Ask HN: Who is hiring? (February 2022)

We are a team of engineers and energy experts working on getting our customers paid for using less energy. Our customers are energy consumers (factories, skyscrapers, warehouses, steel mills...) who will commit to curtailing their demand on a signal from us. We aggregate those "curtailable" buildings into virtual power plants that we sell to utilities and other buyers in wholesale energy markets, splitting the revenue with our customers. Our virtual power plants are cleaner and cheaper than the coal and oil plants they replace.

Along the way, we have to solve some complex problems:

  - trade energy in an international patchwork of wholesale power markets
  - convince a wide variety of factory supervisors and building managers to cease their operations when they would rather not
  - make hundreds of commercial and industrial buildings behave like a single, reliable generator in every way

We’re working with space lasers, going to the moon, rendezvousing with other spacecraft, and more. As a company, we’re designing and manufacturing satellites at a rapid pace – our average mission goes from concept to launch in 1-2 years. Our small team writes all the onboard software as well as the ground software which controls and monitors them, but you don’t need a physics degree or aerospace experience to work here! We’re looking for smart people who would love to work in the space industry, especially those who never thought they’d be qualified for a space job or didn’t want to work for a giant aerospace corporation or government agency.

  - Senior/Lead Web Software Developer
  - Senior/Lead Embedded Software Developer
  - Site Reliability Engineer
  - Product Designer
  - Product Manager
  - Director of Software
