• Communicate effectively with both technical and non-technical stakeholders
• Stay up to date with current vulnerabilities, exploits, and industry best practices
• Contribute to internal development of tools, research, and process improvement initiatives

What We’re Looking For:

• 1–2 years of hands-on experience in manual penetration testing (infrastructure and/or web applications)
• Strong understanding of TCP/IP, networking concepts, and web application architecture
• Familiarity with tools such as Burp Suite, Nmap, Metasploit, or similar
• Excellent written and verbal communication skills, including report writing and client presentations
• Eligibility for SC Clearance (active clearance is a plus)

Nice to Have:

• Working towards or holding a CREST qualification (CRT, CCT, or equivalent)
• Experience conducting security build reviews across common operating systems (e.g. Windows, Linux)
• Scripting or programming experience (e.g. Python, PowerShell, or Bash)
• Knowledge of MITRE ATT&CK, TTPs, and adversary simulation techniques
• Awareness of broader threat environments and current industry trends

What You’ll Get:

• Competitive salary (up to £60,000, depending on experience)

• Funded training and certification support (CREST, OSCP, or similar)
• Opportunities to progress into red teaming, advanced testing, and leadership roles
