Lead APT & Automated Validation Engineer

We are seeking a Lead APT & Automated Validation Engineer who goes beyond traditional penetration testing. This role is for a developer at heart — someone who can orchestrate, script, and chain network and web application exploits to run autonomously, driving continuous and scalable security validation across complex environments.

Responsibilities

• Design and sequence exploit chains that combine multiple vulnerabilities to achieve higher-impact outcomes (e.g., pairing information disclosure with SSRF to reach Remote Code Execution)
• Develop custom exploits and weaponized scripts to automate multi-stage attack scenarios
• Build and maintain automated authentication flows handling OAuth, TOTP, and MFA programmatically
• Configure, scale, and operate continuous automated security validation platforms
• Engineer exploit scripts capable of safely validating vulnerabilities in live production environments without disrupting services or corrupting data
• Analyze network and web application attack surfaces to identify opportunities for automated exploitation
• Collaborate with security and engineering teams to translate manual pentesting techniques into repeatable, automated workflows
• Continuously improve the organization's offensive automation framework and tooling

Requirements

• 5+ years of experience in offensive security, penetration testing, or security engineering roles
• At least 1 year of relevant leadership experience
• Expertise in exploit chaining and attack logic, including sequencing low-severity findings into high-impact compromises
• Proficiency in Python for writing custom exploits and automating complex multi-stage attack scripts
• Experience configuring and scaling continuous automated security validation tools such as Pentera, Cymulate, or Picus, including custom Pentest Robots architectures
• In-depth knowledge of the OSI model and core network protocols (DNS, BGP, TCP/IP)
• Understanding of web application vulnerabilities, including the OWASP Top 10 and API flaws such as IDOR
• Proven capability to engineer automated exploit scripts that safely validate vulnerabilities without crashing network infrastructure or corrupting production databases
• English proficiency at B1+ level or above

Nice to have

• Skills in Bash and/or Go for custom tooling and exploit development
• Familiarity with OAuth flows and programmatic handling of authentication
• Background in bypassing or automating Multi-Factor Authentication challenges
