Your team

• A highly technical and innovative team leading automated trading in eCredit
• Focused on maximising automation and performance in order to drive eTrading revenues
• Operating in a highly agile manner, releasing to production multiple times per day
• The team is known for being collaborative and diverse, with a mandate to deliver meaningful change

Your expertise

• 8+ years of hands‑on data engineering in production environments, with strong, idiomatic Python used for reliable, well‑tested systems (not exploratory notebooks).
• Design and operation of large‑scale ETL/ELT pipelines, including orchestration (Airflow, Prefect, or similar) and reliability patterns such as retries, backfills, and exactly‑once semantics.
• Deep experience with Azure, including AKS, Helm, EventHub, observability tools (e.g. Log Analytics) and infrastructure‑as‑code (e.g. Terraform).
• Advanced experience operating Delta tables at scale, covering transaction semantics, schema evolution, partitioning, and compaction, alongside highly optimised analytical query execution using DuckDB or Apache Spark.
• Production‑grade relational database expertise, particularly PostgreSQL (query tuning, indexing, partitioning, replication, and schema design across OLTP and analytics).
• Strong KDB experience, covering key concepts such as tp/ctp/rdb/hdb and differences between real‑time vs historical queries and usage of gateways.
• Containerised data workloads using Docker and Kubernetes, with reproducible, environment‑agnostic deployment of data infrastructure.
• Analytical data modelling expertise, including dimensional models or data vaults, schema evolution, slowly changing dimensions, and downstream impact analysis.
• Strong experience managing and troubleshooting environments based on visualization and data analytics technologies such as JupyterHub, PowerBI, Streamlit and Marimo.
• Batch and streaming processing proficiency, including late data handling, watermarking, backfills, and explicit throughput vs latency trade‑offs.
• Production data reliability and observability mindset, covering lineage, data quality checks, SLAs, CI/CD for data pipelines, and close collaboration with quants, risk managers, and traders to deliver trustworthy data products.
• 2+ years of experience in Java, covering react‑based applications.
• Experience delivering business‑facing solutions enhanced by AI and using AI assisted development (including prompt driven workflows and MCP servers) to reduce context switching and accelerate reliable delivery.
• You’re curious to explore how AI can improve how we build, deliver, and optimise workflows. You do this with sound judgment – validating outputs and aligning with policies, risk standards, and ethical use.
