Spacecraft Thermal Engineer; Mid-Career

Spacecraft Thermal Engineer (Mid-Career) - Millennium Space Systems

Millennium Space Systems

Job Description

Millennium Space Systems, a part of Boeing Defense, Space and Security (BDS), is a fast, agile small satellite company focused on national security space. Our missions have direct impact to global security, like missile warning and Earth observation.

Our team is curious, bold and innovative. We take risks, innovate and explore new techniques and technologies. We influence change because we challenge the status quo. And when we watch our satellites launch, we know each one of us made it happen.

Job Summary

As a Mission Operations Engineer, you will be the lead technical authority for Millennium’s on-orbit spacecraft. Your work will encompass the entire spacecraft mission life cycle, from the proposal phase to spacecraft and mission design, through space vehicle integration and test, and culminating with launch and on-orbit operations. You will be responsible for all facets of the mission design, including definition of operational concepts, development of on-orbit procedures, and innovation of advanced methods of spacecraft operation unique to each space mission.

Mission Operations requires composure in high-pressure situations, in-depth knowledge of both the space vehicles and ground segment, and an ability to respond to anomalous scenarios in real-time. You will be directly responsible for Millennium’s critical on-orbit assets.

This position’s internal job code is Systems Engineer. Our team is currently hiring for levels 3-4.

Job Summary

Thermal Engineers support the Spacecraft Development Program Managers and Chief Systems Engineer through the development of all spacecraft thermal system configurations, designs, analyses, testing, and flight operations. Spacecraft thermal subsystem elements includes all passive and active means of controlling the satellite’s system, subsystem, and component environments within both operating and survival limits during all pertinent system lifetime activities. Thermal engineers also have the opportunity to support MLI blanket design, fabrication, and installation.

This position’s internal job code is Mechanical System Design & Analysis Engineer. Our team is currently hiring for a level 3-4.

Responsibilities

• Perform spacecraft thermal design and analyses at the board, component, subsystem, and system level
• Develop systems and spacecraft element thermal models to predict thermal loads, impacts, and temperature margins to support system design
• Brief design and analysis materials to program managers, customers, and/or sponsors
• Identify all materials, processes, and facilities to achieve a qualified spacecraft thermal design and operation
• Assists in proposal and new business development efforts
• Support thermal verification testing on spacecraft systems and components including test design, test conduct, data reduction, analysis, and reporting
• Support the development of tools to aide in conceptual designs and post-processing analysis
• Potential to cross-train with MLI team for hands‑on support

This position is expected to be 100% onsite. The selected candidate will be required to work onsite at one of the listed location options.

Security Clearance and Export Control Requirements

This position must meet Export Control compliance requirements, therefore a “US Person” as defined by 22 C.F.R. § 120.15 is required. “US Person” includes US Citizen, lawful permanent resident, refugee, or asylee.
