Square One Resources is hiring for a robotics team focused on autonomous vehicle platforms migrating from ROS 1 to ROS 2, working on Unmanned Ground Vehicle (UGV) systems including navigation, localization, and vehicle control.

• Commercial experience with ROS, preferably both ROS 1 and ROS 2.
• Practical development experience with C++ and/or Python.
• Good understanding of core ROS concepts including nodes, topics, services, actions, TF, and parameters.
• Basic to intermediate practical experience with ROS 2.
• Familiarity with Nav2 or other ROS-based navigation frameworks.
• Familiarity with ros2_control / ros_control.
• Basic understanding of DDS and QoS concepts.
• Experience working with Linux environments.
• Experience with robotics, autonomous systems, or mobile robotic platforms.
• Experience with sensors such as GNSS, IMU, CAN, and odometry is advantageous.
• Familiarity with robot_localization, BehaviorTree.CPP, Foxglove, or sensor fusion is advantageous.
• Ability to troubleshoot complex software and communication issues in distributed robotic systems.
• Good English communication skills.

• Migrate existing ROS 1 nodes and packages to ROS 2.
• Analyze ROS 1 topics, services, actions, parameters, launch files, TF trees, and dependencies.
• Adapt existing C++ and Python code to ROS 2 APIs and architecture.
• Support migration and configuration of components based on ros2_control / ros_control.
• Support navigation migration and configuration using Nav2.
• Work with existing BehaviorTree.CPP based functionality.
• Support localization based on robot_localization, GNSS, IMU, and odometry.
• Integrate and test GNSS, CAN, IMU, odometry, and other sensor inputs.
• Support sensor fusion and localization pipelines.
• Assist with vehicle control and actuation interfaces including braking and steering.
• Configure and troubleshoot DDS/QoS communication.
• Investigate timing, synchronization, latency, and communication issues.
• Perform regression testing using recorded data, logs, and repeatable test scenarios.
• Use tools such as Foxglove for visualization, debugging, and system analysis.
• Participate in integration testing in simulation, bench environments, and physical vehicles.
• Document implemented changes, dependencies, and identified technical issues.
• Collaborate with Senior and Lead Engineers and the customer's robotics team.
