Senior ECU & Electronics Hardware EngineerAdvanced EV, Battery & Powertrain SystemsOverviewWe are recruiting a Senior ECU & Electronics Hardware Engineer to join a established engineering organisation developing next-generation electric powertrain and battery technologies. This role sits at the intersection of advanced EV systems and motorsport-pace engineering, delivering real hardware into real testing and deployment environments.This is not a software-only or late-stage production role. You will design, build, test and own ECU-level hardware used within battery management systems, powertrain control and supervisory electronics. The work is hands-on, technically demanding and safety-critical, supported by long-term investment and organisational scale.The RoleYou will take end-to-end ownership of ECU and electronic control hardware, from early concept and architecture through schematic, PCB design, bring-up, validation and production release. Alongside hardware delivery, you will play a key role in developing and supporting Hardware-in-the-Loop (HIL) systems used to validate EV battery and powertrain architectures.The environment is fast-paced and prototype-led, but with the structure, funding and stability of a major global engineering organisation. Engineers in this team work closely with firmware, software, systems and test teams to deliver robust, high-performance solutions.Key ResponsibilitiesLead ECU and electronic hardware design from concept through to productionDesign mixed-signal, safety-critical control and interface boardsPerform circuit design, simulation, schematic capture and PCB layout oversightOwn board bring-up, debugging and fault diagnosis using lab equipmentDevelop, support and debug ECU-connected HIL rigsSupport battery, powertrain and control hardware during lab, rig and test activitiesApply high-voltage-aware design principles, including isolation, creepage and clearanceSelect components with consideration for EMC, thermal and reliability requirementsDefine and execute hardware test strategies, including EVT, DVT and PVTWork closely with embedded firmware and software engineers to deliver integrated systemsMentor junior engineers and contribute to continuous improvement of team processesTechnical RequirementsECU & Electronics HardwareProven experience designing ECU-level electronics hardwareMixed-signal, safety-critical board design experienceEnd-to-end ownership from schematic through PCB and validationStrong hands-on lab capability; comfortable debugging your own designsEV, Battery & Powertrain SystemsExperience with BMS hardware, battery control units or EV powertrain electronicsUnderstanding of HV battery systems, charging and power electronicsExposure to high-voltage PCB design practicesTools & Practical SkillsPCB design experience using Altium, Cadence, Zuken or MentorConfident use of oscilloscopes, logic analysers and bench equipmentPractical soldering, rework and prototype modification skillsEmbedded & ECU InterfacesExperience working with microcontrollers or processorsCommunications: CAN, SPI, ISO-SPI, IC, UARTCAN bus design, termination and EMI mitigationSafety, Quality & StandardsUnderstanding of EMC and EMI mitigationGrounding strategies and transient protectionFamiliarity with functional safety principlesExperience applying DFMEA and hardware verification methodsExposure to automotive or motorsport-grade design standardsIdeal BackgroundAutomotive, EV, motorsport or advanced engineering environmentsPrototype-heavy, fast-moving programmesExperience delivering hardware against demanding technical schedulesSeniority ExpectationsLeads designs end-to-end with minimal supervisionComfortable making architectural and technical trade-offsDrives design reviews and delivery timelinesActs as a mentor and technical reference for othersTakes ownership for outcomes, not just tasksPackage & Benefits (UK)Competitive base salary: £60,000-£70,000 (higher for Lead/Principal profiles)Annual bonus schemePension with strong employer contribution, increasing with serviceShare / SIP schemePrivate medical insurance and health cash planLife assurance and income protectionFree on-site gym and discounted national membershipsElectric car salary sacrifice scheme26 days holiday plus bank holidays, with option to buy additional daysWorking PatternPredominantly on-site role due to lab, rig and prototype requirementsTypically 4-5 days on site, with limited flexibility for remote design or admin workOccasional extended hours aligned to testing or integration milestonesMinimal travel, primarily UK-based test facilitiesWhy This RoleThis position offers genuine ECU hardware ownership, advanced EV and battery exposure, and the pace of motorsport engineering combined with long-term stability and investment. It is suited to engineers who want to design, touch, test and improve real hardware - not manage it at arm's length.To find out more about Computer Futures please visit JBRP1_UKTJ
