Mixed Signal Electronics Engineer

Mixed Signal Electronics Engineer (PCB and Analog) – Oxford

Location: Oxfordshire
Employment Type: Full-time, permanent

***PCB, Analog, PCBA, RF***

About the Role

An exciting opportunity has arisen for a Mixed Signal Electronics Engineer (PCB and Analog) to join a cutting-edge technology organisation based in Oxford. You’ll be part of a multi-disciplinary engineering team developing advanced electronic systems that bridge the digital and analogue domains. This role involves taking designs from concept through to production, contributing to the development of innovative, high-performance hardware platforms.

Key Responsibilities

• Design and develop mixed-signal electronic systems integrating analogue and digital components.
• Translate functional requirements into PCBA-level implementations.
• Perform modelling, simulation, and analytical calculations to ensure optimal performance and system stability.
• Conduct PCB design and layout, ensuring signal integrity and efficient routing.
• Prepare manufacturing documentation and fabrication files for PCB production.
• Build and test prototype boards, diagnosing and resolving design issues.
• Develop and execute test plans to verify designs against performance specifications.
• Collaborate with other engineering disciplines to integrate mixed-signal designs into larger systems.
• Support supplier selection and component sourcing as required.

Required Skills & Experience

• Degree (or equivalent experience) in Electrical Engineering, Electronics, or a related discipline.
• Strong understanding of analogue, digital, and mixed-signal circuit design principles.
• Proven experience managing the full PCB design lifecycle, from specification to manufacturing.
• Proficiency with PCB design tools (e.g., Altium) and simulation software (e.g., SPICE).
• Hands-on experience with electronics lab equipment such as oscilloscopes, spectrum analysers, and network analysers.
• Experience in prototype assembly and PCB rework.
• Strong problem-solving and debugging skills.
• Effective communication and teamwork abilities within cross-functional engineering environments.

Desirable Skills

• Knowledge of digital signal processing (DSP) techniques.
• Experience with RF or high-speed mixed-signal design.
• Familiarity with microcontroller programming or FPGA development.
• Understanding of product lifecycle management from concept to production.
• Experience with digital communication protocols such as SPI, I²C, UART, and Ethernet.
