Job Description

You will design, build, and operate backend and platform services for ACRA, a complex security-focused Kubernetes platform that needs to be reliable, observable, scalable, and secure from the start. You will work primarily in Go, building microservices, APIs, internal platform services, and event-driven systems. You will own services end to end: from system design and implementation through to containerisation, deployment, monitoring, debugging, and production operations. You will help shape the infrastructure and delivery foundations around the platform, including Docker, Kubernetes, CI/CD pipelines, GitOps workflows, container registries, secrets management, deployment automation, and Argo-based delivery flows. You will contribute to core platform primitives such as identity-aware service communication, lifecycle orchestration, policy-driven deployment, auditability, observability, and controlled application execution. ACRA’s architecture separates the control plane, platform enforcement layer, and isolated execution environments, so this role requires someone who can reason clearly about trust boundaries, failure domains, and operational responsibility. This is not a role for someone who only wants to take tickets. We are looking for someone who understands the product vision, challenges assumptions, proposes better designs, and helps translate ambiguous requirements into robust technical systems. As ACRA grows, this role offers a clear path to increasing technical ownership and influence. You will not just build services and move on; you will help maintain, evolve, and scale the systems you own over time. You will also help raise the bar for how we design, review, deploy, operate, and learn as an engineering team. You do not need to have worked with every tool in our stack before. We are looking for strong engineering judgement, curiosity, ownership, and the ability to build reliable systems in complex environments.


What You’ll Do

  • Build and own backend services, APIs, microservices, and platform components in Go.
  • Own services from system design through implementation, deployment, observability, and production operations.
  • Design event-driven, scalable, observable, and resilient systems.
  • Build and improve Docker images, Kubernetes workloads, CI/CD pipelines, and Argo/GitOps workflows.
  • Work with container registries, secrets, secure configuration, and deployment automation.
  • Contribute to platform architecture, system design, security boundaries, and operational models.
  • Help build platform capabilities such as workload isolation, policy enforcement, auditability, and identity-aware communication.
  • Work closely with product, leadership, and engineering to turn ambiguous requirements into reliable technical solutions.
  • Make pragmatic technical trade-offs and explain them clearly.
  • Improve monitoring, logging, tracing, alerting, and production debugging.
  • Raise engineering standards through design reviews, code reviews, documentation, and operational improvements.
  • Operate independently in a startup environment with strong ownership and product thinking.

What We Are Looking For

  • Senior backend engineering experience, ideally with hands-on Go experience.
  • Experience owning production services, not just building features.
  • Experience building APIs, backend services, microservices, or distributed systems.
  • Strong experience with Docker, Kubernetes, and CI/CD.
  • Familiarity with GitOps, Argo, container registries, secrets, and secure deployment workflows.
  • Strong system design fundamentals, especially around reliability, scalability, observability, and failure handling.
  • Ability to reason about security boundaries, operational risk, and production failure modes.
  • Experience debugging issues across applications, services, and infrastructure.
  • Comfort working from ambiguous requirements and shaping the technical approach.
  • Product-minded engineering judgement: you care about why the platform is being built, not just what needs to be implemented.
  • A self-driven, ownership-oriented way of working.
  • Comfortable giving and receiving feedback, reviewing designs, and helping improve team standards.
  • Willingness to work across backend, platform, infrastructure, and DevOps areas.
  • The most important thing is not that you have done everything on this list before. It is that you bring strong engineering judgement, ownership, curiosity, and the determination to build excellent systems.

Company Benefits

  • Basic Life / AD&D and long-term disability insurance 100% covered by Valarian
  • Hybrid work arrangements are managed at team level
  • Generous holiday calendar and PTO
  • Relocation assistance (depending on role eligibility)
  • Competitive salary and equity grants
Employer pension contributions:
  • UK roles include enhanced employer pension contributions
  • US roles include 401(k) retirement savings plan – traditional and Roth
Platinum healthcare benefit:
  • For US roles, we offer comprehensive medical, dental and vision plans at little to no cost to you
  • For UK roles, Valarian will cover the full cost of the Private Medical Insurance (PMI) premium

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.

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.
