Senior Software Development Engineer

Senior Software Development Engineer


We are looking for Senior Software Engineers as we embark on a journey involving DevOps, Microservices and Machine Learning. Engineers who have an understanding of micro services, planning and architecting, developing, testing, releasing and operating. We are looking for Engineers who are able to talk about what they have done and how we develop as a team. We’re not asking you to manage people. We’re recognising you as senior because you relish a responsibility for leading our technology rather than leading our colleagues. You will be key in designing, guiding and implementing modern technology choices as we move our technology stack away from monolithic applications to a modern microservices based architecture.

In terms of language, we don’t say “just Java”. We are seeking an open minded approach to languages, and as a Senior Software Engineer you should be able to identify what language is good for what approach. Let’s not use Java for ingest services if Python is quicker – but you get to make that choice. In terms of tech, we’re building a new Argos, bit by bit (or byte by byte!). And we’re keeping up with business-critical changes on our existing tech while we do it.

We need engineers with excellent knowledge of testing frameworks, setting up event-driven development, message queues etc. As a Senior Software Engineer you will be at the forefront of driving our technology and ways of working. You’ll have a supportive manager who is likely to be very technical themselves – isn’t that a refreshing change?
