OX Security secures the AI-driven SDLC from prompt to production. At OX, we're building the future of cybersecurity for the AI era.

We're looking for a Team Leader to lead our Agentic Pentest team. The team is building a new product: AI agents that autonomously test applications the way a real attacker would. It's a new space that evolves quickly, and you'll help shape both the product and how we build it.

This is a hands-on leadership role. You'll lead senior engineers, stay close to the code, and work with Product and customers to turn real security needs into a working platform.

What You'll Be Doing

• Lead, grow and mentor a team of senior backend engineers
• Stay hands-on: write production code and take part in design and code reviews
• Own architecture and design decisions for an agentic pentest platform: AI agents, task orchestration and scanning at scale
• Work with Product and customers to turn requirements into clear technical plans, and deliver them with high quality
• Set engineering standards for a new product built in an AI-first way

What We're Looking For

• 2+ years leading backend engineering teams (direct management of 3+ engineers)
• 8+ years in backend engineering, including senior-level roles
• Proven experience in security or in agentic AI systems (must): either a role at a cybersecurity product company or security/pentest firm, or hands-on experience building production AI agents (Harness, LLM tool calling, multi-step agents, MCPs) - beyond using AI coding tools
• Hands-on in Node.js/TypeScript or another high-level backend language
• Proven ability to guide architecture and technical decisions for complex systems
• Strong ownership, independence and stakeholder management
• Excellent English
• AI-first mindset: daily, hands-on use of AI tools in your engineering work

Nice to Have

• Offensive security background: pentest, DAST, vulnerability scanning, red-team or attack-simulation tooling
• Experience with both security and agentic AI
• Experience leading a team on a 0→1 product
