About the job

Requirements
  • A Bachelor's degree in Mechanical or Aerospace Engineering with a thermal or cryogenics focus, or a related technical discipline, and typically at least 12 years of related experience; alternatively, a Master's degree in a similar discipline and at least 10 years of experience; or a PhD degree in a similar discipline and at least 8 years of experience.
  • Broad knowledge and experience in one or more of cryogenics, heat transfer, fluid mechanics, thermal systems design, controls theory, and systems engineering.
  • Significant experience in spaceflight thermal subsystem or instrument engineering, particularly spacecraft thermal bus design and development.
  • Thermal hardware delivery experience.
  • Experience leading teams and coordinating project working groups in instrument, subsystem, or bus development, testing, or operations at the systems level.
  • Experience developing and delivering system documentation, including requirements documents, test plans, interface agreements, and design description documents.
  • Experience working on external procurements.
  • Experience in requirements and interface development, systems formulation, verification, and flight operations.
  • Ability to manage multiple issues, tasks, and priorities concurrently.
  • Willingness to support frequent domestic travel.
Responsibilities
  • Serve as the JPL systems engineer responsible for overseeing specification, implementation, verification, and validation of a flight system or payload thermal control system, reporting programmatically to project payload and flight system managers and administratively to the Thermal, Propulsion & Materials Engineering Section Manager.
  • Remain cognizant of the technical design, status, and issues of a flight system or payload thermal control system throughout development Phases A through D; ensure thermal products and processes meet JPL institutional standards and document non-compliances.
  • Plan, direct, and control financial and labor resources and schedules; make risk management decisions and performance commitments to fulfill project objectives.
  • Manage flight system or payload thermal risks.
  • Provide thermal technical leadership individually or as a member of a management team.
  • Oversee development of flight system or payload thermal interfaces, coordinating stakeholders to ensure operable, reliable, and safe interactions between systems.
  • Present work in management and project reviews as required.
  • Represent the flight system or payload thermal system at systems engineering team meetings, leading and contributing to design trades at the project system level.
Desired Qualifications
  • Experience implementing a thermal control system with an external partner.
  • In-depth knowledge of translating spacecraft or instrument requirements into thermal requirements.
  • Experience designing and implementing cryogenic (sub-4K) flight hardware and operating cryogenic instruments.
  • Familiarity with cryogenic instrumentation.
  • Experience with thermal control of flight systems or space-based instruments.
  • Experience planning, preparing, and executing flight thermal balance tests.
  • Knowledge of JPL and NASA policies and procedures.
  • Experience developing flight project and/or technology development proposals.
  • Working knowledge of thermal environments for flight system or instrument development.
  • Thermal software experience with Thermal Desktop and mechanical computer-aided design software experience with Solidworks, AutoCAD, and NX.
  • Experience writing procedures, releasing drawings, and negotiating and implementing cross-domain interfaces involving manufacturing, structural analysis, electrical, fault protection behaviors, flight rules, and outside vendors or collaborators.

NASA Jet Propulsion Laboratory

View

NASA Jet Propulsion Laboratory (JPL) is a federal research center managed by Caltech for NASA. It designs, builds, and operates robotic space missions for planetary exploration, Earth science, and space-based astronomy, along with technology development. JPL translates scientific ideas into real missions using specialized engineering, software, and mission operations conducted by cross-disciplinary teams, often in collaboration with NASA centers and other partners. Unlike many contractors, JPL functions as a government-run R&D center that directly plans and executes missions from concept through flight operations, ensuring national-space capabilities and scientific discovery stay aligned with NASA's goals. The lab’s aim is to turn bold science questions into working space missions and technologies that advance our understanding of the solar system and Earth, while upholding values of being bold, inclusive, and trusted.

Simplify's Take

What believers are saying

  • Congress funded NASA at $24.4 billion on January 16, 2026, stabilizing JPL.
  • FAME demonstrations started June 2026, targeting near-real-time wildfire and flood alerts.
  • JPL still manages dozens of missions, preserving customer trust and technical relevance.

What critics are saying

  • JPL cut 550 jobs in October 2025 after earlier 2024-2025 layoffs.
  • Mars Sample Return cancellation erased JPL's flagship program and funding base.
  • Persistent budget cuts and telework exodus threaten JPL's Caltech-managed lab model.

What makes NASA Jet Propulsion Laboratory unique

  • JPL runs more than three dozen flying missions across Earth science and planetary exploration.
  • Loft Orbital's June 23, 2026 partnership puts JPL AI on orbit.
  • Howard Eisen and Keyur Patel anchor mission success and chief-engineering discipline.

Loft Orbital to deploy NASA JPL's AI software for real-time Earth disaster monitoring

Loft Orbital has secured an agreement with NASA's Jet Propulsion Laboratory to host and demonstrate AI software on its space infrastructure. The collaboration, part of JPL's Federated Autonomous MEasurement project funded by NASA's Earth Science Technology Office, will advance on-orbit AI capabilities for Earth science remote sensing. Flight demonstrations began in June 2026, with additional deployments scheduled through 2028. JPL's AI software aims to reduce data latency by processing information in near-real time, delivering urgent insights on wildfires, flooding and natural disasters to emergency responders. The spacecraft will demonstrate autonomous tip-and-queue tasking without ground intervention using intersatellite links. Founded in 2017, Loft Orbital has flown over 25 missions and operates facilities in San Francisco, Colorado and Toulouse, France.
