Principal Linux/Android Platform Developer

It's an exciting time to come and join the Sepura team. We are on the lookout for Linux/Android Platform Developers to play a key role within the Software Team .

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 offer 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 the Android platform, Android framework/service alterations, and the Android development toolchain. Whilst experience of developing Android Apps is useful, this is not an Android App developer role.

Ideally, candidates will be able to demonstrate previous experience gained over the full development life-cycle of a released Android product. You will have a strong background in the development of Linux and Android based battery powered embedded systems. You will be capable of working in the Linux kernel and ASOP source trees. You will also be comfortable managing large code bases and confident using git to merge branches and upstream commits.

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

Role

Specific responsibilities may include:

• Android platform development, kernel configuration including modifications to the scheduler, performance optimisations and minimising latencies.

• Prototyping of demonstration systems to generate early feedback on proposed solutions.
• The production of architectural, design and test specifications.

• Participation in project planning and technical reviews.

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.
