Senior Systems Design Engineer

We are seeking a highly experienced Senior Systems Design Engineer, based in Brackley who has deep expertise in mixed-signal hardware design and embedded C programming. Our client is a leading designer and manufacturer specialising in prototype development and custom PCB assembly.

This is a multidisciplinary role ideal for a senior engineer who thrives in a hands-on technical environment, integrating analogue and digital circuit design with real-time embedded software to deliver robust, scalable solutions.

Key Responsibilities for the Senior Systems Design Engineer job based in Brackley;

• Lead the architecture, design, and development of mixed-signal electronic systems (analogue/digital interfaces, microcontrollers, sensors, power management).
• Develop and debug embedded software in C for real-time control, data acquisition, and communication tasks.
• Design PCBs using industry-standard tools (e.G., Altium, KiCad, OrCAD), including schematic capture, layout reviews, and BOM generation.
• Perform system-level integration, verification, and validation across hardware and software components.
• Collaborate with cross-functional teams (mechanical, firmware, software, test) to define requirements and ensure seamless system integration.
• Conduct design reviews, FMEA, and documentation for regulatory and manufacturing compliance (e.G., CE, EMC).

Skills & Experience needed for the Senior Systems Design Engineer job based in Brackley;

• Degree in Electronic Engineering, Computer Engineering, or related discipline.
• Extensive experience in electronic system design with a strong focus on mixed-signal electronics and embedded C.
• Proficiency in embedded C for bare-metal or RTOS-based systems (e.G., ARM Cortex-M, STM32, MSP430, etc.).
• Experience designing analogue front-ends (ADC, op-amps, filters), power supplies (LDOs, switching regulators), and digital buses (I2C, SPI, UART, CAN).
• Strong debugging skills using tools like oscilloscopes, logic analysers, and JTAG/SWD debuggers.
• Solid understanding of PCB layout principles for signal integrity, EMC/EMI, and thermal considerations.

Desirable:

Experience with low-power embedded systems, sensor interfacing, or wireless comms (e.G., BLE, LoRa, Zigbee).
