As NASA's largest engineering solutions provider working together with NASA at centers across the United States.

We have an exciting opportunity for a remote part-time Orion Passive Thermal Control System (PTCS) Subject Matter Expert to join the JETSII Contract.

Amentum is seeking an experienced Orion Passive Thermal Control System (PTCS) Subject Matter Expert to support development, integration, verification, and operations for NASA's Orion spacecraft and Artemis missions. This role provides specialized technical insight into spacecraft thermal behavior, supports integration coordination across multiple subsystems, and contributes to mission planning, activation, testing, and real‑time operations. The PTCS SME works directly with NASA customers, design teams, and mission operations personnel to ensure safe and reliable thermal performance for human‑rated spacecraft.

This position will specifically serve as the in-house expert on the Orion heater system architecture.

Responsibilities include:

* Serve as the Orion PTCS Subject Matter Expert, supporting thermal behavior assessment, operations development, engineering evaluations, flight rule inputs, and integrated analysis. Act as the primary technical authority on the Orion heater system, supporting training teams and resolving heater related technical issues.

* Review subsystem requirements, design changes, and analysis products to ensure proper integration across thermal, electrical, mechanical, and avionics systems.

* Support development of mission operations products, activation timelines, and procedures related to thermal system behavior.

* Participate in integrated simulations and real‑time mission operations providing assessments of subsystem performance.

* Support anomaly resolution, system troubleshooting, and risk evaluations for PTCS‑related issues. Lead investigations and resolution efforts for heater system anomalies and performance concerns.

* Provide inputs to flight rules, operations concepts, displays, controls, and operations documentation involving thermal systems.

* Collaborate with NASA engineering and operations teams to support technical decision‑making, verification planning, and mission readiness activities.

* Provide mentorship, technical guidance, and subsystem leadership within multi‑disciplinary teams.
