Staff Software Engineer

Job description

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
