Senior Simulation Engineer

Northwood is on a mission to transform connectivity between Earth and space. Satellites are only as powerful as the ground systems that connect to them - without that critical infrastructure, they can’t be steered or send their data back to Earth. Northwood’s global ground network ensures that missions ranging from national security, to global connectivity, to disaster response can unlock their full potential and operate every day without fail. We take a vertically integrated approach to building an end-to-end ground system, delivering technology that is scalable and reliable for both government and commercial customers.

Backed by over $100M from investors like Andreessen Horowitz, Washington Harbour Partners, Alpine Space Ventures, Founders Fund, and others, Northwood has proven its ability to move fast – we’ve stood up a fully operational site in Australia in just 3 months, where similar efforts typically take years.

Northwood is rapidly scaling its global footprint, with 30+ sites planned across 2026 and 2027. We’re building and deploying infrastructure at a pace the industry hasn’t seen before. If you thrive on building quickly, solving hard problems, and seeing your work deployed globally on critical missions, we want you at Northwood.

Northwood is building a global network of next-generation ground stations, and we’re looking for a Senior Simulation Engineer to lead network architecting and modeling. You will own and develop analysis tools that enable insights into the network and planning of ground sites. You will answer questions such as “how many antennas should each site have to satisfy customer utilization?” And “where in the world should our next sites go?” You’ll partner closely with business development, sites rollout, RF, and software teams. This is a high leverage role that will guide the company's direction and our global network rollout. This position is based at our Los Angeles headquarters with possible travel to customer or ground station locations.
