About the Company

Simon James IT is an international specialist IT consultancy based in the City of London.

Coming from successful consultancy backgrounds we have taken the positive elements of large scale recruitment and built a business model to provide a personalized solution for your recruitment needs. We offer a dedicated service to ensure you get the best possible candidates within both your timescales and budget.

Our business has grown organically from building solid foundations within niche technology areas and working closely with organisations. Through success our client base developed and in turn our business evolved with them, to supply a wider range of technologies and skills across multiple sectors.

Across the years we have had a number of these clients ask for a more in depth service which would have taken us away from the tailored solution that has made us successful. With this in mind we have created SJ Infrastructure & Technology Services, our independently managed consultancy arm to provide outsourcing for larger projects to meet our client's needs. This allows us to still concentrate on our core business as a specialised IT recruitment function.


Established in 2006 we rapidly created a reputation for providing high quality candidates to a wide range of business sectors whilst remaining a boutique, tailored, personal service.

Solely owned and managed by the Directors we guarantee the needs of both client and candidate are not only met but exceeded.
