Description
St1 is an energy transition company with the vision to be the leading producer and seller of CO₂-aware energy. St1 operates in Finland, Sweden, Norway, and the United Kingdom. Our portfolio encompasses oil products, biogas, Sustainable Aviation Fuel (SAF), renewable diesel (HVO) and solar power. St1 has 1,150 retail stations across Finland, Sweden and Norway. Together, we’re more than 1,000 curious, committed and caring people here to change the game. Ready to challenge the ordinary with us?
We are looking for an OT Cybersecurity Engineer to take ownership of cybersecurity across this OT estate. This is a role for someone who is equally at home writing a security standard and sitting at a terminal working through network segmentation, firewall rules, and monitoring coverage. You understand that OT is not IT: long lifecycles, availability comes first, patching windows are scarce, and a security decision can have safety and environmental consequences.
• Driving the correct, site-by-site rollout of our OT cybersecurity architecture.
• Setting and maintaining OT security standards aligned to ISO/IEC 27001, IEC 62443, the CIS 18 Controls, and NIS2 obligations in Finland and Sweden.
• Working hands-on across the IT infrastructure that supports OT and across OT systems themselves, to the level needed to specify and validate controls, not to run the plant.
• Guiding and, where needed, firmly challenging OT vendors on cybersecurity.
We’re looking for a colleague with the drive to challenge, collaborate and grow. To thrive in this role, you likely have:
• A proven track record implementing OT cybersecurity, at least at large production-site level, and multi-site experience is a real plus.
• A genuine mix of governance and technical skill.
• Strong knowledge of OT-specific constraints and how they differ from IT security.
• The confidence to challenge vendors and the credibility to make it stick.
• CISSP or equivalent certification.
• Fluent English (mandatory); Finnish, Swedish, or Norwegian is preferred.
• A proactive, can-do mindset and the appetite to work in a lean, fast-moving organisation where you build the structure rather than inherit it.
• Willingness to travel across the Nordics and the UK.
- A high-impact role at the centre of critical energy infrastructure and the energy transition.
- Full ownership to shape and mature OT security across St1.
- Backed by a strong CISO function and 24/7 SOC/NOC partners.
- Security work that protects people, safety, and the environment.
- A talented Nordic technology organisation built on trust, freedom, and responsibility
At St1, your safety and wellbeing come first. We offer an open and inclusive workplace where you’re respected and trusted to take initiative. In a hands-on, informal culture — and a business that never stands still — there’s room to explore ideas and take on new challenges. We support your journey through learning and opportunities to grow across teams and countries.
We welcome applicants from all backgrounds and are committed to an inclusive and equitable recruitment process.
