Senior Quantitative Researcher | High-Frequency | Crypto Options

As a Senior Quantitative Researcher at BlockTech, you own a research agenda end-to-end, from hypothesis and dataset construction through feature engineering, model training, backtesting, live deployment, monitoring, and iteration. You work shoulder-to-shoulder with fellow researchers, traders, and analysts on an algorithmic trading floor, shaping how the firm prices and trades crypto derivatives and spot markets 24/7.

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 research, backtesting, and trading infrastructure together with engineers to move good ideas into production quickly and safely
• Monitor live performance of models in production, diagnose decay, and iterate 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

• 4+ years of hands-on quantitative research and/or applied ML experience, with a track record of models you have taken into production trading live
• A strong academic foundation in a quantitative discipline such as mathematics, physics, statistics, computer science, or ML/AI
• Fluency in Python and the modern ML stack, including PyTorch and/or TensorFlow, scikit-learn, NumPy, and pandas
• A deep, intuitive grasp of overfitting, generalisation, validation design, and feature engineering. You can explain why and how a model works, not just that it does
• The judgement to prioritise research bets independently and the communication skills to align researchers, engineers, and traders
• Strong software engineering instincts: production-grade code that others can read, test, and run
• Clear written and verbal English

Nice to have

• A live-trading track record, ideally in crypto derivatives or a similar domain
• Experience mentoring or leading other researchers
• Familiarity with market microstructure and derivatives pricing

What we offer

• Real ownership and a direct line to live PnL, with research, engineering, and trading located a few metres apart for the shortest feedback loops
• Competitive base salary plus a very attractive performance-based bonus tied to individual and company results
• For strong performers, the opportunity to buy into the trading fund
• A floor of strong peers and minimal bureaucracy between a good idea and production
• Annual learning and development budget and an in-house training program
• Pension plan, company laptop, and reimbursement of home internet costs
• Gym membership reimbursement and sports during working hours, including kickboxing, CrossFit, fitness, and soccer
• Daily breakfast and warm lunch, with snacks and drinks throughout the day
• Regular socials: weekly Friday drinks, monthly outings, quarterly sports competitions, and bi-annual trips abroad
• For internationals: an all-in relocation package and Dutch classes
