Where you’ll work: Depending on the needs of your business area, we expect hub based people to be in the office at least once a week, and to go to OVO Connection events in-person.

Role context: Teamworking for the planet. Everything we do here spins around Plan Zero. So, naturally, the team you’ll be joining plays a gigantic role in making that happen. Here’s how: In this individual contributor role, you’ll help shape and deliver the strategic vision for OVO’s Digital Risk engineering programme. This includes developing automated, data-driven risk assessments, risk quantification and introducing accountability measures such as risk exceptions and capacity monitoring. You’ll work both within the immediate team and collaboratively across a wide range of teams throughout OVO.

This role in a nutshell: As a Principal Security Engineer (Risk Specialist) at OVO, you will be a key technical leader responsible for shaping the risk and security engineering strategies. This involves deep hands-on expertise, strategic thinking, guiding architectural decisions, embedding risk practices in code and at scale, and leading the way in solving complex and emerging risk challenges. You will ensure systems are designed with digital risk embedded from development through to runtime, set the direction for critical risk engineering initiatives, champion risk quantification and engineering excellence, and align the digital risk approach with OVO’s business goals. You will also be recognised as a trusted person in your field within OVO and the wider risk engineering community, particularly in challenging traditional technology risk approaches and building automated, AI-enabled digital risk management systems.

Your key outcomes will be:

• Define Security Strategy & Roadmaps: Lead the definition, refinement, and communication of technical strategies and multi-year roadmaps for key risk engineering capabilities or domains (e.g., zero trust architecture, automated risk discovery and management), aligning them with business objectives, compliance requirements, and the evolving threat landscape.
• Architectural Leadership & Governance: Develop, maintain, and govern secure reference architectures, critical design patterns, and enforceable technical standards. Provide expert architectural consultation and design reviews for the most complex, critical, or cross-functional projects and platforms. Steer technology choices through an expert security lens.
• Solve Top-Tier Risk and Resilience Problems: Challenge the traditional security and tech risk assessment and modelling approach. Tackle the most challenging, ambiguous, and impactful technical risk problems facing the organisation, often requiring deep research, novel solution design, and cross-functional collaboration to resolve systemic issues. Prototype, evaluate, and champion innovative security and risk solutions.
• Lead High-Impact Risk Initiatives: Build an automated and AI-enabled digital risk management system and use risk quantification to shape decision-making and guide us in prioritising risk responses and control design. Drive the technical vision, architecture, and strategy for complex, organisation-wide risk engineering programmes and transformations (e.g., implementing advanced data protection assessments and controls, maturing risk response capabilities, comprehensive attack surface reduction).
• Organisational Risk Assessment & Strategic Guidance: Serve as a definitive authority on complex digital risk assessments, particularly those with strategic implications. Analyse systemic risks, synthesize complex information, and provide clear, actionable recommendations and strategic security guidance to senior leadership (VP/C-level) and technology executives.
• Champion Advanced Secure Development & Testing: Drive the continuous advancement, adoption, and measurement of mature Secure Development Lifecycle (SDL) methodologies (DevSecOps) and sophisticated security testing strategies (e.g., threat-led penetration testing, fuzzing at scale) across the entire engineering organisation.
• Influence & Strategic Collaboration: Enable OVO to lean into smart risks by building a platform that promotes scalable risk identification, evaluation, impact analysis, risk quantification and risk transparency to increase confidence in managing digital risk. Influence product management, platform engineering, and business unit roadmaps to proactively incorporate necessary policies and controls as code and address significant technical debt. Build strong, collaborative relationships with senior leaders across engineering, product, legal, and other business functions.
• Mentor Senior Technical Staff & Elevate Practice: Mentor Lead and Senior engineers across OVO in advanced security disciplines, strategic thinking, architecture, and technical leadership. Contribute to internal communities of practice, develop training for senior staff, and elevate the overall security engineering practice at OVO.
• Community of Practice: Drive the Community of Practice (CoP) for your role by actively leading, cultivating and growing the CoP as a result of your industry engagement and thought leadership. Create content, engage in knowledge exchange / cross-pollination to further your craft. Mentor and coach individuals in the role-based competencies associated with a CoP. Input to upskilling and learning pathways based on the CoP that will aid individuals' career progression.
