Job Description

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
