Built on deep understanding of technical markets
Onyx was created to serve the technical and future-focused parts of the market , the roles and disciplines that sit across architecture, engineering, infrastructure, renewables, and the broader built environment.
We work with consultancies, developers, contractors, asset owners, energy businesses and project-driven organisations that need high-quality people in specialist roles.
As part of a wider group of specialist recruitment brands, Onyx exists to bring sharper positioning and deeper market focus to technical hiring. Rather than trying to cover everything, we focus on the markets where industry understanding, role clarity and long-term fit matter most.

Why Onyx
We don't just place people. We match talent to projects that are shaping what comes next. Every brief we take on starts with understanding the work, the team and the kind of person who will thrive in that environment. It's a slower, more deliberate approach, but it's why our placements stick and our clients keep coming back.
Environmental and sustainability
Consultants and specialists embedding sustainability into every project.
Energy & Renewables
Solar, wind and energy specialists powering the transition to a more sustainable built environment
Deep sector knowledge
We live in these markets every day. We understand the technical demands, project timelines and commercial realities that shape how teams are built. That means we can speak your language from the first conversation and deliver candidates who genuinely fit the work.
Consultative hiring
No templates. No shortcuts. We take the time to understand your business, your team dynamics and exactly what success looks like in the role before we present a single candidate. It's recruitment built around listening, not volume.
Better outcomes
Placements that stick. Teams that perform. Careers that advance meaningfully. We measure our success by what happens after the hire, not just the offer letter, and that long term focus is what keeps our clients and candidates coming back.
