You will ensure OVO maintains a proactive and automated defence posture, setting the direction for critical security initiatives, and championing the integration of security standards embedded in configs and code and near miss retros to improve our resilience.

    • Utilises principal-level expertise and perspectives to influence vendor relationships and security of third-party contracts.
  • Security risk treatment prioritisation
    • Serve as a trusted challenger and SME, including to senior stakeholders, on trade-offs that appear in designing enterprise-level security systems that carefully balance risk appetite and conflicting priorities (e.g. cost, speed, rigour).
    • Able to innovate with more efficient and effective ways to protect, detect, respond and recover from security threats.
    • Coaches others in security architecture.
    • Defines attack path mapping frameworks that scale and can align organisational risks and mitigation priorities.
    • Directly influence OVO's core model architecture with security best-practice in mind, utilising engineering-first approaches to solve complex security problems.

    • Mentor staff and senior engineers across OVO in advanced security disciplines, strategic thinking, architecture, and technical leadership.
    • Actively contribute to internal communities of practice, develop training for senior staff, and elevate the overall security engineering practice at OVO.

Over OVO Energy

Bedrijfsoverzicht

Naam

OVO Energy

Hoofdkantoor

Bristol, Verenigd Koninkrijk

Opgericht

2009

Grootte

Ongeveer 4.500 medewerkers (bron: ovo.com).

Wat Ze Doen

OVO Energy richt zich op slim energiebeheer en biedt een scala aan producten en diensten aan, waaronder traditionele elektriciteits- en gaslevering, laadoplossingen voor elektrische voertuigen (EV), zonnepanelen, warmtepompen en slimme meters. Het bedrijf is toegewijd aan het vergroten van de integratie van hernieuwbare energiebronnen in zijn aanbod, voornamelijk gericht op particuliere klanten in het VK. Met een klantenbestand van ongeveer vier miljoen huishoudens biedt OVO energie tarieven met groene en hernieuwbare opties, naast innovatieve programma's zoals Charge Anytime, waarmee klanten aanzienlijk kunnen besparen op hun EV-laadkosten (bron: ovoenergy.com).

Projecten & Track Record

OVO Energy heeft aanzienlijke vooruitgang geboekt in de energiesector, waaronder de installatie van 's werelds eerste huishoudelijke voertuig-naar-net EV-lader in 2018. De overname van SSE Energy Services in januari 2020 was een cruciaal moment, waarbij 8.000 medewerkers en miljoenen klanten werden geïntegreerd in de operaties van OVO. Tegen 2025 streeft het bedrijf ernaar om meer dan 1.000 warmtepompen en 500 zonne-energiesystemen in Britse woningen te installeren, wat zijn toewijding aan duurzame energieoplossingen aantoont (bron: ovo.com).

Recente Ontwikkelingen

Begin 2025 kondigde OVO Energy de verhuizing van zijn hoofdkantoor aan naar Crescent at Temple Quay in Bristol, een stap die gericht is op het verbeteren van de duurzaamheid door 3.200 ton CO2e-emissies te vermijden. Bovendien gaven rapporten van juni 2025 aan dat OVO in verkennende fusiegesprekken is met Iberdrola, de eigenaar van Scottish Power, wat het competitieve landschap van de Britse energiemarkt verder zou kunnen hervormen (bron: wikipedia.org).

Werken Bij OVO

OVO Energy biedt een verscheidenheid aan functies in verschillende afdelingen, waaronder energievoorziening, klantenservice, techniek, technologie en duurzaamheid. Met een personeelsbestand van ongeveer 4.500 medewerkers heeft het bedrijf een sterke aanwezigheid in Bristol, Londen en Glasgow. De cultuur bij OVO benadrukt samenwerking en innovatie, zoals blijkt uit de input van medewerkers bij het ontwerp van hun nieuwe kantoor in Bristol. Het bedrijf is eerder erkend voor zijn werkomgeving en stond op de 20e plaats als beste werkgever in het VK in de Sunday Times-lijst van 2017 (bron: ovoenergy.com).
