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, OutSystems 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.
