Mission Engineer II

As a key member of the Mission Engineering team, you will lead programs across commercial, defense, and space microreactor missions – both on Earth and in space. You will serve as a primary technical point of contact for customers and stakeholders, driving the development, deployment, and application of Antares systems to meet mission needs. You will operate at the intersection of engineering, product development, customer program execution, and mission integration, owning how the complete product is applied to real-world missions from concept through end of life.

You'll have strong engineering and physics fundamentals – particularly in thermodynamics, heat transfer, fluid mechanics, energy and power systems, and engineering economics – with demonstrated ability to reason from first principles, develop quantitative models, and maintain high technical rigor across disciplines. You will own product integration into operational end-user environments.
