Cybersec Data Platform Solution Engineer

Role Title: Cybersec Sciences & Analytics_OpenSource Data Platform Solution Engineer
Duration: contract to run until 10/08/2027
Location: Sheffield. Hybrid, 3 days per week onsite
Rate: up to £533.60 p/d Umbrella inside IR35

Role Purpose / Summary

Cybersecurity Sciences & Analytics (CSA) is a ~$50m and ~150 headcount function, bringing together expertise across cybersecurity, data science, AI, software and cloud engineering, governance, and programme management to:

• Deliver cyber analytics capabilities that measurably improve cyber prevention, control effectiveness, and the resilience of operations across the cyber lifecycle
• Engineer, automate, and continuously enhance cyber detection and response capabilities to enable effective, resilient, and scalable security operations
• Provide trusted Cyber risk, control, and regulatory insights that inform executive decision-making and investment prioritization
• Ensure cyber products, data, and bank-wide AI use cases comply with cyber risk appetite, regulatory requirements, and data standards, through effective data and AI governance
• Evolve Cyber analytics platforms, products, and engineering practices through a controlled maturity roadmap, to improve platform and operational resilience, efficiency, and sustainability without increasing risk

This Technical Solution Engineer is a hands‑on architecture and solution design specialist in CSA's 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.

Principal Responsibilities

• Define and maintain architecture artefacts, including HLDs/LLDs, reference architectures, patterns, ADRs (Architecture Decision Records), and reusable templates.
• Contribute 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 the Bank's cybersecurity ambition.
• 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 Bank's controls, policies, standards, and guardrails.
• Help ensure solutions remain compliant, operationally supportable, and within agreed cost boundaries.
• Person requirements
• Strong team player, able to collaborate effectively with colleagues across geographies, time zones, and cultures.
• Excellent written and verbal communication skills, with the ability to explain complex technical topics clearly.
• Able to influence without authority; confident facilitating design workshops and governance forums.
• Strong prioritisation and pragmatic decision-making, balancing target architecture with delivery realities.
• Comfortable designing solutions end-to-end, while also able to roll up sleeves and contribute hands‑on (including coding where needed).
• Skills and knowledge
• Demonstrable experience designing, deploying, and operating big data platforms at scale.
• Hands‑on experience with OSS data ecosystems (e.g., Spark, Trino, Airflow, Apache Superset, and similar technologies).
• Knowledge of cloud platforms and traditional on‑premise hosting; hands‑on experience with Azure, AWS and/or GCP is beneficial.
• 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.
