Open Source Group Ltd

I had the opportunity to work with Harry on recruiting Data Analysts and Data Engineers for our data team. Harry consistently found me talented candidates who were a great fit. The recruiting process and our cooperation were always smooth and pleasant. Highly recommended!

Really enjoyed working with them throughout the whole process. They were always helpful and easy to deal with, and helped me land a new role.

George is outstanding and very professional, he takes a very human approach to recruiting.

Working with Harry and OpenSource was a great experience from beginning to end - they perfectly matched me with my new job, helped fight to get me the compensation for it that I deserve, and we had fun doing it! I met Harry in early 2025 (just on the cusp of AI sloppifying the labor/recruitment market), I was already employed as a devops engineer elsewhere, but I was looking for something new via both recruiters and the jobs boards. Harry connected with me on LinkedIn with an engineering job (senior oncall engineer, devops/SRE at a fintech firm) that was incredibly well suited for me on all fronts: skills match, industry match, leveling/compensation match, and geographic match (at the time I was living and working in the US, and Harry presented me with an opportunity that was flexible and workable from both the US and the UK) We met for a quick intro over Zoom, Harry was super nice, accommodating, friendly and cool, and he knew what he was talking about - a true professional! We discussed the job, my fit, my interest, my comp expectations, and Harry communicated all this back to the employer - and clearly quite well!! Something I really appreciate about Harry and everyone at OpenSource Recruitment: since our initial meeting, several months went by with no word from the employer. A lesser recruitment firm probably would have dropped the ball, forgotten about me, or moved on, but Harry & co stayed on the case with me, communicated proactively, and got me into interviews a few months later as soon as the employer was ready to engage. After passing all my interviews and entering into the compensation negotiations phase, Harry and OpenSource absolutely came in clutch. Harry helped me negotiate a significantly higher salary than was originally discussed, putting me at the top of the comp band for the position; Harry and OpenSource advocated for me and worked as my liaisons to the employer - having them there to back me up was essential, and I don't think I could have pulled it off without them! Harry and OpenSource are the recruitment GOATs, and whenever I'm looking for new work I will be hitting them up again - highly recommend!!

I had a great experience working with Harry. He always supportive and easy to talk to. What really stood out was that he continued to check in even after I started my new role. I’m really grateful for all his help and would highly recommend him to anyone looking for their next opportunity.

Working with OpenSource recruiting team especially Harry was a great experience - they were responsive, understood exactly what I was looking for, and made the whole process smooth and professional. Highly recommend!

George is amazing, really understands your needs and be on top in getting the right candidate for the job. George is always go to person.

I had a great experience working with George throughout my recruitment process. He was professional, responsive and genuinely attentive from start to finish. The whole process was well-organized, and I really appreciated his personal approach along the way. Many thanks!

I have worked with Harry and the OpenSource Recruitment team from both sides of the table - first as a candidate, and later as a hiring manager seeking top-tier cybersecurity and tech talent. They consistently understand complex technical requirements and deliver precise candidate matches. Many of our most critical senior hires have been sourced through their agency. I highly recommend them as a reliable and highly effective recruitment partner.

I had a great experience with Opensource Recruitment, especially thanks to Harry, who made me feel supported throughout the entire recruitment process. I expecially appreciated staying in touch even after the placement, which made the whole experience feel genuinely personal and supportive. Highly recommended
