Team8 Stealth Cyber Startup - Founding Vulnerability Researcher

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. 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.
