Team8 Stealth Cyber Startup - Founding Vulnerability Researcher

Description We are a fast-growing stealth cyber startup, backed by Team8, on a mission to solve one of the most critical challenges in the modern cyber landscape. We are looking for a brilliant Founding Vulnerability Researcher to join our core R&D team and help shape the technical heart of our product from the ground up. Role description We are looking for a strong offensive security researcher to join our core team, become a true partner in building the product end-to-end, and take a key role in shaping our research methodology, technical direction, and product capabilities. This is a hands-on role in a small team, sitting at the intersection of world-class offensive research and core agentic AI research — with a lot of responsibility, autonomy, and influence over the technical and business direction. What you will do • Discover novel vulnerabilities, attack primitives, and exploitation techniques across various surfaces. • Build reliable, weaponizable proof-of-concepts that hold up in real production environments. • Translate offensive techniques and original research into real product capabilities. • Develop methodologies that mirror how top attackers actually operate end-to-end. • Stress-test the product against hardened targets and push the ceiling of what it can do. • Represent the company in the research community through talks, papers, and disclosures. Requirements • 5+ years of hands-on experience in offensive security research or exploit development. • Demonstrable track record of offensive work — previous roles, bug bounty, CTF reputation, published CVEs, or original research. • Deep expertise in at least one offensive domain — web/app vulnerability research, cloud, identity, kernel/OS internals, network protocols, or AI/LLM security. • Comfortable in Python, Go, or Rust, with the ability to ship research into production-quality code. • Comfortable with ambiguity and zero-to-one work; founding DNA and a strong sense of ownership. • High proficiency in English, written and spoken. • Based in Tel Aviv, in-person — this is a founding team role.
