Prepares milestone gate reviews, coordinates integration and test activities, manages risks and opportunities, presents technical information, and mentors other systems engineers. The role requires on-site work and an active Top Secret/SCI clearance with polygraph eligibility.

Thermal Engineering Intern supporting thermal design and analysis of spacecraft, aerospace hardware, cryogenic systems, and related equipment. Responsibilities include heat-transfer calculations, thermal modeling, load and environment development, environmental testing, technical documentation, engineering reports, and cross-functional IPT collaboration. The intern will apply academic knowledge to solve thermal problems, communicate technical findings, and support program cost, schedule, and technical requirements in an on-site environment.

Supports systems engineering throughout the space mission lifecycle, including requirements development, allocation, traceability, verification, validation, interfaces, technical documentation, MBSE modeling, integration and testing, and major design reviews. Collaborates with technical teams and subject matter experts to convert product requirements into integrated system solutions. The role is on-site five days per week and requires an active Top Secret/SCI clearance with potential polygraph eligibility.

Designs, simulates, tests, and documents RF passive and active circuits for phased-array antennas, receivers, transmitters, oscillators, and RF subsystems from VHF through 20 GHz. Uses MATLAB and RF simulation tools, performs laboratory measurements, designs PCBs and chip-and-wire components, troubleshoots hardware, and guides junior engineers and technicians. Collaborates with cross-functional teams and customers while supporting producibility, testing, presentations, and technical project execution.

Supports systems engineering across the full space mission lifecycle, including requirements development, allocation, traceability, verification, validation, interface management, MBSE modeling, integration and test planning, and technical documentation. Coordinates with subject matter experts, prepares materials for major design reviews, supports SEMP execution, and presents technical information to stakeholders. The role is on-site five days per week and may involve work in laboratories, production areas, cleanrooms, and other facilities.

Thermal Engineering Intern supporting thermal design and analysis of spacecraft, aerospace hardware, cryogenic systems, and related equipment. Responsibilities include heat transfer and thermal modeling, developing thermal loads and environments, supporting environmental testing, reviewing engineering documentation, preparing reports and procedures, and collaborating in integrated engineering teams. The role is on-site five days per week and may involve work in laboratories, production areas, cleanrooms, and other facilities.

Develops and qualifies materials and manufacturing processes for aerospace and defense hardware. Responsibilities include material selection, process planning, drawing reviews, laboratory testing, data analysis, failure investigations, root cause and corrective action, supplier requirement flow-down, and cross-functional support for design and production. The role works across offices, laboratories, production floors, and cleanrooms, requiring aerospace materials experience and a DoW Interim Secret clearance.

Structural Engineering Intern supporting analysis of spacecraft, satellites, tactical hardware, and related systems. Responsibilities include stress analysis using closed-form and finite element methods, structural dynamics, loads analysis, engineering reporting, test requirement development, and structural and vibration testing. The role is fully on-site and requires collaboration across engineering teams.

Embedded Software Engineering Intern supporting aerospace, avionics, tactical, and space-based systems. Responsibilities include developing and modifying embedded software, performing requirements analysis, architecture, design, coding, testing, integration, documentation, and collaborating with engineering teams. The role is part of a structured internship program and requires on-site work five days per week.
