RF Engineer Senior

York is seeking a Senior RF Engineer to lead and deepen the technical integration of spacecraft RF communication systems. You will partner with internal teams and external vendors to architect high-reliability RF solutions, guide link-budget assessments, and ensure communication performance that scales with York's high-tempo production environment.

This is a senior-level systems-integration role, not a component-design position, focused on leading the technical direction of vendor-provided RF hardware, overseeing advanced performance validation, and ensuring resilient, high-reliability communication links throughout spacecraft development and on-orbit operations

This role will be fully on-site in our Greenwood Village, Colorado office.

Responsibilities

• Lead systems-engineering development activities for RF subsystems across proposal, development, integration, test, and on-orbit phases.
• Drive implementation of robust, cost-effective RF communication architectures that enable manufacturing at scale.
• Own RF component specification development for compliance with spacecraft configuration and customer requirements.
• Serve as a senior technical resource for RF physics, communication theory, and link-budget methodology.
• Validate waveform compatibility and support root-cause analysis for on-orbit link issues.
• Lead requirement decomposition and allocation activities for RF systems.
• Develop, maintain, and present systems-engineering artifacts for major program reviews (SRR, PDR, CDR, TRR, PSR).
• Drive enhancement of RF link analysis tools and lead new modeling initiatives.
• Perform antenna co-interference simulations using advanced 3D EM tools.
• Support AIT through evaluation of non-conformances, master test plan reviews, and as-run analysis.
• Travel as needed to support testing campaigns and launch operations.

This role will not have direct reports.

Required Qualifications

• Bachelor's degree in Electrical Engineering, RF Engineering, Wireless Communications, or related discipline.
• 4+ years of experience in RF engineering or RF systems integration.
• Ability to independently perform space-to-ground link budget analysis.
• Advanced understanding of analog RF components and digital communication systems.
• Hands-on experience with design, development, and/or testing of RF communication systems.
• Familiarity with satellite standards such as CCSDS and DVB-S2.
• Proficiency in Python scripting and Git.
• Detail-oriented, accountable, and collaborative in a fast-moving engineering environment.
• U.S. Citizenship.
• Ability and willingness to obtain and maintain a U.S. Secret security clearance.
• Willingness to work full-time in office in Greenwood Village, CO.

Preferred Qualifications

• Familiarity with RF test equipment (VNAs, spectrum analyzers).

• Active U.S. Secret security clearance or higher.
