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.
