Opportunities for permanent roles in a range of business sectors

Android Platform Developer

Sepura are seeking a talented Android Platform Engineer to work on our next generation products.

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.

The candidate filling this role will initially work with the Advanced Technology Group to produce reference designs and functional prototypes for Sepura's next generation platforms, and will then transfer to the Development Team to take the ideas and concepts of the prototype through full Product Development. Candidates will need to be flexible enough to thrive in both the dynamic prototyping phase, and the more structured product development phase.

The role will focus on the development, configuration and tuning of the Android platform, creation and integration of custom drivers, and the Android development tools. The candidate will be responsible for monitoring relevant community mailing lists and trialling Android development tools.

A key attribute of the successful candidate will be the ability to enthuse, coach and mentor experienced embedded software engineers whilst they transition to the new environment required for Android development.

Previous experience gained over the full development life-cycle of a released Android product is essential to this role.

Specific responsibilities will include:

  • Android platform development, kernel configuration including modifications to the scheduler, performance optimisations and minimising latencies
  • Trialling and integrating open-source development tools for debugging, profiling, code-coverage, memory leak detection etc.
  • Trialling build tool chains, for subsequent integration into Continuous Integration System
  • Maintenance and enhancements of the Android build and distribution tools
  • Monitoring relevant Android community mailing lists
  • Responsible for writing and maintaining device drivers and low-level software components
  • Rapid prototyping of demonstration systems to generate early feedback on proposed solutions
  • The production of architectural, design and test specifications
  • Integration testing, investigation and resolution of issues
  • Participation in project planning and technical reviews
