Job description

Sepura TETRA digital radio products are similar to mobile phones, but also provide robust, long range, secure communication in harsh environments to public safety, military, transport, utilities and commercial customers. Sepura offers a broad range of radio products, support tools and accessories. Our next generation products will need to meet similar requirements but will need to utilise broadband communication and platform technologies.

This role will focus on the development, configuration and tuning of Sepura’s Mission Critical Services, the broadband-based communication standard that forms the core technology for the UK's new Emergency Services Network (ESN).

Ideally, candidates will be able to demonstrate previous experience gained over the full software development life‑cycle.

Come and join Sepura Ltd at an exciting time of growth and progress and develop your career within this innovative technology company, based in Waterbeach, Cambridge.

Role

Reporting to the Services Team Leader, this role will focus on the development of embedded application software components for digital radio products and their accessories.

Previous application software development experience on an embedded Linux/Android platform of a released commercial product is essential.

You will have a good understanding of embedded telecommunications environment and mobile technology, as well as possessing strong communication skills and be comfortable discussing ideas and solutions with others to successfully design new components and resolve issues in legacy components.

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.
