Senior Systems Engineer

In a Systems Engineering role at Tarana you will be working on all aspects of our next-generation Fixed Wireless Access products (ngFWA).  We develop both the base stations, CPE, and cloud management tools for a complete solution to FWA providers.  System Engineers are involved at the individual device level (base station or CPE) but also the link level, sector/cell level, and network level.  This spans from low-level front-end RF and calibration through PHY and MAC layer, switches/network interface, and sector and network design and optimization.  Tasks range from simulation and analysis of new features/products to hands-on testing and bring-up of new hardware and to analyzing and conducting experiments on real customer deployed systems and whole sectors and networks.  We are a fast-paced company with many opportunities to learn, grow, and have a big impact.

A successful candidate will be able to:

• Play a significant role in developing new features
  • Identify areas for system performance improvement in line with business and customer use cases and product road maps
  • Document proposed feature and support expected performance or justification for feature with analysis, simulation, and lab/field test data
  • Present feature to team/developers and iterate on architecture/algorithm based on developer feedback and implementation/platform limitations
  • Provide simulation results/test vectors for developers to use for implementation verification
  • Design tests and procedures and communicate expected results to testers
  • Work with field support team to follow up with design implementation once deployed to verify correct performance in the real world
• Design tests to verify feature/sub-system performance
  • Identify requirements and comprehensive corner cases that need to be verified
  • Manually run systems tests to prototype procedures, demonstrate expected results, and provide detailed procedure or test techniques and expected results to the automation team
• Support debugging and root cause analysis efforts of performance shortfalls
  • Help with test data analysis and manual testing of systems in lab or field to diagnose sources of bugs
  • As an expert in the system (or at least a representative of the systems team), provide detailed instructions/ideas for support and test groups to focus on in the debug efforts
  • Run existing or create new simulations to help in the debug effort
  • Work with developers during software release/integration to test proposed fixes and provide feedback and detailed ‘steps to reproduce a bug’
  • Be able to take system-level behavior and identify possible root causes or subsystems that could be at fault.  Suggest tests to isolate which piece of the system may be the issue.  Manually run tests on the system to do the above.
  • Be willing to ‘own’ a problem, even if you aren’t an expert in that particular piece.  Proactively search out experts and necessary knowledge to support the effort. 
• Develop ‘hands on’ capability to run systems in the lab and characterize different aspects.  Be able to quickly (w
