Job Description

We are seeking a hands-on Infrastructure & Security Engineer with deep expertise across security architecture, server, and network domains. Security is the core priority of this role. The successful candidate will take a leading part in strengthening and evolving the firm's security posture in response to an increasingly sophisticated threat landscape, including emerging risks associated with AI.

This is a technically demanding role that combines proactive security ownership with infrastructure delivery. The successful candidate will act as a security-first thinker across everything they touch, from day-to-day operations through to strategic infrastructure design, and will be expected to drive meaningful improvements to the firm's defensive capabilities.

This role is office-based and requires five days per week on-site presence.


Key Responsibilities

  • Lead the firm's security operations function, owning threat detection, incident response, and vulnerability management end-to-end
  • Monitor, triage, and respond to security events across the environment, including log analysis, anomaly detection, and threat hunting, with a strong awareness of modern and AI-enabled attack vectors
  • Own and drive security hardening across all infrastructure - servers, endpoints, network devices, and cloud-adjacent systems - ensuring consistent application of best practices and compliance with security policies
  • Design and implement secure infrastructure solutions, embedding security requirements from the outset rather than retrofitting them
  • Conduct regular vulnerability assessments and penetration testing exercises, prioritising and remediating findings in a timely manner
  • Manage and continuously improve security tooling, including SIEM, EDR, firewalls, IDS/IPS, and endpoint protection platforms
  • Act as the escalation point for security-related incidents across 2nd and 3rd line, providing expert guidance and driving resolution
  • Support and maintain network infrastructure including firewalls, switches, VPNs, and wireless systems (primarily Cisco-based), with a security lens on all configuration and change
  • Operate across Windows and Linux (Red Hat/CentOS) environments, ensuring both are maintained to a consistent security baseline
  • Collaborate with infrastructure and technology teams to embed security into project delivery and BAU processes
  • Develop and maintain security documentation including incident response playbooks, SOPs, architecture diagrams, and runbooks
  • Stay current with the evolving threat landscape, bringing proactive recommendations to improve the firm's security posture over time
  • Participate in an on-call rotation to support critical systems and respond to security incidents outside business hours

Requirements

  • Minimum 7+ years' experience in infrastructure, networking, and security roles
  • Strong hands-on experience with Windows Server and Linux (Red Hat/CentOS)
  • Solid networking knowledge, including TCP/IP, VLANs, VPNs, DNS, DHCP, with practical experience in Cisco environments
  • Demonstrated experience implementing and supporting security controls, including:
  • Patch management and system hardening
  • Endpoint protection and monitoring
  • Identity and access management
  • Good understanding of cyber security principles, including modern threat landscapes and evolving risks (e.g. automation and AI-driven attack vectors)
  • Experience with virtualisation (VMware) and enterprise storage (SAN/NAS)
  • Scripting or automation experience (e.g. PowerShell, Bash) is advantageous
  • Experience in financial services or regulated environments is preferred
  • Strong troubleshooting skills with a structured and analytical approach
  • Able to balance BAU responsibilities with project delivery effectively
  • A thoughtful and forward-looking mindset, with the ability to identify risks and propose improvements
  • Clear and confident communicator, able to engage with both technical and non-technical stakeholders
  • Self-motivated, accountable, and willing to take ownership of issues end-to-end
  • Collaborative and adaptable, with a practical and solutions-focused approach

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.
