Talent Acquisition Specialist

FirstPrinciples

8d • Remote

About The Position

FirstPrinciples is a research company building AI for scientific discovery. It began with Theo, the AI Physicist, and has since grown into a product-focused company with two additional systems including Theo Conjecture, built for automated conjecturing, and Theo Collaborator, an adaptive environment for doing complex research with AI.
We're a fast-growing, remote-first team of builders, researchers, engineers, and thinkers working across Canada, the US, the UK, and expanding globally. What brings us together is a shared curiosity about how the universe works, and a belief that we can build systems that help us explore it more effectively.
We spend our time working on questions that don't have clear answers, like how to design AI that can reason through scientific problems, and how the scientific process as a whole might evolve. This is work that sits somewhere between creativity and rigorous thinking, and often requires comfort with ambiguity and iteration. If you're someone who enjoys tackling big, abstract problems and exploring ideas that don't yet have a defined path forward, you'll likely find the work here interesting.
Why This Role Exists:
We're building something ambitious, and we're growing quickly. Today, we're a team of just over 35 people. By the end of the year, we'll surpass 50, and our plan is to double in size year over year as we scale our impact.
Every hire we make shapes the future of FirstPrinciples. That's why we're looking for someone who sees recruiting as more than filling roles; someone who is passionate about identifying exceptional people, building meaningful relationships, and helping assemble a team capable of solving some of the world's hardest scientific and engineering problems.
In this role, you'll work closely with the Director of Talent and have a direct hand in building the company. You'll partner closely with leaders across the organization, influence hiring strategy, and help attract the engineers, researchers, and operators who will define our next chapter of growth. If you're energized by high standards, meaningful ownership, and the opportunity to build an extraordinary team, we'd love to meet you.
