Job description

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

We offer

• We gather like-minded people:
  • Top tech minds driving innovation in AI, cloud and digital platform modernization
  • Supportive team and agile, startup-like culture
  • Hybrid by design mode and opportunity to work remotely within Poland
  • Chance to work abroad for up to 60 days annually
  • Business-driven relocation opportunities
• We provide growth opportunities:
  • Career development programs
  • Thought leadership, mentoring, soft skills and well-being programs
  • Certification (Anthropic, Gemini, GCP, Azure, AWS)
  • English classes
• We cover it all:
  • Stable pay
  • Participation in the Employee Stock Purchase Plan with a 15% discount
  • Benefits package (health insurance, multisport, shopping vouchers)
  • Referral bonuses up to $2,000
  • Offices featuring entertainment and relaxation zones, table tennis and football, free snacks, coffee and more
  • Corporate, social and well-being events
• Please, note:
  • Benefits listed above are available to employees only
  • We are open for working with Contractors. Terms of B2B cooperation agreements are agreed individually
  • We will reach out to selected candidates exclusively
