Sourcing Recruiter (AI & ML Talent)

About Us

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.

While others focus on scaling data-hungry neural networks, 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 very foundations of intelligence while simultaneously developing product-focused machine learning models in a tight feedback loop, where research fuels application.

Founded in 2022, we’ve raised over $30M from leading Silicon Valley investors, including Khosla Ventures, General Catalyst, Abstract Ventures, and Day One Ventures, 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. Join us to redefine the future of AI by turning groundbreaking ideas into reality.

About The Role

You’ll join the founding team as our first 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, but in certain phases, you’ll also run full-cycle processes to help us move fast. We’re looking for someone who lives and breathes sourcing, thrives in ambiguity and automation, and brings both creativity and precision to every search.

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

Your Focus

• Own end-to-end sourcing strategy for highly specialised AI and technical roles
• Build and nurture long-term pipelines of world-class researchers, engineers, and hybrid profiles
• Design and implement sourcing ops, tools, AI automation, and workflows from the ground up in a zero-to-one environment
• Identify and engage talent across unconventional channels and niche communities
• Use advanced sourcing techniques and automation to surface hard-to-find candidates
