What is a Sr RF engineer?

Sr RF Engineers, or Senior Radio Frequency Engineers, are professionals who design, implement, and optimize wireless communication systems. They work with radio frequency signals and components to ensure reliable transmission and reception for applications such as cellular networks, satellite communications, and wireless devices. Their responsibilities often include system design, troubleshooting, network optimization, and compliance with regulatory standards. Sr RF Engineers typically have extensive experience and may lead teams or mentor junior engineers. They play a crucial role in advancing wireless technology and maintaining high-quality communications infrastructure.

What are the key skills and qualifications needed to thrive as a Sr RF engineer?

To thrive as a Sr RF Engineer, you need deep expertise in radio frequency engineering, signal processing, and wireless communication systems, usually supported by a degree in electrical engineering or a related field. Familiarity with RF simulation tools (such as CST, HFSS, or ADS), network analyzers, and relevant certifications like FCC or IEEE are typically required. Strong problem-solving skills, attention to detail, and effective collaboration set standout professionals apart in this role. These skills ensure reliable RF system performance, compliance with technical standards, and successful project delivery in dynamic technology environments.

What are some typical challenges Sr RF engineers face when managing large-scale wireless network deployments?

Sr RF Engineers often encounter challenges such as mitigating signal interference, ensuring optimal coverage in complex environments, and adapting designs to evolving regulatory standards. Managing multiple project timelines and coordinating with cross-functional teams—like network planners, field technicians, and software specialists—are also common aspects of the role. Effective problem-solving, strong communication, and staying current with RF technologies are essential to successfully overcoming these challenges.

What is the difference between Sr Rf Engineer vs RF Engineer?

AspectSr Rf EngineerRF Engineer
CredentialsBachelor's or Master's in Electrical Engineering, certifications like FCC or RF-specific coursesBachelor's in Electrical or Electronics Engineering, similar certifications often required
Work EnvironmentDesign, testing, and troubleshooting RF systems in labs or fieldSimilar environments, focusing on RF system implementation and testing
Industry UsageTelecommunications, aerospace, defense, wireless networksTelecommunications, consumer electronics, wireless communication
Role FocusAdvanced RF design, system optimization, technical leadershipRF system setup, testing, and basic troubleshooting

The main difference between a Sr Rf Engineer and an RF Engineer lies in experience and responsibilities. Sr Rf Engineers typically handle advanced design and optimization tasks, often leading projects, while RF Engineers focus on implementation and testing. Both roles require similar educational backgrounds and certifications, but the senior role involves more strategic and technical leadership in RF projects.

Senior RF Printed Circuit Board Layout Engineer

Array Labs

Redwood City, CA • On-site

$125K - $160K/yr

Full-time

Re-posted 24 days ago

Key responsibilities

  • Own RF PCB layout from initial placement through manufacturing release in Altium Designer

  • Define and implement stack-ups, controlled-impedance routing, and RF grounding, shielding, and isolation strategies

  • Partner with RF design, electrical, antenna, mechanical, and test engineers to develop layout constraints, run reviews, and de-risk first-pass success

Job description

Array Labs builds advanced radar systems to help humanity understand and respond to changes across the physical world. 
 
We're launching a coordinated fleet of radar satellites to create a high-resolution 3D map of the Earth - updated in real time - enabling faster, smarter decision-making for government and commercial organizations supporting disaster response, infrastructure resilience, and mission-critical geopolitical intelligence.
 
We design and build our satellites end-to-end, producing the world's most advanced earth observation satellites. Our fleet will deliver unprecedented levels of accuracy, coverage, and responsiveness to power critical insights precisely where they're needed most.
 
About the job
As a Senior RF PCB Layout Engineer, you will own the physical implementation of Array's RF and microwave electronics in Altium, translating schematics and performance requirements into layouts that work on the first spin. Your work will include component placement, controlled-impedance routing, stack-up definition, grounding and shielding strategy, connector and launch design, and isolation of sensitive RF and mixed-signal domains. 
 
You will partner closely with RF design, electrical, antenna, mixed-signal, mechanical, and test engineers to drive layout constraints, reviews, and manufacturing releases. The boards you ship will directly determine RF performance, stability, spurious behavior, and overall sensor reliability in the lab and on orbit.
 
Responsibilities
  • Own RF PCB layout from initial placement through manufacturing release in Altium Designer
  • Define and implement stack-ups, controlled-impedance routing, and RF grounding, shielding, and isolation strategies
  • Translate schematic intent into layouts that meet RF performance requirements, including connector launches, transitions, filtering, and protection circuitry placement
  • Partner with RF design, electrical, antenna, mixed-signal, mechanical, and test engineers to develop layout constraints, run reviews, and de-risk first-pass success
  • Drive DFM/DFT considerations with fabrication and assembly partners, including documentation and release artifacts
Basic Qualifications
  • B.S. in Electrical Engineering, or a related field with 4+ years of relevant experience
  • Experience in PCB layout, fabrication, and release of RF and/or high-performance electronics
  • Excellent teamwork and communication skills
  • Learns new concepts rapidly, completely, and in a self-directed manner
  • High levels of self-motivation and personal accountability
  • Ability to work in a fast-paced environment under significant time constraints
Preferred Skills and Experience
  • Experience designing RF and microwave PCB layouts including controlled-impedance routing, launches and transitions, grounding, shielding, and isolation
  • Comfort with Altium Designer for constraint-driven layout and clean manufacturing outputs; experience with Allegro and/or OrCAD is a plus
  • Experience developing PCB stack-ups and layout constraints for high-frequency, high-performance electronics
  • A strong intuition for layout-driven RF behavior, including coupling, return paths, leakage, spurious paths, and stability risks
  • Experience working closely with RF design engineers to translate schematic intent into layouts that work on the first spin
  • Experience with manufacturing release, DFM/DFT considerations, and collaborating with fabrication and assembly partners
  • Experience supporting lab bring-up and RF characterization alongside design and test engineers (e.g., helping troubleshoot issues seen on VNAs, spectrum analyzers, and in system testing)
  • Experience with EM and RF analysis workflows for layout validation (e.g., HFSS, CST, ADS Momentum) is a plus
  • Experience taking RF hardware from prototype through qualification and environmental testing
