Senior Backend Developer

Position: Back-End Development Lead

Location: UK - Fully Remote

Salary: £70,000 - £80,000

We're working with a forward-thinking technology-led organisation that's looking to hire a Senior Back End Developer to join one of their high-performing engineering teams. This is a great opportunity for someone who is passionate about building scalable software, enjoys mentoring others, and wants to play a key role in shaping backend architecture within a modern, agile environment.

The Business places a strong emphasis on continuous improvement both technically and culturally and encourages engineers to explore new technologies, challenge existing ways of working, and contribute to the evolution of their engineering practices.

The Role

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.

You will be part of a Product focussed Technical squad, where the squad is responsible for building, delivering and maintaining fantastic software. This means you will be involved in all stages of your lifecycle from the initial discovery, through planning, build, release and monitoring. You'll be part of all the usual Agile ceremonies and as a team, you will be delivering great new functionality over two-week sprints.

When it comes to culture we really try to build happy, cohesive, performant 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 if something's not right you can be sure your voice will be heard and people will care about what you have to say.

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.
