Gravitics is enabling space stations without compromise, beginning with our giant StarMax orbital habitat. One StarMax module will add roughly half of the existing International Space Station’s habitable volume – in a single launch! We’ll be spooling up from there and we could use your help.
We have aspirational sights, pragmatic footsteps, a proven team who executes, and committed funding. Join us!
About the Role:
To build our giant space systems, we need a rockstar who can directly work the full product lifecycle of challenging avionics systems, including computers, photovoltaics, batteries, harnessing, and more. Responsibilities:
· Challenge the status quo.
· Add your voice to find a better solution.
· Own your system and own it.
· Identify requirements and invent hardware that meets them
· Design and build efficient and reliable power electronics from whiteboard sketch to gerber files.
· Bring up and checkout hardware rapidly in a scrappy environment
· Work with suppliers and our manufacturing team to make your designs reality.
· Be a reliable expert of your system, from concept to mission control console.
Do the responsibilities look vague? You bet they do. Come if you thrive in challenging projects with freedom to shape ambiguity into better solutions.
You’re a successful candidate if you are a giver, not a taker. You have an ability to make things happen. You are exceptional at several things, yet willing to take on efforts in areas of weakness. You don’t even know what “comfort zone” means.
