Mechanical Engineer

Mechanical Engineer

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

Qualifications:

• 5+ years of experience in mechanical design and integration for autonomous systems, defense platforms, or robotics
• Deep proficiency in CAD modeling and mechanical drafting (Inventor, SolidWorks, Creo, or equivalent)
• Hands-on experience with structural, thermal, and shock/vibe simulation tools (e.g., ANSYS, COMSOL)
• Proven ability to design rugged systems meeting constraints for sealing, shock, vibration, and heat dissipation
• Knowledge of vehicle systems, especially hydraulic and pneumatic subsystem integration
• Strong capability in rapid prototyping and additive manufacturing workflows
• Familiarity with MIL-STD-810, MIL-STD-882, and other defense-relevant environmental and safety standards
• Experience with DFM/DFA principles and quick-turn prototype iteration
• U.S. persons and eligibility for a security clearance

Preferred Qualifications:

• Experience integrating defense-grade payloads or weapon systems
• Experience integrating sensors, optics, and other complex mechatronic systems into system-level architectures
• Background designing actuated or gimbaled electro-mechanical assemblies
• Knowledge of interface control documentation and system-level requirement flow down
• Field testing experience supporting live-fire, operational, or military exercises
• Familiarity with additive manufacturing tools and workflows. Strong cross-functional communication skills in high-stakes environments
