Jordan Mackellar
Chief Executive Officer
Jordan is the co-founder and Chief Executive Officer of PTSL.
His career in probecards started at age 17 through Motorola Scotland’s apprenticeship scheme. During this time, Jordan studied Electronic Engineering at Glasgow Caledonian University. Jordan transitioned to his first role at probecard manufacturer K&S in 2003. Initially employed as an Applications Engineer, he was quickly promoted to Engineering Manager for Europe.
Jordan always had a passion and burning desire to create high-value jobs that would utilise the talent in Scotland, throughout Europe, and globally. He and company co-founder Gordon Stirling met at a church breakfast in 2009 and PTSL was conceived months later. The goal was to build a probecard company where the values and ethos married with their Christian faith.
Today, Jordan is well known in the semiconductor test field, and is exceptionally proud of what the PTSL team has achieved in just over a decade. He and the team share a passion for delivering exceptional service to the customers, and if Jordan isn’t on the road visiting customers, he can be found in the R&D department relentlessly committed to the technologies that are shaping PTSL’s exciting future.
Jordan lives in Scotland with wife Laura and four kids. Outside of work, he enjoys spending time with family, exercising, and is a big car enthusiast.
