Senior Quantitative Researcher | High-Frequency | Crypto Options

About BlockTech

BlockTech is an algorithmic trading firm operating at the frontier of global crypto derivatives and spot markets. We trade 24/7 across some of the fastest-moving, most data-rich venues in finance.

Crypto remains one of the few markets where a researcher can still meaningfully move the edge: abundant data, novel microstructure, and the shortest possible loop between a research idea and live PnL. We're looking for an experienced Quantitative Researcher to take ownership of that edge and push it further.

The role

This is a senior, hands-on research seat on our trading floor. You'll own a research agenda end-to-end from hypothesis, dataset construction, feature engineering, model training, backtesting, live deployment, monitoring, and iteration. You'll be trusted to set its direction.

You'll work shoulder-to-shoulder with fellow researchers, traders and analysts, shape how we price and trade, and help raise the bar for research across the floor, including mentoring less experienced researchers and influencing the tools and standards the team relies on.

You will:

Own price-prediction, signal, execution, and anomaly-detection models across crypto derivatives and spot markets from idea to live PnL

Shape our research, backtesting, and trading infrastructure together with engineers, so good ideas reach production quickly and safely

Own models in production: monitor live performance, 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 we're looking for

4+ years of hands-on quantitative research and/or applied ML experience, with a track record of models you've taken into production trading live

A strong academic foundation in a quantitative discipline (mathematics, physics, statistics, computer science, ML/AI, or similar)

Fluency in Python and the modern ML stack (PyTorch and/or TensorFlow, scikit-learn, NumPy, 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

Strong pluses:

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's in it for you?

Real ownership and a direct line to live PnL. Research, engineering, and trading happen a few metres apart, with the shortest feedback loops in the industry.

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 & 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 (kickboxing, CrossFit, fitness, soccer)

Daily breakfast and warm lunch, with snacks and drinks throughout the day

Regular socials: weekly Friday drinks, monthly outings, quarterly sports competitions, bi-annual trips abroad

For internationals: an all-in relocation package and Dutch classes
