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:

The Software team at CoMind spans the full stack of a regulated medical device company — from embedded and real-time systems through application software, ML inference, GUI, DevOps, and test engineering. It is a team that builds across every layer, working to medical device software standards and shipping software that has to perform reliably in clinical environments.

As a Staff Software Engineer, you will be a technical authority within the Software team, owning complex technical problems in embedded and real-time C++ development. You will work across hardware abstraction, real-time data acquisition, and system integration, bringing the depth of experience needed to architect and deliver software that performs reliably in a regulated, safety-critical context.

At CoMind, all team members work at least 4 days per week from our new Kings Cross office, plus a flexible work-from-home day.

Responsibilities:

• Design, implement, and maintain high-performance embedded and real-time software components in C++, including hardware abstraction layers, device drivers, and data acquisition pipelines.

• Define and drive technical strategy, proactively identifying and mitigating cross-team dependencies and technical debt while setting the long-term vision for embedded architecture.

• Act as a technical bridge, synthesising and communicating complex architectural decisions to non-technical stakeholders (including Product, Clinical, and Regulatory teams) to ensure alignment on project goals.

• Mentor and grow engineers, fostering a culture of technical excellence, code quality, and professional development within the broader software team.

• Ensure software quality through code review, unit and integration testing, and strict adherence to CoMind’s software development lifecycle under IEC 62304.

• Collaborate with electronics and FPGA teams on hardware-software interfaces, supporting hardware bring-up, system integration, and complex debug.

• Contribute to risk management and design documentation activities, including software hazard analysis and traceability in line with ISO 14971 and CoMind’s QMS.

• Participate in design reviews, sprint planning, and cross-functional technical forums, contributing to a high-performance engineering culture.

• 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 experience in software engineering, with a strong focus on systems-level software architecture

• Deep expertise in modern C++ (C++17 or later), including memory management, concurrency, real-time constraints, and performance optimisation

• Hands-on experience developing software for embedded Linux environments, including device driver development and hardware abstraction

• Experience in a regulated industry (medical devices, aerospace, automotive, or similar) including familiarity with IEC 62304 or equivalent software development standards

• Strong understanding of hardware-software integration, including FPGA or microcontroller interfaces, communication buses (SPI, I2C, UART, PCIe), and real-time operating systems

• Demonstrated ability to write clean, well-tested, and maintainable code in a safety-critical context

Nice to Have

• Experience with high-speed data acquisition systems or real-time signal processing pipelines

• Familiarity with optical or biomedical hardware integration

• Background in or exposure to data science or ML pipelines and the software interfaces that feed them

• Experience with CI/CD tooling, automated testing frameworks, and static analysis tools in an embedded context

• Knowledge of IEC 60601-1-4 or other medical device software standards

• Familiarity with architecture and engineering of cloud-based IoT systems

• Experience with health-tech data residency

Benefits:

• 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
