Job Description

The Opportunity

This is a rare opportunity to build security from the ground up.

As our first Security Engineer, you'll have significant influence over how security is implemented across the business. You'll define security standards, select and implement security tooling, improve engineering processes and work closely with development teams to embed security into our software delivery lifecycle.

This is not a governance-only role.

We're looking for an engineer who enjoys writing code, automating security, working in cloud infrastructure and solving complex technical problems. You'll split your time between improving our security posture and contributing directly to our cloud platform and engineering systems.

If you enjoy building rather than policing, you'll fit in well here.

What You'll Do
Build our Security Capability
  • Develop and evolve the company's security strategy alongside the Head of Security&Cloud Platforms.
  • Design practical security controls that support engineering velocity.
  • Establish security standards, policies and technical guardrails.
  • Introduce security metrics and reporting.
Build Security into our Platform
  • Design secure cloud architectures.
  • Improve identity and access management.
  • Secure Kubernetes workloads and cloud infrastructure.
  • Build automated security controls into CI/CD pipelines.
  • Improve secrets management.
  • Develop security automation and tooling.
Security Tooling

Evaluate, implement and manage technologies such as:

  • Vulnerability Management
  • SAST / DAST / SCA
  • Container Security
  • CSPM
  • Cloud Detection&Response
  • SIEM / Logging
  • Endpoint Detection&Response
  • Secrets Management
  • Infrastructure Scanning
  • Supply Chain Security

The expectation is not that every tool already exists—you'll help determine what we should use.

Engineering

You'll remain a hands-on engineer and contribute to the wider platform by:

  • Building automation
  • Improving developer experience
  • Supporting platform engineering initiatives
  • Contributing to infrastructure as code
  • Reviewing architecture and designs
Security Operations
  • Lead vulnerability remediation initiatives.
  • Improve incident response processes.
  • Support security investigations.
  • Run threat modelling exercises.
  • Coordinate penetration testing.
  • Improve monitoring and detection capabilities.
What We're Looking For

We're less interested in ticking every box than finding someone who enjoys solving difficult technical problems.

You'll probably have experience in many of these areas:

Cloud
  • AWS (preferred)
  • Kubernetes
  • Docker
  • Terraform
  • Infrastructure as Code
Security
  • Cloud Security
  • Application Security
  • Secure SDLC
  • IAM
  • Vulnerability Management
  • Security Automation
DevSecOps

Experience integrating security into:

  • GitHub Actions / Azure DevOps / GitLab
  • CI/CD pipelines
  • Automated testing
  • Infrastructure deployment
  • Policy as Code
What Success Looks Like

After your first year you will have:

  • Established the foundations of Oneiro's security programme.
  • Embedded security into our engineering lifecycle.
  • Implemented a pragmatic set of security tools.
  • Reduced engineering friction through automation.
  • Improved visibility across our cloud estate.
  • Helped shape the long-term security strategy.
  • Become a trusted technical advisor to engineering teams.
  • Delivered meaningful improvements to the platform itself.
How We Work

We value engineers who:

  • Take ownership.
  • Automate repetitive work.
  • Prefer collaboration over gatekeeping.
  • Make pragmatic, risk-based decisions.
  • Continuously learn and improve.
  • Communicate clearly with both engineers and non-technical stakeholders.

You'll work closely with Engineering, Platform, Product and Leadership teams, helping everyone build secure systems without slowing innovation.

Why Join Oneiro?

You'll be joining at a pivotal stage in our growth.

Rather than inheriting years of technical debt and legacy processes, you'll help define how security is done across the organisation. You'll have genuine ownership, significant technical freedom and the opportunity to build a modern security function that engineering teams genuinely enjoy working with.

This is an opportunity to leave a lasting mark on both our platform and our culture.

Interview Process

1. 30 minute interview with hiring manager - Head of Security and Cloud Platforms.
2. Technical task.
3. Systems design / security architecture interview.
4. Meet the CTO.

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
