Position Summary

Reporting directly to the VP of Manufacturing & Product Development at our Chandler R&D facility, you will design and implement the software architecture for an autonomous robotics system that integrates computer vision, real-time computing, artificial intelligence, and industrial controls into a unified platform. As our Lead Robotics Software Engineer, you will develop mission-critical software to continually enhance and enable the guidance, navigation, and full automation systems of our solar panel cleaning robot. You will work closely with a cross-functional team of software, electrical, and mechanical engineers to define requirements, implement solutions, test, and debug software to ensure a highly reliable and scalable system. This role also includes driving best practices in software engineering, mentoring team members, and contributing to a repeatable, systematic, and data-driven development process.

LOCATION NOTE: Although this hybrid role offers partial work-from-home flexibility, candidates must reside within the Phoenix or Tucson metropolitan areas to participate in on-site, hands-on testing at our Chandler, AZ R&D facility and Mesa, AZ test site.

What You’ll Be Doing

- Collaborate within a cross-functional engineering team in a fast-paced, start-up-like environment.

- Design, develop, and maintain robotics software systems from concept through production, applying real-time computing principles.

- Implement robotic perception, motion planning, path planning algorithms, and control systems to achieve fully autonomous outdoor operation.

- Develop and integrate ROS/ROS2-based modules for navigation, obstacle avoidance, and precise robotic actuation.

- Utilize computer vision algorithms, sensor fusion techniques, and data-driven performance improvements.

- Optimize software for efficiency, memory usage, and reliability across varying field conditions.

- Build simulation environments (Gazebo, RViz) to test and validate algorithms prior to field deployment.

- Conduct field trials at solar power plants to test, debug, and refine software for real-world performance.

- Lead software engineering best practices, including CI/CD, version control, code reviews, and documentation.

- Create and maintain technical documentation, system design specifications, and user guides.

- Mentor junior developers and promote continuous improvement in processes and development standards.

- Apply Agile methodologies to manage sprints, features, and backlog effectively.

- Occasionally travel to deployment sites for testing and system validation.

Desired Qualifications:

- Strong collaborative mindset with a team-first approach and ability to thrive in a start-up culture.

- Proven ability to deliver high-quality, robust, and efficient software for real-world environments.

- 5+ years of experience in robotics, embedded systems, or autonomous platforms. - Proficiency in C++, Python, and familiarity with JavaScript, and ROS2. - Hands-on experience with Linux-based systems (5+ years).

- Knowledge of industrial controls, networking protocols (CAN, Serial, USB, Ethernet)

- Experience developing and optimizing motion planning, path planning, and computer vision algorithms.

- Strong understanding of sensor integration and sensor data handling.

- Familiarity with AI algorithms and autonomous navigation techniques.

- Experience with CI/CD tools, source control (Git, SVN), and software verification/validation processes.

- Skilled in technical documentation and system design specifications.

- Strong problem-solving and technical troubleshooting abilities.

- Excellent written and verbal communication skills.

- Self-motivated, detail-oriented, and passionate about continuous improvement.

- Hands-on experience with electronics lab tools (oscilloscope, multimeter).

- Willingness to travel for field testing and deployment as required.

Desired Education and Technical Knowledge

- Bachelor’s degree in Computer Science, Software Engineering, Robotics, or a related field (Master’s preferred).

- 7+ years of software development experience in robotics or embedded systems. - 3+ years of experience developing in C/C++, plus strong experience in Linux environments.

Bonus Points For:

- Prior experience with mobile robotics or autonomous vehicle software.

- Expertise in AI/ML for robotics (perception, decision-making).

- Familiarity with systems engineering and requirements methodologies.

- Knowledge of safety-critical software development standards

Compensation and Benefits
