About The Position

We’re building the post-training platform that makes AI deployments safe, transparent, and continuously improving by productising frontier LLM and interpretability research. At Parsed, we supercharge large language models with reinforcement learning, enabling them to adapt and improve continually in real-world use. Instead of static black boxes, our models evolve with feedback, aligning more closely with user needs and outperforming one-size-fits-all generalist models. We pair this with cutting-edge mechanistic interpretability to turn opaque systems into transparent ones so they can be trusted by humans, approved by regulators, and relied on for mission-critical workflows. Just as Stripe set the standard for secure, simple payments, Parsed is setting the standard for safe, adaptive, and continually learning AI.
