About the role
As a Senior Cyber Security Engineer at Rowden, you’ll collaborate closely with the wider engineering team to design, implement, and maintain secure systems and infrastructure. You will be embedded within a delivery team(s) and work closely with the Technical Security Lead and external partners to assess risks, define security requirements, and ensure technical solutions are pragmatic, proportionate, and aligned with both business and customer needs.
Your focus will span both strategic and tactical aspects of security engineering. At a strategic level, you’ll contribute to high-level design and planning across areas such as secure network architecture, identity management, and cloud security. At a tactical level, you’ll be hands-on with implementation, working directly with systems, tools, and configurations to apply and validate security controls, troubleshoot issues, and support secure delivery. You’ll collaborate with the wider engineering community to ensure agreed controls are effectively embedded, and that all systems are resilient, compliant, and aligned with current security standards.
The ideal candidate will bring knowledge of threat modelling, secure system design, and compliance frameworks including NIST, ISO 27001, and DefStan 05-139. We understand that even experienced professionals may not have expertise across every aspect of the role. If you bring relevant experience, sound technical judgement, and a passion for delivering secure solutions, we encourage you to apply.
This role requires a minimum of 3 days per week on-site at our Bristol HQ with occasional travel to customer sites.
Candidates must be eligible for SC clearance. Due to the nature of this role and the sensitivity of the work involved, applications are restricted to sole UK nationals.

- Participating in security risk assessments, threat modelling, and vulnerability management for cloud, software, and far-edge deployments.
- Contributing to the security accreditation process, preparing evidence, managing asset registers and supporting audits as required.
- Assisting in the continuous improvement of security processes, incident response, and compliance monitoring.
- Engaging with supply chain partners to verify and assure security requirements throughout the capability lifecycle.
- Providing technical advice and hands-on support to engineering teams, acting as a security champion within agile delivery teams.
