How to apply for RF Engineer - Part Time

About Planet

Planet uniquely combines space technology with data analytics, operating the world's largest constellation of Earth-imaging satellites. They control the entire pipeline from satellite design to data delivery, offering engineers the rare opportunity to work on complete space systems. Their mission-driven focus on environmental stewardship and global impact makes them appealing to those wanting to apply RF engineering to solve real-world problems.

About the role

This part-time RF Engineer role involves designing and optimizing communication systems for Planet's next-generation small satellite buses, specifically for the Pelican optical imaging and Carbon Mapper hyperspectral payloads. You'll contribute to complex RF systems including transceivers, PLL synthesizers, and other components for both space and ground station applications, directly supporting the collection of critical Earth observation data.

A typical day

A typical day might involve simulating RF circuit performance for satellite communication systems, collaborating remotely with hardware teams on component selection, and analyzing test data from prototype designs. You'll balance academic commitments with contributing to real satellite projects, potentially participating in virtual design reviews and troubleshooting RF issues affecting data downlink from Planet's constellation.

Who Planet is looking for

• Currently in senior year of Electrical Engineering, Physics, or Computer Science with strong academic performance in RF/MW and electromagnetics courses
• Has hands-on experience or coursework projects involving RF building blocks like mixers, switches, amplifiers, oscillators, filters, or PLL synthesizers
• Demonstrates ability to quickly learn and apply knowledge across multiple domains, from modem PHY layer to active RF circuits
• Shows genuine interest in space technology applications and can articulate how RF engineering contributes to Earth observation missions

Tips for this application

• Highlight any academic projects or research involving RF circuit design, signal processing, or electromagnetics - be specific about your contributions
• Mention any experience with space-related projects, ham radio, or satellite communications even if informal
• Demonstrate knowledge of Planet's specific satellite constellations (like Pelican and Carbon Mapper mentioned in the description)
• Emphasize your ability to work independently in a remote setting, crucial for this part-time remote position
• Connect your skills to both space systems AND ground station components, showing understanding of the complete communication chain

What to cover in your cover letter

["Explain why Planet's mission of Earth observation through satellite technology specifically appeals to you", 'Detail your most relevant coursework or projects in RF/MW, electromagnetics, or signal processing', "Describe how you've successfully learned and applied new technical skills quickly in past experiences", 'Express your understanding of the unique challenges of RF design for space applications versus terrestrial systems']

Research before applying

• Study Planet's existing satellite constellations and their technical specifications
• Understand the differences between optical imaging (Pelican) and hyperspectral payloads (Carbon Mapper)
• Research the challenges specific to RF design for small satellites versus traditional large satellites
• Learn about Planet's data applications in environmental monitoring, agriculture, or disaster response

Likely interview topics

Based on the job description, expect questions about:

• Technical questions about specific RF components mentioned: PLL synthesizers, mixers, RF amplifiers, or filters
• Discussion of trade-offs in RF system design for small satellite constraints (size, weight, power)
• How you would approach learning new domains like modem PHY layer or space-qualified components
• Your understanding of the complete satellite-to-ground data communication chain
• Scenario questions about troubleshooting RF issues in a remote work environment

Common mistakes to avoid

• Submitting generic applications that don't mention Planet's specific satellite projects or mission
• Focusing only on theoretical knowledge without demonstrating practical application of RF concepts
• Failing to address how you'll manage part-time remote work effectively while being a student
