Team8 Stealth Cyber Startup - Founding Vulnerability Researcher

Location: Tel Aviv, Israel (IL)

Experience Level: Senior

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.
