Job description

A thriving economy in space is needed to make life on Earth more vibrant, sustainable, and equitable. Space technology will enable global access to information, solutions to climate change, answers to global food security, products that transform healthcare, clean energy production, and more. Today, rocket launch options are slow, expensive, and unreliable. Stoke is building the world’s most efficient fully and rapidly reusable rocket designed to fly daily that will radically increase access to space and open up the space economy to safeguard our precious home, Earth.

Description

The avionics system is the backbone of highly reusable, operable, and reliable space systems. As the battery engineer at an early-stage start-up you will be responsible for owning the entire battery system. You will work closely with the rest of the development team and other stakeholders to design and implement the battery architecture, procure cells and other components, develop custom hardware, define and perform component and system-level tests, integrate the battery system into the rocket, and continuously iterate and improve your designs. You will seek out state-of-the-art solutions to difficult problems and you will assist in the definition of company standards for avionics development. You must be ready to stay focused, move fast, self-direct, and learn on the fly.
