At CesiumAstro, we are developers and pioneers of out-of-the-box 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’re looking for builders, problem-solvers, and system thinkers. We are seeking a Senior Communication System Integration and Verification Engineer I to support the end-to-end integration of communication functions for our communication payload products. This highly technical role combines deep domain expertise in communication systems with hands-on integration and test execution.
You will play a critical role in the architecture definition, execution, and delivery of our communication payload products—contributing to requirement definitions, algorithm development, Special Test Equipment (STE) design, verification, and final sell-off. This position is ideal for an engineer passionate about solving complex integration challenges and advancing the standard of excellence in payload delivery.
JOB DUTIES AND RESPONSIBILITIES
Responsible for lab and equipment management and guiding key equipment purchase decisions.
Core day-to-day responsibilities include collaborating with design and test engineering teams to develop test requirements, mapping requirements to reusable test architectures and procedures, architecting RF and digital test systems, implementing test plans and procedures, executing verification/validation tests, and logging and presenting results to key stakeholders.
Work closely with design teams to verify and evaluate expected system level performance
Ability to draw insightful conclusions from test results and troubleshoot system level anomalies for the purpose of providing feedback to design and verification teams
Ability to adapt test plans based on capabilities of HW/SW delivered by the design teams, compatibility with third-party systems, customer-furnished equipment (CFE), subsystem vendors and availability of the testing equipment.
Support the definition and development of Special Test Equipment (STE) required to verify communications payloads, and coordinate with Test Product teams for execution.
Represent the payload integration effort in program reviews, technical interchange meetings (TIMs), and formal sell-off events as a technical contributor.
Working in a startup environment and are passionate about developing critical test systems for leading-edge satellite communication systems.
JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS
Bachelor of Science (BS) degree in Electrical Engineering, Communications Engineering, or related technical field
4+ years of experience in communications systems engineering, payload integration, or systems development in aerospace, defense, or space environments.
Hands-on experience with lab instruments such as digital oscilloscopes, multimeters, source measurement units, RF signal generators, spectrum analyzers, vector network analyzers, bit-error rate (BER) testers and vector signal analyzers.
Hands-on experience in developing hardware and measurement abstraction layers, and test automation setups using basic scripting and SW development with common programming/scripting languages (Python, MATLAB, C/C++, etc.).
Understanding of RF and mixed-signal hardware (e.g. amplifiers, filters, ADCs/DACs, antennas) and its effect on test design.
Proficient in performing RF measurements and data analysis including S-parameters, AM/PM, compression, noise figure, harmonics/spurious emission, phase noise, switching speed, bit error rate, adjacent channel power, linearity, EVM and group delay.
Proven expertise in troubleshooting, fault isolation, and test execution skills at the unit, subsystem, and system level.
Hands-on experience with designing test setups in anechoic chambers for antenna systems evaluation.
PREFERRED EXPERIENCE
Master of Science (MS) or higher degree in Electrical Engineering, Communications Engineering, or related technical field
Knowledge of satellite and wireless communication systems and protocols
Familiarity with phased array antenna architectures and array calibration
Strong debugging skills in Communication system engineering involve a mix of systematic techniques (reproduce, isolate, hypothesize, test), deep system understanding, proficiency with tools (debuggers, logs, profilers, static analysis), and crucial soft skills like patience, communication and analytical thinking to efficiently find and fix root causes in complex systems.
