Job description

BlockTech is a fast-paced algorithmic trading firm facilitating global cryptocurrency derivatives and spot trading while expanding into new markets. As we continue to grow rapidly, we are looking for a Software Engineer to join our Core team amid our exciting scale-up phase!

The role

In this role, you will work on the systems that keep our trading operation accurate at every level, positions, PnL, instruments, hedging, and the data flowing between them. Across exchanges and asset classes, your work determines whether the numbers our traders and risk team rely on are correct.

Own the books. Maintain and evolve our position, trade, and PnL systems so they remain accurate across every venue we operate on.

Build the platform that supports trading. Design services that handle real-time exchange flow with the throughput and reliability on which our quoting and hedging depend.

Own the data flows. Operate the public and private data pipelines that bring market prices, account state, and trade events into our systems in real time.

Integrate new venues. Deliver exchange and prime-broker integrations end-to-end, protocol, account model, settlement, reconciliation, and surveillance.

Model the instrument universe. Own the systems that describe every tradable instrument we trade, lifecycle, expiry, margin, RFQs, fast-path quoting, where both correctness and latency matter.

Develop self-healing systems. Build the detection and repair flows that identify position discrepancies and correct them automatically.

Build hedging infrastructure. Design and refine the gamma and delta hedging systems that our trading strategies depend on.

Deliver reporting. Provide the data that internal stakeholders and regulators require, PnL breakdowns, trade surveillance, treasury accounting, and compliance.

What we're looking for

• 1+ years of commercial working experience as a Software Engineer. We are looking for an engineer with breadth: someone comfortable moving between a Rust service, a Python data pipeline, and a complex production issue, and choosing the right tool for each.
• Familiarity with Grafana & PostgreSQL
• A critical mind that follows things until completion
• The ability to confidently work on completely new components
• A high level of responsibility and ownership
• Good written and verbal communication skills in English

What's in it for you?

• A full-time position in a relaxed and modern office in Amsterdam
• Competitive compensation consisting of a base salary combined with a very attractive bonus plan based on individual and company performance
• Outstanding performance is rewarded with the opportunity to buy into the trading fund
• Pension plan, company laptop, and reimbursement of your internet costs at home

• The opportunity to work at the forefront of automated trading using state-of-the-art technology, in an environment that embraces AI to both accelerate productivity and advance our systems and models
• 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. Additionally, snacks and drinks are provided throughout the day
• For internationals: All-in relocation package and Dutch classes
