Senior/ Lead Security Engineer
Full-Time
Glasgow / Remote | £81,000 + bonus of up to 30%
On behalf of a leading UK energy business, we're recruiting for an experienced Senior Security Engineer to take ownership of a strategic Security Engineering programme across a critical, nationally significant infrastructure estate. This is a fantastic opportunity for a security-focused engineer to shape compliance, resilience and innovation across a complex and evolving operational environment.
The Role
You'll lead the delivery of security engineering compliance, including work aligned to the NIS regulations, while driving forward initiatives that balance risk, performance and cost across the business's technical estate. Reporting to the Security Engineering Manager, you'll play a key role in shaping how security is embedded into both cyber and physical infrastructure, working closely with engineering, asset management and operational teams.
You'll take responsibility for a capital investment portfolio worth millions per year, ensuring projects are delivered on time, within budget and in line with strategic priorities. You'll also line manage a small team, with the scope to bring in graduate trainees or apprentices as the function grows, and step in to support wider management responsibilities as needed.
