Job Summary
Aurex is seeking a Sr. Mechanical Systems Engineer / Technical Lead to design, develop, and deliver aerospace and defense hardware across multiple programs. This role combines hands-on mechanical design with technical leadership, supplier coordination, and responsibility for moving engineering work from customer requirements through fabrication, integration, and acceptance.
You will support work ranging from launch-vehicle and payload structures to complex fabricated assemblies and electronic equipment enclosures. You will develop and review CAD models and drawings, resolve manufacturing and interface issues, and work directly with customers and suppliers to establish achievable technical requirements.
The ideal candidate has taken hardware from concept through fabrication and test, understands how design decisions affect cost and schedule, and can lead technical execution while contributing directly to the engineering work.
Key Responsibilities
Mechanical Design & Development
- Develop mechanical concepts, CAD models, detailed drawings, and assembly documentation for aerospace and defense hardware.
- Translate customer requirements into designs with defined interfaces, materials, tolerances, and acceptance requirements.
- Evaluate designs for manufacturability, assembly, inspection, reliability, and cost.
- Work with structural analysts and other specialists to resolve design issues and incorporate analysis findings.
- Support equipment packaging and mechanical integration of electronic hardware.
Manufacturing & Supplier Coordination
- Assemble complete technical work packages for supplier quoting and fabrication.
- Review customer drawings and specifications to identify impractical tolerances, incomplete requirements, and manufacturing risks before work is committed.
- Work with customers and suppliers to resolve technical discrepancies and agree on achievable requirements.
- Support supplier selection, technical quote evaluations, fabrication reviews, and source inspection.
- Resolve manufacturing nonconformances and proposed substitutions through the appropriate engineering and quality processes.
Technical Leadership & Project Execution
- Serve as the technical lead for assigned hardware efforts, coordinating engineering tasks, interfaces, and deliverables.
- Develop and maintain engineering plans, estimates, schedules, and technical risk assessments.
- Coordinate with program management, Contracts, Quality, and suppliers to keep technical execution aligned with authorized scope.
- Identify changes affecting cost, schedule, or performance and communicate their impact before additional commitments are made.
- Support technical proposals, feasibility studies, and customer discussions across business units.
Integration, Testing & Documentation
- Support prototype assembly, hardware integration, troubleshooting, and verification testing.
- Develop and review test procedures and acceptance criteria with the responsible engineering and quality teams.
- Maintain configuration-controlled models, drawings, bills of material, and engineering change records.
- Prepare clear technical reports, review materials, and customer status updates.
- Capture design and manufacturing lessons for use on subsequent programs.
Basic Qualifications
- Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a closely related STEM discipline.
- 10+ years of professional experience in mechanical design, hardware development, or systems integration.
- Proficiency with SolidWorks or comparable 3D CAD software, including detailed drawings and assembly models.
- Experience applying geometric dimensioning and tolerancing and evaluating tolerance stack-ups.
- Practical knowledge of machining, welding, fabrication, materials, and assembly processes.
- Experience preparing engineering drawing packages and resolving technical questions with manufacturing suppliers.
- Experience supporting hardware through design reviews, fabrication, integration, and testing.
- Ability to lead technical discussions with customers, suppliers, and multidisciplinary engineering teams.
- Strong analytical, troubleshooting, documentation, and communication skills.
Preferred Qualifications
- Experience with launch vehicles, spacecraft hardware, payload adapters, propulsion hardware, or ground support equipment.
- Experience with large fabricated structures, precision machined components, and welded assemblies.
- Experience supporting structural analysis and translating analysis results into practical design changes.
- Familiarity with electronic packaging, PCB mechanical interfaces, connectors, cable routing, and enclosure design.
- Experience with Altium Designer or similar electronics design tools.
- Experience managing engineering projects, supplier schedules, technical risks, and customer deliverables.
- Experience developing technical proposals, statements of work, estimates, and development plans.
- Familiarity with aerospace quality systems, configuration management, and source-inspection activities.
