The posting
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:
- You'll plan and execute full-scope red team engagements against mature targets.
- You'll develop and adapt custom TTPs to bypass modern defensive tooling, drawing on your understanding of attacker tradecraft and detection engineering.
- You'll build and maintain bespoke tooling and implants in support of operations - from initial access through to objectives.
- You'll 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. Due to the nature of our work, this is 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.
Life at Interrupt Labs
We know that what draws people to offensive security work is the research itself but we also think the people doing that work deserve to be properly looked after. Here's what that looks like in practice…
Rewarded for the work you do
- Annual bonus up to 15% based on company performance - when Interrupt does well, that gets shared across the team, not kept at the top.
- 6% matched pension
- 4x base salary Death in Service, so your family has a financial safety net without you having to think about it.
- Salary sacrifice EV scheme, so going electric is more affordable through your pay.
- Low-interest loans up to £10,000, for whatever life throws at you - big purchases, unexpected costs, or just breathing room.
Taking care of you
- Private medical insurance with access to private GP consultations, mental health cover and various therapies cover (chiropractic treatment, osteopathy, acupuncture, homeopathy, podiatry/chiropody and up to two consultations with a dietician).
- Employee Assistance Programme, with 24/7 confidential support.
- Enhanced cycle to work scheme which can be used for a bike valued up to £10,000.
Time to switch off
- 25 days annual leave, rising by a day each year up to 28, plus bank holidays, because good research needs a rested mind, not a burnt-out one.
- Option to buy up to 5 additional days' leave each year, if you want more flexibility than the base allowance gives you.
Growing your craft
- If there's a certification, course, or conference that will genuinely make you better at your work, whatever it is - we want to hear about it and back it.
- Dedicated conference budget, because staying close to the research community matters.
Supporting your family
- Enhanced maternity pay: 12 weeks at full pay, followed by 12 weeks at half pay.
- Enhanced paternity pay: 4 weeks at full pay.
Culture & office life
- Regular company socials throughout the year.
- Free hot and soft drinks, beer and snacks in the office, because the small daily things add up.

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).
