Space Resources Multiphysics Simulation Engineer III – Molten Regolith Electrolysis Reactor

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our diverse team of problem solvers as we add new chapters to the history of spaceflight!

This position is part of the Space Systems Development (SSD) business unit. SSD develops next-generation concepts and systems to advance our future of living and working in space sustainably.

We believe that to preserve our planet, humanity must expand beyond our limits, venturing into space to explore and discover new energy and material resources.

In pursuit of this vision, we invite you to join our dynamic Space Resources Program. We’re dedicated to developing and demonstrating In-Situ Resource Utilization (ISRU) technologies for the Moon and beyond. If our mission resonates with you and you are eager to contribute, you could be the perfect addition to our inclusive, open-minded, and forward-thinking team.

In this role, you will work entirely onsite at our Los Angeles Facility with the Space Resources Program team. We’re seeking a dynamic engineer to join our Agile Hardware Development team. You will play a crucial role in all phases of our tech development and rapid product development cycle, from problem decomposition, design conceptualization, model development, and model validation/prototype demonstration.

The successful candidate will focus on answering design and subsystem operation questions using multi-physics simulations while engaging in an environment of high productivity and continuous improvement. This role requires exceptional knowledge of technology development for complex integrated systems, the ability to address and overcome roadblocks for the team and a willingness to engage in, learn from, and positively contribute to the success of a multidisciplinary, scrappy organization.

We work in fast-paced cycles of design, analysis, and integration to deliver a scalable solution. We’re looking for someone who is adaptable, willing to take action, eager to learn, and committed to safety and quality. Your creativity, innovative spirit, and ability to navigate changing requirements are crucial.
