Senior Quantitative Researcher | Mid-frequency | Crypto Options

BlockTech is hiring a Senior Quantitative Researcher to develop mid-frequency trading capabilities on the Amsterdam trading floor. You will own the research agenda end to end, from hypothesis and dataset construction through model training and backtesting to live deployment. You'll sit with traders, researchers, and analysts, and raise the bar for research across the floor.

What you'll do

• Own price-prediction, signal, execution, and anomaly-detection models across crypto derivatives and spot markets from idea to live PnL
• Shape the research, backtesting, and trading infrastructure together with engineers, so good ideas reach production quickly and safely
• Own models in production by monitoring live performance, diagnosing decay, and iterating on what you ship
• Set research direction alongside traders, deciding which trades are worth making and why
• Raise the research bar by mentoring colleagues, reviewing work, and setting standards for rigour

What you bring

• 3+ years of quantitative research experience at a hedge fund, trading firm, or similar, with mid-frequency models you have taken live
• A strong academic foundation in a quantitative discipline such as mathematics, physics, statistics, or computer science
• Fluency in Python and the modern ML stack, including PyTorch and/or TensorFlow, scikit-learn, NumPy, and pandas
• A deep grasp of overfitting, validation design, and feature engineering. You can explain why a model works, not just that it does
• Software engineering instincts: you write production-grade code that others can read, test, and run
• The judgment to prioritize your own research bets, and clear communication with traders and engineers

Nice to have

• A mid-frequency track record in crypto derivatives markets
• Experience mentoring or leading other researchers

What we offer

• A seat on a trading floor where research, engineering, and trading happen a few meters apart, guaranteeing short feedback loops, real ownership, and direct impact on live PnL
• Competitive compensation consisting of a base salary combined with a very attractive bonus plan based on individual and company performance, with the opportunity to buy into the trading fund for outstanding performance
• Pension plan and company laptop
• Reimbursement of internet costs at home
• An extensive in-house training program and an annual learning and development budget
• Gym membership reimbursement and the opportunity to engage in various sports during working hours, including kickboxing, CrossFit, fitness, and soccer
• Regular social events including weekly Friday drinks, monthly outings, quarterly sports competitions, and bi-annual trips abroad
• Daily breakfast and warm lunch, with snacks and drinks provided throughout the day
• For internationals: an all-in relocation package and Dutch classes
