Job Description

You 9ll be the second senior engineer on a platform that 9s already live across local authorities and NHS pathways - pairing directly with the engineer who built it from scratch. The foundation is solid; what 9s ahead is the more interesting problem: more AI, more scale, new care pathways. You 9ll help set the engineering direction on a full-stack Kotlin platform, with the autonomy of a startup and the contracts and reach of a major care provider behind you.

What 9s ahead is the more interesting problem: more AI, more scale, new care pathways. You 9ll help set the engineering direction on a full-stack Kotlin platform, with the autonomy of a startup and the contracts and reach of a major care provider already behind you.


Responsibilities

  • Shape the technical roadmap with the existing dev team and the MD - architecture decisions, build-vs-buy calls, tooling choices. We make these calls together, not in a vacuum.
  • Ship fullstack Kotlin across the backend (APIs, data pipelines, NHS/LA integrations), the care portal (web), and the robot app (Android).
  • Sit with ops. Understand how carers and care managers actually use the platform and build from that.
  • Integrate AI capabilities like virtual AI calls, predictive alerts and falls detection. We work with AI partners and need someone who can wire it together end to end.
  • Push agentic coding practices (Claude Code, Copilot, Cursor) so a small team delivers more than its size suggests.
  • Keep the lights on: CI/CD, testing, observability, AWS. Small team, so you 9ll touch everything.

Qualifications and Skills

The codebase is Kotlin Multiplatform and that 9s where we want the leverage on this contract, so we 7re looking for a Kotlin-first fullstack engineer. Longer term we may be more stack-agnostic.

  • Backend: Ktor, Spring Boot, or similar. API design, databases. AWS: CI/CD, containers, infrastructure-as-code. Hands-on.
  • Frontend: Kotlin/JS, Compose for Web.
  • Willing to work across the full stack, Android included. You don 7t need deep mobile experience, but you 7re up for getting your hands dirty on the robot app when needed.
  • Strategic instinct. You think about where the platform should be in 12 months, not just what 7s in the current sprint.
  • Ops empathy. You care about how the product is deployed and used, and you go looking for that context.
  • Agentic coding as your default. 70%+ of your daily work already runs through Claude Code, Copilot, or Cursor, and you can point to what that 7s enabled.
  • Pace. You ship, you iterate, and you don 7t wait for permission.

Carries Real Weight

  • Regulated industry experience in health tech, social care, or fintech. Not essential, but if you already understand compliance, data governance and audit trails you 7ll get up to speed faster.
  • Kotlin Multiplatform (KMP) experience.
  • CQC, NHS Digital, or DTAC frameworks.
  • IoT protocols and device management at scale.
  • Building LLM-powered features in production and configuration.
  • Cloud service orchestration experience.
  • Background in robotics or assistive tech.

Beyond the technical skills, we are looking for:

  • AI-native by default. Claude Code, Copilot, Cursor - these are already how you work, not tools you 7re evaluating. You can point to what they 7ve unlocked for you.
  • Ownership instinct. You see a problem and take it. You don 7t wait to be assigned. Prioritise issues yourself and move them forward without needing handholding.
  • Pragmatism. You ship the smallest thing that works, then iterate. Done beats perfect. Prioritise the work that delivers value fastest, then improve it from there.
  • Business curiosity. You go find out how the work actually happens, not just how the spec describes it.
  • Learning speed. The stack changes. You don 7t get attached to what you learned last year.
  • Low ego. You can be wrong, change course, and give credit where it 7s due.

These aren 7t required, but they 7ll make you stand out:

  • Regulated industry experience (health tech, social care, fintech, defence). Compliance and audit-aware engineering shortens ramp time.
  • NHS-adjacent stack experience: FHIR UK Core, OMOP, SNOMED CT, GP Connect, DTAC.
  • Building LLM-powered features in production, evals, drift monitoring, observability.
  • Scheduling, matching, or constraint-solving algorithms at production scale.
  • Tele-ICU-like, command-centre, or supervised-automation systems from any domain.

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.

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
