Lead Technical Recruiter - Architecture, Delivery, Product, and IT Ops

As a Security Architect (DSA), you’ll help design and maintain secure systems across the Home Office. Working alongside Lead and Principal Security Architects, you’ll apply best-practice frameworks and risk-based controls to ensure our services are resilient and compliant. You’ll collaborate with engineers, DevOps teams, and stakeholders to embed security into every stage of development.

Your role will involve assessing vulnerabilities, advising on secure design, and translating complex threats into clear, actionable guidance. Whether recommending new tools, leading penetration tests, or shaping policy, your work will help protect sensitive data and support the delivery of secure, user-focused services.

Data Services and Analytics (DSA) is the Home Office’s centre of data expertise, bringing together professionals from diverse backgrounds to deliver impactful insights and secure digital services. We’re committed to continuous learning, inclusion, and the wellbeing of our people, all while supporting the department’s vital public mission.

What will you do?

Design secure architectures and review existing systems, ensuring alignment with industry frameworks (e.g., ISO 27001, NCSC).
Collaborate with Lead/Principal Security Architects to implement cohesive security solutions, bridging technical teams and senior stakeholders.
Advise multidisciplinary groups (Engineering, DevOps, Architecture) on risk assessments, recommending proportionate controls for cloud, on-premise, and hybrid environments.
Oversee or assist in penetration testing and security assessments, verifying vulnerabilities are identified and tracked to resolution.
Communicate complex security concepts clearly, helping both technical and non-technical colleagues to understand risks and adopt best practices.
Maintain awareness of evolving threats, tooling, and methodologies, adapting security strategies to protect critical systems and data.
Enforce consistent security standards, documenting designs, updating policies, and applying recognized architecture approaches (e.g., SABSA, TOGAF).

What will you bring?

Secure system design – applying best-practice patterns (e.g., zero trust, defense in depth) to manage risk while meeting user requirements.
Threat and risk assessment – using frameworks like ISO 27001, COBIT, or NIST to identify vulnerabilities, prioritize fixes, and justify decisions.
Technical expertise – applying security concepts at a technical level, working with security tools, network security infrastructure technologies, and Information Security Management frameworks (e.g. ISO 27000, CoBIT, NIST).
Penetration testing & remediation – planning or scoping tests, interpreting findings, and guiding improvements to maintain system integrity.
Effective communication – translating security concepts for diverse audiences, influencing decisions, and promoting secure practices.
Collaboration – partnering with architects and DevOps teams to ensure alignment between security goals and business objectives.
