Job summary

Zeromatter Technologies Inc. is seeking a Robotics Research Engineer to design, train, and evaluate robotics policies—from imitation to reinforcement learning—to advance Zeromatter's simulation platform and its real-world validation across customer use cases.

You will collaborate with the Dynamics team to improve physics-based simulation fidelity, run experiments in simulation and the lab, and build scalable tooling in Python, Rust, and C++.

Qualifications

• Engineering degree or equivalent hands-on experience in robotics or related field.
• Experience training and evaluating robot learning policies in industry, lab, or academia.
• Hands-on experience with physical robots, data collection, experiments, and debugging hardware/software.
• Proficiency in Python, Rust, and/or C++, with ML frameworks such as PyTorch, TensorFlow, or JAX.
• Comfort iterating quickly between simulation and real-world validation.
• Familiarity with sim-to-real transfer challenges like domain randomization and system identification.

Responsibilities

• Design and run experiments training robotics policies (imitation learning, reinforcement learning, VLA models) primarily in simulation.
• Work hands-on with physical robots to collect real-world data and validate sim-trained policies.
• Collaborate with Dynamics team to identify simulation fidelity gaps affecting transfer performance and prioritize fixes.
• Build and maintain data pipelines and evaluation frameworks/benchmarks for policy training and transfer performance.
• Prototype new tasks and domains grounded in real customer use cases to expand platform capabilities.
• Read, evaluate, and adapt techniques from state-of-the-art robot learning research for Zeromatter's platform.
• Contribute findings to customer-facing materials and demonstrations.
• Build reusable libraries and tooling (in Python, Rust, and/or C++) to support work at scale.

Job description

As a Robotics Research Engineer on our Robotics team, you'll design, train, and evaluate robotics policies from imitation learning to reinforcement learning to foundation/VLA models using Zeromatter's simulation platform, then validate, and iterate against real hardware. This work is grounded in real customer use cases as much as internal research goals. The manipulation and automation tasks you train and validate often trace directly back to a problem a customer is trying to solve. You'll work closely with our Dynamics team, who own Physics Engine development, to make sure the simulator keeps pace with what policy training needs. You'll be running the experiments, in sim and in the lab, that push our simulator's fidelity and our policies' transfer performance forward together. Responsibilities may vary from month to month, but here are some examples of things you might find yourself working on.

Responsibilities

• Design and run experiments training robotics policies (imitation learning, reinforcement learning, VLA models, etc.) entirely or primarily in simulation.

• Work hands-on with physical robots (e.g. bimanual manipulator arms) to collect real-world data, validate sim-trained policies, and characterize the sim-to-real gap.

• Collaborate with our Dynamics team to identify simulation fidelity gaps that limit transfer performance, and help prioritize and validate fixes.

• Build and maintain data pipelines and evaluation frameworks/benchmarks for policy training and transfer performance.

• Prototype new tasks and domains (e.g. dexterous manipulation, cross-embodiment transfer), often grounded in real customer use cases, to expand what Zeromatter's platform can demonstrate.

• Read, evaluate, and adapt techniques from state-of-the‑art robot learning research for use on Zeromatter's platform.

• Contribute findings and results to customer‑facing technical materials and demonstrations.

• Build reusable libraries and tooling (in Python, Rust, and/or C++) to support this work at scale.

Qualifications

• You have an engineering or related technical degree (e.g. robotics, computer science, mechanical/electrical engineering, physics) or equivalent hands‑on experience.

• Experience training and evaluating robot learning policies (imitation learning, reinforcement learning, and/or foundation/VLA models) gained in industry, in a research lab, or through graduate/postdoctoral work.

• Hands‑on experience working with physical robots including collecting data, running experiments, and debugging real‑world hardware/software issues.

• Proficient in Python, Rust, and/or C++, with experience in ML frameworks such as PyTorch, TensorFlow, or JAX.

• Comfortable working with incomplete information, iterating quickly between simulation and real‑world validation.

• Familiarity with the practical challenges of sim‑to‑real transfer (e.g. domain randomization, system identification, observation/action space design, adaptation).

• Bonus: Experience with dexterous manipulation or other contact‑rich manipulation tasks.

• Bonus: Experience with cross‑embodiment policy learning or transfer across robot platforms.

• Bonus: Experience with teleoperation systems and data collection pipelines.

• Bonus: Experience working end-to-end across the robotics stack, including perception, classical and learned control systems, task planning, etc.

• Bonus: Familiarity with physics/dynamics simulation engines (e.g. MuJoCo, Isaac Sim, or custom/proprietary engines).

• Bonus: Publication record or open‑source contributions in robot learning, embodied AI, or manipulation.
