Senior Electronics & Systems Engineer

Your Role At Oni:

• Own electronics designs from concept through architecture, schematic design, PCB development, bring-up, verification and production.

• Design robust analogue and digital electronics, including power supplies, signal conditioning, sensor interfaces, communications and control electronics.

• Make appropriate component and architecture choices, balancing performance, cost, availability, manufacturability and product requirements.

• Undertake 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.

• Work with manufacturing partners and suppliers to ensure designs are manufacturable, testable and robust through production.

• Bring up new hardware and systematically debug complex problems using oscilloscopes, logic analysers, hardware debuggers and other laboratory instrumentation.

• Develop and maintain production embedded firmware, typically for microcontrollers, alongside low-level firmware for hardware bring-up, control, test and diagnostics.

• Develop and debug interfaces to sensors, actuators and other hardware, including analogue front ends, ADCs/DACs and common digital communication interfaces.

• Work 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.

• Diagnose issues whose root cause may lie in electronics, firmware, sensors, optics, mechanics, cabling, software or the interactions between them.

• Develop test and automation tools, including Python-based instrumentation, hardware testing and manufacturing QA.

• Support verification, EMC/compliance testing, production test, calibration and transfer of designs into manufacture.

• Support electronics throughout the product lifecycle, including investigation of product and manufacturing issues, root-cause analysis, component obsolescence and design changes.

• Apply 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.

We'd Expect Experience In Many Of The Following:

• Strong analogue and digital circuit design fundamentals.

• Schematic capture, PCB layout and development of multilayer PCBs.

• Power supply design, power distribution, protection and power sequencing.

• Low-noise electronics, grounding, shielding and signal integrity.

• Sensor interfacing, analogue signal conditioning, amplification, filtering and data conversion.

• Microcontrollers and embedded systems.

• Embedded C/C++, including development of robust production firmware and low-level peripheral control, interrupts, timers, DMA and real-time behaviour.

• Developing from device datasheets and MCU/SoC reference manuals rather than relying solely on high-level libraries.

• Interfaces such as SPI, I²C, UART, CAN, USB and Ethernet.

• Practical board bring-up and fault-finding using oscilloscopes, logic analysers, multimeters and hardware debuggers.

• Design for EMC, ESD, reliability, manufacturability and test.

• Taking electronics through prototype, verification, certification and production.

• Git and modern software development practices, and Python or similar for test, automation and instrumentation.

• Working effectively across electronics, firmware, mechanical, optical and higher-level software disciplines.
