Date Posted:

March 19, 2026 Space Dynamics Laboratory (SDL) is seeking a Senior Mechanical Engineer to lead structural engineering of world-class electro-optical and infrared (IR) satellite instruments. You will serve as a primary technical authority ensuring that high-precision payloads and complex Mechanical Ground Support Equipment (MGSE) withstand the dual challenges of violent launch dynamics and the extreme thermal gradients of cryogenic operations. You will be responsible for the full lifecycle of structural verification, from initial concept modeling to final environmental testing in SDL's state-of-the-art facilities.

Essential Functions and Responsibilities:

Analysis Mastery:

Directs high-fidelity Finite Element Analysis (FEA) activities, specifically utilizing Femap with NX Nastran for linear/nonlinear statics, normal modes, buckling, random vibration, and stability assessments

Dynamics & Environmental Verification:

Defines and validates hardware responses to launch environments through Random Vibration, sine-sweep, and mechanical shock analysis, ensuring compliance with NASA-STD-5001 and

GSFC-STD-7000

(GEVS); writes and executes structural verification tests

GSE Stewardship:

Oversees the structural certification of specialized MGSE, including high-vacuum compatible lifting fixtures and transport containers for sensitive flight optics

Technical Governance:

Serves as the Lead Structural Reviewer for Program Life Cycle Reviews (PDR, CDR, SIR) and provide expert leadership for Material Review Boards (MRB)

Cryogenic Structural Integrity:

Leads the structural design and analysis of opto-mechanical sensor assemblies operating at deep cryogenic temperatures (
