Job Description

The role

At Bourn, we’re building financial products that make lending and payments simpler for businesses. Behind those experiences is a growing platform, and a team that cares about doing things thoughtfully - from reliability and developer experience to protecting the people who trust us with their money.

We’re looking for a collaborative engineer who enjoys working across infrastructure and security, sharing ideas and getting hands-on. You’ll help develop our cloud platform while continually improving how we understand, test and strengthen its security as technology and threats evolve.


What you'll be working on

Build and improve our platform: Work on cloud infrastructure, infrastructure as code, Kubernetes, networking, deployment pipelines and operational tooling. Help make our environments resilient, observable and easy for engineers to work with.

Make security a continuous engineering practice: Regularly revisit our systems as they change: review exposure, access, configuration, dependencies and application boundaries; investigate emerging risks; and follow improvements through to implementation and verification. Security is an ongoing responsibility, not a one-off audit.

Test, investigate and improve: Carry out authorised, carefully scoped assessments of our services, APIs and infrastructure. Reproduce findings, understand their real-world impact, prioritise sensibly and work with engineers to deliver lasting fixes.

Explore the next generation of security tooling: Actively seek out and experiment with emerging AI-assisted testing, agentic penetration-testing tools, automated attack-surface discovery and vulnerability analysis. Evaluate what genuinely works, understand its limitations and turn promising experiments into safe, repeatable workflows.

Build security into everyday delivery: Improve automated checks, CI/CD safeguards, monitoring and incident readiness. Make secure choices easier for the whole engineering team without slowing good work down.


The problems are interesting

A new integration changes an exposure path. A dependency develops a vulnerability. An AI testing tool finds something conventional scanning missed - or raises a convincing false positive. A system looks healthy while services cannot communicate. You’ll investigate, test assumptions and help the team make practical improvements.


How we work

We’re a small, approachable engineering team with plenty of autonomy and short feedback loops. You’ll work closely with colleagues building our products, contribute to shared platform responsibilities and have the space to explore new security approaches.

We see security as something we keep learning and improving together. New services, new AI capabilities and new attack techniques mean the work is never finished. We value thoughtful experimentation, clear evidence, sensible safeguards and people who share what they learn.


What we’re looking for
  • Strong platform engineering foundations: Experience with cloud infrastructure, Terraform or similar infrastructure as code, Kubernetes, CI/CD, networking and modern automation tooling, including AI-assisted development and operations.
  • Practical security engineering: Familiarity with identity and access, secrets, certificates, cloud and API security, vulnerability management and common application security risks.
  • Curiosity about modern offensive-security tooling: Hands-on interest in security testing, including emerging AI-powered and agentic tools. You enjoy trying new approaches, comparing results and validating findings rather than taking tool output at face value.
  • A continuous-improvement mindset: You keep up with new vulnerabilities, techniques and tools; make time for experimentation; and look for ways to incorporate useful discoveries into everyday engineering.
  • Ownership and sound judgement: Comfortable tracing a problem from discovery to remediation, assessing risk and knowing when to involve specialist external testers.
  • Collaborative communication: Able to explain technical risks constructively, partner with application engineers and balance security, reliability and developer productivity.

You'd enjoy this role if...
  • You enjoy building and running infrastructure as much as making it safer.
  • You are excited to experiment with new AI security and penetration-testing tools.
  • You like validating findings and making fixes, not just producing reports.
  • You enjoy learning continuously and helping colleagues adopt better practices.
  • You want to help protect financial products used by real businesses.

Job Description

Starling is the UK’s first and leading digital bank on a mission to fix banking! Our vision is fast technology, fair service, and honest values. All at the tap of a phone, all the time.

Starling is the UK’s first and leading digital bank on a mission to fix banking! We built a new kind of bank because we knew technology had the power to help people save, spend and manage their money in a new and transformative way.

We’re a fully licensed UK bank with the culture and spirit of a fast-moving, disruptive tech company. We’re a bank, but better: fairer, easier to use and designed to demystify money for everyone. We employ more than 3,000 people across our London, Southampton, Cardiff and Manchester offices.

Our technologists are at the very heart of Starling and enjoy working in a fast-paced environment that is all about building things, creating new stuff, and disruptive technology that keeps us on the cutting edge of fintech. We operate a flat structure to empower you to make decisions regardless of what your primary responsibilities may be, innovation and collaboration will be at the core of everything you do. Help is never far away in our open culture, you will find support in your team and from across the business, we are in this together!

The way to thrive and shine within Starling is to be a self-driven individual and be able to take full ownership of everything around you: From building things, designing, discovering, to sharing knowledge with your colleagues and making sure all processes are efficient and productive to deliver the best possible results for our customers. Our purpose is underpinned by five Starling values: Listen, Keep It Simple, Do The Right Thing, Own It, and Aim For Greatness.

Hybrid Working

We have a Hybrid approach to working here at Starling - our preference is that you're located within a commutable distance of one of our offices so that we're able to interact and collaborate in person. We don't like to mandate how much you visit the office and work from home, that's to be agreed upon between you and your manager.

Our Data Environment

Our Data teams are excited about the value of data within the business, powers our product decisions to improve things for our customers and enhance effective and agile decision making, regardless of what their primary tech stack may be. Hear from the team in our latest blogs or our case studies with Women in Tech.

We are looking for talented data professionals at all levels to join the team. We value people being engaged and caring about customers, caring about the code they write and the contribution they make to Starling. People with a broad ability to apply themselves to a multitude of problems and challenges, who can work across teams do great things here at Starling, to continue changing banking for good.

Requirements

We have built our entire banking platform in house and mostly in Java. We are looking for people who want to work on building the tooling that is used by our engineers on a daily basis.

We are looking for people who are truly full stack, and are as comfortable polishing their javascript front end as they are debugging the innards of their java applications database interactions, or standing up infrastructure with terraform. We are looking for people who can:

  • Design REST apis.
  • Code backend services, ideally using Java, or another other server side compiled language.
  • Develop modern front ends, ideally using React and Redux.
  • Get their code into the cloud and support it there, ideally on AWS.
  • Believe in clean coding, simple solutions, automated testing and continuous deployment.
  • Like to take ownership of a feature from the original idea through to live.
  • Think (like us) that a small number of empowered developers is the right way to deliver software.

Company Benefits

  • 33 days holiday (including flexible bank holidays)
  • An extra day’s holiday for your birthday
  • 16 hours paid volunteering time a year
  • Part-time and/or flexible hours available for most roles
  • Salary sacrifice, company enhanced pension scheme
  • Life insurance at 4x your salary
  • Hybrid/remote working
  • Private Medical Insurance with VitalityHealth including mental health support and cancer care. Partner benefits include discounts with Waitrose, Mr&Mrs Smith and Peloton
  • Generous family-friendly policies
  • Varied social groups set up and run by our employees
  • Perkbox membership giving access to retail discounts, a wellness platform for physical and mental health, and weekly free and boosted perks
  • Access to initiatives like Cycle to Work, Salary Sacrificed Gym partnerships and Electric Vehicle (EV) leasing

Full details are available on our careers site

Interview Process

Interviewing is a two way process and we want you to have the time and opportunity to get to know us, as much as we are getting to know you! Our interviews are conversational and we want to get the best from you, so come with questions and be curious. In general you can expect the below, following a chat with one of our Talent Team:

  • Stage 1 - 30 mins with one of the team
  • Stage 2 - Take home challenge
  • Stage 3 - 90 mins technical interview with two team members
  • Stage 3 - 45 min final with an executive and a member of the people team
