How to Apply for Software Engineer, Mission Systems

at Planet

🏢 About Planet

Planet operates the largest constellation of imaging satellites in history, providing daily Earth imagery to commercial, environmental, and humanitarian sectors. As both a space and data company, Planet offers a unique blend of hardware, software, and mission-critical operations. Working here means contributing to a mission that changes how people see and steward the planet.

About This Role

As a Software Engineer on the Mission Systems team, you'll build and maintain Mission Control, the web-based application that spacecraft operators use to monitor and control Planet's satellite fleet. Your work directly enables the health and operations of the largest satellite constellation ever flown, making every line of code impactful for real-time space operations.

💡 A Day in the Life

You might start by reviewing telemetry data from overnight passes, then join a standup with operators to prioritize features. The rest of the day could involve coding a new alerting dashboard, debugging a data pipeline issue, and collaborating with a spacecraft engineer on a user interface improvement.

🎯 Who Planet Is Looking For

  • Strong experience with web frontend frameworks (e.g., React, Angular) and backend services (e.g., Python, Go) for building real-time monitoring tools.
  • Familiarity with satellite operations, spacecraft telemetry, or mission control systems—or a strong desire to learn space domain concepts.
  • Ability to design and implement reliable, fault-tolerant systems that handle high-frequency data streams from thousands of satellites.
  • Comfortable working in a fast-paced, cross-functional team with engineers, operators, and data scientists to iterate on mission-critical features.

📝 Tips for Applying to Planet

1

Tailor your resume to highlight experience with real-time data visualization, telemetry processing, or similar mission-critical systems.

2

In your cover letter, explicitly connect your software engineering skills to the impact on satellite operations—show you understand the domain.

3

Mention any open-source contributions or side projects related to space, satellites, or distributed systems.

4

Research Planet's satellite technology (e.g., Doves, SuperDoves) and reference how your work could improve constellation management.

5

Emphasize experience with remote collaboration and asynchronous communication, as the team is global and remote-first.

✉️ What to Emphasize in Your Cover Letter

['Your passion for space technology and how your software skills can directly improve satellite fleet operations.', 'Specific examples of building user-facing tools for monitoring or controlling complex systems (e.g., IoT, robotics, or aerospace).', "Understanding of Planet's mission to make Earth imagery accessible and how Mission Control enables that.", 'Ability to work in a fast-paced, iterative environment with a focus on reliability and user experience.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Read about Planet's satellite constellation (Dove, SuperDove, SkySat) and how Mission Control fits into the operations workflow.
  • → Understand the concept of 'mission systems' in aerospace: command & control, telemetry, and anomaly response.
  • → Review Planet's engineering blog or talks to learn about their tech stack and cultural values.
  • → Check recent news about Planet's launches, product updates, or partnerships to show current awareness.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Design a real-time telemetry dashboard that displays satellite health data from thousands of spacecraft.
2 How would you handle data consistency and fault tolerance when processing high-velocity telemetry streams?
3 Explain your experience with web technologies (React, WebSockets, etc.) for building interactive monitoring interfaces.
4 Describe a time you had to debug a complex system under time pressure—how did you prioritize?
5 What interests you about working at Planet specifically, and how do you see software engineering contributing to space operations?

⚠️ Common Mistakes to Avoid

  • Don't submit a generic application—failing to mention space or satellite operations signals lack of interest.
  • Avoid exaggerating experience with real-time systems if you don't have it; instead, show eagerness to learn the domain.
  • Don't ignore the remote-first culture: emphasize your self-motivation and communication skills for distributed teams.
