Job Title: Senior Mechanical Design Engineer

Location: Sunnyvale, CA

Spectranetix, a small fast-growing company that develops and provides advanced electronic systems for the U.S. Department of Defense, is looking for a Senior Mechanical Design Engineer. We recently joined forces with Pacific Defense and our growth is accelerating!

Spectranetix designs and builds advanced, military standards-based, modular open systems architecture (MOSA) systems. These systems are used for multi-mission electronic warfare, tactical communications, signals intelligence, cyber-EW, high speed computing or simultaneous combinations of these capabilities.

Who are we looking for?

We are looking to hire a Senior Mechanical Design Engineer who wants to get involved in a fast-paced and dynamic company. As a Senior Mechanical Design Engineer at Spectranetix, you will be involved in mechanical design and packaging of high-speed circuit boards and systems that have tough requirements in thermal management including air and conduction cooling, EMI and RFI shielding, compact and rugged packaging constraints dealing with various MIL-STD environmental demands from ground based to airborne. These are complex mechanical modules with associated cable harnesses, related test fixtures, all with tight tolerances to support seamless system assembly, test, configuration, operation and servicing. You will work closely with a cross-domain team including RF and Digital engineers, systems engineers, test engineers, software engineers, manufacturing engineers to ensure a successful development.
