Additionally, reports from June 2025 indicated that OVO is in exploratory merger talks with Iberdrola, the owner of Scottish Power, which could further reshape the competitive landscape of the UK energy market (source: wikipedia.org).

Job Description

At OVO, we are on a mission to solve one of humanity's biggest challenges, the climate crisis. And we know it takes all of us to change the world. That's why we need diverse people from all abilities, gender identities, ethnicities, ages, sexual orientations, life experiences and backgrounds to join us.

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:

We're hiring creators and challengers who deliver high-impact, well-engineered solutions. Every role we're hiring puts people at the heart of our security strategy and uses technology and operational processes to build a resilient and performant business. The Path to Zero is paved with secure technology!

This role in a nutshell

As a Senior Security Engineer (Data), you will work closely with fellow security engineers to design, build, and deploy data solutions that drive organisation-wide security value. To do this, you will build and maintain ETL/ELT pipelines and data models within data warehouses. An example pipeline being ingesting data from multiple security and technology observability tools to gather, analyse, synthesise, and develop visualisations and reporting in service of continuous improvement of security controls.

Your solutions will enable cyber defence, attack surface and security controls engineers to proactively identify hidden problems and patterns in data and use these insights to amplify weaknesses and drive improvements to coding hygiene and system architecture. This is a great opportunity for someone who is motivated to use data to drive security improvements, and best practices across a business with wide-ranging impact, and loves working in collaborative, and supportive environments.

Your key outcomes will be

  • Help architect, design, and deploy new features, and functionality in a unified OVO security data platform to enable security engineers to optimise and automate cyber defence, attack surface and security controls assurance processes.
  • Stay up-to-date with the latest security data and AI trends, tools, and technologies to ensure the team's technical approach is innovative.
  • Foster an inclusive team environment where everyone feels valued and excited to contribute.
  • Communicate optimally with collaborators to explain concepts and drive informed decision making.

Within your first 3 months month you'll

  • Gain a comprehensive understanding of our existing security data sources, data pipelines, warehouse, and security operations principles.
  • Contribute to the development and enhancing of our security data and AI model architectures
  • Guide and educate other teams about effective security data and AI practices and opportunities.

Systems

Google Cloud Platform services, GitHub, Looker, Wiz, Google SecOps, Crowdstrike

You'll be successful in this role if you...

  • Data automation and AI-enablement: Develops tooling to automate security tasks (e.g. triaging, routing and tracking findings from vulnerability scanners, alert handlers, compliance monitoring and evidence collection). Can contribute to security-focused codebases. Publishes automation processes or AI tooling to code repositories or an app store. Build and maintain ETL/ELT pipelines and data models within data warehouses.
  • Secure development: Able to build, test and deploy single components in a system with minimal support, and understand how the component fits into the wider architecture. Configure secure cloud environments (GCP). Can describe how code, CI/CD and cloud security posture management (CSPM) tooling works.
  • Decision support and behaviour change: Design and build decision-support and training tools that actively account for human factors. Design and develop intuitive communications, dashboards and reports that guide users toward key insights and minimise cognitive load. Analyse user interaction data to identify where decision-makers struggle and propose concrete design improvements. Proactively reframe security questions or metrics to mitigate common biases, such as presenting data in terms of both gains and losses to avoid framing effects.
  • Mentor Junior Engineers: Actively mentor associate and mid-level security engineers. Provide technical guidance on security and data 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 the CoP.
