Job description

19th December 2025

Fancy being part of a collaborative, forward‑thinking global leader in critical communication solutions? Here at Sepura Ltd we are currently recruiting for a Product Definition Engineer to join our expanding team. Sepura is at the forefront of mission critical communications. Our market‑leading advanced radios* are specifically designed to help customers all over the world do their jobs better. The product definition engineer plays a key role in this by ensuring our products behave as customers require. Come and join Sepura Ltd at an exciting time of growth and progress your career within this innovative technology company, based in Waterbeach, Cambridge. *Note: An advanced radio is a cross between a walkie‑talkie and a mobile phone. They are typically used by emergency services, transport, mining, and other sectors.

Role

In this post‑graduate role, you will be part of Sepura's Product Definition team. You will be provided with on‑the‑job training to help define the detailed behaviour of Sepura's advanced radio products and tools. You will be writing feature specification documents that inform the designs of software engineers and the plans of system testers. As you build knowledge and experience you will work with a variety of business stakeholders including Product Managers, Senior Development Engineers, System Testers, Customer Support Engineers, and the wider business to:

• understand product requirements
• develop the requirements into a definition of product behaviour
• document the behaviour on behalf of business stakeholders
• maintain the documentation and incorporate change

In time you will become the custodian of the developed requirements, disseminate them to stakeholders throughout the organisation, and become one of the go‑to knowledge experts on our products and features. You will assist Product Owners (who are also part of our team), helping them understand product functionality. This also offers an excellent opportunity to train as a Product Owner.

Day to Day

Our customer base includes many different industries and markets around the world. Our complete TETRA and LTE solutions have been developed specifically for users in multiple sectors to face their critical communications challenges. There is no such thing as a typical day here at Sepura. You will be supported by your manager and team, as well as collaborating with other departments across the business. Definition Engineer activities you will be responsible for include:

• understand in depth feature, product, and system requirements, and in doing so help clarify functionality and the scope of projects
• document and maintain the product and feature definition

This role will require SC clearance
