We sit at the intersection of defense, robotics, and next-generation autonomy, powering the machines that are changing how militaries, first responders, and industries operate in the field. Our core purpose is simple: connect anyone and anything, at any time, in any place.

For over 25 years, our team has been at the forefront of mesh networking, partnering with leading defense programs, robotics manufacturers, and system integrators worldwide. The work here doesn't sit in a slide deck — it ends up in the field, in the hands of people for whom failure isn't an option.

About the Job

The MQE Product Engineer is the product quality specialist within the MQE team. Reporting to the MQE Manager, you will work alongside the Process Engineer and Test Engineer to support the Contract Manufacturing (CM) Manager in improving the manufacturing quality of our products.

While the Process Engineer improves how products are built and the Test Engineer maintains the test systems, the Product Engineer safeguards the product itself – its quality acceptance, defect disposition through the Material Review Board (MRB), production automation, cost of quality, and full traceability from incoming material to finished goods.

In close support of the CM Manager at our contract manufacturer in Batam, Indonesia, this role turns quality data into action: dispositioning non-conforming product, driving defect reduction with the Process and Test Engineers, and building the automation and tracking systems that make product quality visible and controllable.

What You'll Do
