Senior Mechanical Engineer

About the role

Mercury Systems is seeking a Mechanical Engineer to contribute to cutting-edge technology in mission-critical aerospace and defense applications. The role involves designing, analyzing, building, documenting, and testing complex RF/Microwave assemblies and electronics subsystems.

Responsibilities

• Design, analysis, and documentation of electromechanical hardware and/or systems for use in rugged military applications from proposal to production readiness gates
• Own mechanical architecture and detailed packaging design (enclosures, frames/stiffeners, retention/mounting, connector and RF launch features, sealing, EMI controls, thermal paths & interfaces)
• Flow system and customer requirements into mechanical requirements, margins, verification plans, and design trade documentation; lead peer and customer-facing design reviews and configuration-controlled documentation releases
• Support product verification testing including thermal, vibration, mechanical shock, humidity, and environmental stress screening
• Collaborate and effectively communicate with cross-functional product teams, including RF/Electrical Engineering, Test Engineering, Manufacturing, Quality Engineering, Supply chain management, and Procurement as part of your daily activities
• Aid in ongoing engineering development projects and product initiatives
• Assist with producibility improvements
• Hands-on prototype and qualification support (build support, failure analysis, corrective actions)
• Design/analyze hardware for mechanical shock, pyroshock, random vibration, acoustic environments and high g-loads; implement mitigations (load paths, stiffening, isolation, etc.)

Requirements

• Bachelor's Degree in Mechanical Engineering or a related field
• Typically requires a minimum of 4 years of experience in High Reliability, Aerospace, or Defense Electronics product with Hybrid RF microwave/microelectronics development and manufacturing
• Proficient with Solidworks 3D and AutoCAD 2D or equivalent software and drawing release and revision control discipline, GD&T, tolerance stack-up analysis competency
• Demonstrated PCB/PWB mechanical review influence (stack up/placement/mounting/outline) for operation and survivability in rugged military platform and munition applications
• Strong problem-solving skills within fast-paced environments, with a proven ability to collaborate and thrive in team-oriented settings
• Familiarity with material control processes and documentation such as routers, work instructions, etc. and tools related to those functions (Agile, Oracle, EPDM, etc.)
• Ability to balance multiple and sometimes conflicting priorities
• Experience with hermetic sealing requirements, corrosion and finish control and process qualification analysis and reporting

Qualifications

• Master's Degree in Mechanical Engineering or a related field
• Direct munitions/missile/expendables experience with emphasis on guided rockets, gun-launched munitions, seekers, exciters, and fuzing electronics
• Demonstrated experience designing and qualifying electronics packing for weapons systems using military environmental, safety, and EMI/E3 frameworks including MIL-STD-202/810/461/464/331/1250/1901/2105/2169, including translating requirements into mechanical margins, fixture design, instrumentation, and design updates from test results
• Familiarity with IPC assembly and acceptance standards including J-STD-001, IPC-A-610, IPC-6012, IPC-6018)
• Experience with transfer of design to production of new or existing designs
• Experience with Thermal Analysis (6SigmaET, Celsius EC Solver)
• Experience with Advanced Structural Analysis (Femap/NASTRAN)
• Experience with cable design and management
• Experience with machine shop tooling and practices (vertical mills, CNCs, etc.)
• Experience in failure analysis/Root-Cause Corrective Action (RCCA) investigations

Skills

• Strong problem-solving skills
• Effective communication and collaboration
• Proficiency in Solidworks 3D and AutoCAD 2D
• Experience with hermetic sealing and corrosion control
• Knowledge of IPC assembly and acceptance standards
• Experience with thermal and structural analysis
• Experience with cable design and machine shop practices
• Experience in failure analysis and RCA
