Kaluza is the Energy Intelligence Platform, turning energy complexity into seamless coordination. We help energy companies overcome today's challenges while accelerating the shift to a clean, electrified future. Our platform orchestrates millions of real-time decisions across homes, devices, markets and grids. By combining predictive algorithms with human‑centred design, Kaluza makes clean energy dependable, affordable and adaptive to everyday life. With teams across Europe, North America, Asia and Australia, and a joint venture with Mitsubishi Corporation in Japan, we power leading companies including OVO, AGL and ENGIE, as well as innovators like Volvo and Volkswagen.

You’ll be joining the Information & Cyber Security team, a core part of our Platform & Security Engineering organisation. Security at Kaluza isn’t a silo — you’ll work closely with colleagues across security engineering, application security, identity and access management, cloud security, and security architecture.

Building, mentoring and coaching a high‑performing Security Operations team across the UK and Australia. You’ll create an environment of continuous learning, clear ownership, and psychological safety — where your team feels empowered to act decisively under pressure.

Evolving and developing our incident response processes end‑to‑end. You’ll ensure our response capabilities meet regulatory and contractual compliance obligations, develop and maintain playbooks and standard operating procedures, and run exercises that build team confidence and reduce uncertainty when it matters most.

Building out a dedicated response capability for AI‑related security incidents — a genuinely novel challenge. You’ll develop playbooks for AI‑specific threat scenarios, run tabletop and live exercises, and work hand‑in‑hand with our Security Engineering team to build the safeguards and controls needed to reduce impact and improve resilience.

Proactively hunting for threats across our environment before they become incidents. You’ll engage with penetration testers, red teams and bug bounty programmes to surface weaknesses in our defences, and work with Security Engineering, Application Security and our broader engineering and technology teams to close gaps and strengthen our controls.

Owning our security monitoring and detection capability — SIEM, SOAR, EDR, and threat intelligence platforms. You’ll drive the tooling roadmap, tuning detections to reduce noise and increase fidelity, and champion automation to keep pace with the threat landscape.

Defining and owning the Security Operations KPIs and KRIs that matter. You’ll produce clear, concise reporting for senior stakeholders and leadership on the health of the function — including mean time to detect, mean time to respond, and coverage trends.

Ensuring our security operations posture supports Kaluza’s regulatory and contractual obligations. You’ll act as a key stakeholder in audits, assessments and customer security reviews, and maintain close alignment with our Legal, Compliance and Privacy teams.
