- As a senior security engineer you will pioneer an innovative and inclusive security culture, inspire with compelling security solutions and land secure defaults and designs in data and cloud native engineering teams’ code, CI/CD and infrastructure
- You will personally excel at implementing reliable tools to prevent, mitigate or automatically remediate misconfigurations and vulnerabilities. You will champion operational excellence across all OVO-built and accessed applications and infrastructure
- Minimise Security Risk Exposure: Proactively identify, assess, and drive the mitigation of complex security risks within key products and systems through continuous attack, exposure and controls monitoring, expert assessment, threat modelling, and leading remediation efforts
- Strengthen Secure Foundations: Champion and embed robust security architecture principles, secure development lifecycle (SDL) practices, and practical standards within development teams to build security in from the start
- Enhance Security Operations & Team Capability: Optimise security tooling and processes within your domain for effectiveness and efficiency, while accelerating the development of junior engineers through active mentorship and guidance
- Develop & Maintain Security Standards: Define, document, socialise, and maintain specific security standards, baselines, and procedures tailored to your assigned products or teams. Ensure these align with broader organisational policies while providing practical, actionable tools and guardrails for developers and engineers
- Lead Risk Assessments & Threat Modelling: Independently plan and conduct in-depth security risk assessments (evaluating likelihood and impact) and perform routine, detailed threat modelling (including attack path analysis) for key projects, features, and applications. Analyse complex findings, prioritise risks effectively, and architect practical, proportionate mitigation strategies
- Manage & Optimise Security Tooling: Take full ownership of configuring, operating, tuning, and maintaining relevant security tools (e.g., SAST, DAST, IAST, SCA, vulnerability scanners, CNAPP, CADR and WAF policies) within your domain. Focus on integrating tools seamlessly into CI/CD pipelines, automating processes, minimising false positives, and building data flows that ensure findings lead to actionable remediation.

- Embed Secure Architecture: Serve as a security authority during design phases. Proactively review proposed architectures, features, and system designs, applying security principles and best practices (e.g., defense-in-depth, least privilege, secure-by-default). Recommend secure design patterns, technologies, and configurations, collaborating closely with development and platform teams to embed security from the start
- Oversee & Interpret Security Testing: Plan, scope, conduct, or commission comprehensive security tests (e.g., penetration tests, vulnerability assessments, code reviews) for your projects and pipelines. Critically analyse and interpret complex results from various testing sources, validate findings rigorously, and translate technical risks into business impact. Guide junior engineers effectively through the testing process
- Mentor Junior Engineers: Actively mentor associate and mid-level security engineers. Provide technical guidance on security concepts and tools, review their work (e.g., assessment reports, proposed controls), share knowledge and experience, and support their professional development within the team
- Community of Practice: Contribute to the security engineering Community of Practice (CoP) by leading discussions, sharing practices, offering firsthand experience to the wider community, engaging in knowledge exchange / cross-pollination to further your craft. Create content and and individually contribute to the stated successful outcomes for this CoP
