Top Mechanical Design Engineer Jobs in Seattle, WA

Lead mechanical design of ground support equipment (GSE) for next-gen UAS: create CAD models and drawings, perform structural/thermal/fatigue analysis, oversee prototyping and testing, integrate with aircraft systems, support flight tests, and develop documentation for field sustainment.

Lead architecture, design, and development of precision wire harnesses and cable assemblies for autonomous UAVs. Own 3D CAD routing, analysis, prototypes, and testing. Perform electrical and environmental reliability analysis, integrate with avionics/systems/manufacturing, and mentor engineers to establish harness design best practices.

Design and develop structural and mechanism systems for autonomous UAV launch/recovery. Create CAD models, perform structural and kinematic calculations and preliminary FEA, prototype and test mechanisms, support pre-production and flight testing, collaborate with cross-functional teams, participate in design reviews, and improve design processes and configuration management.

Lead mechanical design of rugged, deployable Ground Support Equipment (GSE) for next-generation UAS. Create CAD models and drawings, perform structural/thermal/fatigue analyses, run trade studies, oversee prototyping and testing, develop technical documentation, collaborate with manufacturing/suppliers, and support flight test campaigns to meet military and aviation standards.

Lead end-to-end mechanical design and manufacturing for TCA rocket engine components. Drive DFM-focused design, tooling and fixture creation, implement advanced fabrication (additive, CNC, EDM, specialized joining), develop process parameters, and plan/execute hotfire test campaigns with analysis and rapid redesign for flight qualification.

Designs next-generation consumer hardware from early concepts through production. Partners with Industrial Design to develop mechanical architectures, prototypes, mechanisms, CAD models, materials, manufacturing approaches, and production-ready solutions. Applies DFM/DFA, GD&T, tolerance analysis, and mechanical engineering principles while collaborating with electrical engineering, manufacturing, suppliers, and prototype shops. The role emphasizes highly cosmetic products, ergonomics, form, aesthetics, functional integration, and rapid design iteration.

Design and develop mechanisms for satellite production, owning projects from concept to completion, while partnering with flight design and managing multiple tasks in a fast-paced environment.

Lead mechanical system and structural hardware design from concept to production. Create 3D models, drawings, BOMs, and manufacturing documentation. Perform analyses, tolerance studies, and support prototyping, testing, and production transition while mentoring junior engineers and ensuring compliance with aerospace standards.

Collaborate on mechanical designs for data center systems, validating performance, overseeing construction, and ensuring designs meet quality benchmarks.

Lead mechanical engineering evaluations for data center opportunities, assessing HVAC, cooling, chiller, CRAH/CRAC, liquid cooling, and critical equipment systems. Conduct facility due diligence, validate capacity and design assumptions, evaluate vendors and deployment risks, and provide feasibility and Go/No-Go recommendations. Support mechanical design strategies, equipment selection, commissioning, and construction readiness while partnering with engineering teams, consultants, and vendors to establish scalable standards for hyperscale and AI infrastructure.

The role involves designing electromechanical solutions for telecom systems, focusing on mechanical designs, thermal management, and product development. Responsibilities include overseeing prototype builds, collaborating with teams, and applying best practices in engineering.
