What You’ll Do

This team ensures that data is reliable, accurate and available when it’s needed.

• Proficient in SQL, ETL processes and at least one programming language (Python, Scala or C++).
• Strong focus on automation, system resilience and continuous improvement.
• Passionate about data quality, observability and performance optimization.
• Structured and methodical in problem-solving, with strong debugging skills.
• Excellent communication skills and a collaborative, proactive mindset.

Nice to have

• Experience with Databricks, data observability platforms or distributed/cloud-based data systems.
• Familiarity with alerting and monitoring tools (e.g. Grafana, Prometheus, Airflow or similar).
• Exposure to financial data pipelines or low‑latency trading environments.

What You’ll Get

You’ll join a culture of collaboration and excellence, where you’ll be surrounded by curious thinkers and creative problem solvers. Driven by a passion for continuous improvement, you’ll thrive in a supportive, high‑performing environment alongside talented colleagues, working collectively to tackle some of the most complex problems in the financial markets.

• A performance‑based bonus structure unmatched anywhere in the industry.

• Training, mentorship and personal development opportunities.
• Daily breakfast, lunch and an in‑house barista.
• Gym membership plus weekly in‑house chair massages.
• Regular social events, including a company trip every two years.
• Guided relocation, a competitive relocation package and visa sponsorship where necessary.
