Security Architect

Job Description

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, security options analysis, through 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 under‑served; your role is to change that, not through gates and sign‑offs, but by embedding security thinking early and keeping it there. That includes guiding and upskilling delivery teams on secure‑by‑design practices, helping engineers and product managers build security literacy without slowing down delivery.

• Designed and validated security architectures for enterprise‑scale programmes across cloud platforms, application security, identity and access management, and system integration, producing demonstrable outcomes and owning the security design decisions.
• Experienced securing workloads on AWS and/or Azure, including network segmentation, IAM, encryption, secrets management, and security monitoring.
• Knowledge of App Sec practices such as secure SDLC, SAST/DAST tooling, API security, and container security within agile delivery contexts.
• Experience working directly with clients and senior stakeholders to assess risk, facilitate threat modelling, and build consensus around security approaches; able to communicate clearly with both technical teams and non‑technical leadership.

• and public sector compliance experience (GDS service assessments, NCSC guidance, UK government security classifications).
• Financial services security experience (FCA/PRA expectations, PCI‑DSS, secure integration patterns for core banking or payment systems).
• Working knowledge of NIST CSF, ISO 27001, CIS Controls, or SABSA; holding or working towards CISSP, CISM, CCSP, or equivalent.
• GenAI security experience (assessing and mitigating risks in AI/ML solution architectures, data exposure, prompt injection, model supply chain, output integrity).

• Quarterly Performance‑Related Profit Share Scheme – employees benefit from a share of the company’s profits.
• Strong career progression and mentorship coaching through Strength in Balance & Leadership schemes and a dedicated quarterly Pathways Career Development programme.
• Flexible/remote working with generous flexibility to support work‑life balance.

• Employee wellbeing schemes: gym discounts, bike‑to‑work, fitness classes, mindfulness workshops, employee assistance programme, generous holiday allowance, enhanced maternity/paternity leave, marriage/civil partnership leave, and special leave policies.
• Educational assistance and incentives for certifications and accreditations (AWS, Microsoft, Oracle, Red Hat).
• Reward schemes including Annual Excellence Awards and a 'Call‑Out' platform.
