Requirements
  • Experience developing in Python and comfort with at least one lower-level language such as C++, with experience writing real-time, embedded, or robotics software.
  • Experience instrumenting and developing highly performant software, writing clean code, documenting it, testing it, and using version control and continuous integration.
  • Previous experience working in a fast-paced startup environment.
  • Excellent written and verbal communication skills.
  • Residence in or willingness to relocate to the San Francisco Bay Area.
  • Ability to work 4–5 days per week from the San Leandro headquarters.
  • Willingness to travel approximately 10% to solar construction sites and work directly with the deployed product.
Responsibilities
  • Architect, build, document, test, and iterate on software for the robotic factory installation system.
  • Develop perception, motion planning, and controls software that enables robots to operate reliably in unstructured field conditions.
  • Contribute to low-level software powering robotic systems in factories and delivery vehicles, with emphasis on correctness and safety.
  • Control industrial automation hardware, including linear actuators, motors, and hydraulic systems.
Desired Qualifications
  • Experience working with industrial robot arms, motion planning, or automation systems.
  • A 4-year degree in Computer Science, Robotics, or a related field.

Charge Robotics builds robotic systems that automate solar installation work to remove labor bottlenecks in construction. Their robots handle tasks in the field to speed up the process of deploying solar projects, allowing construction teams to install more systems in less time. This focus on automation of on-site installation differentiates Charge Robotics from competitors that only provide components or software rather than end-to-end robotic labor solutions. The company’s goal is to help the world switch to renewable energy faster by making solar installation scalable and more efficient.

Simplify Jobs

Simplify's Take

What believers are saying

  • Sunrise installs 1 megawatt daily, matching 80 workers' output, accelerating utility-scale solar farm deployment
  • Mobile factories operate 24/7 and run multiple units simultaneously, completing projects faster without expanding workforce
  • Adaptable across diverse terrains and compatible with common solar parts, enabling deployment in varied global locations

What critics are saying

  • SOLV Energy may scale proprietary automation or partner with KUKA/ABB within 12–18 months, eliminating Charge as vendor
  • Y Combinator peers pivoting industrial humanoids to solar racking assembly within 18–24 months could outperform rigid track system
  • Charge's $39.1M funding cushion may run dry in 12–18 months before achieving positive unit economics due to supply delays

What makes Charge Robotics unique

  • Sunrise is the world's first fully automated solar construction system assembling 40-foot, 800-pound bays
  • Portable factory deploys from a truck with no fixed infrastructure, assembling steel tracks and panels autonomously
  • Real-time AI computer vision verifies every fastener and panel position, ensuring quality without human labor on line

Charge Robotics raises $22M to automate utility-scale solar farm construction

Charge Robotics, founded by MIT alumni Banks Hunter and Max Justicz, has raised $22 million to deploy its portable robotic factories for utility-scale solar farm assembly. The company plans to begin commercial installations later in 2025. The factories automate solar panel installation, which currently relies on manual labour. In early 2024, Charge deployed a prototype system with SOLV Energy, successfully building a working solar farm. The system works like a portable assembly line. Steel tracks, mounting brackets, and panels are loaded in, and the factory robotically assembles them into 40-foot sections. A robotic vehicle positions each completed bay in the field. Solar accounted for 81% of new US electric capacity added in 2024, but labour shortages constrain growth. Charge's system allows multiple factories to run simultaneously at sites, completing projects faster without expanding the workforce.
