LeadQuantitativeDeveloper

We are Pinely, a high-frequency algorithmic trading firm based in Amsterdam. Our team specializes in developing robust and adaptive strategies applicable across a wide range of financial instruments and exchanges. We actively support the Olympiad movement, and many of our colleagues are prize-winning mathematicians, researchers and engineers. Researchers at Pinely benefit from working in a fast-paced HFT environment, where the impact of their ideas is quickly visible in production. The research teams are supported by a world-class infrastructure group that ensures smooth deployment and reliable experimentation at scale. Our flat organizational structure encourages autonomy, creativity, and direct ownership. We value an informal, idea-driven culture where innovation is celebrated and every contribution matters. **About the role: ** We're looking for a **Lead Quantitative Developer** to join one of our trading teams - someone who combines deep technical ownership with the ability to grow and lead people. The team is intentionally small by design - close mentorship, no bureaucracy. Great leadership here means staying in the trenches, not stepping away from them. We're building toward a research lab culture. That means: understanding **why** something works, not just making it work. Reducing vague problems to core uncertainties before writing code. Intellectual honesty - with yourself and in the code you review. And the courage to push back and own decisions when it matters. **What you'll do** * Owning and evolving the team's strategy codebase with direct P&L impact * Decomposing research and production problems into concrete, delegatable tasks with clear success criteria * Growing QDs on the team - understanding their strengths, motivations, and career goals; giving regular feedback that amplifies rather than just corrects * Prioritizing QD capacity across competing demands: research requests, production stability, infra timelines * Driving alignment with infrastructur
