Applied Reinforcement Learning Engineer

Centific AI Research advances foundational AI models and applications through reinforcement learning, alignment, and human-centered intelligence. Our mission is to transform data, signals, and human insight into next-generation intelligent systems that redefine enterprise intelligence.

We’re building a governed RL environment platform that enables enterprises to safely iterate and improve AI agent workflows through simulation-based learning, bridging human-labeled signal creation with automated RL training for high-stakes operations.

Role Overview

As an Applied RL Engineer, you will design and build RL environments that simulate complex enterprise workflows and train intelligent agents within them. You’ll work at the intersection of RL research and production systems, translating customer requirements into bespoke simulation environments and post-training pipelines that deliver measurable improvements to AI agent performance.

This role requires deep expertise in both classical RL methodologies and modern LLM-based agent architectures. You’ll shape our product direction and help make RL accessible to enterprise customers who need safe, compliant ways to improve their AI systems., * Design and build custom RL environments (digital twins) simulating enterprise workflows: document processing, compliance, onboarding, support automation

• Deep RL expertise: 3+ years hands-on experience with environment design, reward engineering, policy optimization

• LLM post-training: Experience fine-tuning LLMs using RLHF, DPO, PPO, or similar

• Production skills: Software engineering beyond research with scalable pipelines and training infrastructure

• Agentic AI: Experience with LLM-based agents, tool use, multi-step reasoning

• Technical stack: Strong Python; Gymnasium, RLlib, Stable Baselines; PyTorch/JAX/TensorFlow

• Education: MS/PhD in CS, ML, or related field (or equivalent experience)

Preferred Qualifications

• Publications at NeurIPS, ICML, ICLR, ACL, or similar venues

• Enterprise workflow experience in healthcare, finance, logistics, or compliance

• Open-source contributions to CleanRL, TRL, veRL, or agent frameworks

• Experience with world models, synthetic data generation, and simulation

• Distributed training and large-scale RL experimentation

• Lead the frontier: Shape a new discipline at the intersection of RL, simulation, and enterprise AI

• Ship your science: See your research power real systems across healthcare, finance, and safety

• Collaborate with leaders: Work alongside NVIDIA, Microsoft, and the global AI community

• Build what matters: Create governed, compliant AI systems enterprises can trust.
