The Opportunity:

Grow your software engineering career with meaningful impact as a Software Engineer working in the space domain!

We're looking for capable, motivated developers with 3+ years of experience who are ready to take on more independence and grow their technical skills. As a Software Engineer, you'll work on mission-critical space system software, delivering features with increasing autonomy while continuing to develop your expertise alongside senior engineers.

You'll implement well-architected solutions, collaborate across teams to deliver features, and contribute to our engineering culture. You're past the "learning the basics" stage—now it's about deepening your skills, handling more complex problems, and starting to help others grow.

You will be responsible for implementing features end-to-end, writing robust tests, participating in code reviews, and troubleshooting system issues. Solid experience with modern development practices, APIs, and cloud platforms is important.

If you're passionate about technology, ready to grow beyond junior-level work, and excited to make an impact on space mission systems, we would love to hear from you!

What makes this role exciting:

• Deliver features independently - take ownership of well-scoped features from implementation through deployment
• Expand your expertise - work with modern technologies (Python, React, AWS/Azure, Kubernetes) with increasing complexity
• Collaborate and learn - work alongside senior and staff engineers who will help you level up your skills
• Space domain impact - build software that directly supports critical space missions
