Senior Backend Engineer - Posture (Cybersecurity)

TL;DR

Senior Backend Engineer (Posture): Building AI-driven agents and simulation engines that emulate adversarial behaviors in enterprise environments with an accent on attack path modeling, orchestration, and integration with proprietary AI models. Focus on designing scalable systems for lateral movement, privilege escalation, persistence, and discovering security gaps before real attackers.

hirify.global combines AI and human expertise to create cybersecurity products protecting nations and critical infrastructure with proprietary Cyber Language Models.

What you will do

• Design and build AI-driven agents emulating adversarial behaviors like lateral movement, privilege escalation, and persistence.
• Develop core simulation and orchestration components in Go and integrate with in-house AI models.
• Model and simulate attack paths across complex enterprise environments including identity, endpoint, network, and cloud.
• Collaborate with red-teamers, researchers, and data scientists to translate threat intelligence and TTPs into executable logic.
• Contribute to architecture decisions, scalability, and performance optimization for distributed simulations.

Requirements

• 7+ years of hands-on software engineering experience in a modern language (Go preferred; Python, Node.js, or C++).
• Strong cybersecurity engineering background with deep understanding of attacker TTPs, lateral movement, privilege escalation, credential abuse, and network exploitation.
• Familiarity with enterprise security environments (Active Directory, cloud infrastructure, EDR/XDR, network segmentation).

Nice to have

• Experience building AI/ML-driven systems or agent-based simulations.
• Experience as a red teamer, penetration tester, or security researcher.
• Knowledge of graph modelling or graph databases (e.g., Neo4j) for attack-path representation.
