Research Internship - United States

Flexion Robotics • San Francisco, CA

14h • Onsite

About The Position

Flexion is building the intelligence layer for the next generation of humanoid robots, aiming to accelerate the transition from prototypes to real-world deployment. Founded by leading scientists in robot reinforcement learning, Flexion has already achieved significant milestones and is now expanding its research team in the United States, specifically in San Francisco. This internship is for highly capable and ambitious early-career robotics researchers who are driven to push the boundaries of what robots can achieve. Interns will join Flexion's US research team, tackle critical research problems, and deploy solutions on actual hardware. They will collaborate directly with a world-class, international team on novel challenges. The internship is designed to provide exceptional graduate researchers with the opportunity to make a significant impact in a dynamic industrial research setting, with a potential pathway to a full-time Research Scientist position.

Requirements

• Ongoing PhD in Robotics, Machine Learning, or a closely related field, or a recently completed Master's degree with exceptional research output.
• Demonstrated experience deploying learning-based controllers on real robotic hardware, or strong research signal that you can do so quickly.
• Strong working knowledge in: Reinforcement learning.
• Strong working knowledge in: Physics-based simulation (Isaac Gym/Lab, MuJoCo, or equivalent).
• Strong working knowledge in: Python and PyTorch, including training neural networks at scale.
• Knowledge in at least two of the following: Diffusion models, Flow matching, Dexterous manipulation, Sim-to-real transfer and real-to-sim calibration, Whole-body control and loco-manipulation, Synthetic data generation for robot learning, Vision Language Model Fine-Tuning (SFT and RL-based), Transformer-based 3D Scene Understanding.

Responsibilities

• Take on research problems that matter most.
• Deploy real solutions on real hardware.
• Work directly with a world-class team across two continents on challenges that have no published answers yet.
• Do your highest-impact work in a fast-moving industrial research environment.

Benefits

• Competitive compensation package
• A front-row seat at one of the world’s most ambitious robotics companies
• An energetic, collaborative team with a relentless bias for action
• The opportunity to build something no one has ever done in this field - alongside the world’s leading researchers
