You'll be leading one of our three product squads — a multi-skilled team usually consisting of Back End, Front-End, QA, UX Designers, Content Creators, and a Product Manager, supported by other leads and Staff Engineers. When it comes to culture - we really try to build cohesive, high performing teams that pull together. Each squad feels a real sense of ownership over their work. Building an environment based on trust and honesty is really important to us, enabling squads and individuals to grow and develop. As a lead backend engineer, your time will be split between coaching other backend developers within the team, steering our backend architecture and providing oversight on the back end tasks for our backlog items - delivering some independently and some through coaching others. As we work in multidisciplinary squads, ideally you will also be able to support others doing Front End, QA, DevOps (etc) work to make sure we hit our sprint goals. Your new development will be done within a Microservices architecture, but you will also be contributing to our legacy systems while we are in the transition period. Our stack runs on Azure — including Front Door, App Services, Application Insights, and App Configuration — with SQL Server and Cosmos DB for data and Azure Service Bus for messaging between services. Outside of squad work you will be part of the Back End Chapter. We hold Chapter meetings to talk about tech and ways of working. We work democratically to evolve our stack and make constant improvements. What Skills Are You Bringing To The Team?
