I am currently recruiting for a market leader in the field of critical communications. Their focus is on providing high quality products to a demanding, mission critical client base, which includes the police, paramedics, sea rescue, major airports, large mining facilities and utilities or oil and gas plants located in hazardous environments.

We are looking for a Senior Baseband Engineer, who can make a significant contribution to the design and development of TETRA/Broadband radio equipment, accessories, tools and services provided to customers.

You will be responsible for:

• Designing intrinsic safety (IS) circuitry for ATEX certified products.
• Developing advanced microprocessor-based systems, integrating a wide range of sensors (accelerometers, magnetometers, proximity detectors, gyroscopes, and barometers) to support mission critical functionality.
• Designing high efficiency, low power power supply architectures, ensuring robust performance across challenging operational environments.
• Creating and validating audio amplifier designs up to 10 W, optimising for clarity, efficiency, and reliability.
• Conducting design verification and system level testing, including EMC validation, to ensure compliance with internal standards and external regulatory requirements.
• Producing high quality engineering documentation, including functional specifications, detailed design descriptions, and supporting artefacts for modules and complete product assemblies.

Key Skills Needed:

• A bachelor’s degree in a relevant engineering discipline, or equivalent industry experience demonstrating strong technical capability.
• Proven experience developing products for ATEX‑certified environments, with a solid understanding of intrinsic safety principles and compliance pathways.
• Strong written communication skills, with the ability to produce clear, accurate, and structured technical documentation.
• Expertise in microprocessor system design, including power‑supply requirements, low‑power architectures, and power‑saving strategies.
• Proficiency with key serial communication interfaces, including I²S, I²C, UART, and USB (with USB 3.0 experience considered especially valuable).

This is a full-time, onsite position (37-hour work week) based out of their North Cambridge office.
