Mechanical Engineer - Mission Modules

About Forterra

Forterra is a leading provider of autonomous systems for ground-based movement in the working world. Amongst some of the earliest innovators in the field of driverless technology, Forterra is focused on building systems that protect front-line soldiers and enable civilian workers in our industrial base. Forterra is the go-to provider of ground autonomy solutions for the U.S. Department of Defense, which harnesses the technology for asymmetric warfare in critical conditions.

About the role

Forterra is advancing the frontier of autonomous ground systems through a new generation of mission module capabilities—integrating payloads like Counter-UAS, fire-control, combat engineering, and advanced ISR onto rugged, vehicle-based platforms. We are looking for a skilled Mechanical Engineer to lead the design, analysis, and integration of mechanical systems that house, actuate, and protect these critical payloads.

This role will own the end-to-end mechanical design and integration of mission payloads into Forterra's autonomy platform. You will work closely with cross-functional teams—including electrical, autonomy, and systems engineering—as well as with government stakeholders and external subsystem partners to deliver robust, modular, and field-ready solutions.

What you'll do

• Design and package mechanical subsystems, including enclosures, mounts, thermal structures, and interfaces for ruggedized payload integration
• Create and manage detailed 3D CAD models, drawings, and assemblies using SolidWorks, Creo, or similar tools
• Perform structural, thermal, and vibration analysis (FEA / CFD) to ensure performance under operational and environmental loads
• Integrate mission-critical payloads—such as sensors, optics, and RF systems—into vehicle platforms with attention to mechanical, thermal, and access constraints
• Lead mechanical integration for subsystems involving hydraulic and pneumatic components
• Drive rapid prototyping and iterative development using additive manufacturing and hands-on assembly
• Ensure manufacturability, maintainability, and compliance with MIL-STD-810 and other relevant standards
• Collaborate cross-functionally and with external vendors to define and validate mechanical interfaces and system requirements
• Support field integration, testing, and troubleshooting across lab, range, and operational environments
• Participate in test campaigns, user feedback sessions, and system sustainment efforts
