As the SV Responsible Systems Engineer (RSE) within the SEIT team, you will oversee satellite bus and payload integration, development, and delivery for the Space Development Agency's Proliferated Warfighter Space Architecture (PWSA) Tranche 2 Transport Layer. This role requires technical leadership in satellite systems design, qualification, and deployment to enable advanced missile tracking capabilities using infrared sensors on a constellation of 18 space vehicles operating in Low Earth Orbit. The lead will coordinate multi-disciplinary teams, ensure interoperability across the PWSA layers, and support satellite production timelines to meet launch and operational milestones. One of the primary deliverables will be the SV Certification (verifying the SV and all of its subsystems are ready to launch)., Performs technical planning, system integration, verification and validation, cost and risk, and supportability and effectiveness analyses for total systems. Analyses are performed at all levels of total system product to include: concept, design, fabrication, test, installation, operation, maintenance and disposal. Ensures the logical and systematic conversion of customer or product requirements into total systems solutions that acknowledge technical, schedule, and cost constraints. Performs functional analysis, timeline analysis, detail trade studies, requirements allocation and interface definition studies to translate customer requirements into hardware and software specifications. ## Related Videos - [Robots are coming into the wild!
