Data research lab creating RL benchmarks
Halluminate is a data research lab building benchmarks and RL environments to push the frontier of AI in knowledge work.
Our first area of focus is economically valuable workflows in financial services and consulting, but we are rapidly expanding into adjacent verticals.
Base: $215–275k · Equity: 0.10–0.20% · Location: San Francisco, 5 days in office
Own platform engineering, develop frontier long-horizon RL environments, and help build our engineering org from the ground up.
Build our RL environment training and inference infrastructure to support customer usage at scale.
Research and develop next-generation RL environments — increasingly realistic, long-horizon, and difficult for frontier models.
Build software that 10–100x's the quality and throughput of RL environment creation.
Innovate on synthetic data pipelines to create realistic problems.
Build platform analytics for environment cost, hours, bottlenecks, and SME management.
Craft domain-specific verifiers (verifiable rewards for decks, Excel modeling, quantitative trading, and beyond).
Establish engineering culture and practices from the ground up.
Familiarity building evaluations, benchmarks, or RL for AI agents.
Startup speed: iterate quick, ask quick, respond quick, make mistakes quick.
Strong product and user ownership; ability to prioritize across a large roadmap.
Client-facing comfort — you'll talk to users, customers, and SMEs.
Research background (training models, publishing papers).
Former founders or experience at early-stage startups.
Healthcare — Fully covered medical, dental, and vision for you. Subsidized for dependents.
Relocation — $10k+ relocation stipend to help you get to San Francisco.
401(k) — Up to 4% employer match.
Food — Free breakfast, lunch, and dinner while working.
Health — Free gym membership.
Transportation — Free Ubers and Waymo rides to and from the office.
Visa sponsorship — We sponsor visas, including H-1B.
Data research lab creating RL benchmarks
Halluminate builds benchmarks and reinforcement learning environments to advance AI for knowledge work. It creates computer-use and tool-use environments that train frontier AI models on real finance and consulting tasks, such as investment banking, private equity, and consulting work. A flagship benchmark, Westworld Finance Diligence Bench, contains 88 problems that simulate a complete company acquisition due-diligence process, with content written and reviewed by practicing deal professionals. The company differentiates itself by delivering domain-specific, practitioner-authored tasks and end-to-end workflows across financial services and consulting, and by expanding into adjacent verticals through data-driven RL environments. Its goal is to raise AI performance on real-world knowledge-work tasks and broaden benchmarks to cover more industries, supported by a 2026 Series A funding round led by Oak HC/FT and investors like Y Combinator.
