Head of Security (f/m/d)

1KOMMA5°

We bring together regional craftsmanship and scalable software: We don't think of solar, batteries, heat pumps, and e-mobility as isolated components, but control them as an intelligent, integrated overall system in our virtual power plant. Directly connected to the electricity market - in real time, fully automated. This way, energy is used when it is available from renewables and particularly cost-effective. By 2030, our goal is to transition 1.5 million households to renewable energies. Over 3,000 people are working towards this every day, at more than 80 locations worldwide, from Finland to Australia.

Want to take responsibility and build solutions that truly matter? Apply now and help us shape the energy world of tomorrow.

Your mission

What makes this different from most security leadership roles: we don't only protect data centres and laptops. We run connected energy systems in people's homes, and those systems are part of critical energy infrastructure. You protect exactly the infrastructure that drives the transition towards renewable energy.

This is a hands-on leadership role. You build the team and the framework, and you stay close enough to the technology to make good calls yourself.

Key responsibilities include but are not limited to:

• Leading Team Trust: direction, hiring, growth, health and mentoring.
• Cloud and IoT Security: protect our cloud, our applications, and the connected hardware in our customers' homes.
• Risk and Compliance: own cybersecurity frameworks and the regulations that applies to energy companies.
• Identity and Access Management: internal permissions and secure development that scale with the engineering org.
• Security as a Product: capabilities developers use by default.
• Translating Risk: make security risk concrete for non-technical decision makers, up to C-level.

• Google Cloud Platform, Vercel
• Auth0
• Wiz
• GitHub Advanced Security
• Terraform / Terramate
• Datadog, OpenTelemetry, Incident.io
• Cursor, MCP, and agentic engineering workflows
• TypeScript, Python and GoLang

Your profile

• Several years of experience in security engineering or security leadership, including leading or mentoring engineers.
• A technical background in cloud security, preferably Google Cloud Platform, with enough depth to reason about infrastructure, CI/CD, identity, and application security.
• Startup agility: you have built a security framework from scratch, or close to it, with limited initial resources and a clear view of what matters first.
• Regulatory knowledge: you are familiar with cybersecurity frameworks such as NIST CSF and ISO 27001, and ideally with critical infrastructure rules like NIS2 and KRITIS.
• Strong communication skills and the ability to make security risk concrete for engineers, product managers, and senior business stakeholders.
• A pragmatic, outcome-oriented way of working.
• Excellent English communication skills; German is a plus.

• Hands-on coding experience.
• Experience with security in an AI-assisted engineering setup, including agentic workflows and their guardrails.
• Experience running or coordinating security incident response.
• Experience with security and IT controls in a company preparing for a public listing.
• Experience in a scale-up environment with roughly 100 to 1000 employees.
• Interest in climate tech and renewable energy.
