“Every day, we help enable the green energy transition by building secure, resilient OT solutions that ensure renewable energy assets operate safely and reliably.” - OT Security Architect & Team Lead, Reza Sarafrazjoo.
 
Your tasks & responsibilities 

In our Renewables division, we have major EPC projects in the pipeline for both short- and long-term operations. As an OT Security Architect, you will take the architectural lead and support all OT Security areas across the EPC substation projects.

Your tasks will include but are not limited to:

• Contributing to the implementation of industry-accepted good practice and required Cyber/OT Security architecture at solution level, typically based on standards such as IEC 62443, ISO 27001, and NIS
• Helping define products and standards relevant to OT Security and infrastructure
• Hands-on experience with cybersecurity audits and compliance frameworks, including ISO 27001, Critical Infrastructure regulations, and IEC 62443
• Reviewing requirements/ITT packages and providing input to tenders consisting of calculations, solutions, descriptions, clarifications, and reservations
• Taking on an advisory or active role in infrastructure, identity access management, or logging/event-based activities
• Being responsible for planning, coordinating, and executing FAT, SAT, and SIT activities to ensure successful system delivery and integration
• Implementing customer-specific Cyber/OT Security requirements in substation design for multiple systems and subsystems, such as SCADA, low-voltage, HVAC, Auxiliary Control and Monitoring System, etc.

Crucial to this position is your ability to take ownership of project deliverables and coordinate OT Security deadlines with internal and external stakeholders. You should thrive in a leading role where your skills, collaboration, and structured approach help ensure that requirements are met.
 
Your profile & qualifications

You are a team player who enjoys leading projects and working with stakeholders to align on timing, scope, and objectives. You know when technical expertise should be brought in to support delivery. To us, this means that you have a structured and solution-oriented approach, the ability to influence stakeholders, and the dedication to see tasks through to completion.

You will be part of a team of six colleagues that values quality, attention to detail, and a flexible working environment. We are sociable, helpful, and open to input, and we work in a dedicated, structured, and execution-focused way while respecting the agility that is a natural part of our core tasks. We want the same from you.

To succeed in this position, we imagine that you have:

• A minimum of 5 years of relevant experience in OT Security from a similar position
• A Tech Lead mentality – we are not seeking an extreme subject matter expert, but a well-rounded colleague who can work through heavily structured large projects involving many stakeholders 
• The ability to know when additional technical specialists or resources are needed to complete a project
• Excellent communication skills and fluency in English
• Experience working in complex engineering projects, as well as project and stakeholder management, is an advantage
