Member of Technical Staff, Platform Engineering

What we're looking for:

We need a highly technical engineer with deep experience in distributed systems, LLMs, and simulation infrastructure who can operate with extreme ownership and a founder mentality. You should be comfortable working across the full stack—from customer-facing products to internal infrastructure—and have a track record of building systems that scale to billions of events. Bonus points if you have experience with reinforcement learning, AI agents, or prior founding experience.

What you'll do:

Own and extend key parts of the core simulation engine, adding new features and improving performance metrics such as throughput and cost

Build and scale infrastructure capable of handling 10B+ events and tens of thousands of monthly users (both human and virtual)

Work directly with the Head of Engineering to architect, build, and deploy projects across customer-facing products and internal systems

Leverage coding agents (Codex, Claude Code) to accelerate development velocity and establish best practices

Establish engineering culture and standards as the technical team continues to scale

Stay current with SOTA research in evaluations, RL, and agent architectures, translating papers into production systems
