## Description

The candidate will need to demonstrate advanced knowledge of the individual cellular protocols, cellular network signaling, data session management, and backend analysis skills with TCP and UPD communications. Ideally the candidate will have sufficient experience to run basic database queries on SQL, developing scripting tools as needed for data analysis, and the ability to programmatically analyze large data sets.

This individual will responsible for investigating and troubleshooting/resolving end to end data communication issues, and determining the root cause of the failures, and work in conjunction with the hardware and software development teams to resolve these issues and confirm performance improvements.

Principal Responsibilities:

 * Maintain and troubleshoot end-to-end performance of real-time wireless monitors tracking cold chain shipments in Consumer Industrial, Food Industry and Life Science markets.
 * Work with hardware and software engineering teams to optimize integration of mobile devices with cloud based backend processing and databases.
 * Support initiatives across the hardware engineering organization to improve processes and drive cost reduction.
 * Work closely with the hardware engineering and the software development teams to identify and determine root cause of communication issues.
 * Document and manage the issue resolution process, with multi-functional teams, from identification to implementation validation
 * Build process and procedures to pass on and implement with more junior team members
 * Document change and improvement through the company's quality management program
 * Analyze wireless data packets and other data streams to detect issues
 * Cost reductions driven by automation/process improvements/alternate component approvals
