Lead Quantitative Developer

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 infrastructure and research teams through influence, not hierarchy - Accelerating the research cycle using in-house AI development tools — agentic coding assistants, end-to-end AI-driven workflows - Independently building and shipping strategy improvements where engineering quality has direct trading impact - What we're looking for     What we're looking for: - Strong mathematical and algorithmic thinking; solid grasp of statistics and probability - Ability to write production-quality C++ and Python 3 - Experience delegating technical work — not just assigning tasks, but framing problems so others can own them - Track record of growing junior and mid-level engineers - Deep systems understanding: ability to navigate the full stack from model training and simulation through to production — and reason about how a change at one layer affects others - Willingness to dive deep into market microstructure and strategy details - Experience with or strong interest in ML/AI tooling in research workflows     What we offer: - A dynamic and international environment within a fast-growing tech company - Salary at the upper end of the market, along with significant bonuses twice a year - Freedom to shape internal culture and create meaningful employee experiences, team-building activities - Health insurance, reimbursement of sports expenses; coverage for language courses - A supportive, experienced team that values collaboration — and where your impact will be visible every day If you're ready to lead at the intersection of engineering excellence and people growth — we'd love to talk!
