You will work closely with the product design teams, located in both Europe and the US, to interpret module requirements and turn them into corresponding test plans and test equipment requirements. You will work closely with systems engineering and manufacturing teams to ensure array performance meets specification across temperature, environmental stress, and production variation.
This is a site‑based role, employees work 3+ days (60%+) per week from a Viasat office or work location within a standard five‑day workweek.
The day-to-day
Architecture & Validation Strategy
Develop and maintain RF test architectures for active phased array systems
Define validation strategies for beamforming, calibration, and performance at unit and integrated‑payload levels
Test Solution Development & Automation
Design and implement test solutions for radiation pattern measurement, conducted RF validation, and over‑the‑air characterization
Develop automation software in Python or similar languages to control units under test, instrumentation, and data systems
Data Analysis & Troubleshooting
Analyze RF data to assess gain, linearity, noise performance, phase coherence, and beam steering accuracy
Drive root‑cause analysis of RF performance issues and provide design feedback to improve yield and robustness
Support environmental and qualification testing from an RF performance standpoint
Operate as a hands‑on engineer, moving between architecture discussion, detailed RF debug, and data‑driven performance analysis
Cross‑Functional Collaboration & Scalability
Interface with mechanical, digital, firmware, and manufacturing teams to ensure test coverage supports production scalability
Present performance results and technical trade studies to engineering leadership
What you'll need
8+ years experience in RF test and validation
Experience with space-based or high-reliability phased array systems (satellite, radar, or equivalent)
Bachelor’s degree in Electrical Engineering or equivalent experience
Deep understanding of antenna arrays, beamforming concepts, and RF signal chains
Strong experience with RF test equipment including spectrum analyzers, vector signal analyzers, vector signal generators, and network analyzers.
Strong experience with over-the-air testing (near field and far field)
Demonstrated experience architecting automated RF test systems
Experience troubleshooting complex RF systems and driving root cause to resolution
U.S. citizenship required
Ability to travel up to 10%
What will help you on the job
Demonstrated end‑to‑end ownership of complex test systems, from concept through deployment, with clear accountability for outcomes
Experience with active electronically steered arrays and digital beamforming architectures
Background in over-the-air (OTA) test methodologies and compact range or near-field measurement systems
Familiarity with calibration strategies for large scale arrays
Experience supporting environmental qualification testing of spaceflight RF hardware
Experience transitioning RF test solutions from engineering development to production environments
Ability to operate effectively in cross-functional, schedule-driven programs
