I’ve been in the computer business since 1968, when I went to the United Kingdom Atomic Energy Authority to spend a year before going to university. After undergraduate and postgrad stints at Essex and Newcastle, I worked on distributed systems and databases in the UK. In 1981 I moved to the Boston area, and four years later I joined Sun Microsystems. After twenty years with Sun, I moved to Seattle with Amazon.com, and in 2009 I finally arrived in Silicon Valley, where I’ve worked on cloud computing architecture for Huawei Technologies, Yahoo! and Brocade. I also spent a year as an Entrepreneur-in-Residence at US Venture Partners. During 2014-2015 I was the OpenStack architect in Cisco Cloud Services, working on the now-defunct Cisco Global Intercloud initiative. And in November 2015 I joined Sensity Systems as Chief Technology Officer
Most of my technical work has involved programming languages, network protocol design, and distributed computing, especially computing at large scale. However I’m also interested in the issues of engineering culture, and how these affect distributed teams and software engineering methodologies.
For conferences and other events requiring a capsule bio, I generally use this:
Geoff Arnold is the CTO of Sensity Systems, an IoT startup developing a cloud based sensor platform that leverages lighting systems. He’s been a software engineer in the UK and US for 47 years, during which time he’s worked on two distributed operating systems, a DBMS, the first NFS for PCs, a Java PaaS, two Unix workstation OSs, economic modeling systems for the UK Treasury, the control system for a nuclear reactor, distributed AI, the WinSock TCP/IP API, and two IaaS clouds. (He’s also been a systems programmer, a consultant, an Entrepreneur-in-Residence, and managed two business units.) For the last 10 years, he’s been immersed in cloud computing for companies like Sun Microsystems, Amazon.com, Huawei, Yahoo!, Brocade, and Cisco. He blogs on cloud computing at http://speakingofclouds.com, and Tweets as @geoffarnold.
