Description

Design and extend the exploit-generation and validation pipeline behind Cyrion's autonomous agent swarm.

You will sit at the center of Cyrion's offensive capability - the research that decides what our agents are able to find, chain, and prove. This is a hands-on exploit-development role embedded in a product team, not an isolated research function.

What you'll do
  • Design and implement new exploit-generation modules across web, API, and cloud attack surfaces.
  • Build and maintain the sandboxed validation pipeline that confirms every candidate finding before it ships.
  • Reverse-engineer novel vulnerability classes and translate them into repeatable, automatable test logic.
  • Partner with the AI/ML team to improve the agents' hypothesis-generation and attack-chaining reasoning.
  • Triage and reproduce edge cases reported by customers and the validation pipeline.
  • Publish internal writeups and contribute to the public research blog.
What we're looking for
  • 4+ years in offensive security - pentesting, red teaming, or vulnerability research.
  • Comfortable reading and writing exploit code (Python, Go, or similar) against real targets.
  • Deep knowledge of at least two of: web/API exploitation, cloud privilege escalation, mobile reversing.
  • Experience building or operating tooling that automates parts of an engagement, not just running one manually.
  • Clear written communication - you will document findings other engineers rely on.
Nice to have
  • OSCP, OSWE, or equivalent hands-on certification
  • Prior CTF or bug-bounty track record
  • Experience with LLM/agentic-AI attack surfaces

Competitive salary plus meaningful early equity, full health coverage, a $2,000/yr learning budget, and your choice of hardware.
