BLOCK21 Recruitment

BLOCK21 Recruitment is a specialist engineering search firm dedicated to placing technical talent that shapes product development, infrastructure, and long-term business trajectory. With over 8 years of experience in engineering recruitment, the company works exclusively with technical startups and scale-ups to identify and place software engineers, platform engineers, mobile engineers, security engineers, ML/AI engineers, data engineers, and technical leadership roles including VP Engineering, Head of Engineering, and CTOs. BLOCK21 Recruitment distinguishes itself through a retained, exclusive search model that prioritises quality over volume, ensuring every introduction is intentional and aligned with the client's product and engineering culture.

The company specialises in recruiting across three core sectors: AI, Developer Tooling, and Emerging Technology. Within these verticals, BLOCK21 Recruitment places engineers across multiple disciplines including technical GTM roles such as Solutions Engineers, Forward Deployed Engineers, and Technical Account Managers. The firm maintains a direct network of passive talent across Europe and North America, combining traditional headhunting with proprietary market intelligence on funding rounds, team movements, sector momentum, and real-time compensation benchmarks. Rather than relying solely on LinkedIn, BLOCK21 Recruitment leverages 8+ years of on-the-ground relationships to identify the strongest engineering talent who are rarely visible on public job boards.

Based in London, BLOCK21 Recruitment operates across Europe and North America, serving technical companies at seed stage through Series C and beyond. The company's approach is built around each client's business rather than a standardised process, mapping technical stack, team structure, hiring bar, and compensation expectations before any outreach begins. With a track record of 90% of placements remaining in role at 12 months and an average of 11 days from CV submission to signed offer, BLOCK21 Recruitment has established itself as a strategic extension of leadership teams seeking to accelerate their technical hiring.
