About The Position

Sedaro is hiring a Software Engineer to build powerful tools for modeling complex Aerospace simulations. You'll work across the full lifecycle—from the editor where engineers model systems and missions, to the workflow tools where they schedule simulation jobs, to the 3D playback and analytics dashboards where they explore and learn from the results. Team: Platform Services Location: 80% in-person in Arlington, VA or Boston, MA U.S. Citizen or permanent resident status required Who We Are Sedaro is a simulation platform company. Customers use our cloud platform to simulate satellite constellations and connected fleets, enabling the design and operation of systems at unprecedented scale. Enabling customers to playback and visualize multiple constellations, drill down into individual spacecraft sub-systems, and then compare thousands of variations of a simulation is a significant challenge, all built on Cesium, React, and TypeScript. We’re an early-stage company with serious traction, partnering with the Space Force and Shield AI to deliver next-gen systems, and we’re growing the team to match. Who You Are You want to build power tools for power users. You're drawn to interfaces where depth and efficiency matter more than onboarding simplicity. You're energized by novel problems where there isn't a ready-made answer. You'd rather ship and learn than polish in isolation. You're comfortable with scrappy prototypes and iterating in the open. You focus on impact. You care more about what your work enables than about how it was tracked.
