To support this mission, Apify is looking for a Security Engineer who thinks like an attacker. You'll be the second member of the security team. The Apify platform runs code from a global community of builders and powers AI agents through MCP. That's a big attack surface, and we need someone in-house who finds the weak spots before anyone else does. You'll spend most of your time on offense: researching, testing, and hunting. The rest goes to defense: helping engineers fix what you find and improving detection and automation. Red team at heart, purple team in practice. WHAT YOU’LL BE WORKING ON: - Offensive testing: Attack Apify the way a real attacker would: the platform (multi-tenant isolation, Actor sandboxing, Apify Proxy, API, Console), AI agents and MCP servers (prompt injection, tool poisoning, data exfiltration), our supply chain and CI/CD (dependencies, GitHub Actions, open-source projects like Crawlee), and AWS (IAM, network, logging). - AI-assisted security work: Use AI tools daily for pentesting, recon, code review, exploit development, and research. - Security research: Follow new vulnerabilities, attack techniques, and threat actor activity.
