AP110 Principal Software Systems Engineer / Full-Stack Architect

Program: NASA GSFC Astrophysics Science Division: Guest Observer Facility (GOF) Modernization Project Location: Remote Position, US-based only (occasional travel to NASA Goddard Space Flight Center, Greenbelt, MD will be required for badging and review milestones) Employment Type: Full-time contractor position Level: Senior / Principal (~10+ years of relevant experience) Eligibility: Must be a US Citizen or Lawful Permanent Resident (LPR); having resided in the US for the past 3 consecutive years and able to meet the access requirements for a system handling Controlled Unclassified Information (CUI) and Personally Identifiable Information (PII). About the Project: The NASA Astrophysics Science Division operates a set of ongoing space-based observatories and manages the Science Operations of these missions. Key among those responsibilities are the Guest Observer Facilities (GOFs) for each mission which enable the astrophysics community to propose new research for these missions. These Guest Observers are supported through a process that manages the proposal, peer-review, and grant-initiation lifecycle for multiple astrophysics missions including NuSTAR, NICER, XRISM, IXPE, TESS, XMM, Fermi and Swift. The GOF Modernization Project will design and deliver a unified, multi-mission software system that streamlines the full proposal, review, grant workflow: proposal submission, reviewer recruitment and expertise matching, conflict detection, panel definition, evaluation, programmatic decisions, document and report generation, and grants-package preparation. The system must serve many distinct user types (GOF leads and staff, Principal Investigators, proposers, reviewers, reviewer selectors, award recipients, and NASA Headquarters) each with tailored interfaces and responsibilities. The system must secure sensitive (CUI), multi-mission databases deployed in th
