About Us
One team. Global challenges. Infinite opportunities. At Viasat, we're on a mission to deliver connections with the capacity to change the world. For more than 35 years, Viasat has helped shape how consumers, businesses, governments and militaries around the globe communicate. We're looking for people who think big, act fearlessly, and create an inclusive environment that drives positive impact to join our team.
What You'll Do
We are seeking an experienced RF Engineer with deep expertise in frequency synthesis to contribute to D2D and future payload architectures. This role delivers hands-on engineering in PLL design, VCO development, and low phase noise reference oscillator systems, including vendor oversight and clock distribution. The position operates with limited supervision on defined RF programs and applies strong technical judgment to ensure design, integration, and performance success.
The day-to-day
Design and develop frequency synthesis architectures, including PLLs, VCOs, and low phase noise reference oscillator subsystems
Perform RF analysis, simulation, and validation to ensure compliance with performance requirements, including phase noise, jitter, and spectral purity
Lead schematic capture and design implementation for frequency generation and clock distribution circuits
Define and optimize clock distribution networks for low jitter and minimal coupling across RF subsystems
Provide technical oversight of oscillator vendors, including specification definition, performance evaluation, and qualification
Support integration of RF hardware with reference oscillator systems and spacecraft subsystems
Contribute to RF architecture trade studies, particularly around frequency planning, LO generation, and phase noise optimization
Interface with suppliers and manufacturing partners to support RF hardware production, validation, and component selection
Participate in RF design reviews, test readiness reviews, and anomaly resolution efforts
Identify RF performance risks (e.g., phase noise, spurs, coupling) and develop mitigation strategies
What You'll Need
Bachelor's degree in Electrical Engineering or related field, or equivalent professional experience
8 years of RF engineering experience supporting frequency synthesis hardware
Demonstrated expertise in PLL design, VCO design, and reference oscillator selection/integration
Strong experience with clocking systems, frequency generation, and signal integrity
Experience working with vendors and manufacturing partners, including oscillator suppliers
Ability to work independently on defined technical problems with minimal instruction
What Will Help You On The Job
Experience supporting spacecraft or payload RF frequency generation systems
Familiarity with reference oscillator integration and production environments
Deep understanding of phase noise, jitter, and frequency stability analysis
Strong analytical skills and disciplined documentation practices
Clear communication of complex RF and frequency synthesis topics to cross-disciplinary teams
Salary range
$141,500.00 - $224,000.00 / annually.For specific work locations within San Jose, the San Francisco Bay area and New York City metropolitan area, the base pay range for this role is $176,000.00- $264,000.00/ annually
At Viasat, we consider many factors when it comes to compensation, including the scope of the position as well as your background and experience.
