What are the responsibilities and job description for the Mechanical Design Engineering III position at Mercury Systems?
Job Summary:
Mercury Systems is seeking the best and brightest talent to help us bring cutting edge technology to mission critical aerospace and defense applications. The Engineering team is seeking a Mechanical Engineer who can learn quickly and bring a fresh perspective to complex design challenges. In this role, you will have a hands-on opportunity to design, analyze, build, document, and test complex RF/Microwave assemblies and electronics subsystems. The ideal engineer will demonstrate strong cross-functional collaboration skills, while working effectively with program management, operations, supply chain, and quality teams to support the objectives of a high-impact defense program.
Job 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.
- Design of complex fixtures to support testing and advanced manufacturing techniques
- Review requirements and develop design verification and qualification test plans
- 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
- Assist with ongoing engineering development projects and product initiatives
- Support definition and implementation of 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.)
Required Qualifications:
- Bachelor's Degree in Mechanical Engineering or a related field
- Typically requires a minimum of 5 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
- Experience with hermetic sealing requirements, corrosion and finish control and process qualification analysis and reporting
- Ability to balance multiple and sometimes conflicting priorities
- 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 travel for product and development support across domestic Mercury sites and to external contract manufacturers and customers reviews up to 10%
- This position requires you to have or obtain a government security clearance in the future. Security clearances may only be granted to U.S. citizens.
Preferred 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
