RF Engineer

Overview:
Half the world still doesn’t have stable Internet – want to play a critical role in changing that? Beamlink helps carriers, ISPs, and local governments expand cell service with a new network architecture of lunchbox-sized cell towers. These cell sites, called Bentocells, address the historic bottleneck preventing carriers from expanding beyond cities. Our dynamic and trailblazing engineering team designs these in-house and the firmware, software, and network architectures that make them shine. Join us today!

Role Description:
We are looking for an electrical engineer with expertise and experience in RF design. You will play an integral role in the development of a cellular base station RF system. You will have the opportunity to contribute to every design stage, including defining system requirements, high-level system design, component selection, circuit simulation, circuit design & PCB layout, performance testing, and device certification.

Responsibilities:

• Design embedded RF circuitry, including integrating amplifiers, filters, duplexers, and other RF devices onto PCBs
• Design schematics and layout microstrip designs for new PCB designs and modify existing RF board designs
• Explore new techniques for cellular frontend amplification and filtering at broad frequency ranges, sub-6GHz.
• Support pre-compliance and 3rd party certification testing for radio equipment using requirements like FCC, CE, and RED.
• Derive top-level specifications for RF links
• Analyze antenna systems, including estimating antenna performance and configuration
• Troubleshoot RF issues from the board level to the system level
• Design beamforming antenna technology using Matlab models and implement it into prototypes
• Operate test equipment such as spectrum analyzers and waveform generators in a lab setting

Required Qualifications:

• Previous experience and knowledge in reading electrical schematics, BOMs, PCB layouts, assembly drawings, gain pattern graphs, and technical documentation/datasheets
• Experience with selecting RF devices, including antennas by balancing various criteria, including cost, schedule, and capability
• Experience with PCB Design, preferably Altium Designer
• Experience with digital signal modulation types and cellular waveforms (E-UTRA, 5G-NR)
• Basic knowledge of RF principles (signal strength, EVM, noise, frequency bands, propagation modeling, signal analysis)
• Additional Preferred Qualifications:
• 2+ years of experience working with RF circuitry, including work from top-level system design to PCB implementation to physical testing and product implementation
• Experience with LTE and/or 5G specifications such as 3GPP TS136.104
• Experience with interfacing with testing labs and RF compliance agencies
• Experience in sending devices through certification (FCC, CE, RED), and implementing design changes based on the results
• Experience in designing an RF link budget and validating it based on real-world data collected
• Experience with basic programming languages, including Python
• Experience in testing a product end-to-end

Salary/Benefits:

• Flexible work schedule with access to overtime pay
• Competitive salary commensurate with relevant experience
• Stock options
• Unlimited Paid Time Off
• Health Insurance
• Commuter Benefits
• Hybrid with access to additional flexible workspaces
