Lead Security Engineer

Lead Security Engineer

Hybrid/Remote (N.Ireland wide) | Ability to obtain SC Clearance

Are you a senior security engineer ready to lead, shape, and grow a high-performing penetration testing function? We are looking for a technical leader who can set direction on security methodology, embed best practice across agile delivery teams, and develop the next generation of security talent.

Role

This is a broad security engineering leadership role, not a pure penetration testing position. You will set direction on security methodology and tooling, work shoulder to shoulder with agile delivery teams to build security in from the start, and develop a small team of security engineers. Client-facing consultancy and the ability to communicate security risk clearly to varied audiences are just as important as technical depth.

Day-to-day

• Leading penetration tests across web applications, networks, and infrastructure
• Embedding security into CI/CD pipelines and conducting source code reviews
• Defining and evolving security testing methodology, tooling, and engagement scoping
• Advising customers and delivery teams on security best practice throughout the development lifecycle
• Coaching and developing a small team, supporting their performance and careers
• Translating security complexity clearly for both technical and non-technical audiences
• Staying current on emerging threats and attack types

Experience

• Expertise securing web applications and cloud platforms (AWS or Azure)
• Hands-on experience with manual and automated security testing, including penetration testing
• Strong knowledge of NCSC, NIST, OWASP ASVS, GDPR, and PCI standards
• Solid understanding of common attack vectors including OWASP Top 10, XSS, SQL injection, and MITM
• Experience embedding Continuous Security into CI/CD pipelines and agile delivery
• Proven ability to mentor, coach, and develop team members
• Scripting or programming skills across Windows, Linux, or macOS

Nice to Have

• OSCP, CREST, or TIGER qualification
• Experience with Burp Suite, OWASP-ZAP, Nmap, Nessus, or Metasploit
• Experience working with external pen test providers and translating findings into actionable tasks
• Active involvement in the security community, conference speaking, or knowledge sharing

Package

• Up to £85k salary
• Share options
• Hybrid/remote working across UK
• 35 days annual leave including statutory
• Enhanced pension scheme
• Private health cover

⚠️ Applicants must be eligible for UK Security Check (SC) clearance. This role requires SC clearance or the ability to obtain it prior to starting.
