Potential to convert to permanent
A purpose-led organisation based in East London is looking to appoint a Network Security Engineer on a 12-month fixed-term contract. This is an opportunity to join a business with a strong social impact, supporting the security and resilience of critical technology services.
This role would suit someone with a strong networking foundation and proven hands-on security experience, particularly across technical security assessments, operational monitoring, vulnerability triage, and security tooling.

The Role

* Develop and improve NOC and SOC procedures and support operational best practice
* Work closely with Security Analysts and wider teams on threat mitigation and incident response
* Support and train monitoring engineers within live operations environments
Key Requirements
* Previous experience in a Network Security Engineer, Security Operations, Technical Assurance, or similar role
* Strong background in networking, with a solid understanding of secure network design and operations

Package

* Opportunity to join an organisation with a genuine social purpose
* An East London-based role with a hybrid working environment
