We are designing, building, and launching 8 new satellites in the next four years. They are BIG and super capable RF payload rideshare SmallSats. Our launches are already secured. Our in-house test facilities are built. If you want to own critical communications for these LEO communications satellites and then have the chance to iterate and improve your design at a rapidly growing tech company, this is your chance.
We're looking for builders, problem-solvers, and system thinkers. As a
Senior Spacecraft Communication Systems Engineer, you will own the design, configuration, and operation of the satellite's space-to-ground communication links. You will define how the satellite communicates with the ground in both nominal and off-nominal conditions, ensuring reliable command, telemetry, and fault recovery.
The ideal candidate will have a strong background in systems engineering, expertise with both space-based communication payloads and ground terminals, and proven ability to coordinate activities across multidisciplinary engineering teams.
JOB DUTIES AND RESPONSIBILITIES- Model, analyze and maintain the satellite's link budget, modulation and coding, ensuring reliable communications from space to ground for all RF links.
- Architect hardware-based crypto solutions for flight hardware, manage pass-throughs and end points for users and operations.
- Strong understanding of ground station and network operations with the ability to troubleshoot issues with commercial providers and on-site terminals.
- Define how the radios are used in different mission phases, including contingency operations and emergency recovery.
- Contribute to the RF link test campaign and work with flight software and ground teams to validate end-to-end communication link performance, from antenna to command center.
- Optimize low-SWaP communications, mitigate interference, and ensure robust, fail-safe links.
WHAT A SUCCESSFUL CANDIDATE LOOKS LIKE- You understand how to design, analyze, and operate spaceborne communication links.
- You can balance power, bandwidth, protocols and noise to ensure reliable space-to-ground connectivity. You can answer "what's the link budget" with thorough analysis, EbN0, EsN0, or effective data rate given a variety of conditions.
- Extensive and practical experience with crypto-From COMSEC plan development, key management to system trouble shooting you have applied, on the ground experience.
- You know how comms fit into the broader mission, from flight software integration to ground operations
- You are comfortable identifying problems and using your expertise to find solutions.
- You can prototype, test, and iterate quickly, focusing on what's needed to get a mission off the ground.
JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS- Bachelor's degree in electrical engineering or a related field
- A minimum of 6 years of experience with emphasis on satellite communications, RF system engineering, or related fields
- Experience in design, verification, and operation of satellite communication links
- Strong understanding of link budget analysis, modulation schemes, and ground station interfaces
- Hands-on experience configuring and testing ground station equipment and space-qualified radios and antennas
- Practical understanding of how space links fail, why, and how to fix them before they break
- Ability to define and implement communication system CONOPS for nominal and emergency operations
- Experience with satellite communication link licensing and regulatory compliance (ITU/FCC)
