About Me.
Simon O'Neill.
With recruitment experience at Lloyds Register, Meridian Business Support, Elite Care 24/7, 3D Personnel, Interserve, Randstad Sourceright and Compass Group UK & Ireland, I've partnered with clients and candidates across a wide range of industries — enough to know a good hire is about more than what's on the CV.
I founded JamSim because executive recruitment had become too transactional. Too many candidates felt like CVs. Too many clients were rushed into hiring. I wanted conversations before placements, honesty before commission, and relationships that last.
Outside work, you'll find me baking — my banana cake has a loyal following — or on the sidelines scouting talent in women's football. Spotting potential and helping people go further is what I do, on and off the clock.

Our founding vision
I founded JamSim because I believed executive recruitment had become too transactional.
Too many candidates felt like CVs.
Too many clients were rushed into hiring.
I wanted to build a consultancy where conversations came before placements, honesty came before commission and long-term relationships mattered more than targets.

The JamSim difference: personal connection
We take the time to understand both sides — aspirations, working style, values — so every match is built for the long term, not just the next vacancy.

More than just a placement: a family
After working with JamSim, we want both businesses and Executive Assistants to feel a profound sense of belonging and support—like part of a family. Our goal is to forge enduring connections, where every placement feels like a natural extension of your team, contributing to a collaborative and successful environment. We believe strong partnerships are built on trust, mutual respect, and shared growth.
Professionalism in every partnership
At JamSim Executive Assistant Recruitment, professionalism is the cornerstone of everything we do. It guides our meticulous matching process, our ethical standards, and our commitment to excellence for every client and candidate we serve.
