Jonathan Speller

Jonathan Speller
Director, Chi Square Economics
LinkedIn

Jon founded the company in 2015 after graduating with a law degree and spending 4 years in another specialist recruitment company.

He specialises in the economics markets and helps his clients to hire expert economists particularly with competition, regulatory and policy backgrounds. His experience ranges from unique one-off searches, to helping firms attract a team of economists as part of a retained search.

When he’s not in the office, Jon can be found at the Tottenham Hotspur Stadium cheering on Spurs, walking his dog Neville, or flying around the UK in a PA-28 as he works towards his private pilot’s licence.

To discuss your next career move or hiring an economist, you can reach Jon on +44 7940 464440 or jspeller@chisquare-econ.com.

Demetrious Vassiliou

Demetrious Vassiliou
Director, Chi Square Analytics
LinkedIn

Demetrious started Chi Square Analytics in early 2017 after taking a career break to backpack around South East Asia.

Starting his career in IT, he moved into the world of specialist IT recruitment in 2012 and being a ‘techy’ at heart allowed him to understand the market to a high level. How many other recruiters can say they have built an SSRS server from scratch?!

Demetrious now specialises in data science and AI recruitment, helping his clients to build their data science and engineering teams.

When he isn’t on LinkedIn, you can find him taking pictures of Bear his fluffy Pomeranian, or singing “what you think of Tottenham?” much to the annoyance of Jon. He also plans to tackle an Ironman 70.3 in 2020 after completing his first Olympic Triathlon.

You can reach Demetrious on +44 7506 115453 or dvassiliou@chisquare-analytics.com.

Emmanuel Oloko

Emmanuel Oloko

Director, Chi Square Analytics
LinkedIn

After graduating with a bachelor’s degree in Information Technology, Emmanuel started his recruitment career in 2015 as a ‘DevOps Ninja Recruiter’. He then climbed up the ranks as a ‘DevOps Sensei’ and in 2017 joined Chi Square Analytics to become the Director for DevOps & Cloud.

Now with over 4 years of experience recruiting in the DevOps space, Emmanuel has built a strong network of clients across Europe, U.S and Asia.

When he isn’t contemplating which footwear to buy next, you could catch him enjoying a nice pint of Guinness, smiling/crying about Arsenal FC, or taking really interesting photos with his Nikon DSLR; all at the same time of course.

You might say having around 100 pairs of trainers is a bit excessive, although Emmanuel says it’s called being a ‘SneakerHead’.

To discuss any DevOps recruitment needs for yourself or to build out a team, please contact +44 7546 110052 or emmanuel@chisquare-analytics.com.

Pam Sohal

Pam Sohal
Director of Strategy and Operations
LinkedIn

After completing her law degree and LPC, Pam travelled around the US and eventually spent a year being a New Yorker. Moving back to the UK, she continued working for a global association focusing on strategy, membership, and business development, and most recently worked for an education start-up.

When she is not busy with Chi Square, it is often hard to keep track of Pam. If she’s not on a train somewhere in the UK, you will find her with friends and family (often in multiple countries), cooking, planning events and trips, or forcing everyone to watch her new favourite Netflix series and finding the latest hotspot for food and drink. This will be the year that she finally does something fitness related (maybe…).

You can reach Pam on +44 7725 136674 or psohal@chisquare-group.com

Marnie Pili

Marnie Pili
Resourcer, Chi Square Economics
LinkedIn

With a degree in Media and Communications, Marnie always had a keen interest in sales. She joined a world leading recruitment firm in early 2019 focusing on electrical and mechanical engineers in the German market, and has since joined Chi Square Economics where she is focused on recruiting regulatory and competition economists across Europe.

When she isn’t working too hard after working hours, you will probably find Marnie in the gym, theatre, spending time with her family, boyfriend & friends, at church, or somewhere around the world (…particularly somewhere hot!)

To discuss your next career move or to hire an economist, you can reach Andrew on +44 7861 492543 or mpili@chisquare-econ.com

Bear

Bear is a 2-year-old Pomeranian born and bred in Guildford, now living the South London dream.

She is proficient in licking potential candidates on the morning commute as well as having an Instagram following of over 10K. www.instagram.com/excusemypom

Regularly featured on LinkedIn, Bear is a force to be reckoned with for networking and organisation (of squeaky toys). She enjoys long walks to brunch and loves nothing better than keeping the rest of the team energised with regular trips to the park.

Neville

Nev has been a permanent fixture of the Chi Square office from day one. He gets no greater pleasure than pestering everyone in the office with his many tennis balls, constantly asking for food, or waiting for his next walk.
