Job summary

RoboService seeks a Senior ML Engineer to bridge remote-controlled hardware and autonomous robots on the factory floor. You will establish training pipelines, from teleoperation data collection to fine-tuning VLA models, and apply reinforcement learning to improve manipulation and locomotion tasks.

You will use high-fidelity simulators to validate agents before deploying to real hardware. Required is 3–5+ years in robotics or embodied AI, strong Python and DL framework skills, and experience

Qualifications

• MS or PhD in Robotics, CS, AI, or related field.
• 3–5+ years hands-on experience in robotics, deep learning, or embodied AI.
• Strong proficiency in Python and deep learning frameworks (PyTorch, TensorFlow, or JAX).
• Experience with Transformers and VLA architectures is highly desirable.
• Robotics Middleware: familiarity with ROS2 (Robot Operating System).
• Simulation: experience with physics-based simulators (NVIDIA Isaac Sim, Gazebo, MuJoCo).
• Data Engineering: manage high-quality demonstration datasets, automate data cleaning, and train pipelines.
• C++ experience is desirable.
• Proficiency in English; basic German a plus.

Responsibilities

• Fine-tune VLA models (open source and partner models).
• Manage Data Pipeline and Teleoperation/Imitation Learning activities for data quality.
• Oversee large datasets required for fine-tuning models.
• Apply RL techniques to fine-tune robot actions for robust production-line performance.
• Use high-fidelity simulators (Isaac Sim, Omniverse) to train and test agents before deployment.
• Collaborate with hardware teams to bridge software and hardware integration.

Job description

Company Description

RoboService solves the "Last Mile" of humanoid robotics. While manufacturers provide the hardware and foundation models, these general-purpose "brains" are not yet ready for the specific, accurate tasks of a production line. We bridge that gap. We don't build foundation models from scratch; we operationalize them. We take state-of-the-art VLA models and fine-tune them for reliability, speed, and precision in real-world manufacturing environments. We are not a research lab; we are shipping code that moves atoms. Launched in July 2025 by repeat founders with successful exits, we are looking for engineers who want to take robots out of the lab and onto the factory floor.

Role Description

We are looking for Senior ML Engineer to bridge the gap between "remote controlled hardware" and "autonomous robots". We work with robotics manufacturers that provide great hardware and a model infrastructure, but are missing the software to fine-tune the models on a specific task. Your primary focus will be establishing training pipelines—from teleoperation data collection to fine-tuning VLA models—and utilizing Reinforcement Learning (RL) to fine-tune complex manipulation and locomotion tasks. You won't be writing papers. You will be:Fine-tuning VLA models (open source and proprietary models from our partners)Managing the Data Pipeline and overseeing the Teleoperation and Imitation Learning activities for data quality. Manage large datasets required for fine-tuning models.Reinforcement Learning (RL): Apply RL techniques to fine-tune robot actions, ensuring robust performance when the robot works on the production line.Utilize high-fidelity simulation environments (NVIDIA Isaac Sim, Omniverse) to train and test agents before deploying them to physical hardware.
