Bugcrowd teams with elite security researchers to reduce risk & improve security ROI through our bug bounty, pen testing, & vulnerability disclosure programs. Backed by General Catalyst.
About the role
The Bugcrowd RL and Reasoning Team focuses on pushing the boundaries of autonomous cybersecurity by building authentic, verifiable reinforcement learning environments for world-leading foundational AI companies. As a Reinforcement Learning Engineer specializing in Reinforcement Learning from Verifiable Rewards (RLVR), you will design and scale automated verification pipelines that transform real-world software vulnerabilities into deterministic reward functions. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- Understanding of RL training workflows used by modern LLM systems, specifically execution-based feedback or Reinforcement Learning from Verifiable Rewards (RLVR)
- Proficiency developing applications in Python and low-level systems programming in C, with Rust experience being a strong plus
- Solid understanding of software vulnerabilities, binary exploitation, fuzzing methodologies, or program analysis
- Experience with DevOps pipelines (e.g., GitHub Actions), reproducible builds (Docker, BuildKit, Nix), and comfort working with Linux systems and low-level debugging
- Experience working with or building benchmark environments (e.g., CTFs, SWE-bench, security challenges, or execution sandboxes)
