Job Description

The Cyber Defence Operations function protects AJ Bell against external adversaries and internal risks through four specialist capabilities: Security Monitoring & Detection Engineering, Cyber Threat Intelligence, Cyber Threat Exposure Management and Insider Risk Management. Together, these capabilities combine detection, intelligence, exposure management and insider risk to safeguard AJ Bell's customers, data, critical services and the trust placed in the firm.

Security Monitoring & Detection Engineering provides an integrated monitoring, detection and response capability, combining internal technical expertise with 24x7 support from the Managed Security Service Provider.

The Security Monitoring & Detection Engineering Lead is the principal technical authority for Security Monitoring & Detection Engineering capability, accountable for the effectiveness of security monitoring, detection engineering, technical investigation and incident response. This is a hands-on technical role responsible for the architecture, engineering and operational performance of Microsoft Sentinel and the wider security monitoring estate.

The role would particularly suit an experienced detection engineering, security operations, red-team, purple-team or offensive-security leader who can translate real-world adversary behaviour into effective monitoring, detection and response. The role leads complex investigations and technical incident response, ensures the internal team and MSSP operate as one capability, and drives measurable improvements that reduce the potential for customer, operational, financial and regulatory harm.

This role participates in the Cyber Defence Operations on-call rota, providing senior technical leadership during significant out-of-hours security events and declared cyber incidents.


Key Responsibilities

  • Own the technical direction, quality and delivery performance of Security Monitoring & Detection Engineering, translating CDO priorities into a clear roadmap for monitoring, detection, investigation and response.
  • Lead the architecture, engineering and continued development of our SIEM solution, ensuring the SIEM remains resilient, scalable, cost-effective and aligned with AJ Bell's technology estate and threat profile.
  • Define and govern the onboarding of security telemetry across on-premises, Microsoft Azure, AWS and third-party services, ensuring log sources address genuine visibility gaps and provide reliable value for detection and investigation.
  • Own the detection engineering lifecycle across requirements, design, testing, deployment, tuning, performance assessment and retirement, supported by version control, peer review and controlled release practices.
  • Lead the development of analytics rules, hunting queries, workbooks and automated investigation and response workflows.
  • Own the operational effectiveness of security solutions managed by CDO ensuring configurations, integrations, detections and workflows deliver measurable security outcomes.
  • Drive threat-informed defence with Cyber Threat Intelligence and Cyber Threat Exposure Management, translating relevant threat actors, campaigns, TTPs, IOCs, critical vulnerabilities and attack paths into detections, targeted threat hunts and automated defensive actions.
  • Maintain an evidence-based view of service performance through agreed KPIs, KRIs and operational MI, identifying material variations, recurring failure points and capacity constraints, and driving corrective actions through to a measurable outcome.
  • Act as the senior technical escalation point for complex, ambiguous and high-severity security events, leading investigations through scoping, attack reconstruction, business-impact assessment, containment and resolution.
  • Experience investigating malicious code, identity compromise, business email compromise, fraud-related intrusion, data exfiltration, cloud compromise or third-party intrusion.
  • Lead technical response within CIRT during declared cyber incidents, coordinating the internal team, MSSP and relevant technology functions in accordance with the firm's incident-management processes to contain threats and reduce business impact.
  • Build and improve investigation and response playbooks for priority threat scenarios, and lead tabletop, purple-team and practical exercises that test detection coverage, technical readiness and coordination with relevant business functions.
  • Operate the internal team and MSSP as one integrated monitoring and response capability, setting clear expectations for investigation quality, escalation consistency and response effectiveness, and addressing service issues before they affect security outcomes.
  • Maintain an evidence-based view of alert demand, detection quality, MTTA, MTTR, investigation outcomes, service capacity and recurring failure points, using these measures to prioritise and demonstrate improvement.
  • Lead service reviews with key security vendors and providers, assessing delivery against expected outcomes and driving actions that maximise the contribution of existing investment to CDO's Detect, Defend and Respond objectives.
  • Identify and deliver appropriate uses of automation and AI across detection engineering, enrichment, investigation and response, measuring the resulting improvement in quality, speed, consistency or coverage.
  • Develop Senior Analysts and junior team members through technical leadership, investigation review, practical training and structured knowledge transfer, creating credible succession within the function.
  • Report functional performance, incident readiness, monitoring coverage, material risks and capability constraints to the Head of Cyber Defence Operations, providing clear recommendations and action plans.

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.

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.

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.
