Security Architect

Company Description

Version 1 has celebrated 30 years in business and continues to be trusted by global brands to deliver technology and transformation solutions that drive customer success. Our deep expertise enables our customers to navigate the rapidly evolving technology landscape. We foster strong partnerships with global technology leaders including Microsoft, AWS, Oracle, Red Hat, Out Systems and Snowflake, ensuring that our customers are provided with the highest quality solutions and services.

As a Security Architect, you’ll partner with government, financial services and private sector clients to design security solutions that address their most complex digital risks. You’ll translate threat landscapes, compliance obligations and business constraints into practical security architectures, working across the full engagement lifecycle, from threat modelling to security options analysis to facilitating design sessions with delivery teams and presenting recommendations to architecture review boards and senior stakeholders.

Whether that’s defining a zero‑trust approach for a government department, designing security controls for a bank’s cloud migration or guiding development teams through secure‑by‑design decisions, you’ll bring both depth and pragmatism. Your background in cloud security, application security and public sector compliance means clients can trust your advice on what works in enterprise environments.

You’ll join our central architecture practice alongside experienced Technology Principals and Solution Architects. Security in delivery teams is often underserved; your role is to change that, not through gates and sign‑offs, but by embedding security thinking early and keeping it there. This includes guiding and upskilling delivery teams on secure‑by‑design practices, helping engineers and product managers build security literacy without slowing down delivery.

You’ll have designed and validated security architectures for enterprise‑scale programmes across cloud platforms, application security, identity and access management and system integration. You can point to successful outcomes and take clear ownership of the security design decisions that got there.

Cloud and application security: experience securing workloads on AWS and/or Azure, including network segmentation, IAM, encryption, secrets management and security monitoring. You understand App Sec practices including secure SDLC, SAST/DAST tooling, API security and container security in agile delivery contexts.

Experience directly working with clients and senior stakeholders to assess risk, facilitate threat modelling and build consensus around security approaches. You communicate clearly with both technical teams and non‑technical leadership.

and public sector compliance: experience working within  digital standards, GDS service assessments, NCSC guidance and UK government security classifications (Official, Secret). Familiarity with DSP Toolkit or equivalent assurance frameworks.

Financial services security: experience designing controls for regulated financial environments, including FCA/PRA expectations, PCI‑DSS and secure integration patterns for core banking or payment systems.

Security frameworks and standards: working knowledge of NIST CSF, ISO 27001, CIS Controls or SABSA. Holds or is working towards CISSP, CISM, CCSP or equivalent.
