About the Organisation:
Our client is an established, high-technology electronics and engineering business headquartered in Oxfordshire, operating across commercial, government, and defence markets. The organisation designs, manufactures, and delivers advanced RF, fibre optic, and sensing systems for applications including satellite ground stations, broadcast infrastructure, secure communications, and defence platforms.
With a workforce of approximately 80 and a dedicated engineering team of 30, the business has achieved consistent and strong financial growth in recent years. As part of a larger, well-capitalised parent group, the organisation benefits from increased investment and expanded market access whilst retaining operational autonomy, agility, and an entrepreneurial culture. The company holds Gold Investors in People accreditation and is certified to ISO 9001.
Role Overview:
Software capability has become increasingly central to the organisation's product strategy. Over the past 18–24 months, the business has transitioned from short-cycle, feature-level software development into the delivery of larger, more complex subsystems with higher technical, architectural, and quality expectations. This role has been created to strengthen the software team's capacity and capability as the business continues to scale.
The Software Design Engineer will work as part of a multidisciplinary engineering team, contributing to higher-level and full-stack software development across embedded device interaction, networked sensor systems, user-facing interfaces, web-based tools, and internal automation systems. The role requires close collaboration with RF, electronics, systems, and hardware engineering disciplines.
This is an application-level development role rather than an embedded firmware position, though regular interaction with embedded systems is integral to the work.
