Job description

Meet the Team As a global technology leader, Cisco has been transforming how people connect, communicate, and collaborate for decades. Our innovation in networking, security, and cloud-based solutions enables organizations to drive digital transformation and achieve their business goals. The Collaboration Employee Experience organization creates workspace solutions that connect people, places, and experiences. Located in Galway, Ireland, you will be part of our engineering team, working closely with colleagues both locally and as part of a wider international team spanning Oslo and the United States. You will work closely with Cisco’s Devices organization — a team of 300+ passionate engineers across hardware, software, mechanics, audio, media processing, and artificial intelligence — from concept to product. Together we strive to create best-in-class video conferencing experiences by bringing diverse engineering disciplines under one mission.

Your Impact

You are a senior software engineer who enjoys working across the software stack, from low-level Linux and Android platform development through to integration and debugging. You thrive as part of a team and contribute to our culture of shared learning, yet you are equally comfortable taking ownership and figuring things out independently when needed. You will be a technical anchor on Android platform work — designing, building, and optimizing Android environments that run our core communications software on Cisco collaboration devices.
