Robotics Systems & Simulation Engineer

About the Role

As a Robotics Systems & Simulation Engineer at Xaira Therapeutics, you will connect digital environments with physical systems, making robotic capabilities easier to adapt to new equipment and settings. You will own the simulation and digital-twin infrastructure that enables the quick deployment of vision-guided robots to new instruments and serves as a testbed for robotics control, perception, and embodied AI. You will develop and validate integrated systems from prototype through real-world operation. This is a hands-on role spanning software, 3D geometry, simulation, and hardware.

Key Responsibilities

• Build integrated Real2Sim and Sim2Real workflows reusable across robotic platforms and laboratory environments.
• Create and validate digital twins from CAD, robot and sensor models, and reconstructed scenes, including coordinate alignment, articulation, and collision geometry.
• Connect simulation, perception, motion planning, and physical execution through the existing robot control stack, including robot state feedback and synchronization.
• Investigate discrepancies between simulated and measured behavior.
• Integrate AI models and task-level state machines with simulation and robotic tools, including structured requests, action validation, and execution feedback.
• Build synthetic-data and augmentation workflows, along with synchronized video and telemetry capture, replay, and evaluation tools.
• Benchmark system accuracy, reliability, latency, and GPU resource use; improve performance across local and cloud computing environments.
• Collaborate with software engineers on reusable configuration and operator tools; validate new installations and reduce manual setup effort.
• Work with scientists to integrate new capabilities, debug physical systems, and document architecture, experiments, and operating procedures.

Requirements & Tech Stack

• Strong software engineering skills in one or more languages such as Python, C++, or C#, with experience developing and debugging integrated applications in Linux.
• Hands-on experience building or extending robotics simulations or digital twins using Isaac Sim, MuJoCo, Gazebo, or comparable tools.
• Solid understanding of 3D coordinate transformations, robot kinematics, calibration, and the relationship between simulated models and physical systems.
• Experience integrating robots, sensors, or other physical systems through APIs, SDKs, ROS2, or comparable middleware.
• Familiarity with GPU computing and cloud-based workflows for simulation, AI, or data processing.
• Strong debugging and experimental skills, clear technical communication, and the ability to learn unfamiliar methods while critically validating software and AI-generated outputs.

Qualifications

• Bachelor's, Master's, or PhD in Computer Science, Robotics, Electrical Engineering, Mechanical Engineering, or a related field. Recent graduates with substantial relevant research or project experience are encouraged to apply.

Preferred Qualifications

• Experience with 3D reconstruction, CAD/robot-model pipelines, RGB-D perception, multi-view fusion, or learned scene representations.
• Experience integrating LLMs, vision-language models, AI agents, or Model Context Protocol (MCP) servers with external tools and physical systems.
• Experience with spatial or object reasoning, active perception, or perception of transparent, reflective, or partially occluded objects.
• Experience with video understanding, human-object interaction, learning from demonstrations, imitation learning, or other robot-learning methods.
• Experience with GPU profiling, CUDA programming, accelerated inference, or edge deployment.
• Experience with 6-axis robotic arms, mobile robots, laboratory instruments, or hands-on mechanical prototyping.
• Experience mentoring students, interns, or junior engineers.
