About this role
About Halluminate
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.
The role
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.
Responsibilities
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.
You should have
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.
Nice to have
Research background (training models, publishing papers).
Former founders or experience at early-stage startups.
