LTE System Integration Test Engineer

Engineering | Sunnyvale, CA | Full Time

Job Description

Company Location:  960 Hamlin Court Sunnyvale, California 94089


About Us

Kumu Networks is revolutionizing the way wireless systems are built using an innovative full-duplex wireless design that its co-founders developed in their research at Stanford. Wireless full-duplex allows a radio to transmit and receive signals at the same time using a single frequency channel. Kumu's patent pending full-duplex technology changes the basic assumptions on which current wireless radios are built, allowing for improved performance and reduced complexity across a variety of wireless devices and markets. Come help us change the future of wireless!

Description

You are a LTE enthusiast with experience bringing up, integrating, and testing LTE radios. You want to be a part of a team developing and deploying the world's first LTE wireless full-duplex relay. You will participate in the full life cycle of product development – from requirements definition and documentation, through test specification (hardware design and component selection), test implementation (hardware and software), product characterization and validation (test execution), issue analysis (triage), and debug. You will work directly with customers to bring-up, integrate, and validate our LTE full duplex relay in their network.

Responsibilities

The ideal candidate is above all a skilled LTE Systems Engineer with experience in characterizing and integrating UE’s with strong programming skills. You are comfortable on LTE system testers like the CMW500, can connect a UE to a Small Cell and EPC in the lab, and would love to automate the entire process in Python. You can relate TCP/UDP tput to PHY level parameters and have LTE channel numbers in your dreams. You are familiar with drive testing and channel propagation measurements.

You are able to interpret product requirements and derive engineering specifications and test plans from them. You have experience working on and qualifying LTE radio technologies in the lab, as well as supporting LTE radios in the field. You are fluent in at least one scripting language, and can prototype and develop repeatable and traceable tests. You are able to clearly discuss your plans, technical details, and results with a variety of other development teams.


Requirements

  • Experience designing and implementing LTE RF/wireless system validation tests (designing hardware with OTS components and test equipment, and writing the software in an Object Oriented and scalable manner).

  • Experience executing tests, analyzing data and reporting on LTE RAN system performance (ACLR, EVM, Sensitivity, Throughput, etc)

  • Experience debugging product and test setup issues (RF as well as network)

  • Detailed understanding of the operation and theory for spectrum analyzers, network analyzers, power meters, and other RF Lab equipment.

  • Experience reading communication system requirements and developing test and characterization plans from them.

  • Strong with at least one scripting language (Python preferred).

  • Clear written and spoken communication.

  • BS. degree or higher in EE or similar discipline

  • >5 years of relevant work experience (or MS. + 3years)

Bonuses

  • Experience with Nokio or Erikson small cells and/or Polaris EPC.

  • Experience will related software tools like GIT and CI testing.

Perks

  • Breakfast and lunch provided daily

  • Sunny, open, collaborative workspace

  • Opportunity to work with great people
