Senior System Test Automation Engineer (Test Automation Framework Developer) at Skylo Technologies ,Palo Alto, CA

Skylo Technologies is developing the most affordable and accessible wireless network to mobilize the world’s machine data. A spin-out from the Stanford Space Systems Laboratory, Skylo is commercializing very low cost satellite gateways and a highly efficient satellite network protocol that is 1 to 2 orders of magnitude less expensive than traditional satellite communications. Skylo’s network will form the core connectivity fabric for billions of machines and sensors across the globe. Backed by SoftBank, Innovation Endeavors, DCM, and Boeing, Skylo’s global team includes professionals with deep experience in wireless networks and hardware, satellite technology, and applied IoT data services. Skylo's network is operational in California and India in preparation for a global launch in 2020.

Skylo is hiring a Senior System Test Automation Engineer (SDET) to implement a robust automated test and QA environment and process to ensure that our end-to-end system exceeds customer expectations with every release. The Senior System Test Automation Engineer will join our System Test team and play a leading role in all aspects of system verification (hardware, software and firmware) of a carrier-class wireless network, low-cost terminal device and data analytics platform to support the next generation of machine & sensor data mobility. This individual will leverage a strong background in wireless telecommunications, SaaS testing and test automation. This is a fantastic opportunity for someone with a passion for quality and a minute attention to detail who is interested in participating in building a verification platform from the ground up, and seeing their work have global impact across industries.


  • Work closely with the hardware, firmware, LTE base station/core, network and platform engineering teams to develop and execute system acceptance testing that will verify end-to-end functionality prior to each release of the Skylo NB-IoT system. The process may start with a combination of automated and manual testing but must rapidly progress toward fully automated regression testing.
  • Develop and implement a plan to transition to an automated subsystem and system verification environment to enable quick identification of any regressions during development and to enable a complete range of functional and regression testing
  • Develop software code and automated tests that are maintainable and reusable.
  • Develop test automation framework using one or more frameworks Robot Framework, NUnit,, PyUnit / unittest, Junit, Test::Unit., RSpec
  • Develop test automation scripts using Java, Python, Go or Ruby.
  • Select and implement appropriate testing tools, including a combination of off-the-shelf tools and in-house developments, in coordination with the core engineering teams
  • Write and execute test plans and procedures which, in conjunction with sub-system testing, will validate the full functionality of the Skylo NB-IoT system against our established Product Requirements Documentation
  • Quickly identify and characterize system functional issues , bugs and work with engineering to prioritize and validate fixes
