Autonomous Marine GNC Engineer

Crabi Robotics; Medford (MA); Hybrid; USD 110,000 - 170,000; Full time

Job summary

Crabi Robotics seeks a Robotics GNC Engineer to develop sensing, localization, and control software for an autonomous marine hull-cleaning robot. You will transform prototype data into robust, production-ready software, focusing on state estimation and sensor integration to enable reliable operation on moving vessels.

The role blends software with real-world hardware, requiring insights into sensor failure modes, real-time performance, and cross-disciplinary collaboration to deliver flight-ready

Qualifications

• Strong fundamentals in robotics, controls, state estimation, or autonomous systems.
• Proficiency developing software in C++ and/or Python.
• Hands‑on experience integrating physical sensors into robotic or autonomous systems.
• Experience with sensor characterization, data filtering, state estimation, or sensor fusion.
• Ability to analyze imperfect real-world sensor data and translate prototype algorithms into reliable software.
• Experience developing, testing, and debugging software that interacts directly with physical hardware.
• 1–7 years of relevant professional experience OR substantial graduate-level research or student engineering experience.

Responsibilities

• Develop and deploy localization, state estimation, navigation, and control software for an autonomous marine robot.
• Take new sensors from prototype data collection through characterization, filtering, fusion, integration, and production-ready software.
• Design algorithms that combine inertial, wheel odometry, vision, and other vehicle sensors to estimate robot state in challenging real-world environments.
• Develop simulation, Software-in-the-Loop (SIL), and Hardware-in-the-Loop (HIL) tests to validate GNC software before deployment.
• Define requirements, interfaces, failure modes, and performance metrics for vehicle sensors and GNC subsystems.
• Analyze real-world vehicle data to identify failure modes, improve algorithms, and close the loop between testing and software development.
• Design and execute system tuning, verification, and on-vehicle testing.
• Work closely with mechanical, electrical, firmware, and test engineers to integrate GNC software with vehicle hardware.
