Persona's founding team has a decades-long history in humanoid robotics, bionics, and product development delivering robust hardware that has touched the stars, worked miles below the surface of the ocean, roamed Disney Parks, and has even been featured on a US postage stamp. Our mission is focused squarely on shipping beautiful, reliable products at massive scale, while building a customer-focused team to achieve these aims.\nRole Overview:\nWe are looking for aReinforcement Learning Engineer to join our Manipulation team, focused on dexterous grasping. Our goal is to ship capable, reliable grasping policies on real hardware with high-DOF robotic hands. We are looking for someone who can follow recent advances in reinforcement learning and related learning-based methods, judge what is practically useful, and adapt those ideas on our platform. If you are earlier in your career but exceptional, we want to hear from you; equally, a more experienced candidate who brings deep RL expertise will thrive here.\nYour Role:\nTrain and iterate on reinforcement learning policies for complex grasping tasks including functional grasping, tool use, in-hand manipulation, and environment interaction.\n\nImplement and refine sim-to-real transfer pipelines to bridge the gap between simulation and physical robotic hand performance.\n\nDevelop reward functions, curriculum strategies, and training environments in MuJoCo and Isaac Lab.\n\nRun experiments on real robots alongside simulation, evaluating and debugging policy behavior on hardware.\n\nMonitor, evaluate, and adapt state-of-the-art research in learning-based grasping to deploy on our humanoid platform.\n\nCollaborate with the rest of the software team to deploy end-to-end grasping systems.\n\nBenchmark and evaluate grasp policies across object diversity, clutter scenes, and real-world uncertainties.\n\nIntegrate tactile sensing and feedback into grasp policies for robust, force-aware manipulation.\n\nWe're Looking For:\nBS, MS, or PhD in Robotics, Computer Science, Machine Learning, or a related field.\n\n2+ years of hands-on experience in reinforcement learning for robotic manipulation; exceptional recent graduates from relevant research labs will be considered.\n\nDemonstrated ability to read, understand, and implement ideas from recent robotics and machine learning research.\n\nHands-on experience training RL agents for robotic manipulation tasks, including reward shaping and policy evaluation.\n\nExperience with sim-to-real transfer: domain randomization, physics tuning, or real-world policy validation on hardware.\n\nProficiency in Python and deep learning frameworks (PyTorch, JAX), along with RL libraries such as rsl_rl or skrl.\n\nExperience preparing meshes and collision geometries for RL environments in simulators such as MuJoCo and/or Isaac Sim.\n\nBonus Qualifications:\nExperience deploying RL-trained policies on physical robotic hands.\n\nExperience with tactile sensors and integrating tactile feedback into learned grasp policies.\n\nExperience with contact-rich manipulation and force/torque estimation.\n\nFamiliarity with other learning-based approaches such as behavior cloning, imitation learning, or diffusion-based policy methods.\n\nPublications or project work at top-tier venues (CoRL, RSS, ICRA) on grasping or dexterous manipulation.\n\nExperience in a humanoid robot startup environment.\n\nWhy Join Persona AI?\nWe offer competitive compensation, a performance-based bonus, 99% employer covered medical benefits, early-stage equity, competitive PTO, and a company-wide paid winter break between December 24th and January 2nd.\n\nYou’ll shape technology that’s redefining the possibilities of robotics and human interaction.\n\nWork alongside passionate teammates who value creativity, collaboration, and continuous learning.\n\nEnjoy full access to advanced tools, hardware labs, and the freedom to push the boundaries of what robots can do.\nPersona AI is an Equal Opportunity Employer.\n All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, national origin, sexual orientation, gender identity, age, disability, veteran status, or any other characteristic protected by applicable federal, state, or local law.","description_format":"text","description_chars":4339,"description_truncated":false,"requirements":{"experience_years_min":2,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Continuous
