Location: Onsite - Irvine CA

Industry: Aerospace & Defense

Citizenship Requirement: U.S. Citizen (No Dual Citizenship)

Role Overview

We are seeking two highly skilled Mechanical Engineers with experience in the Aerospace & Defense sector to support the development and integration of advanced thermal management subsystems used across military and commercial platforms globally. This role focuses on mechanical subsystem development from a packaging and integration perspective, including enclosure design and integration of electronic and fluid control components such as pumps, compressors, fans, and valves. The ideal candidate has hands-on experience developing aerospace-grade subsystems within defined volume and interface constraints, ensuring high reliability, environmental robustness, and compliance with industry standards.

These roles will support programs progressing from Preliminary Design Review (PDR) toward Critical Design Review (CDR) and will involve reuse and adaptation of existing product architectures.

Key Responsibilities

• Design and develop mechanical enclosures for aerospace electronic and control subsystems such as thermal management systems and related subsystems
• Package and integrate COTS and custom components into customer-defined volume constraints by integrating components including pumps, compressors, fans, valves, and control electronics
