We are looking for a Senior Data Engineer to design, build, and scale the data infrastructure that powers products and decision-making. This role is central to how data flows across the organization—from ingestion and processing to analytics and insights. You’ll work closely with developers, analysts, and trading teams to ensure data is reliable, accessible, and built for the future.

• Develop clear, well‑structured data models and maintain documentation to support analytics and self‑service.
• Collaborate with software developers, analysts, and trading teams to deliver reliable and scalable data solutions.
• Identify opportunities to improve performance, automate processes, and enhance data quality and reliability.

• Python: Strong expertise; C# experience is a plus.
• SQL: Comfortable with complex queries and query tuning on relational and analytical databases (e.g., PostgreSQL, ClickHouse).
• Containers: Experience building, running, and deploying containerised services in local and production environments.
• Cloud platforms: Experience with Azure and distributed systems.

Preferred Skills

• Kubernetes & Helm: Deploying and managing containerised applications at scale with reliability and fault tolerance.
• Kafka (Confluent): Familiarity with event‑driven architectures; experience with Flink or KSQL is a plus.
• Airflow: Experience configuring, maintaining, and optimising DAGs.
• Energy or commodity trading: Understanding the data challenges and workflows in this sector.
