Defense Hardware: Mechanical Product Engineer (End-to-End)

Torrey Holistics; Sterling (VA); On-site; USD 85,000 - 125,000; Full time

Job summary

Torrey Holistics is seeking a mechanical design Engineer to own the end-to-end hardware development cycle—from concept through production readiness—for rugged defense and dual-use systems. You will design assemblies, enclosures, and interfaces, and work closely with machinists, suppliers, and program teams to hit cost, schedule, and reliability targets.

You have 3–5 years in mechanical design, strong SolidWorks skills, hands-on prototyping, and a passion for building robust hardware in a

Qualifications

• BS in Mechanical, Mechatronics, Aerospace, Manufacturing Engineering, or related field.
• 3–5 years in mechanical design, product development, prototyping, test, or multidisciplinary hardware development.
• Strong CAD fundamentals: modeling, assemblies, materials, tolerancing, fabrication methods, structural design, DFM.
• Advanced proficiency in SolidWorks (or equivalent) with production-quality drawings including GD&T and revision control.
• Hands-on proficiency with rapid prototyping, shop equipment, inspection tools, test equipment, and hardware bring-up.
• Working knowledge of electronics packaging, cable routing, thermal management, embedded systems integration, manufacturing, quality, test, and systems integration.

Responsibilities

• Architect and design: assemblies; ruggedized enclosures; brackets, mounts, panels, and structural components; mechanisms and interfaces; thermal solutions; fixtures/tooling; test equipment; production-ready components.
• Produce complete design packages: models, drawings, assemblies, BOMs, revision history, assembly instructions, and design rationale/trade studies.
• Prototype rapidly and iterate using shop tools, inspection equipment, and test instrumentation.
• Close the loop with manufacturing, quality, supply chain, and program teams to hit targets on manufacturability, assembly, inspection, cost, schedule, and reliability.
• Plan and run validation for fit/function, structural and durability performance, thermal response, manufacturability, assembly workflows, safety, and reliability.
• Analyze failures and test data; execute evidence-based design improvements.
• Collaborate directly with machinists, fabricators, vendors, and production to ensure design intent is realized.
• Mentor junior engineers; independently manage small projects from ambiguous requirements to delivered outcomes.
• Continuously improve engineering and manufacturing processes.
