I had an outstanding experience working with Ian Tunnicliff from Colossus Recruitment. He was extremely professional and genuinely helpful throughout the entire process. Ian’s deep understanding of the software engineering industry was evident, and it made a significant difference in matching me with an opportunity that was the right fit. Communication was seamless — Colossus were always easy to get in touch with and quick to respond to any questions or concerns. I highly recommend Ian Tunnicliff to any software engineer looking for a knowledgeable and reliable recruiter!

Software Engineer
Just wanted to drop you a note to thank you for filling our Senior Engineer role. This role had been vacant for a number of months, we have used four other recruiters who had struggled to find any suitable applicants, but you managed to head hunt three and we now have a great hire. Thank you once again and we are now glad you are helping us to fill our other roles.
Managed Service Provider
I’ve been really pleased on how easy it is to work for Colossus Recruitment. The timesheet system is excellent, paid on time unlike other companies and a great service from agency.
Contractor
Very impressed with the speed and calibre of the candidate’s introduced to us following our request, and will certainly be using your services again in the future. Thanks once again for your help.
Financial Services Provider
I would like to say what an excellent service we have received from Colossus. We have dealt with multiple recruiters over the years that have never really understood our business and our needs. We have also employed a number of on-site recruiters who have also struggled. Since working with us you have taken the time to understand our business and offer a tailored solution which as meant we have recruited some great people.
