Job Description

As a Senior Cyber Security Analyst, you'll act as a technical authority within Security Operations, owning the design, development and continuous improvement of our detection and response capabilities.

You'll lead the response to major security incidents, drive threat-informed detection engineering, influence security architecture decisions, and work closely with colleagues across Security, Engineering and Platform teams to ensure ENSEK remains resilient against evolving threats.

This role combines hands-on technical expertise with leadership responsibilities, offering the opportunity to mentor junior analysts while contributing to strategic security initiatives across the business.


Key responsibilities:

  • Lead Security Incident Response by managing high-severity security incidents end-to-end, coordinating containment and recovery activities, conducting post-incident reviews, and acting as the senior technical lead during P1/P2 events.
  • Own Detection & Response Capability through the design, development and optimisation of SIEM detections, maintaining MITRE ATT&CK coverage, improving detection effectiveness, and identifying gaps across ENSEK's security monitoring landscape.
  • Drive Threat-Informed Security Operations by partnering with Threat & Vulnerability teams to operationalise threat intelligence, support vulnerability management activities, and ensure security operations remain aligned to ENSEK's evolving threat profile.
  • Enhance Security Automation & Operational Efficiency through the development of playbooks, automated response workflows, alert enrichment capabilities, and tool integrations that reduce analyst effort and improve response times.
  • Provide Security Leadership & Assurance by acting as the primary escalation point for Security Operations, mentoring analysts, supporting threat modelling activities, and providing security input into architectural and engineering decisions.
  • Deliver Security Reporting & Compliance Support by owning operational metrics and performance reporting, communicating risk to stakeholders, and contributing evidence and control monitoring activities supporting ISO 27001, SOC 2 and NIS2 compliance requirements.

Key outcomes:

  • Maintain an effective detection and response capability, continuously improving SIEM coverage, reducing false positives, and identifying gaps through MITRE ATT&CK aligned monitoring.
  • Lead the successful resolution of security incidents, ensuring timely containment, clear stakeholder communication, thorough post-incident reviews, and implementation of lessons learned.
  • Strengthen ENSEK's security posture by operationalising threat intelligence, supporting vulnerability remediation activities, and proactively identifying emerging risks.
  • Improve operational efficiency through the development of security automation, response playbooks and workflow enhancements that reduce manual effort and accelerate investigation and response times.
  • Increase security maturity across the organisation by providing security assurance to projects, supporting threat modelling activities, and embedding security monitoring requirements into new services and platforms.
  • Contribute to a high-performing Security Operations function by mentoring analysts, delivering meaningful operational reporting, and supporting compliance obligations including ISO 27001, SOC 2 and NIS2.

Experience required:

  • Proven experience operating within a Security Operations, Cyber Security Analyst, Security Engineer or Incident Response role, with responsibility for leading complex security investigations and major incident response activities.
  • Strong hands-on experience with SIEM platforms, including detection engineering, alert tuning, correlation rule development, coverage mapping, and the continuous improvement of monitoring capabilities.
  • Demonstrable experience leading security incidents from initial triage through to containment, recovery and post-incident review, including stakeholder management during high-severity events.
  • Practical experience applying the MITRE ATT&CK framework to detection engineering, threat hunting, investigations, threat modelling, or security control assessment.
  • Experience developing or supporting security automation and orchestration workflows, including the creation of playbooks, automated response actions, and integrations between security tools.
  • Experience working with cloud security technologies, endpoint detection and response (EDR/MDR) solutions, threat intelligence, and vulnerability management processes within a modern technology environment.
  • Strong communication skills with the ability to translate technical security risks, threats and vulnerabilities into clear, business-focused recommendations for both technical and non-technical stakeholders.
  • Experience mentoring, coaching or providing technical leadership to junior analysts, helping to develop team capability through knowledge sharing, documentation and continuous improvement initiatives.

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

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
