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
