Security Architect

Please note - this role will be remote or hybrid working, subject to the successful applicant's location in line with company policy

About the role

We are looking for a Security Architect to join our central Architecture & Design practice at NEC Software Solutions.

This role sits at the heart of how we design, assure, and operate secure systems and services across both internal platforms and customer‑facing solutions. You will work closely with architects, engineering teams, and the wider cyber security function to ensure security is embedded by design.

This is a hands‑on, design‑led role. You will be involved in real delivery, real assurance, and real decision‑making, from early threat modelling and risk assessment through to architecture assurance, accreditation support, and implementation guidance.

The role is well suited to someone who enjoys balancing pragmatic security design with governance, assurance, and stakeholder engagement in complex, regulated environments.

What you’ll be doing

• Producing security architecture designs for internal systems and customer solutions, aligned with the overarching architecture framework.
• Conducting threat modelling and risk assessments to identify and manage security risks in applications, platforms, and services.
• Producing security assurance documentation to support internal governance, customer assurance, and formal accreditation activities.
• Working closely with Technical Architects and Enterprise Architects to ensure solutions are secure by default and proportionate to risk.
• Engaging with the wider cyber security team to assess the impact of emerging threats and vulnerabilities (CVEs) and advise on appropriate remediation.
• Supporting delivery teams with security advice and guidance, including hands‑on engagement where needed.
• Presenting security designs and risk positions to the Technical Assurance Board and supporting assurance decision‑making.
• Contributing to bids and sales activities by providing security architecture input and responses to security questionnaires.
• Supporting the evaluation and controlled adoption of new security technologies.
• Continuously developing your skills and knowledge in line with evolving threats, technologies, and standards.

Why join us?

• Work on meaningful systems supporting critical public‑sector services.
• Be part of a collaborative architecture practice spanning security, technical, and enterprise domains.
• Balance hands‑on security design with governance and assurance.
• Grow your career in an environment that values pragmatism, professionalism, and continuous improvement.

About you

You’re likely to be:

• A Security Architect or senior security engineer with strong design experience, or
• A technical specialist ready to step into a broader architecture and assurance role.

You’ll bring:

• Practical experience designing and assuring secure systems.
• Strong understanding of security principles, non‑functional requirements, and risk management.
• Confidence engaging with stakeholders across engineering, architecture, and governance.
• Experience working in regulated or public‑sector environments is a plus.

Familiarity with standards such as ISO 27001, NCSC Cyber Essentials, NIST, or CIS is desirable, but we value sound judgement and practical experience over certification alone.
