Senior Electronics & Embedded Software Engineer Location: Filton, Bristol / Hybrid Contract: 12 months Start Date : ASAP Pay Rate: £75 - £85 per hour Inside IR35 About the Role We are looking for a Senior Electronics & Embedded Software Engineer to design, develop, and maintain advanced embedded systems for a jet engine Blade Inspection Tool (BIT) product suite. This role combines embedded firmware development, electronics/PCB design, and hands-on prototyping, with a strong focus on custom camera modules and LED strobing systems. You will work on both a matured legacy product and a new hardware platform, collaborating with internal teams and external camera vendors to deliver reliable and production-ready solutions. Key Responsibilities Embedded Software & Firmware Development Develop, test, and debug embedded firmware in C/C++ for microcontrollers, including bootloaders. Implement and maintain device drivers for peripherals such as I2C, SPI, UART, USB, ADC, PWM, and others as required. Implement serial communication protocols for interfacing with embedded boards and host systems.Electronics & PCB Design Design schematics for small embedded systems, custom camera interfaces, and development boards. Perform PCB layout, including component placement and routing, with a focus on miniaturized boards. Design and review LED driver circuitry and associated control electronics for pulsed/strobing operation. Work with high-speed interfaces such as USB2.0 & USB3.0 in PCB layouts.Prototyping, Testing & Debugging Assemble and test electronic prototypes and development boards. Perform hand soldering and rework of SMD components, including fine-pitch and miniaturized PCBs. Use lab equipment (oscilloscope, logic analyser, power supplies, etc.) to debug hardware and firmware issues. Build simple development and test boards to support ongoing R&D and validation activities. Support QA, validation, and verification of prototype cameras and embedded systems.Documentation, Collaboration & Delivery Maintain clear, traceable documentation including schematics, PCB revisions, firmware versions, and test reports. Collaborate closely with mechanical engineers, manufacturing partners, and external vendors to ensure robust, manufacturable designs. Support the transition from prototype to small-scale and volume production, including design-for-manufacture (DFM) and design-for-test (DFT) considerations. Participate in design reviews and provide technical input on requirements, specifications, and architecture. To apply, please send your CVs in the first instance
