European number one in cybersecurity and a leader in cloud, Atos Group is committed to a secure and decarbonized future and provides tailored AI-powered, end-to-end solutions for all industries.

About Role:

Contribution / Impact:

This role offers the opportunity to contribute security outcomes of one of the UK’s largest and most high-profile infrastructure programmes. The successful candidate will play a critical role in ensuring secure-by-design delivery across a programme of works with significant national importance.

Bigger Challenge / Scope / Responsibilities:

This is an opportunity to step into a role with greater scope, responsibility, and impact. You will lead security across complex, multi-stakeholder programmes, addressing architectural and operational challenges that directly influence business and security outcomes.

Interesting Brand or Reputation:

Join Atos and help secure some of the UK's most critical infrastructure. The scale, complexity, and visibility of these programmes will enhance your professional reputation, strengthen your personal brand, and position you as a trusted security leader.

Influence:

Hybrid:

Initially, the role will require a presence at the client's Birmingham city centre offices for three days per week. As familiarity with the environment increases and key deliverables are achieved, the on-site requirement is expected to reduce accordingly.

Role Purpose:

The Security Architect is responsible for ensuring that security is embedded into business and technology solutions by design.

Support risk management processes and risk-based decision making.

Governance & Assurance

Act as a security authority within architecture review boards and governance forums.

Define and maintain security standards, controls and architecture principles.

Review and approve architecture exceptions where appropriate.

Ensure compliance with relevant regulations, contractual obligations and industry frameworks.

Security Strategy & Roadmaps

Support the development and maintenance of security strategy and roadmaps.

Identify opportunities to improve security capability, resilience and operational effectiveness.

Contribute to long-term security transformation initiatives.

Stakeholder Engagement

Collaborate with business leaders, delivery teams, operational teams, suppliers and customers.

Translate complex technical security concepts into business-focused recommendations.

Act as a trusted advisor on security architecture and cyber risk matters.

Incident & Operational Support

Provide architectural support during security incidents and major service disruptions.

Support root cause analysis and remediation activities.

Assist with security tooling evaluations and strategic technology decisions.

Mentoring & Leadership

Lead and mentor architects, engineers and technical specialists.

Promote security awareness and best practice across teams.
