How to Apply for Software Engineer, Mission Systems

at Planet

🏢 About Planet

Planet is a unique Earth-imaging company that operates the largest constellation of satellites, providing daily global imagery to monitor environmental changes, agriculture, and urban development. Working here means contributing to a mission-driven team that uses cutting-edge technology to empower stewardship of our planet.

About This Role

As a Software Engineer on the Mission Systems team, you'll design and maintain the automation and services that keep Planet's satellite constellation running smoothly. This includes building HTTP APIs, evaluating new software, and collaborating with cross-functional teams to ensure mission success—directly impacting how we monitor Earth from space.

💡 A Day in the Life

Your day might start with a stand-up meeting with the Mission Systems team to discuss ongoing API improvements or operational issues. You'll then dive into coding—perhaps implementing a new endpoint for satellite tasking or debugging a CI pipeline failure. Later, you might collaborate with Satellite Operations to refine automation scripts or review a colleague's pull request, all while keeping an eye on system reliability metrics.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Design an HTTP API for a satellite command scheduling system—discuss endpoints, error handling, and scalability.
2 How would you implement automated testing for a satellite telemetry processing pipeline?
3 Walk through a CI/CD pipeline you've built: tools, stages, and how you ensure reliability.
4 Describe a time you debugged a complex issue in a production system—what was your approach?
5 How would you prioritize features when balancing satellite operations needs with product requirements?

⚠️ Common Mistakes to Avoid

  • Don't submit a generic cover letter—specifically address Planet's mission and this role's focus on satellite operations.
  • Avoid overemphasizing front-end or mobile development skills; this role is backend/infrastructure-focused.
  • Don't ignore the cross-functional aspect: failing to mention teamwork or collaboration can hurt your application.
