Senior Mechanical Engineer, Hardware Test - X-BAT (R5271)

What you'll do:

Design and develop mechanical test fixtures, test stands, environmental test hardware, and integration tooling to support verification and validation activities.
Create detailed CAD models, engineering drawings, assembly instructions, and manufacturing documentation.
Support qualification, reliability, environmental, vibration, thermal, and endurance testing of X-BAT hardware.
Design systems that interface with aircraft structures, avionics, batteries, propulsion systems, payloads, and electromechanical assemblies.
Perform engineering analyses, including structural, thermal, and fatigue assessments, to ensure safe and reliable operation of test equipment.
Collaborate with cross-functional teams to define test requirements and develop effective test solutions.
Support root-cause investigations and failure analysis efforts by developing troubleshooting fixtures and diagnostic hardware.
Work with machine shops, vendors, and manufacturing partners to fabricate and assemble test equipment.
Assist with laboratory setup, equipment integration, and maintenance of test infrastructure.
Contribute to design reviews and advocate for design improvements that simplify testing and increase hardware reliability.
Support continuous improvement efforts focused on safety, test efficiency, repeatability, and scalability.

Required qualifications:

B.S. in Mechanical Engineering or related engineering discipline.
5+ years of experience designing mechanical systems, test equipment, aerospace hardware, or electromechanical systems.
Proficiency with CAD software such as NX, SolidWorks, CATIA, Creo, or similar.
Experience creating engineering drawings and releasing designs for fabrication and assembly.
Strong understanding of mechanical design fundamentals, materials, manufacturing processes, GD&T, and tolerance analysis.
Experience designing fixtures, tooling, test stands, or ground support equipment.
Hands-on experience building, integrating, and troubleshooting mechanical or electromechanical systems.
Strong analytical and problem-solving skills with the ability to work independently on moderately complex projects.
Ability to thrive in a fast-paced development environment with evolving priorities.

Preferred qualifications:

Experience supporting aerospace, defense, robotics, automotive, or autonomous systems programs.
Experience with finite element analysis (FEA) tools such as ANSYS, Abaqus, or Nastran.
Familiarity with environmental, vibration, thermal, and durability testing methods.
Experience working with instrumentation, sensors, data acquisition systems, and laboratory equipment.
Familiarity with aerospace qualification standards such as MIL-STD-810, DO-160, or equivalent.
Experience designing field-deployable or ruggedized test equipment.

Why this role matters:

The Hardware Test team plays a critical role in ensuring X-BAT hardware performs reliably in demanding operational environments. The test systems and infrastructure you develop will directly support the validation, qualification, and sustainment of mission-critical autonomous aircraft systems.
