Senior Guidance, Navigation, and Control (GNC) Engineer About Us: BlackSky BlackSky is a real-time intelligence company. We own and operate the world's most advanced space-based intelligence platform and provide customers satellite imagery, automated analytics and high-frequency monitoring of strategic locations, economic assets, and events from around the globe. BlackSky is trusted by the most demanding allied military and intelligence organizations and commercial companies to deliver foresight into critical matters that affect national security and the economy.

BlackSky's data enables governments and businesses to see, understand and anticipate change as it happens, giving them the ultimate strategic advantage so they can act quickly. Our global team works with cutting-edge technology to make a difference around the world and prides itself on being people-first, customer-focused and fun. As a Senior GNC Engineer at BlackSky, you will be a key contributor to the development, production, and operation of high-performance Guidance, Navigation, and Control (GNC) / Attitude Determination and Control (ADC) systems for satellite constellations.

You will perform trade studies, simulations, and other analyses to support end-to-end ADCS design, development, and verification. You will work closely with software developers to integrate ADCS components into flight software. You will define test plans and procedures in support of satellite production and verify satellite flightworthiness.

You will work closely with satellite operators to characterize and improve on-orbit ADCS performance. You will do all this while collaborating with a fast-paced, highly skilled technical team focused on producing state-of-the-art satellites. This role will be a hybrid role based out of Tukwila, WA and will report to the GNC Engineering Manager.
