Thermal Engineer - Analysis & Test

Xona is the navigational intelligence company bringing real-time, centimeter-level certainty to any device, anywhere on Earth.

With Pulsar – the world’s most advanced PNT satellite infrastructure in Low Earth Orbit – Xona will offer a future-proof, backwards-compatible global positioning system optimized for absolute precision, superior power, and robust protection.

Role Overview

We are seeking a hands-on Thermal Engineer to support the thermal design and environmental verification of our spacecraft. This role combines thermal analysis with direct ownership of thermal test development and execution.

During the first year, the role is expected to be approximately 50% thermal analysis and 50% test work. Over time, it will shift toward increasing ownership of component-, subsystem-, and spacecraft-level thermal analysis.

You will own work from early thermal modeling and collaboration with mechanical designers through thermal-vacuum (TVAC), thermal-chamber, and targeted R&D test campaigns. You will work closely with mechanical, electrical, systems, integration, and test teams to turn hardware designs into credible thermal models, generate test evidence, correlate models to data, and drive design improvements.
