Anduril Industries is a defense technology company with a mission to transform U.S. and allied military capabilities with advanced technology. By bringing the expertise, technology, and business model of the 21st century’s most innovative companies to the defense industry, Anduril is changing how military systems are designed, built and sold. Anduril’s family of systems is powered by Lattice OS, an AI-powered operating system that turns thousands of data streams into a realtime, 3D command and control center. As the world enters an era of strategic competition, Anduril is committed to bringing cutting-edge autonomy, AI, computer vision, sensor fusion, and networking technology to the military in months, not years. The Test and Analysis team is responsible for ensuring that emerging products are ready for the harsh conditions of air, land, sea, and space environments. Our team supports multi-disciplinary product teams across the full life cycle to design, develop, and validate new and existing products. This includes requirements analysis, environmental and electromagnetic interference testing, reliability testing, and manufacturing sustainment efforts. The Test and Analysis team achieves these objectives through consistently striving to understand primary design drivers through analytical modeling, including specialized structural-thermal-optical performance (STOP) analysis, along with strategic engineering validation and qualification test campaigns. This fused approach ultimately enables us to identify opportunities for product robustness and quickly implement solutions to ensure critical capabilities efficiently make it into the hands of our military and its allies. We are looking for a Senior Thermal Engineer to join our rapidly growing analysis team in Lexington, MA. In this role, you will be responsible for performing thermal analysis and taking ownership of thermal design aspects across hardware development programs. You will execute first order assessment of designs to guide preliminary design architecture, develop detailed analytical models to mature prototype designs and develop predictions to support hardware testing.  If you are someone who is excited to work on new projects from conceptualization through production and are passionate about developing validated and correlated models to support the rapid prototyping of cutting edge systems.
