## About Halluminate
Halluminate is an applied AI and data company building computer-use and tool-use RL gyms to train AI agents on real financial services work — Excel modeling, pitch decks, and everything investment banking, private equity, and hedge funds rely on. We work with frontier labs, graduated from Y Combinator (S25), and raised a seed round to scale the team.
## The role
**Base:** $200–275k · **Equity:** 0.15–0.30% · **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.
