Job Details

We are working with a client who is a global leader in consulting, technology services, and digital transformation, committed to delivering positive change through technology and human collaboration. They have a Cybersecurity Sciences & Analytics (CSA) team that is currently a -$50m and -150 headcount function, bringing together expertise across cybersecurity, data science, AI, software and cloud engineering, governance, and programme management.

This Technical Solution Architect role is a hands-on architecture and solution design specialist within the CSA Strategy and Governance team. They shape and assure end-to-end technical designs that enable CSA's cyber analytics and engineering outcomes. They define and maintain key architecture artefacts (HLDs/LLDs, reference architectures, patterns, and ADRs). They also drive technology evaluation and standardisation across an open-source, petabyte-scale data platform. They own solution designs for custom cybersecurity applications, from requirements through to production support. Partnering with engineering, platform, and central architecture/governance teams, they run design and governance forums and influence without authority. They'll bring genuine cybersecurity expertise-threat modelling, security controls, identity and access, encryption, logging, and secure SDLC-so CSA's platforms and products can be trusted in production and stand up to regulatory scrutiny. They balance target architecture with delivery realities, collaborate across geographies, and contribute hands-on when needed, including coding. The ideal candidate will possess a strong technical background, an eagerness to learn, a keen interest in Cybersecurity, the ability to work collaboratively in a fast-paced environment, and an aptitude for picking up new tools and techniques on the job, building on existing skillsets as a foundation.

In this role you will be defining and maintaining architecture artefacts, including HLDs/LLDs, reference architectures, patterns, ADRs (Architecture Decision Records), and reusable templates. Contributing to the design and evolution of a petabyte-scale data platform built on open-source technologies. Evaluate technologies and drive standardisation: assess OSS components and vendors, run PoCs, document trade-offs, and promote reusable patterns to reduce fragmentation. Own the end-to-end solution design for custom-built applications that support our client's cybersecurity ambitions. Provide architecture and design input to software engineering and platform teams to support implementation and delivery. Partner with central architecture and governance teams to ensure solutions align with the client's controls, policies, standards, and guardrails. Help ensure solutions remain compliant, operationally supportable, and within agreed cost boundaries.

In order to apply for this role, you must have demonstrable experience designing, deploying, and operating big data platforms at scale. You will have hands-on experience with OSS data ecosystems (e.g., Spark, Trino, Airflow, Apache Superset, and similar technologies). You will have knowledge of cloud platforms and traditional on-premise hosting; hands-on experience with Azure, AWS and/or GCP is beneficial. You will also have proven security architecture expertise, including: Threat modelling and secure-by-design practices. IAM (RBAC/ABAC), privileged access concepts, and service-to-service authentication. Encryption in transit/at rest, key management, secrets management. Secure logging/telemetry, auditability, and evidence-driven control assurance. Secure SDLC, vulnerability management, and dependency/supply-chain risk controls. Proven experience delivering end-to-end solution designs, from requirements through to production operations and support.

Please be clear that only candidates that meet the above criteria with the right to work and that are resident in the UK will be considered. No sponsorship is available. This role will involve hybrid working here in the UK at a site based in Sheffield in South Yorkshire - expected on site 3 days per week and 2 from home.
