At Numasec, we're building AI infrastructure security from the ground up. We're a small founding team working on some of the hardest problems in tech — keeping AI systems secure at the infrastructure level.
We're not looking for a typical security hire. We want people who think in first principles — math and physics graduates who instinctively reach for logic, proofs, and structured reasoning when faced with a hard problem.
• *What you'll work on:**
• Identifying vulnerabilities in AI systems and infrastructure
• Applying mathematical and logical frameworks to real security challenges
• Building tools and methods that protect AI at scale
• Working directly with the founding team — no layers, no bureaucracy
• *What we're looking for:**
• Degree in Mathematics, Physics, or a closely related field
• Strong analytical and logical reasoning skills
• Genuine curiosity about AI and cybersecurity
• Comfortable in a fast-moving, early-stage environment
• Remote-first mindset
