• Solid knowledge of networking, operating systems (Linux, Windows) and web technologies.
• Proficiency with tools such as Burp Suite, Metasploit, Nessus and Kali Linux.
• Familiarity with OWASP Top 10 and modern attack techniques.
• Excellent communication skills – verbal and written, with the ability to explain findings to both technical and non-technical audiences.
• UK or Irish nationality, or an equivalent status that permits full security clearance (sponsorship is not available).

What They Offer:

• Hybrid working – home-based with 2 days per week in our client’s Belfast office or on client site as needed.
• Flexible hours and a supportive, down-to-earth team culture.
• Monthly team lunches and quarterly team days out.
