Role overview
Bryel is an AI-focused research lab and tooling company building infrastructure for post-training evaluation and reliability of production AI agents. The company focuses on automating post-training evaluations, reinforcement learning harness engineering, and continuous reliability testing in production, with the goal of providing the kind of post-training, harness engineering, and continuous evaluation loop that frontier AI labs run internally for their own large-scale models. Its offerings are aimed at teams deploying and maintaining production AI agents, helping them systematically test, measure, and improve model behavior after initial training through automated pipelines and research-driven evaluation methodologies.
What you will do
- Collaborate with the CEO on high-level research and product strategy, translating complex multimodal RL concepts into actionable business roadmaps and organizational milestones.
- Lead the build-out of the company’s operational foundation, including scaling the hiring pipeline for top-tier researchers and organizing exclusive community events to establish industry presence.
- Manage mission-critical business functions, from coordinating strategic partnerships to overseeing day-to-day operations, ensuring the research team remains focused on hyper-alignment breakthroughs.
Who this is a fit for
- Holds an elite technical degree in Computer Science or Research from a top-tier institution like Stanford, Berkeley, or MIT, with the fluency to engage in deep alignment research discussions.
- Possesses a high-signal network within the San Francisco AI/ML ecosystem and a natural instinct for community building, organizing elite dinners, and attracting world-class talent to the lab.
- Demonstrates exceptional operational judgment and “pull,” ideally combining a strong technical background with an MBA or prior experience in a high-growth startup leadership environment.
Why this role is remarkable
- Founding-team impact: Shape the strategic direction and culture of a frontier AI lab from day one alongside a founder with deep expertise in Apple Intelligence and Berkeley AI research.
- Elite Technical Ecosystem: Work at the cutting edge of multimodal RL and post-training infrastructure, moving beyond simple dashboards to build the core systems that define AI agent behavior.
- Career Acceleration: Join with a clear, defined trajectory to transition into the COO role as the company scales its operations and technical team within the SF AI community.
