Electronics EngineerHours: 35 hours per weekLocation: Central London (at least 2 days per week, including Wednesdays), with remote working for the remainder (subject to change depending on business needs).About the RoleWe are seeking an Electronics Engineer to join a dynamic health technology team developing innovative, non-invasive sensor systems for advanced medical applications. The work focuses on creating scalable and accessible solutions that improve early detection, reduce healthcare costs, and enhance patient outcomes.As a key member of the hardware team, you will take ownership of hands-on hardware development, with an emphasis on analogue and mixed-signal design. Your responsibilities will range from troubleshooting and refining circuits to running experiments that inform algorithm development. You will also support preparation for regulatory testing, maintain lab hardware, and contribute to long-term technology roadmaps.Technical HighlightsLow-noise analogue front-end design for capacitive sensing applicationsPrecision small signal routing and conditioning (filters, amplifiers, multiplexers)High-speed ADC/DAC integration and mixed-signal circuit optimisationSchematic capture, PCB layout, BOM management (Altium Designer)Circuit modelling and simulation (SPICE, MATLAB, or similar tools)Designing to meet IEC 60601 and related medical device standards, within an ISO 13485 compliant QMSKey ResponsibilitiesLead hardware development activities from ideation and prototyping to optimisation and maintenancePlan and conduct benchtop experiments in collaboration with algorithms and clinical teamsManage and maintain prototype hardware for studies and trials, ensuring reliability and identifying design improvementsSupport verification, validation, and compliance testing with regulatory partnersContribute to design reviews, documentation, and alignment with quality management processesProvide technical input into long-term technology roadmaps to shape future biosensing devicesRequirementsEssentialMaster’s degree in Electrical/Electronic Engineering or related discipline, OR 3+ years’ experience in a highly regulated industryStrong knowledge of analogue circuit design, including low-noise front ends, filters, amplifiers, and signal conditioningProven experience with schematic capture and PCB layout using industry-standard design softwareProficiency with test and measurement equipment (oscilloscopes, VNAs, spectrum analysers, waveform generators, etc.)Excellent documentation and reporting skills (Office 365, Atlassian suite)Experience with design control processes: requirements capture, verification, traceability, and documentationExperience working within a quality management systemDesirableFPGA experience and associated design considerationsPython skills for data processing and test automationBackground in medical device developmentExperience with biosensors or low-amplitude analogue acquisition systems (impedance, ECG/EEG, oximetry, etc.)Basic knowledge of mechanical considerations in electronics design (thermal management, enclosures, connectors, etc.)Familiarity with FEM simulations of electromagneticsEmbedded code development and GitHub/Bitbucket for source controlStrong commitment to producing high-quality work in a regulated environmentBenefitsShare optionsPrivate medical and dental cover5% employer pension contributionLife and health insuranceLunch allowance when working onsiteFlexible working model (2 days/week onsite, remote at company discretion)25 days annual leaveBonus scheme (subject to milestones and policies)How We WorkThe team is a close-knit group of scientists and engineers who value solving complex problems and seeing them through to impact. Everyone has the opportunity to shape both the technology and the culture, with a strong emphasis on accountability, collaboration, and transparent communication. Growth comes through meaningful work, shared learning, and open knowledge exchange.If you want to contribute to technology that makes a real difference while working alongside passionate peers, this could be the role for you.
