Our revolutionary Nanoimager and Aplo Scope stand at the forefront of advancing cellular studies on a molecular level, making substantial contributions to the evolution of scientific knowledge.\nWe are actively seeking an enthusiastic and self-motivated Senior Electronics & Systems Engineer to join our pioneering team located in Oxford. We believe in the power of relentless curiosity and the pursuit of excellence, and we invite you to join us in shaping the future of scientific exploration and healthcare breakthroughs.\nIn this role you will be the go-to technical resource for electronics design, working closely with engineering, software and R&D product teams. Electronics design is at the core of the role, but we are looking for someone who enjoys working beyond the boundaries of the PCB - developing embedded firmware, integrating sensors and actuators, and understanding how electronics interact with optics, mechanics, software and the physical world.\nYou will have significant technical ownership across the product lifecycle, from circuit and system design through prototyping, bring-up, verification and production. You will also develop production firmware and work further up the software stack where needed to integrate, automate and test the systems you develop.\nThe role is ideal for an engineer who enjoys solving complex multidisciplinary problems, takes ownership of product outcomes and thrives in a collaborative, fast-paced environment.\nYour role at ONI:\nOwn electronics designs from concept through architecture, schematic design, PCB development, bring-up, verification and production.\nDesign robust analogue and digital electronics, including power supplies, signal conditioning, sensor interfaces, communications and control electronics.\nMake appropriate component and architecture choices, balancing performance, cost, availability, manufacturability and product requirements.\nUndertake PCB design and layout as an integral part of electronics development, working with external PCB designers where appropriate, and considering signal integrity, grounding, noise, EMC/ESD, thermal performance and DFM/DFT.\nWork with manufacturing partners and suppliers to ensure designs are manufacturable, testable and robust through production.\nBring up new hardware and systematically debug complex problems using oscilloscopes, logic analysers, hardware debuggers and other laboratory instrumentation.\nDevelop and maintain production embedded firmware, typically for microcontrollers, alongside low-level firmware for hardware bring-up, control, test and diagnostics.\nDevelop and debug interfaces to sensors, actuators and other hardware, including analogue front ends, ADCs/DACs and common digital communication interfaces.\nWork with optical and mechanical engineers on optoelectronic and physical-system interfaces, such as photodetectors, lasers and other light sources, cameras, position and temperature sensing, motors, piezos and other actuators.\nDiagnose issues whose root cause may lie in electronics, firmware, sensors, optics, mechanics, cabling, software or the interactions between them.\nDevelop test and automation tools, including Python-based instrumentation, hardware testing and manufacturing QA.\nSupport verification, EMC/compliance testing, production test, calibration and transfer of designs into manufacture.\nSupport electronics throughout the product lifecycle, including investigation of product and manufacturing issues, root-cause analysis, component obsolescence and design changes.\nApply modern software engineering practices including source control, automated testing and CI/CD, and make effective use of AI-assisted development tools and coding agents to extend and accelerate your capabilities beyond electronics.\nWe'd expect experience in many of the following:\nStrong analogue and digital circuit design fundamentals.\nSchematic capture, PCB layout and development of multilayer PCBs.\nPower supply design, power distribution, protection and power sequencing.\nLow-noise electronics, grounding, shielding and signal integrity.\nSensor interfacing, analogue signal conditioning, amplification, filtering and data conversion.\nMicrocontrollers and embedded systems.\nEmbedded C/C++, including development of robust production firmware and low-level peripheral control, interrupts, timers, DMA and real-time behaviour.\nDeveloping from device datasheets and MCU/SoC reference manuals rather than relying solely on high-level libraries.\nInterfaces such as SPI, I²C, UART, CAN, USB and Ethernet.\nPractical board bring-up and fault-finding using oscilloscopes, logic analysers, multimeters and hardware debuggers.\nDesign for EMC, ESD, reliability, manufacturability and test.\nTaking electronics through prototype, verification, certification and production.\nGit and modern software development practices, and Python or similar for test, automation and instrumentation.\nWorking effectively across electronics, firmware, mechanical, optical and higher-level software disciplines.\nAdditional desirable experience includes:\nScientific instrumentation, microscopy, imaging or other precision instruments.\nOptoelectronics, including photodiodes, LEDs/lasers, optical power monitoring or camera/image-sensor interfaces.\nPrecision or low-noise analogue electronics.\nMotion control, motors, encoders, piezo actuators or feedback/control systems.\nHigh-speed data acquisition or communications.\nProduction test fixtures, calibration systems and manufacturing automation.\nSystem-level debugging across complex multidisciplinary systems, including electronics, firmware, optics, mechanics and software.\nUsing coding agents or other AI-assisted development tools to build test, automation or hardware-control applications.","description_format":"text","description_chars":6018,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Biotechnology","Network
