Job description

Assured Space Access Technologies, Inc. is a defense and engineering firm delivering phased array, radar, RF payload, and secure communications solutions to government and prime contractor customers. We are headquartered in Irvine, California. This role joins the Structures team, which designs the array support structure and enclosure for our mobile, ground-based phased array radar.

Team: Engineering, Ground-Based Radar (GBR), Mechanical Engineering

Location: Irvine, CA (on-site)

Employment Type: Full-Time, Exempt

Base Salary Range: $140,000 – $185,000

Clearance: This position requires the ability to obtain and maintain a U.S. Secret clearance, which requires U.S. citizenship. An active clearance is preferred.

Position Summary

As a Senior Mechanical Engineer on the Structures team, you will design and analyze the structure that carries the radar: the array support structure, the radar enclosure, and the way both mount to a mobile, trailer-based platform. Your structure must hold the array flat and aligned, survive transport and shock, withstand wind and weather in the field, and still be buildable by fabrication shops.

You will work with the Lead of Mechanical Engineering and with the array, cooling, beamformer, and systems teams on loads, interfaces, and deployment. This is a senior-level, hands-on seat for an engineer who can both design in SolidWorks and back the design with FEA and hand calculations, and who has taken structures from drawing to fabricated hardware.

Key Responsibilities

Structural Design

• Design the array support structure, radar enclosure, and mounting interfaces in SolidWorks, including weldments, machined parts, and sheet metal.
• Design the interface to the mobile/trailer platform, including deployment, leveling, stow, lifting, and tie-down provisions.
• Coordinate mechanical interfaces with the array, beamformer, cooling, and power teams, and keep interface definitions under control.

Structural Analysis

• Perform static, modal, random vibration, and shock analysis using FEA, supported by hand calculations.
• Analyze wind, environmental, and transportation loads, and define structural margins for operating and survival conditions.
• Evaluate deflection and alignment effects on the array, and work with systems engineers on structural impacts to radar performance.
• Correlate analysis with test data and update models and designs as needed.

Production, Test, and Field Support

• Release complete drawing packages and BOMs, and work with fabrication and machine shops on weld, machining, and finish requirements.
• Plan and support shock, vibration, and environmental testing of structural assemblies.
• Support integration, transport, and field deployment of the radar, and resolve structural issues found in build or test.

Required Qualifications

• Bachelor’s degree in Mechanical, Aerospace, Civil/Structural Engineering, or a related field.
• 8+ years of structural mechanical design and analysis experience on large electromechanical structures, enclosures, or vehicle- or trailer-mounted systems.
• Expert-level SolidWorks skills for structures, weldments, large assemblies, and production drawings.
• Hands-on FEA experience (Ansys, Nastran, or SolidWorks Simulation) for static, modal, vibration, and shock analysis.
• Experience analyzing wind, environmental, and transportation loads.
• Demonstrated experience taking structural designs into production, including weldments and machined parts, and working directly with fabrication shops.
• Working knowledge of GD&T per ASME Y14.5.
• Ability to obtain and maintain a U.S. Secret clearance, which requires U.S. citizenship.
• Ability to work on site in Irvine, CA.

Preferred Qualifications

• Structural design experience on phased array, radar, or antenna systems.
• Experience with military environmental and transportability requirements such as MIL-STD-810 and MIL-STD-209.
• Familiarity with structural welding standards such as AWS D1.1 and D1.2.
• Thermal or CFD exposure for enclosure and cooling interactions.
• Professional Engineer (PE) license.
• Active Secret or higher security clearance.

What we offer

• Medical, dental, and vision coverage; 401(k) with company matching; and paid time off.
• Professional development support, including training and certifications relevant to your field.
• Relocation assistance considered case by case.
• Hands-on ownership of real scope in a growing defense technology company.
