Organisations where professionals we work with have built their careers




























These logos identify employers of professionals supported by Eich Dyn and organisations from Dai Jones’s own engineering career. They are not Eich Dyn corporate clients and they do not imply endorsement of Eich Dyn or Career OS™.
Your experience should be creating opportunities, interviews and career choices.
If it isn't, the issue may not be what you can do — but how clearly the market understands your value.
Eich Dyn helps experienced professionals turn substantial expertise into a clear, credible and commercially relevant market position.
The work is delivered through Career OS™ — our proprietary six-stage system for career diagnosis, positioning, evidence, opportunity creation, interview conversion and offer negotiation.
We don't treat the CV, LinkedIn profile, job search, interview or negotiation as separate problems. We connect them to one career strategy.


When the next step requires a move.
For professionals changing employer, role, sector or career direction.

When the opportunity is to progress from where you are.
For professionals who want greater scope, responsibility, influence, reward or promotion without necessarily leaving their organisation or specialist field.

"Working with Dai has been hands-down one of the best experiences I've ever had for my development and progression. The toolkit he provides is unmatched — Truly incredible. I was blown away by the resources available."
