Space Dynamics Laboratory Senior Mechanical Engineer in North Logan, Utah

Job ID: 6804B

Date Posted: April 21, 2026

At Space Dynamics Laboratory (SDL), you’ll lead the structural engineering of advanced electro-optical and infrared (IR) satellite payloads supporting critical national security and space missions. These are real flight systems—your work ensures hardware survives launch, operates in space, and delivers mission-critical performance.

We are seeking an experienced Mechanical Engineer to join our Civil & Commercial Space Division.  The selected candidate will own structural performance across the full lifecycle—from early design and finite element analysis (FEA) through environmental testing—working with a highly technical team developing spaceflight hardware and satellite systems.

The Civil & Commercial Space Division is at the forefront of scientific research and space exploration. We equip major Government and commercial missions with calibrated state-of-the-art sensors and satellites. We also provide world-class AI&T technologies and mission management. Our projects include challenges across planetary science, Earth observation, heliophysics, and astrophysics. Be part of a team that pushes the boundaries of what’s possible in space and contributes to monumental scientific discoveries.

What you’ll do

  • Lead structural design, analysis, and verification for satellite payloads, space instruments, and mechanical systems

  • Perform and guide finite element analysis (FEA) using tools such as NX Nastran, Femap, or similar

  • Analyze and validate performance under launch environments (random vibration, sine vibration, shock)

  • Evaluate thermal and cryogenic structural behavior, including thermal distortion and material properties

  • Conduct modal, dynamic, and nonlinear analysis of complex aerospace structures

  • Support environmental testing and structural verification (vibration testing, shock testing, etc.)

  • Serve as a technical authority in design reviews (PDR, CDR) and engineering decision-making

    Key areas of impact

  • Aerospace structures & satellite systems: Structural integrity of spaceflight hardware

  • Launch survivability: Random vibration, shock, and dynamic load analysis

  • Cryogenic engineering: Structural performance at low temperatures and thermal-structural coupling

  • Precision optical systems: Jitter analysis and micro-vibration control for high-stability payloads

  • Mechanical ground support equipment (MGSE): Structural design and certification

    What success looks like (first 6–12 months)

  • Lead FEA and structural analysis for an active satellite or space payload program

  • Deliver validated models correlated with test data

  • Contribute to major aerospace design reviews (PDR/CDR)

  • Improve modeling, simulation, or structural test processes

    What you bring (required)

  • Bachelor’s degree in mechanical engineering or aerospace engineering

  • 10+ years of experience in structural analysis, FEA, or mechanical engineering for aerospace, space, or high-performance systems

  • Strong experience with finite element analysis (FEA) tools (NX Nastran, Femap, ANSYS, or similar)

  • Experience with vibration analysis, modal analysis, and structural dynamics

  • Ability to lead complex engineering efforts from analysis through validation

  • Must be a U.S. citizen with the ability to obtain and maintain a U.S. Government security clearance

    Experience that will set you apart (preferred)

  • Experience with satellite systems, space payloads, or optical instruments

  • Background in cryogenic systems or thermal-structural analysis

  • Expertise in:

  • Fastened joint analysis

  • Jitter / vibro-acoustic analysis

  • Nonlinear FEA (contact, large deformation)

  • Adhesive bonding or fracture mechanics

  • Familiarity with NASA standards (NASA-STD-5001, GEVS, etc.)

  • Master’s degree or PhD in mechanical or aerospace engineering

  • Active security clearance

    Why this role stands out

  • Work on real satellite hardware and spaceflight systems

  • High ownership in a deeply technical engineering environment

  • Access to advanced test facilities (vibration, thermal vacuum, etc.)

  • Stable, long-term aerospace and defense programs

  • Located in Logan, Utah—close to mountains, skiing, and outdoor recreation

    *Salary Range

  • $116,000 - $205,000

  • Salary commensurate on education and relevant experience

    This range serves as a general guideline and may vary based on factors such as role, level, location, market conditions, and individual qualifications, including job-related skills, experience, and relevant education or training. The range displayed in the job advertisement reflects the minimum and maximum target salaries across all US locations.
