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
