Human Resource Administrator à Grande-Bretagne

Symbolica is an AI research lab pioneering the application of category theory to enable logical reasoning in machines. We’re a well-resourced, nimble team of experts on a mission to bridge the gap between theoretical mathematics and cutting-edge technologies, creating symbolic reasoning models that think like humans – precise, logical, and interpretable. We’re building AI that understands the structures of thought, not just patterns in data.

Our approach combines rigorous research with fast-paced, results-driven execution. We’re reimagining the foundations of intelligence while developing product-focused ML models in a tight feedback loop, where research fuels application.

Founded in 2022, we’ve raised over $30M from leading Silicon Valley investors to push the boundaries of applying formal mathematics and logic to machine learning.

Our vision is to create AI systems that transform industries, empowering machines to solve humanity’s most complex challenges with precision and insight.

You’ll join the founding team as our Sourcing Recruiter, taking full ownership of hiring deeply specialised technical talent in the AI space – from ML Engineers to Applied Researchers and beyond. This is a rare chance to directly shape the trajectory of the company by helping us hire the people who will build Symbolica’s core technology and future.

You’ll partner with the Talent Lead to design and run strategic searches that go far beyond traditional sourcing playbooks. You’ll spend most of your time sourcing exceptional passive talent, and you’ll also run full-cycle processes to help us move fast during high-growth periods.

This is a 5 days/week onsite role based in our London office (66 City Rd).
