Git AI The Mechanical Engineer will lead the mechanical development of interceptor hardware from early architecture through prototype manufacturing and testing. Responsibilities include owning mechanical architecture, translating system requirements into designs, and providing technical direction.

Responsibilities

What You’ll Drive
Own the mechanical architecture and detailed design of interceptor hardware, including primary and secondary structures, motor mounts and interfaces, avionics packaging, internal mechanisms, enclosures, test fixtures, and ground-support equipment.
Translate incomplete system requirements, expected loads, environmental conditions, packaging constraints, and subsystem interfaces into practical mechanical designs and clear technical decisions.
Lead hardware through the full development cycle, including CAD, drawings, design reviews, supplier coordination, fabrication, inspection, assembly, integration, testing, failure investigation, and redesign.
Provide technical direction and design review to junior and mid-level engineers, improving design quality, manufacturability, documentation, and engineering judgment across the team.
Work directly with machinists, technicians, suppliers, and engineers to resolve difficult manufacturing, assembly, and integration issues without relying on organizational handoffs.
Plan and execute structural, environmental, propulsion-related, and vehicle-level tests, including test readiness, field operations, inspection, troubleshooting, repair, and rapid preparation for follow-on testing.
Lead failure investigations, identify root causes, and drive corrective actions through analysis, physical evidence, design changes, and validation testing.
Make and communicate clear tradeoffs among mass, strength, stiffness, reliability, manufacturability, cost, schedule, and test risk.
Establish lightweight technical standards and working methods that improve execution without slowing the pace of development.
Adapt quickly as program priorities, designs, schedules, suppliers, and test plans change in an early-stage startup environment.

Qualification

Strong mechanical design capabilityAbility to investigate failures

Required

Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related technical field.
At least five years of professional experience in rocketry, missiles, launch vehicles, propulsion, or a closely related aerospace field.
Demonstrated ownership of rocket or missile hardware from design through manufacturing, assembly, and test.
Strong mechanical design capability, including 3D CAD, production drawings, GD&T, tolerance analysis, material selection, fastening methods, and design for manufacturing and assembly.
Strong practical understanding of structural mechanics, load paths, vibration, shock, thermal effects, and the calculations required to support and review mechanical designs.
Experience leading complex hardware development or serving as a technical lead, including reviewing designs and guiding less-experienced engineers.
Experience working directly with machinists, technicians, fabrication suppliers, and test teams to solve real hardware problems.
Ability to investigate failures, make sound decisions with incomplete data, and rapidly convert findings into improved hardware.
Working knowledge of rocket or missile propulsion systems and the mechanical, thermal, and operational constraints they impose on the vehicle.
Ability to remain effective as priorities, requirements, and schedules change quickly.
Willingness and ability to spend approximately 50% of your time at remote test sites under demanding field conditions.
U.S. citizenship is required due to the nature of GITAI’s work with U.S. government customers and programs. This role may require eligibility to obtain and maintain a U.S. government security clearance.
