FULL DESCRIPTION

[Employer hidden — view at passion-project.co.uk] is seeking a Senior Software Engineer to work on their Contacts team. The role involves scaling up and building a world-class recipient management product, collaborating with designers, product managers, and analysts in an agile environment. The ideal candidate should have experience with large-scale distributed systems, Java 8+, relational and non-relational databases, and RESTful APIs.

Job Description

The Contacts team is a core team at [Employer hidden], dedicated to making adding, finding, and managing your recipients as easy as possible.

The team is integral to [Employer hidden]’s day-to-day operations — if our services go down, [Employer hidden] goes down.
