Mechanical Engineer III
$93k - $134kW R Systems
Lead Mechanical Engineer Mission Out at sea, there’s no margin for failure. Naval systems must operate reliably in extreme conditions, constant vibration, high heat, saltwater corrosion, and continuous operational demand. The hardware that supports these missions must be engineered not just to function, but to endure. At WR, we design and deliver the mechanical and electrical systems that protect, support, and enable critical naval technologies. From concept through deployment, our work ensures that mission-critical equipment performs exactly as expected, when it matters most. The Opportunity We’re seeking a Mechanical Engineer III to take ownership of the design, development, and qualification of electromechanical systems supporting naval platforms. This role goes beyond design. You’ll help bring systems to life. From reviewing bill of materials and developing detailed technical data packages, your work ensures that what’s built can withstand the realities of the field. You’ll play a key role in translating engineering concepts into robust, manufacturable, and field-ready solutions. What You’ll Work On Design and develop electromechanical systems and mechanical components for naval applications Review and refine bill of materials (BOMs) to ensure accuracy, cost-efficiency, and manufacturability Create and maintain detailed technical data packages (TDPs) to support production and lifecycle management Develop 3D models and engineering drawings using Autodesk Inventor Support and contribute to environmental qualification testing (temperature, vibration, humidity, etc.) Collaborate with cross-functional teams to ensure seamless integration across mechanical, electrical, and system components Support prototype development, testing, and design iteration Ensure compliance with applicable military and industry standards What Makes This Role Different You’re not just designing parts, you’re ensuring systems survive real-world conditions at sea You’ll work across the full lifecycle: concept → design → analysis → testing → deployment Your designs will directly support mission readiness and operational reliability You’ll bridge the gap between engineering design and real-world performance Who This Role Is For This role is ideal for an engineer who: Thinks beyond CAD models and considers how things actually perform in the field Enjoys solving practical challenges like heat dissipation, durability, and manufacturability Takes pride in creating systems that are not only functional—but reliable under pressure Wants to lead design efforts and influence how systems are built and delivered Must-have Qualifications Bachelor of Science degree in Mechanical Engineering or related discipline. Six (6)+ years of full-time professional experience working as a Mechanical Engineer. Experience working with CAD software (AutoCAD and Autodesk Inventor preferred) with strong knowledge of 3D modeling, Bills of Materials (BOM), and manufacturing documentation. Ability to evaluate cost, manufacturability, and quality considerations in engineering designs. Preferred Qualifications Experience supporting DoD or Navy programs Familiarity with MIL-STD environmental requirements Experience with product lifecycle support from concept through production Prior experience leading or mentoring engineers Clearance Requirement Active DoD security clearance The selected candidate will be required to pass a pre-employment third-party background check which may include verification of any of the following: Employment history; Education and/or certifications; Criminal history; Driving Records; Other records or information related to the candidate’s suitability for the position.
