Job Description

Join our engineering team to build real-time AI Native workflows, tooling, and interfaces that will reshape how developers create and maintain software.

This is a product engineering role with a platform twist. Most of your time, you'll do what every Tessl engineer does: design, prototype and ship product features end to end, collaborating closely with product, design and the wider engineering team in a fast-paced, high-autonomy environment. What makes you different is that when the work goes below the application layer, you light up rather than back away: complex networking scenarios such as site-to-site VPN and private connectivity, multi-cloud and multi-region deployments, observability, and the machinery that makes Tessl straightforward to deploy, operate and support wherever it needs to run.

We expect you to be relentlessly AI native about it: instead of triaging alerts at 2 am, you'll build or deploy the agent that does it. Instead of reacting to scaling bottlenecks, you'll create systems that spot them before they happen. Deep expertise is the foundation, because you can't automate what you don't know, but your ambition should be to make agents do the bulk of the operational work, with you supervising and steering.

We're open on level for this role, from mid-level to senior: trajectory and appetite matter more to us than years.

What success looks like: Within your first year, you're shipping product features end to end like any Tessl engineer. When infrastructure work arises, from deployment architecture to networking to observability, you're the one who takes it on and lands it well, with support where you need it. Our deployment and operational practices are stronger because of you, agentic tooling handles a growing share of the toil, and the infrastructure work you touch is compliant by default, keeping our ISO 27001 and SOC 2 journey unblocked.


What you'll do

No two days will be the same at Tessl! You'll have a high level of autonomy and be empowered to make decisions based on what you believe will help you deliver the most success. Here's an insight into just a few of the things you would be doing:

Product engineering (most of your time)

  • Design and implement new functionality end to end, from initial design and prototypes to fully scoped production implementations, reviewed with the product team
  • Rapidly prototype new capabilities to prove or disprove an idea, then develop a plan for a scalable implementation
  • Pair with designers and other engineers to make the experience intuitive and slick, and integrate third-party services so we can focus our cycles on Tessl's core capabilities
  • Gather requirements from customers and stakeholders, turn ambiguity into agreed plans, and deliver them

Platform & infrastructure

  • Lean into infrastructure work as it arises: our AWS estate (EKS/Kubernetes), infrastructure-as-code, CI/CD with GitHub Actions, and our observability stack (Dash0/OpenTelemetry, Sentry, PostHog)
  • Contribute to the architecture & build of our more complex networking and deployment scenarios, such as private connectivity and multi-region setups
  • Improve developer experience and platform ergonomics so every engineer at Tessl ships faster
  • Partner with our Infosec team so that everything you build is compliant by default, contributing infrastructure controls and evidence towards ISO 27001 and SOC 2

AI-native automation

  • Build or deploy agentic tooling that picks up firing alerts and works through diagnostic steps autonomously, giving a human supervisor a detailed assessment with recommended actions
  • Build agents that keep our estate healthy without human toil: dependency upgrades that test and merge themselves, alerts that arrive pre-diagnosed, runbooks that execute instead of sitting in a wiki
  • Continuously spot repetitive manual work, across product, platform and on-call workflows, and convert it into agent-driven automation

What we're looking for

We're looking for someone who is as excited as we are to be part of a dynamic team that is shaping the future of AI and software development.

Must-haves

  • Proven experience as a Software Engineer (TypeScript/Node preferred): you care about code modularity, structure and aesthetics, and you're equally comfortable contributing to a mature codebase with strict CI criteria or hacking up a quick prototype to prove an assumption
  • A genuine pull towards platform and infrastructure work, backed by hands-on experience: you've deployed and operated real systems (Kubernetes, cloud environments, infrastructure-as-code, CI/CD), and when the chance came to go deeper, you took it, whether that was owning platform or DevOps work in a previous role or picking up the infrastructure tasks nobody else wanted
  • Solid systems and networking fundamentals: DNS, TLS, VPCs, firewalls; you can reason and debug below the application layer with confidence
  • Demonstrated use of AI coding tools and agents to accelerate your own work, and excitement about experimenting with new AI approaches to transform how engineering is done
  • Comfortable with fast-paced, high-autonomy environments: you turn loose requirements into plans and shipped work without waiting to be told

Nice-to-haves

  • You self-host things for fun: a homelab, your own services, a Kubernetes cluster nobody asked you to run
  • Production AWS/EKS experience, or hands-on work with private connectivity, VPNs, or multi-region architectures
  • Experience producing infrastructure evidence for certifications such as ISO 27001 or SOC 2
  • You've thrived in an early-stage startup before
  • Have a cool project to show us (GitHub links welcome!)

The kind of person you are

  • You're a product engineer first: you measure infrastructure by what it lets the team ship, and you see platform work as making every engineer faster, never a domain to guard
  • You're calm under pressure, including when production is misbehaving and the answer is three layers down the stack
  • You think big about how AI changes the job: the best engineers automate themselves out of the repetitive loop and operate at the scale of a team
  • You're comfortable with ambiguity and rapid change, and you grab a shovel when something needs doing outside your lane
  • You communicate clearly and bring people along: product, security, engineers and customers all need to trust your judgement

Company Benefits

  • We offer a competitive salary commensurate with experience and skills.
  • We provide health insurance which extends to partners and dependents, as well as a pension.
  • Our office is based a couple of minutes away from King’s Cross station.
  • We have regular socials such as team lunches, drinks and more.
  • Whilst we’re in building mode, currently all employees aim to be in the office 3 days a week - regularly Monday, Tuesday and Thursday.

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 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.

  • Stage 2 - Take home challenge
  • Stage 3 - 90 mins technical interview with two team members
