Embedded Software Engineer

Company Details

We are on a mission to build the Internet in Space

Kepler is on a Mission to bring the internet to space. Incorporated in 2015, Kepler’s guiding star is to enable the space economy through the creation of a communication network in Low Earth Orbit (LEO) that will provide connectivity services to other space missions, be they on orbit in LEO, MEO, GEO, or beyond.  With an expanding base of early customers and our first 19 satellites in orbit, Kepler is continuing to grow and expand its most important asset – the Team! Based out of our HQ in Toronto and with an office in the UK and a newly formed office in the US we are building towards a truly global company delivering a product for the whole world.
