Job Description
ATMOS Space Cargo is seeking a Thermal Engineer (m/f/d) to support the thermal design, analysis, and verification of our re-entry and return vehicle technologies. In this role, you will work closely with multidisciplinary engineering teams to ensure our spacecraft hardware performs reliably across mission phases, from launch and orbit operations to re-entry and landing.
- You will develop and maintain thermal models for spacecraft level thermal architecture, including active and passive thermal control design for avionic components and payloads.
- You will perform thermal modeling across mission phases, including launch, orbit operations, de-orbit, re-entry, landing, and ground handling.
- You will design, analyze, and integrate pumped fluid loops to manage heat collection and rejection for spacecraft survival in extreme orbital environments.
- You will select and optimize COTS fans to maximize forced-air cooling efficiency while minimizing acoustic signatures and meeting outgassing standards for microgravity locker environments.
- You will perform transient thermal analysis of spacecraft thrusters, including heat soak-back assessment, propulsion thermal modeling, and cross-functional coordination with propulsion, mechanical, and systems engineering teams.
- You will define and manage flight hardware interfaces during integration, including pipes, fittings, valves, MLI, heaters, sensors, harness routing, thermal fillers, and related components.
- You will design and plan thermal test campaigns, including Active Thermal Control System (ACTS), TVAC, thermal balance, and thermal cycling, at system and sub-system level.
- You will work closely with mechanical, systems, avionics, and AIT teams to ensure technical alignment across subsystems and interfaces.
- You will prepare and maintain thermal engineering documentation, including analysis reports, test procedures, verification plans, and review inputs.
