Job Description
We help UK public sector organisations build and run digital services that are secure, trustworthy, and resilient. As a Senior Security Engineer in our Cyber practice, you will need to be able to take end-to-end ownership of securing the systems we build; embedding security into delivery pipelines and building the tooling and automation that keep complex government services safe by default.
We're looking for a Senior Security Engineer- Monitoring & Detection who can build and tune detection logic in a live SOC, and own the pipelines that feed it. You'll work hands-on across SIEM/detection and log ingestion/normalisation, and translate technical risk into decisions for government stakeholders and system owners. This is a delivery role: security assurance should speed decisions up, not slow them down.
Key Responsibilities
Detection Engineering
- Build & tune: detection rules across Splunk (SPL), YARA and EDR platforms.
- Coverage & quality: map detections to MITRE ATT&CK; track signal-to-noise and false-positive rates to keep alerting high-fidelity.
- Validation: test new/updated rules via replay and load testing; run red-team scenarios for critical rules.
- Feedback loops: work with L1–L3 analysts so detections stay grounded in operational reality.
- Pipelines: manage log ingestion on Cribl — routing, filtering, normalisation, and enrichment at the edge.
- Optimisation: reduce volume via deduplication, trimming, and NetFlow summarisation; manage streaming/storage (Kinesis, S3, Amazon Security Lake).
- Standards: apply hot/warm/cold data tiering; normalise into OCSF; enforce encryption and least-privilege access.

We believe we can use tech to make public services better. We also believe this can happen best when our own team represents the society that actually uses the services we work on. We’re collectively continuing to grow a culture that is happy, healthy, safe and inspiring for people of all backgrounds and experiences, so we encourage people from underrepresented groups to apply for roles with us.
When you apply, we’ll put you in touch with a member of our talent team who can help with any needs or adjustments we may need to make to help with your application. We’ve put together this blog as a resource to share more about reasonable adjustments and some examples of what this could include. We also welcome any feedback on how we can improve the experience for future candidates.
Working hours
Our standard hours are Monday to Friday, but the nature of this role means some work outside normal hours may be required, for example during release and change windows, planned maintenance, or to align with client operating hours. This is occasional rather than routine, and we'll always give as much notice as we can and agree it with you in advance wherever possible.
