What you’ll be doing…

As a Backend Software Engineer, you’ll support the build of elegant, performant, maintainable, operable, and secure Golang microservices. The role is to support the integration of Curve into LBG and the launch of the Lloyds Wallet and Pi3 too. You’ll help design and architect our systems, contribute to continuous improvement, and play a key role in making the engineering team the best it can be. You’ll be delivering clean, architecturally sound and maintainable server-side code (and if you’ve got full-stack experience, that’s a definite plus). You’ll work closely with stakeholders across the business to build, measure and learn as you help shape a world-class product. You’ll partner with product and engineering managers to keep refining how we build and ship, and you’ll help the team push through roadblocks so features land as effectively as possible. Along the way, you’ll guide design discussions and help balance flexibility, speed, scalability and performance. You’ll also champion new technologies, promote strong development practices, and keep an eye on what’s coming next—proactively (but pragmatically) tackling technical debt.

Why Join us?

If you think all banks are the same, you’re wrong. We’re a pioneering, fast-changing business that’s shaping finance as a force for good. If you’re after a role where you can have an impact and do the best work of your career, you’ve just found it.

What we’re looking for:

• 5+ years’ experience and in-depth knowledge of Golang (experience with PHP is a plus).
• Experience building microservices, ideally deployed in containers on Kubernetes.
• Solid grounding in agile development practices.
• Experience with both RDBMS and NoSQL datastores.
• Ability to diagnose problems across the stack (client, HTTP/network, server, database, OS) with sound rationale for decisions.
• Proven experience building large, concurrent, distributed applications.
• Experience developing and running large-scale production environments in partnership with DevOps or SRE teams.
• A genuine interest in working in a fast-paced startup, ideally in fintech or payments.

And any experience of these would be great…

• Experience with event-driven architectures.
• Experience mentoring or coaching other engineers.
• Experience with real-time, low-latency, high-frequency transaction-based systems.

We know that great talent comes from many backgrounds. Whilst this job advert may reference specific years of experience, we recognise that skills are developed in many ways, so if you have relevant, transferable experience, we encourage you to apply.
