Red Team Operator in Basingstoke

We are looking for experienced and passionate people who have a background in red team operations, adversary simulation, and offensive security research, who want to take that expertise into meaningful work alongside some of the best in the industry. If that sounds like you, we'd like to hear from you.

The role:

• Plan and execute full-scope red team engagements against mature targets.
• Develop and adapt custom TTPs to bypass modern defensive tooling, drawing on understanding of attacker tradecraft and detection engineering.
• Build and maintain bespoke tooling and implants in support of operations — from initial access through to objectives.
• Conduct threat intelligence‑led assessments where relevant.

The ideal candidate:

• Has hands‑on experience planning and executing multi‑phase red team operations, not just penetration tests.
• Is comfortable developing custom offensive tooling in languages such as C, C#, Rust, Go, or Python.
• Has a solid understanding of both Linux and Windows – authentication mechanisms, trust relationships, and common defensive controls.
• Thinks like an adversary: patient, methodical, and creative when the obvious path is blocked.
• Can communicate findings to a range of audiences without losing technical accuracy.
• Is eligible to hold, or already holds, UK Developed Vetting (DV) clearance – a requirement for the role.
• Is willing to commute to our Basingstoke office.

Desirable technical experience:

• Evasion of modern EDR/XDR solutions and an understanding of detection logic well enough to inform tool development.
• Knowledge of physical security techniques, social engineering, and initial access tradecraft.
• Familiarity with C2 frameworks and the operational security considerations around their deployment.
• Experience with cloud environments (Azure, AWS, GCP) from an offensive perspective – misconfiguration abuse, lateral movement, and privilege escalation.

Salary: Packages are competitive and differ according to experience. Full details can be discussed upon an invitation to interview.

Perks and benefits:

• 25 days annual leave, rising by 1 day per year up to 28 days + bank holidays
• Annual bonus based on company targets
• 6% matched pension
• Training and conference budgets
• Private medical insurance
• Employee assistance program
• 4x death in service
• Cycle to work scheme
• Company socials throughout the year
• Free soft drinks, hot drinks, beer and snacks in office

The location: Role is office based at our office in the centre of Basingstoke, UK – a 6‑minute walk from the train station with easy transport links to London. Please note that due to the nature of our work, candidates must be eligible to undergo UK Developed Vetting (DV) clearance. We are unable to consider applications from candidates who do not meet this requirement.
