R&D Systems and Design Engineer Electronics CAD and Prototyping

I am an R&D-focused Systems and Design Engineer with a strong practical background in electronics, CAD, and prototype development. I specialise in taking early-stage ideas or unclear requirements and turning them into working, testable engineering solutions. My experience spans electronics design, embedded systems, sensor integration, CAD-based mechanical design, and experimental test environments. I have worked in automotive and industrial contexts, supporting R&D activities through structured testing, data logging, and validation. I work best on technically challenging problems that require logical thinking, independence, and attention to detail. Clients value my ability to ask the right questions early, avoid over-engineering, and deliver robust prototypes that are ready for testing or iteration. I am particularly well-suited to: Early-stage R&D and feasibility work Electronics and sensor-based prototype development Mechanical–electronic integration challenges Engineering support where clarity and structure are needed I am UK-based, communicate clearly, and take a calm, methodical approach to problem solving.
