At Engine by Starling, we don't do "checkbox security"—we build security software. We treat security as a first-class engineering discipline, where the solution to a threat isn't a policy, but a robust, concurrent system written in Go
As a Cloud Security Software Engineer, you will be a hands-on builder responsible for the security architecture of our multi-tenant core banking platform. You’ll spend your days architecting and writing Go-based tooling, automating defenses, and ensuring our infrastructure across AWS and GCP is secure by design and compliant by default.
Your mission is to solve complex security problems through software engineering, focusing on three core pillars:
You will be a key member of our growing Security Engineering team, working at the intersection of Infrastructure, Cross-Cutting, and GRC. We operate like a specialized product team: we identify security friction and build the software to eliminate it. You won’t work in a silo; you’ll collaborate with engineers across the business to deliver a platform that is resilient by default.
We are looking for Software Engineers who are passionate about the Go ecosystem and want to apply those skills to mission-critical security challenges. Whether you come from a Security Engineering background or you are a Backend Engineer with a "security-first" mindset, we value your ability to write clean, maintainable, and efficient code.

Benefits
Hello, we’re Starling.
Banking was broken – so we decided to fix it. The vision? Fast technology, fair service and honest values. All at the tap of a phone, all the time.
We built Britain’s first digital bank.
One hard-won banking licence later, we set about giving people a new way to spend, save and manage their money (and take better care of the planet, too).
We’re changing banking for good.
Back then, we were obsessed with unravelling the knotty world of finance and solving people’s problems rather than selling them stuff. We still are.
Since then, we’ve grown. A lot.
Over four million accounts (and four account types!). A team of thousands. Headquartered in London with offices in Cardiff, Dublin, Manchester and Southampton. Seven years voted Which? Recommended Provider and Britain's Best Banking Brand. Still zero branches.
Our culture is open, inclusive and focused on solving real customer problems, with an emphasis on doing the right thing, even when it’s not always the easy thing. From our approach to working together and sustainability to how we build our products, our decisions need to make the world – and Starling – a better place to be.
Everyone at Starling is essential to our mission, which is really quite simple: to solve our customer’s problems – and build the best bank in the world!
And now we're providing Starling to other banks, via a Software-as-a-Service (SaaS) proposition through our subsidiary Engine by Starling, using the proprietary technology platform that it uses to power our own bank.
