communication systems for satellites, UAVs, launch vehicles, and other
space and airborne platforms. We take pride in our dynamic and
cross-functional work environment, which allows us to learn, develop,
and engage across our organization. If you are looking for hands-on,
interactive, and autonomous work, CesiumAstro is the place for you. We are
actively seeking passionate, collaborative, energetic, and
forward-thinking individuals to join our team.We are building, iterating, and getting to space fast. Our team thrives
on action. We leverage deep experience in the space industry with engineering
reimagined for speed and agility. We design, test, and deploy real systems
that fly. If you want to own critical communications for a satellite
mission, keep reading.We're looking for builders, problem-solvers, and system thinkers. As a
Principal Narrowband Communication Systems Engineer I, you will own the
design, configuration, and operation of the satellite's space-to-ground
TT&C systems. 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,
experience in space technology, and the ability to be the technical point of
contact for a major spacecraft subsystem. You will coordinate activities
across multidisciplinary engineering teams, raise issues at the program
level, and drive complex programs to success. We are looking for
independent, self-starters who are comfortable identifying problems and
using their expertise to pathfind solutions.
JOB DUTIES AND RESPONSIBILITIES
Own the RF Link - Model, analyze and maintain the satellite's link
budget, modulation and coding, ensuring reliable communications from space
to ground.
Select & Configure Hardware - Define and implement the TT&C radios,
antennas, and modems best suited for the mission.
Develop Operational Concepts - Define how the radios are used in different
mission phases, including contingency operations and emergency recovery.
Integrate & Test - Work with flight software and ground teams to validate
end-to-end TT&C performance, from antenna to command center.
Solve Hard Problems - Optimize low-SWaP communications, mitigate
interference, and ensure robust, fail-safe links.
JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS
Bachelor's degree in electrical engineering or a related field.
A minimum of 9 years of experience with emphasis on satellite
communications, RF system engineering, or related fields.
Expertise in design and operation of TT&C, S-band, and narrowband
satellite communications.
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.
Ability to define and implement communication system CONOPS for nominal and
emergency operations.
Understanding of how communication payloads fit into the broader mission,
from flight software integration to ground operations.
Ability to move fast to prototype, test, and iterate quickly, focusing
on what's needed to get a mission off the ground.
PREFERRED EXPERIENCE
Experience with software-defined radios (SDRs), CCSDS protocols, or
regulatory compliance (ITU/FCC).
