Employment Type: Full-Time | On-Site

EVONA is partnering with an innovative aerospace technology company developing cutting-edge communication systems for aircraft, satellites, and advanced defense applications.

We are seeking a Senior Mechanical Engineer to support the design, development, and qualification of advanced active phased array antenna systems (AESA) and ruggedized electronic hardware.

This is an exciting opportunity for an experienced mechanical engineer who enjoys hands-on engineering, complex technical challenges, and taking products from initial concept through manufacturing, testing, and qualification.

• Lead mechanical design activities from concept through production and qualification.

• Design ruggedized electronics packaging for aerospace and defense applications.

• Perform thermal, structural, shock, and vibration analysis using FEA tools.

• Develop mechanical solutions for airborne and terrestrial antenna systems.

• Support thermal management, EMI/EMC mitigation, and environmental qualification.

• Create detailed 3D CAD models, manufacturing drawings, and GD&T documentation.

• Collaborate closely with electrical, RF, manufacturing, and systems engineering teams.

• Apply design-for-manufacturing, assembly, testing, and reliability principles.

• Support environmental testing to DO-160G and MIL-STD-810 standards.

• Present technical designs to customers and engineering leadership.

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related discipline.

• 5+ years of mechanical design and analysis experience within aerospace, avionics, or ruggedized electronics.

• Strong experience designing electronics enclosures, assemblies, or aircraft structures.

• Proficiency with Solid Works or similar 3D CAD software.

• Experience with ANSYS or comparable FEA tools.

• Understanding of thermal management, vibration, stress, and structural analysis.

• Knowledge of CNC machining, GD&T, and precision manufacturing.

• Familiarity with EMI/EMC mitigation and electronics integration.

• Strong communication and cross-functional collaboration skills.

• Aerospace hardware development and environmental qualification.

• Active phased array antennas, avionics, or RF electronics packaging.

• Aircraft integration and mechanical interface design.

• DO-160G or MIL-STD-810 qualification.

• Previous technical leadership or project ownership.

• Opportunity to develop next-generation aerospace and defense technologies.

• Exposure to advanced antenna and communication systems.

• Collaborative, technically driven engineering environment.

• Comprehensive benefits and potential equity opportunities.
