Senior Communications Engineer, Space Vehicle About Us: 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. BlackSky is looking for an engineer with a strong background in RF communications to be a part of a multi-disciplinary team in the development of satellite communication systems. As part of the Communications Engineering team, you will be instrumental in engineering design, production and testing of our communication systems on our next gen satellites along with ground station compatibility. While primarily focused on spacecraft communications, you'll be involved throughout the engineering lifecycle through design, integration, test, and ultimately the operation of satellites. This position is ideal for a candidate who possesses the eagerness and aptitude to adapt and extend traditional systems engineering and spacecraft development practices to an agile and low-cost environment. You will be engaged in all aspects of satellite system and subsystem electrical design and test, with a focus on RF networks and satellite communication systems. You will use your understanding of electrical and RF communications principles and concepts to support the design and development of satellites through all phases of the product lifecycle. You'll work directly with technical leadership and other members of a multi-disciplined team to develop and test microsatellite communications systems. You will architect and execute test plans to show functionality of these systems. Furthermore, you will also be responsible for interfacing with ground station providers and satellite end users to ensure system compatibility. This role will be based out of Tukwila, WA and will report to the Director of Ground and Communication Systems. Responsibilities: As a member of the satellite communications system, you will be involved with performing communications system design and analysis, testing, debug, data analysis, and supporting flight hardware design. Perform functional analyses (link, power, throughput, etc.), detailed trade studies, and interface definition efforts to translate initial requirements into concepts and eventually detailed and qualified designs. Identify the necessary space-segment and ground-segment hardware necessary to accomplish payload and telemetry transmission over a wide range of mission CONOPS and orbital parameters. Create dedicated test setups, procedures for antenna checkout, radio peripheral checkout, cable/phasing network checkout, ground station compatibility tests, channel simulation tests, regulatory tests, and end to end full RF systems tests. Work hands-on with digital and analog RF equipment including radios, antennas, ADCs, and ground support equipment. Support production testers in the development and execution of test plans that ensure adequate testing of units and the complete system. Interface with supplier/vendors as needed to support subsystem procurement, design, development, and production. Collaborate among a multi-disciplinary engineering and production team to design and test satellite systems, subsystems, and components Support analyses and troubleshooting of in-orbit communic
