Pramaana Labs is a frontier AI lab building the verification layer for high-stakes AI. We turn complex domain knowledge into machine-checkable systems that return proofs, counterexamples, and traceable explanations. Backed by Accel.
About the role
We're training foundation models to natively interact with symbolic world models. As an RL Post-Training Researcher, you'll take foundation models and scale their reasoning capabilities: applying RLVR to new domains using verified rewards from the Lean kernel, pushing the frontier of autoformalization and proving, and innovating on RL algorithms, data, and evals. Your work will also define how our models leverage test-time compute to solve long-horizon logical tasks.
What they're looking for
- Deep, hands-on research experience in reinforcement learning applied to reasoning models at scale
- Experience working with RLVR, test-time RL, or exact deterministic reward signals
- Strong algorithmic and systems intuition — comfortable writing custom RL loops, managing data pipelines, and building robust evals from scratch
- High autonomy: the ability to take a fuzzy problem area and independently drive it to state-of-the-art results without day-to-day direction
More about this role
Pramaana Labs is a frontier AI lab building the verification layer for AI. Founded in 2025 and headquartered in Palo Alto, we turn complex human knowledge, including tax codes, legal rules, clinical guidelines and security protocols, into a formal representation, so every AI answer can be traced, challenged, and proved.
Pramaana's architecture pairs foundation models trained to formalize and reason with a symbolic world model encoded in Lean 4. Pramaana was founded by a team out of Google, DeepMind, and Glean, combining frontier AI researchers and formal methods experts.
