Cyber Security Architect – Threat Modelling (Contract)
Location: UK-based, with travel to Bristol, Manchester, North West England and London for on-site work
Working Pattern: Hybrid with travel to client sites as required
Type: Contract
Rate: Up to £700 per day, Outside IR35
Clearance: UK National with active SC Clearance — this is a mandatory requirement
Company: Tektora, supporting an established Technology Consultancy
Tektora are supporting an established Technology Consultancy who are looking to speak with SC Cleared Cyber Security Architects for a contract opportunity leading threat modelling and secure design across complex client environments.
Please note: active SC Clearance is essential for this role. Applications cannot be considered without it.
This role would suit an experienced security architect who runs threat modelling as a discipline rather than an occasional task, is comfortable acting as the design authority on complex systems, and is looking for a well-defined outside IR35 engagement where the threat modelling work is the centre of the role rather than a sideline.
The Role
You Will Be Involved In
- Leading threat modelling across complex systems, cloud platforms and enterprise architectures
- Facilitating threat modelling workshops with architects, engineers and business stakeholders
- Performing system decomposition, trust boundary analysis and attack path identification
- Acting as design authority on secure solution designs and architecture reviews
- Producing reference architectures, secure design patterns and reusable threat models
- Conducting security risk assessments and setting proportionate, risk-based mitigations
- Translating threat models into security monitoring requirements and detection use cases
- Reviewing and assuring designs produced by other architects and delivery teams
- Supporting and upskilling internal teams so threat modelling continues after the engagement
- Presenting findings, risks and design decisions to technical and senior stakeholders

- Experience operating as a design authority or senior technical escalation point on security designs
- Demonstrable experience conducting security risk assessments and producing risk-based recommendations
- Experience defining security monitoring requirements and detection use cases from threat models
