Location: Milpitas
Posted on: July 27, 2022

Job Description:

It is a super exciting time to join Tarana Wireless, as we are poised to disrupt the fixed wireless internet delivery ecosystem. Tarana is playing a vital role in closing the digital divide by providing a fiber-class wireless alternative to suburban and rural markets, as demonstrated through the tremendous success of our next-generation fixed wireless technology products. Years of R&D and prototyping have led to the successful commercial release of our G1 products built with custom in-house designed ASICs, RFICs and a proprietary protocol stack.Our ideal candidate for this position is a hands-on, self-driven RF systems expert with a good end-to-end understanding of wireless transceivers. In this role, you will drive characterization of our RF HW, optimize performance of G1 transceivers and influence technology and development of next-generation products. In addition, you will also be instrumental in the design and development of scalable test methodologies in our automated framework to quickly characterize board variants, identify trends and optimize RF performance with a goal of achieving the best product KPIs.JOB RESPONSIBILITIES:

  • Define target specifications of RF chains, and drive RF characterization efforts to meet the specifications.
  • Establish performance metrics and a process for efficient calibration of RF HW, execute on it with an eventual additional goal of improving manufacturing efficiency.
  • Identify and influence improvements to system performance.
  • Partner with modem system engineers, RF engineers, FW engineers and test engineers to optimize end-to-end system performance.
  • Provide systems engineering input to RF board design, schematics, and layout.
  • Establish an automated process via which boards get quickly qualified, board variations are identified and understood.
  • Develop an end-to-end system understanding of Tarana products and be able to diagnose RF and mixed-signal issues using observable results and metrics from product level tests and manufacturing tests.
  • Support test engineers to develop and refine an automation framework to characterize boards and extract relevant metrics for analysis.REQUIRED SKILLS AND EXPERIENCE:
    • PhD EE with 3+ years or MS EE with 7+ years of relevant experience
    • Strong foundation in wireless radio receiver/transmitter architecture, sampling theory and signal processing
    • Excellent understanding of RF impairments, their impact on transceiver performance and calibration / compensation techniques
    • Experience defining performance metrics and specifications, and optimizing performance from a standpoint of interference, phase noise, image rejection, co-existence etc
    • Good understanding of receiver state machines/control loops, associated algorithms and design trade-offs
    • Hands-on engineer and a problem-solver who can drive characterization, triage and enhancements to drive superior modem performance
    • Familiarity with lab equipment such as signal generators, spectrum analyzers, signal analyzers and network analyzers
    • Excellent analytical skills, communication skills and a go-getter attitude
    • Comfortable using python for instrumentation and automationPlus:
      • Experience with link budgeting (noise-figure, implementation losses), gain table design, calibration state machine design, PLL loop filter design for phase noise optimization, multi-radio coexistence etc
      • Experience productizing OFDM MIMO based wireless radio products, such as WiFi, LTE, 5G
      • RF board bring-up experienceSince our founding in 2009, we've been on a mission to accelerate the pace of bringing fast and affordable internet access - and all the benefits it provides - to the 90% of the world's households who can't get it. Through a decade of R&D and more than $400M of investment, we've created an entirely unique next-generation fixed wireless access technology, powering our first commercial platform, Gigabit 1 (G1). It delivers a game-changing advance in broadband economics in both mainstream and underserved markets, using either licensed or unlicensed spectrum. G1 started production in mid 2021 and has now been installed by over 160 service providers globally. We're headquartered in Milpitas, California, with additional research and development in Pune, India.G1 has been developed by an incredibly talented and pioneering core technical team. We are looking for more world-class problem solvers who can carry on our tradition of customer obsession and ground-breaking innovation. We're well funded, growing incredibly quickly, maintaining a superb results-focused culture while we're at it, and all grooving on the positive difference we are making for people all over the planet. If you want to help make a real difference in this world, apply now!
