Quantitative Trading Citadel Jobs (NOW HIRING)

Career Reinvention Without Starting Over – This role is for research analysts who love the intellectual rigour of fundamental equity research but have grown frustrated with the grind: the long hours, the tedious manual processes, and the limited upward trajectory beyond portfolio management. We let you leverage everything you have built across your research career while shedding the parts that make the job unsustainable. You are not pivoting away from finance – you are redefining what finance work looks like in the AI era.

Skip the AI Adoption Lag – Most hedge funds are still years away from meaningfully integrating AI into their core investment workflows. If you believe AI will transform how research gets done and are tired of waiting for your firm to catch up, we put you at the frontier of that transformation today. You will not be experimenting on the side or lobbying for internal adoption – building and deploying AI-powered research workflows is the job.

Genuine Ownership and Direct Access to Decision-Makers – With a lean team and no layers of bureaucracy, individuals at all levels are trusted to drive decisions and outcomes – with scope meaningfully broader than at larger or more structured organisations. That same flatness extends to the client side: you are working on-site directly alongside heads of research and C-suite executives at some of the most sophisticated hedge funds in the world. That level of visibility is extremely difficult to access from a traditional analyst seat, and it compounds over time.

Ground-Floor Team With Real Momentum – We are building this forward-deployed analyst function from scratch and looking to scale from one or two people to five as quickly as possible. Joining now means you are not slotting into an established team with rigid processes – you are helping define the playbook for how AI adoption gets delivered to institutional investors.

Bootstrapped, Post-PMF, and Built to Last – We've reached $10M+ ARR with a lean team and no external funding – a strong signal of genuine product-market fit built on real revenue, not VC runway. There are no externally imposed milestones or investor pressure dictating the roadmap. For candidates who want to join at the most exciting inflection point – where the product has proven itself but the scaling is still ahead – this is a rare opportunity to have outsized impact and grow alongside the business as it enters its next phase.

R&D Culture Within a Commercial Business – The company operates like a hybrid between a SaaS startup and an R&D team – constantly evaluating new developments in AI and accommodating the roadmap accordingly. Engineers are not just building towards a fixed vision; they are actively contributing to how that vision evolves. The culture values curiosity, craft, and elegant solutions to genuinely hard problems.

Calibre of the Team – The engineering team brings experience from some of the most demanding institutions in finance and technology – Citadel, Goldman Sachs, Millennium, and D.E. Shaw. For candidates who care about the quality of the people they work alongside and who they can learn from, this is a meaningful signal.
