Offensive Security Consultant / Penetration Tester
Location: Full Time – Remote
Who this role is for: You are an experienced penetration tester who prefers deep manual work over scanner-driven checklists. You enjoy chaining findings, building proof-of-concept tooling, thinking like an adversary, and explaining technical risk clearly.
The person we’re looking for: You combine technical depth with humility, curiosity, clear communication, strong judgment, and a bias toward practical solutions.
What You’ll Do
- Lead manual penetration tests across network, web/API, cloud, wireless, thick client, and enterprise environments
- Execute objective-based red team and adversary simulation engagements when in scope

- Produce clear reports with attack narratives, evidence, business impact, and remediation guidance
- Contribute to HALOCK methodology, tooling, lab work, research, and deliverables.
- Participate in project kickoff and report delivery meetings
- Mentor by example through sound judgment, clean execution, and professional communication
What You Bring
- 5-7+ years of hands-on experience in penetration testing, offensive security consulting, or red team operations
- Depth in at least one major domain, such as network, Active Directory, web/API, cloud, or red teaming
- A skills-based certification or equivalent practical proof of ability
- Proficient with common industry tools and C2 frameworks
- Scripting or coding ability useful for automation, tooling, or exploitation
- Working knowledge of PTES, OWASP, MITRE ATT&CK, and related offensive security references
- Strong client-facing communication and ability to deliver with minimal supervision
Bonus Points
- Previous experience conducting penetration testing in a consulting capacity
- Experience testing cloud, identity, EDR-protected endpoints, or mature enterprise networks
- Ability to translate offensive security findings into compliance-relevant risk and remediation guidance
- Experience with malware development, C2 framework enhancements, and EDR evasion

Why Strong Testers Join HALOCK

What you can expect: remote-first work, challenging client environments, paid training and certifications, conference opportunities, experienced teammates, and room to improve methodology.
How We Work
We work as a high-trust, low-ego team that shares techniques, debriefs hard findings, challenges assumptions, and helps each other improve.
You will have room to go deep technically, improve methodology, contribute to research and tooling, and deliver work clients can rely on.
