Spire’s Space Services API team develops the interfaces used by our customers to design, test, deploy and operate space-based software applications. In some cases, these applications run on standard Spire hardware, and in some cases on hosted payloads custom-designed by us or our customers. As a senior software engineer on the Space Services APIs team, you’ll help develop and maintain our customer facing APIs both on the satellite and on the ground. This currently includes interfacing with our disruption tolerant networking stack for both space to ground and inter-satellite links, our satellite bus and ground services that allow customers to task their satellite payloads and upload code and configuration. You’ll also help drive the product forward by developing new features and services to help customers more easily onboard onto the service, scale their payload constellation and drive operational excellence. You will interface with the product function and our technical program managers to develop elegant technical solutions to customer needs, together with a team of developers distributed between Europe and the US. Key engineering partners include the Satellite Control Systems, Constellation Scheduling, Platform Software, Systems Engineering and program managers. You will be part of a nimble and autonomous team yet have access to resources of the rest of Spire’s 200 person engineering organization including SREs, security engineers, and infrastructure tooling.
