Member of Technical Staff - Platform Engineering

Halluminate · San Francisco, CA · 1 wk ago
On-siteInformation Technology$200/hrFull-time

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.

About the role

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.

Requirements

  • 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.
