Robotics Engineer

Robotics Engineer (Remote, Full-Time) Rex.zone is hiring a mid-senior Robotics Engineer to build, implement, and evaluate real-world autonomy workflows across perception, planning, and control. This role blends robotics software engineering with rigorous dataset creation, QA evaluation, prompt evaluation, and safety-focused validation to improve ML-driven robotics reliability.

Key Responsibilities

• Own robotics perception, planning, and control modules with measurable reliability targets
• Build simulation-to-real evaluation workflows using logs/bags and scenario replays
• Define and enforce annotation guidelines and labeling taxonomies for vision/sensor/task data
• Perform QA evaluation of labeled datasets and model outputs; drive training data quality improvements
• Run prompt evaluation for instruction-following and operator tooling used in robotics workflows
• Support RLHF-style preference data collection for behavior selection and safety constraints when applicable
• Conduct error analysis, regression testing, and benchmark reporting
• Collaborate cross-functionally to align priorities, acceptance criteria, and deployment readiness

Required Qualifications

• Mid-senior experience building robotics systems in production or advanced R&D
• Strong Python and C++ skills; comfortable with ROS2-based development
• Hands-on knowledge of robot perception, computer vision, SLAM, and sensor fusion
• Experience with motion planning and control systems, including real-world debugging
• Familiarity with dataset creation, data labeling workflows, and training data quality principles
• Ability to write clear documentation, labeling specs, and test plans

Preferred Qualifications

• Experience with Gazebo/Ignition (or similar) simulation and autonomy evaluation
• Exposure to LLM-assisted robotics tooling, prompt evaluation, and safety review
• Familiarity with RLHF concepts and human-in-the-loop evaluation

Compensation Competitive hourly rate: $30–$50/hr (USD).
