Mechanical Engineer - Advanced Mechanical SystemsDesign Complex Systems. Solve Technical Challenges. Support Next-Generation Testing.
Are you a Mechanical Engineer who enjoys working on highly custom equipment, complex mechanical systems, and challenging engineering problems that do not come with a one-size-fits-all solution?
We are seeking a skilled Mechanical Engineer to support the design, analysis, and validation of custom mechanical and structural systems used in advanced wind tunnel and ground test environments. This role is ideal for someone who enjoys taking concepts from early design through analysis, documentation, fabrication support, installation, and commissioning.
If you have experience with mechanical design, FEA, welded steel structures, pressure vessels, piping systems, process equipment, and large industrial systems, this is a great opportunity to work on technically challenging projects in a collaborative engineering environment.
What You'll Be Doing
As a Mechanical Engineer, you will help design and validate custom mechanical systems and equipment for new facilities, major upgrades, and complex test environments.
Key Responsibilities
Design and develop mechanical subsystems for custom engineered equipment and facility upgrades.
Work on systems that may include:
Welded steel structures
Pressure vessels
Piping systems
Mechanical mechanisms
Rotating equipment
Pneumatic systems
Hydraulic systems
Fuel systems
Cooling water systems
Process equipment
Perform FEA and supporting calculations to validate mechanical and structural designs.
Develop design criteria, calculation packages, procurement specifications, technical reports, and verification plans.
Collaborate with designers to create accurate drawings, bills of material, and manufacturing documentation.
Review designs for manufacturability, performance, safety, and customer requirements.
Support procurement and subcontractor coordination when components or systems are outsourced.
Participate in internal and customer design reviews.
Provide technical support to fabrication, procurement, assembly, installation, and commissioning teams.
Assist with vendor selection, quality review, site surveys, and equipment installation.
Coordinate with project managers, chief engineers, and cross-functional engineering teams.
Support future project proposals through technical concepts, cost estimates, and written proposal content.
What We're Looking ForRequired Experience
Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or equivalent education and experience.
5+ years of experience in mechanical design, systems engineering, or design engineering.
Experience with large industrial equipment, complex mechanical systems, or facility-based engineering projects.
Proficiency with 3D CAD tools for mechanical design.
SolidWorks experience preferred, but other 3D CAD platforms will be considered.
Strong FEA experience for mechanical and structural analysis.
ANSYS experience preferred, or similar FEA software.
Experience designing and analyzing welded steel structures.
Experience with fluid/process systems including valves, filters, pumps, instrumentation, and piping.
Knowledge of fabrication methods such as forming, welding, machining, and additive manufacturing.
Experience with pressure vessels and piping systems using applicable codes such as B31.3, PED, or similar standards.
Familiarity with GD&T and engineering documentation standards.
Ability to work in a multidisciplinary engineering environment.
Strong communication, organization, and problem-solving skills.
Ability to manage multiple projects and priorities independently.
Ability to travel domestically and internationally as needed, typically less than 10%.
Must meet US Person requirements based on applicable security requirements.
Preferred Background
Candidates with experience in any of the following areas are highly encouraged to apply:
Aerospace engineering environments
Wind tunnel or ground test facilities
Large industrial equipment
Custom mechanical equipment
High-temperature systems
Mechanical test systems
Pressure vessels and process piping
Structural analysis and mechanical substantiation
Advanced manufacturing environments
New facility development or major facility upgrades
Additional strengths include:
Experience with high-temperature environments above approximately 2000°F
Transient heat transfer analysis
Cooling method design
High-temperature materials such as superalloys, ceramics, or thermal barrier coatings
Understanding of subsonic, supersonic, or hypersonic aerodynamics
Experience with FMEA, HAZOP, safety risk assessments, or similar risk analysis methods
Ability to lead or contribute to customer-facing design reviews
Experience supporting technical proposal development
What Makes You Successful
You are a hands-on engineer who enjoys solving problems that require both technical depth and practical judgment.
You understand how to move a design from concept to analysis, documentation, fabrication, and installation. You are comfortable working with designers, project managers, vendors, and technical teams to keep projects moving while maintaining quality and accuracy.
You take ownership of your work, communicate clearly, and enjoy being part of a team that is building complex systems where details matter.
Why This Opportunity?
Work on highly custom mechanical systems and one-of-a-kind equipment
Support advanced wind tunnel, aerospace, and complex test facility projects
Collaborate with multidisciplinary engineering teams
Use modern design and analysis tools including 3D CAD and FEA
Gain exposure to design, fabrication, installation, and commissioning
Contribute to a growing organization with technically challenging project work
Play a meaningful role in new facility development and major system upgrades
