Penetration Tester / Red Team Specialist (Offensive Security)

Penetration Tester / Red Team Specialist (Offensive Security)

ImpacT Hire is supporting one of our clients - an international technology organization currently building a new Offensive Security team in Bulgaria.

The team was formed recently and is now expanding rapidly, with plans to grow from a small core group to 15–20 specialists in the short term. The focus is strictly hands-on offensive security, penetration testing, and red teaming - not audit or checklist-based consulting.

This role is ideal for experienced professionals who enjoy real-world attack simulations, exploitation, and technical depth, and want to work in a collaborative environment where knowledge sharing and continuous growth are highly valued.

Responsibilities:

➢ Perform technical penetration tests - including scoping, execution, and documentation;

➢ Conduct red team simulations and adversary-style attacks against infrastructure, applications, and user environments;

➢ Identify, analyze, and exploit vulnerabilities across networks, systems, and web/mobile applications;

➢ Perform reconnaissance, information gathering, and attack path analysis;

➢ Prepare clear, detailed technical reports with actionable remediation recommendations;

➢ Communicate findings effectively to both technical and management stakeholders;

➢ Work with diverse environments (Operating Systems, Networks, Active Directory, authentication technologies);

➢ Contribute to team knowledge sharing and mentor junior colleagues when needed.

Requirements:

➢ 3+ years of hands-on experience in Penetration Testing / Offensive Security / Red Teaming;

➢ Strong practical experience with real-world exploitation techniques and attack methodologies;

➢ Good understanding of OWASP Top 10, MITRE ATT&CK framework, and modern attack surfaces;

➢ Experience with infrastructure, web, and/or mobile testing;

➢ Fluent English (written and spoken);

➢ High motivation, ownership mindset, and willingness to continuously improve skills.

Nice to have:

➢ Familiarity with automation of security testing;

➢ Certifications (strong advantage, not mandatory):

• Offensive Security: OSCP, OSWA, OSWP, OSEP, OSWE

• Hack The Box: CPTS, CBBH, CWEE

• Zero-Point Security: CRTO, CRTL

• Altered Security / Penetration Tester Academy: CRTP, CRTI

➢ Technical degree or equivalent practical experience.

What We Offer:

➢ 31+ days paid annual leave;

➢ Premium health & dental insurance;

➢ Food vouchers;

➢ Multisport card;

➢ Coverage for certifications, trainings, and conferences.

If offensive security for you means real attacks, real techniques, and real technical depth - rather than checklists - this role will give you the right environment to practice your craft.
