Security Researcher — Applied Cryptography

Our security research team operates at the boundary between academic cryptography and production systems. We're looking for a researcher who enjoys finding vulnerabilities in cryptographic protocols and building proof-of-concept exploits — then working with engineering to fix them.

Responsibilities

• — Conduct security reviews of cryptographic protocols and implementations
• — Develop proof-of-concept attacks against proposed designs
• — Author research papers and technical blog posts on findings
• — Collaborate with the cryptographer team on protocol improvements
• — Build internal security testing tools and fuzzing infrastructure
• — Monitor and triage external vulnerability reports

Requirements

• — Strong applied cryptography background — you know the difference between IND-CPA and IND-CCA2
• — 3+ years of security research or penetration testing experience
• — Proficiency in at least one systems language (Rust, C, C++)
• — Experience with protocol analysis and formal methods
• — Track record of finding and responsibly disclosing vulnerabilities

Nice to Have

• — Published CVEs or bug bounty recognitions
• — Experience with symbolic execution or SMT solvers
• — Conference presentations (Black Hat, CCC, Real World Crypto, etc.)
• — Familiarity with side-channel analysis (timing, power, EM)
