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!
