About Charge Robotics:

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:

Mechanical Engineers are the heart of the Charge team — designing, diagnosing, and improving critical assemblies our large electromechanical factory and fleet of delivery vehicles.

What you’ll be working on:

  • Designing, building, testing, and iterating on mechanical systems for solar assembly

  • Tracking, investigating, and resolving hardware issues with robots

  • Communicating with other engineers to integrate new designs

  • Playing with some very large mechanisms

You:

  • Are experienced with industry-standard CAD software (we use Onshape)

  • Know how to fabricate your parts but also know when to send drawings out to a shop

  • Enjoy working in a fast-paced startup environment

  • Have excellent written communication skills

  • Gain satisfaction from personally playing a part in mitigating climate change

  • 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 10-15% travel to field (solar construction sites) to work directly with our product in its deployment environment

  • Are excited to see our robots deployed onto actual solar farms!

It’d also be nice if you:

  • Have experience working with industrial robot arms, end effectors, and automation systems

  • Have a 4-year degree in mechanical engineering or a related field

Charge Robotics

We build robots that build solar farms.

Charge Robotics is building robots that automate the most labor-intensive parts of solar construction. Solar has rapidly become the cheapest form of power generation in many regions, and demand is skyrocketing (one fifth of all the solar in the US today was installed last year!) but today's construction companies can't find the labor to build in these remote areas under extreme heat, dust, and wind. Our robots make it cheaper, faster, and safer to build utility-scale solar farms, allowing construction companies to meet the rising demand for solar and enabling the world to switch to renewables faster. We’re MIT-founded and based in the East Bay, backed by some of Silicon Valley’s top investors - including Founders Fund, EIP, and Y Combinator (S21).
