As a company at the forefront of the energy transition, they offer a mission-driven environment where your work directly contributes to combating climate change. The remote-first UK-based role allows you to work flexibly while making a tangible impact on critical infrastructure security.

About This Role

As a Cyber Security Engineer and Architect, you will lead the creation of cyber architecture roadmaps and standards for both IT and OT systems, ensuring the security of renewable energy infrastructure. You act as the design authority, guiding solution proposals and overseeing continuous security improvements. This role is pivotal in protecting assets that generate clean power for millions, making your work highly visible and impactful.

💡 A Day in the Life

Your day might start with a review of security architecture proposals for a new solar farm, followed by a stakeholder meeting to align on OT security standards. You could then work on updating the cyber security roadmap, model a new network design using architecture tools, and later support the incident response team in analyzing a potential threat. The role balances strategic planning with hands-on technical oversight, all while collaborating remotely with global teams.

📝 Tips for Applying to Renewable Energy Systems

1

Tailor your CV to highlight OT security experience alongside IT; explicitly mention any work with SCADA, PLCs, or industrial control systems.

2

In your cover letter, connect your experience to the energy sector; explain how you've applied frameworks like NERC-CIP or NIST-CSF in a critical infrastructure context.

3

Showcase specific architecture projects where you designed roadmaps or patterns that improved security posture; quantify results if possible.

4

Prepare a portfolio or summary of your architecture modeling work (e.g., using tools like ArchiMate or Sparx EA) to demonstrate technical depth.

5

Research Renewable Energy Systems' recent projects and press releases to align your application with their current priorities, such as offshore wind or solar expansion.

✉️ What to Emphasize in Your Cover Letter

Emphasize your experience with OT security and how you've applied cyber frameworks to protect industrial environments. Highlight your ability to lead architecture decisions and influence stakeholders. Connect your motivation to the company's mission of clean energy expansion. Mention any specific technologies (e.g., firewalls, vulnerability scanners) you've deployed in similar roles.

🔍 Research Before Applying

To stand out, make sure you've researched:

  • Review Renewable Energy Systems' latest annual report or sustainability page to understand their growth plans and technology focus.
  • Look into their specific OT systems and any public case studies on security incidents or innovations in the renewable energy sector.
  • Understand the UK's energy security regulations and how they impact the company's operations, such as the Energy Act 2023 or NIS Regulations.
  • Check the company's LinkedIn or news for recent hires or projects in cyber security to gauge team structure and priorities.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 How would you develop a cyber architecture roadmap for a new wind farm integrating IT and OT systems?
2 Describe a time you had to influence a stakeholder to adopt a security standard (e.g., NERC-CIP) in a resistant team.
3 How do you approach vulnerability management in OT environments where patching is not always feasible?
4 Explain how you would ensure security architecture aligns with business objectives while meeting regulatory requirements.
5 What experience do you have with incident response in OT systems, and how would you improve recovery processes?

⚠️ Common Mistakes to Avoid

  • Avoid focusing solely on IT security without demonstrating OT/ICS knowledge; this role explicitly requires both.
  • Don't give generic answers about frameworks; be prepared to discuss how you've applied ISO27001 or NIST-CSF in an industrial setting.
  • Avoid neglecting the 'architect' aspect; emphasize your ability to create roadmaps and patterns, not just implement security controls.
