including AFE integration and layout-sensitive design practices - Design high-speed digital systems including signal integrity analysis, controlled-impedance PCB design, and high-speed interface implementation - Define and drive electronics verification and validation strategy, including simulation, benchtop characterisation and EMC / safety compliance testing - Lead design reviews, architecture discussions, and technical risk assessments - Ensure electronic 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 - Lead reliability / FIT analysis on electronic PCBAs and safety critical components - 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. SKILLS & EXPERIENCE: - 10+ years of professional electronics design experience - Experience with safety-critical design practices, including single-fault failure analysis and f
