Description
Mechanical Engineer
We will consider junior or senior level engineer with experience in electronic enclosure , EMI / EMC skills and 3D skills
Job Responsibilities
Serve as mechanical design authority for electronic systems operating in secure, mission‑critical environments
Own mechanical architecture from requirements through production, including:
Enclosures, frames, and chassis
Shielding, gasketing, and EMI/EMC mitigation features
Thermal management (conduction, convection, forced‑air, passive solutions)
Structural integrity, vibration, and shock considerations
Translate electrical and system requirements into robust, producible mechanical designs.
Design mechanical solutions for sheet metal and CNC manufacturing processes which support TEMPEST or TEMPEST‑like mitigation strategies, including:
Shielded enclosures and covers
EMI gasketing, seams, bonding, and grounding paths
Cable ingress/egress control, connector placement, and isolation zones
Collaborate closely with Electrical Engineering to ensure enclosure and PCB/layout strategies are aligned for emissions control and signal integrity.
Support system‑level RED/BLACK separation concepts through mechanical partitioning and layout.
Create detailed 3D CAD models, assemblies, and production drawings using SolidWorks and ASYME 14.5 drawing standards.
Define tolerances using GD&T and tolerance stack-up analysis.
Perform Finite Element Analysis in SolidWorks.
Define finishes, materials, and fastener strategies suitable for secure and long‑lifecycle products.
Participate in prototype builds, fit checks, and bring‑up activities.
Support qualification, compliance, and environmental testing (EMI/EMC, thermal, vibration, shock as applicable).
Work closely with:
Electrical and PCB Design Engineers on component placement, stack‑ups, grounding, and shielding effectiveness
Manufacturing on DFM/DFA, tooling, and assembly processes
Supply chain on part selection, alternates, and obsolescence mitigation
Provide mechanical input during system design reviews, risk assessments, and design trades.
Interface with customers, program managers, and test labs when mechanical design decisions impact performance or compliance.
Support transition of designs into production, including documentation, assembly instructions, and test fixtures as needed.
Provide sustaining engineering support for field issues, updates, and product revisions.
Design with long‑term availability, serviceability, and configuration control in mind.
Qualifications
Bachelor’s degree in Mechanical Engineering or equivalent.
2+ years of professional mechanical engineering experience, including ownership of electronic enclosures or assemblies.
Strong hands‑on experience with:
Enclosure and chassis design for electronics
Thermal management of electronic systems
EMI‑aware mechanical design
Proven ability to work effectively in regulated, security‑sensitive engineering environments.
Experience supporting products from concept through production and sustainment.
Experience in the use of PLM software.
Experience with defense or aerospace product design and application of RTCA/DO-160G or related MIL standards.
Familiarity with EMI/EMC compliance testing and mitigation strategies from a mechanical perspective.
Experience with ruggedized designs subject to shock, vibration, and environmental extremes.
Prior experience serving as a technical lead or senior mechanical authority on multi‑disciplinary programs.
