Looking for an opportunity to make an impact?

At Leidos, we deliver innovative solutions through the efforts of our diverse and talented people who are dedicated to our customers’ success. We empower our teams, contribute to our communities, and operate sustainably. Everything we do is built on a commitment to do the right thing for our customers, our people, and our community. Our Mission, Vision, and Values guide the way we do business.

Your greatest work is ahead!

Leidos Defense is seeking a Lead Thermal/Stress Analyst to join our team in Huntsville Alabama designing and analyzing the next generation of defense systems to protect America and its allies. You will perform stress and thermal analysis to support the design of cutting edge aerospace and defense programs. You will collaborate with designers and use Star CCM+ and FEMAP daily to ensure your team’s design meets requirements. You might work alongside the production team to install hardware or verify requirements. Then you’ll work with the testing team to put your hardware into action. This is not your average engineering position. You are applying to be part of a team of the most talented engineers in the region who push you to be better every day. This is a fast-paced program with unique technical challenges that will be a rewarding milestone in any engineering career.

If you are up for the challenge of joining this team, then apply now to be considered!

Leidos Defense provides a diverse portfolio of systems, solutions, and services covering land, sea, air, space, and cyberspace for customers worldwide. Solutions for Defense include enterprise and mission IT, large-scale intelligence systems, command and control, geospatial and data analytics, cybersecurity, logistics, training, and intelligence analysis and operations support. Our team is solving the world’s toughest security challenges for customers with “can’t fail” missions. To explore and learn more, click here!

THE CHALLENGE (primary responsibilities)

• Are you ready to tackle complex engineering challenges? In this role, you will perform stress and thermal analysis on structural, electronic, and mechanical systems while supporting critical test activities. Assignments may require expertise in stress analysis, thermal analysis, or both.
• Stress analysis will involve analytical methods, finite element models/simulations, and advanced analysis tools. You will produce models, perform calculations, reduce data, and correlate test results to ensure accuracy and reliability.
• Thermal analysis will include hand analysis methods, finite volume models/simulations, finite element models/simulations, finite difference models/simulations, and other tools. You will conduct detailed steady-state and/or transient thermal analyses using industry-standard programs, producing models, performing calculations, reducing data, and correlating test results to thermal and flow models.
• You will collaborate closely with design and manufacturing teams to create designs that meet stringent performance, manufacturability, and schedule requirements.
• This is an in-office position with flexibility in schedule and work location. Remote work is the exception in your week, not the norm.

WHAT SETS YOU APART (basic qualifications)

• Bachelor's degree in Mechanical or Aerospace Engineering from an ABET-accredited university.
• Minimum of 4 years of experience with a BS degree or 2 years with an MS degree.
• Direct experience performing stress and thermal analysis in the aerospace or defense industry.
• Demonstrated experience with commercial finite element analysis tools such as FEMAP/NX NASTRAN, PATRAN/MSC NASTRAN, ANSYS, Abaqus, or similar software is essential.
• Proven working knowledge of commercial thermal analysis and CFD tools like STAR-CCM+, Thermal Desktop/SindaFluint, ANSYS, or SolidWorks FlowSimulation.
• You must be able to write clear, concise technical reports and present data effectively to multi-disciplinary teams.
• You must be capable of contributing as part of a larger analysis team or independently as the sole analyst on a project. Experience mentoring and leading younger analysts is highly valued.
• You must be a U.S. Citizen and be eligible to obtain and maintain a Final Secret Clearance.
• Residency in the Huntsville, AL area or willingness to relocate to Huntsville, AL is required.

Preferred Qualifications

• Fluid lumped capacitance modeling
• Electronics cooling analysis
• Thermal analysis of orthotropic materials
• FEMAP/Nastran
• Coupled thermal-structural analysis
• Bolted joint and weld analysis
• Dynamics analysis (modal, response spectrum, shock, vibration)
• Fatigue analysis
• Composite materials
