Lead Modeling & Simulation Systems Engineer

Umbra builds next-generation space systems that observe the Earth in unprecedented fidelity.

Our mission is to deliver global omniscience.

To stay ahead of climate change, geopolitical risk, and other major crises and issues, we need a global understanding of what is changing, where, and how fast. Umbra provides easy access to the highest quality commercial satellite data available, which is an indispensable tool for the growing number of organizations monitoring the Earth. We empower our customers to create the solutions that inform, inspire, and address our planet’s most pressing needs. We’re helping to create a brand new industry that has never meaningfully existed before.

We are seeking a Lead Modeling & Simulation Systems Engineer to drive Umbra Mission Solutions' efforts in analyzing complex systems through a unified toolkit. This technical leader will focus on integrating both new and existing tools across the company into a cohesive baseline for mission-level analysis, supporting Umbra’s diverse captures and programs. The ideal candidate will be an expert in multi-fidelity modeling and simulation, with a strong foundation in software development and a proven ability to collaborate effectively across technical teams. This role will involve close collaboration with spacecraft system and subsystem engineers, payload and RF engineers, and mission systems engineers to understand user requirements, integrate existing tools, develop new capabilities, and establish company-wide best practices for modeling and simulation.
