Our purpose is underpinned by five Starling values: Listen, Keep It Simple, Do The Right Thing, Own It, and Aim For Greatness.

About the Role

We’re seeking a passionate and skilled Detection Engineer and Threat Hunter to join our growing Security Operations team, and proactively defend Starling Bank against emerging threats.

Reporting to the Information Security Lead - Detection, the analyst’s primary responsibility will be to proactively identify and defend against potential threats to the bank. You will achieve this by developing, tuning, and maintaining detection rules, conducting intelligence-driven threat hunts, and participating in collaborative defence improvement activities like Purple Teaming to identify and mitigate risks before they impact the bank.

Please note, there is an on-call element to this role.

What you’ll get to do

• Detection Engineering - Design, build, test, and maintain high-fidelity detection rules and analytics in our SIEM and other security platforms.
• Proactive Threat Hunting - Formulate hypotheses and hunt for undetected attacker TTPs across our cloud (AWS, GCP, Azure), SaaS, and endpoint environments.
• Purple Team - Collaborate with our Adversarial Simulation team in Purple Team exercises to test, validate, and improve detection logic and response.
• Incident Response SME support - Act as a Subject Matter Expert during security incidents, providing deep technical analysis and aiding remediation.
• Threat Intelligence integration - Integrate and operationalise threat intelligence to inform detection strategies and hunting projects.
• Collaboration - Work closely with the wider Security Operations team, and other stakeholders to uplift Starling's security posture and improve detective controls.
• Documentation - Maintain clear documentation for detection rules, hunting playbooks, and processes.

• 5+ years in a technical security role, such as detection engineering, threat hunting, incident response, or threat intelligence.
• Attacker Knowledge: Practical experience analysing attacker behavior, with a strong understanding and application of threat analysis models like MITRE ATT&CK to prioritize and enhance detective controls.
• SIEM Expertise: Hands-on experience with SIEM platforms (e.g., Splunk, Google SecOps, Elastic, Sentinel) for rule/query creation and analytics.
• Threat Hunting: Experience conducting proactive threat hunts, defining hypotheses, and developing hunting methodologies.
• Cloud Security: Solid knowledge of security risks and detection strategies for AWS, GCP, Azure.
• EDR Proficiency: Experience with EDR tools (e.g., Crowdstrike, SentinelOne, Cortex XDR).
• Core Technical Skills: Good understanding of OS internals (macOS, Linux, Windows) and network security principles.
• Key Attributes: Excellent analytical, problem-solving, and communication skills. Self-starter, able to lead projects, and highly collaborative.
• Growth Mindset: Eagerness to learn and apply knowledge to new security challenges.

Preferred

• Experience with at least one programming or scripting language (e.g., Python, Go, Bash) for security automation or analysis.
• Experience with container security monitoring (Docker, Kubernetes).
• Experience with SOAR platforms.
• Knowledge of digital forensics and incident response procedures.
• Understanding of malware analysis techniques.
