Software Engineer at Epsilon3

Are you ready to help humanity reach the stars by building the software that powers modern space exploration? At Epsilon3, we are transforming how teams manage complex operations for spacecraft and advanced hardware. Founded in 2021 by veterans from SpaceX, Google, and NASA, we support over 100 missions and work with industry leaders like Blue Origin and Rocket Lab. With $15M in Series A funding from top-tier investors, we are looking for passionate engineers to join our mission-driven team.

We are seeking a Senior Software Engineer to join our team on a full-time basis. This role is remote and can be based anywhere in the United States. You will work with a modern stack including Node.js, React, Postgres, AWS, and Docker to solve high-stakes engineering challenges. Your core responsibilities will include:

• Designing, building, and releasing robust web-based operational dashboards and electronic procedure tools for space missions.
• Developing software that handles complex computations to support autonomous execution and critical decision-making.
• Deploying high-quality code daily to ensure rapid iteration and continuous improvement of our user experience.
