Charge Robotics is a Series A startup building robots that build solar farms.

Demand for new solar projects is booming (1 ⁄ 5 of all the solar that exists in the US was installed last year!), but today's construction companies can't keep up due to limited labor resources.

We thought this was insane, so we started working on robots to directly address this bottleneck and speed up the world's transition to renewables.

Charge is a fast-moving company, which means constant opportunities for learning and growth. You'll have a large impact on the direction of our company, and will be compensated accordingly.

We're MIT-founded and backed by top generalist and climate tech investors, including Founders Fund, Energy Impact Partners, Lux Capital and Y Combinator (S21).

If you're excited to work on interesting problems with direct climate impact, you're going to fit right in! Read more about Charge at the links below:

About this role

As a Senior Robotics Software Engineer at Charge Robotics, you'll be working full-stack and playing a direct role in deploying gigawatts of clean power generation.

What you'll be working on

  • Architecting, building, documenting, testing, and iterating on software for our robotic factory installation system
  • Developing perception, motion planning, and controls software that lets our robots operate reliably in unstructured field conditions.
  • Contributing to low-level software powering robotic systems in our factories and delivery vehicles, with emphasis on correctness and safety
  • Controlling industrial automation hardware including linear actuators, motors, and hydraulic systems

You

  • Are an experienced Python developer and comfortable with at least one lower-level language like C++, with experience writing real-time, embedded, or robotics software
  • Know how to instrument and develop highly performant software as a member of a team, including writing clean code, documenting it, testing it, and using version control and CI
  • Have worked in a fast-paced startup environment before, and loved it
  • Are excited to work with (and occasionally safely climb into) giant robots
  • Have excellent written and verbal communication skills
  • Are based in or can relocate to the SF Bay Area, and able to work 4-5 days/week from our San Leandro HQ
  • Are open to ~10% travel to field (solar construction sites) to work directly with our product in its deployment environment
  • Are excited to see your work deployed onto actual solar farms!

It'd also be nice if you

  • Have experience working with industrial robot arms, motion planning, or automation systems
  • Have a 4-year degree in computer science, robotics, or a related field
  • Gain satisfaction from personally playing a part in mitigating climate change

About Charge Robotics

Company Overview

Name

Charge Robotics, a private robotics startup

Headquarters

Oakland, CA, United States

Founded

2021

Size

Approximately 10-50 employees (source: pitchbook.com)

What They Do

Charge Robotics specializes in automating the most labor-intensive aspects of solar farm construction, focusing primarily on the assembly and installation of solar farm structures (source: linkedin.com). The company describes itself as "the assembly line for solar," providing a turnkey crew and factory system that takes a solar site from pile driving to mechanical completion by automating structural assembly from factory loading through row installation and quality assurance handoff (source: chargerobotics.com). Their technology employs a portable robotic assembly-line approach that integrates panels, steel tracks, fasteners, and mounting hardware into completed solar sections ready for transport and installation on-site (source: startupintros.com). This approach aims to reduce labor bottlenecks and accelerate deployment timelines for utility-scale and commercial solar projects (source: pitchbook.com). Charge Robotics targets solar EPCs, construction contractors, and large-scale solar developers seeking faster site execution and scalable installation capacity, differentiating itself through a combination of robotics and a factory-like field deployment model rather than automating isolated tasks (source: chargerobotics.com).

Projects & Track Record

Charge Robotics has publicly referenced an advanced prototype deployment in partnership with SOLV Energy, one of the largest solar installers in the United States, to build a solar facility using their robotic assembly system (source: startupintros.com). This prototype system demonstrates their capability to automate solar-facility construction, although detailed public information on completed projects, capacities, or site-specific specifications remains limited. The company’s geographic footprint is primarily centered in the San Francisco Bay Area, with confirmed locations in Oakland and San Leandro, California, which serve as the core hubs for their operations and development (source: sec.gov). Additional office locations have been listed in Norwich, United Kingdom, and Delray Beach, Florida, but the strongest corroboration supports the Bay Area as their main base (source: exa.ai).

Recent Developments

In August 2024, Charge Robotics completed a significant Series A1 funding round, raising $17 million and marking a transition into a revenue-generating stage (source: pitchbook.com). SEC Form D filings confirm this incremental cash infusion of $16,999,997, underscoring investor confidence in the company’s growth trajectory (source: sec.gov). Throughout 2026, Charge Robotics has actively recruited senior robotics software engineers and mechanical engineers, signaling ongoing product development and scaling efforts to enhance their electromechanical factory and robotic fleet capabilities (source: linkedin.com).

Working There

Charge Robotics offers roles primarily in robotics software engineering and mechanical engineering, with mechanical engineers playing a critical role in designing, diagnosing, and improving assemblies for the company’s electromechanical factory and delivery vehicle fleet (source: linkedin.com). The company culture is described as a team of engineers, builders, and problem solvers dedicated to bringing automation to solar construction sites (source: chargerobotics.com). Active hiring infrastructure is evident in the Bay Area, particularly San Leandro, where recruiting efforts include founding recruiter roles (source: linkedin.com). Compensation for senior robotics software engineers ranges from $175,000 to $200,000, while mechanical engineers earn between $130,000 and $190,000, reflecting competitive pay scales for specialized technical roles (source: linkedin.com).
