BlockTech is hiring a Quantitative Trader to join its Delta One trading floor in Singapore.

You'll own positions and PnL end-to-end, from reading live market flow to tuning and stepping into our automated systems.

In this role, your decisions directly drive how we trade across venues.

About BlockTech

BlockTech is an algorithmic trading firm headquartered in Amsterdam, with a second office in Singapore. We specialize in market making and trade cryptocurrency derivatives and spot markets globally, using our own capital. We're growing fast and expanding into new markets.

Delta One is where we trade linear products: perpetual futures, futures, and spot. You'll sit shoulder to shoulder with Quantitative Researchers, Quantitative Developers, and Software Engineers.

What will you do?

You will own D1 positions and the PnL and risk that come with them. Beyond the day-to-day, you'll shape the next generation of execution logic and the trading tools the desk relies on.

You will:

Own the book. Manage and monitor D1 positions across multiple venues, along with the PnL and risk that come with them.

Read the market. Turn live market flow, liquidity conditions, and market events into concrete trading and execution decisions.

Run the systems. Tune and parameterize our automated and semi-automated systems, and know when to step in to manage risk or capture an opportunity.

Sharpen execution. Improve execution quality and market-making performance through data-driven analysis of strategy behavior.

Spec the desk's tools. Design the trading tools, dashboards, and analytics the desk uses to make decisions.

Shape the roadmap. Work with researchers, developers, and engineers to sharpen models, infrastructure, and execution logic, and drive new trading initiatives.

What we're looking for

You'll need:

3+ years as a Quantitative Trader and/or Quantitative Researcher in a professional trading environment, with demonstrated PnL responsibility on linear (D1) products across multiple venues.

Hands-on experience operating automated and semi-automated trading systems under live conditions: monitoring, tuning, and intervening when it matters.

Strong analytical instincts. You can take a messy dataset of fills and quotes and turn it into a concrete execution improvement.

A deep, intuitive grasp of market microstructure, and the ability to explain why a strategy works, not just that it does.

Proficiency in Python for analysis, tooling, and working with trading systems.

An ownership mindset. You're proactive, accountable, and comfortable making decisions with immediate financial impact.

Clear written and spoken English, and the ability to communicate with traders, researchers, and engineers.

Bonus points for:

Exposure to systematic HFT and MFT strategies, ideally in crypto D1 markets.

Pay, location, and relocation

Compensation: a competitive base salary plus a performance bonus based on individual and company results.

Trading fund: outstanding performance is rewarded with the opportunity to buy into the trading fund.

Location: On-site at our Singapore office, in the heart of the financial district (CBD)

Relocation: All-in relocation package for international hires.

What else is in it for you

Company laptop, home office budget, and transportation allowance

An extensive in-house training program and an annual learning and development budget

An environment that embraces AI, both to speed up your work and to advance our systems

Gym and sports event reimbursement, plus sports during working hours

Frequent outings and two trips abroad a year

Daily breakfast and warm lunch, plus snacks and drinks all day

How we work

We're a team of trading and tech enthusiasts with a flat hierarchy. Have an idea today, and it can ship tomorrow. The best idea wins, whoever it comes from.

This role comes with a high degree of autonomy. You'll own hard problems from concept to production and solve them your way. We promote reverse leadership, give everyone an equal playing field, and invest in personal and professional development.
