As a Senior Data Engineer on the Financial Flows team, you will take full technical ownership of the end-to-end data pipelines, predictive models, and cloud infrastructure powering Kpler’s commodity finance analytics. You will lead the modernization of our data foundation, spearheading the migration of production services to AWS and re-architecting legacy calculation engines into clean, performant Python services. Operating at the crossroads of quantitative research and cloud infrastructure, your work will directly ensure that market participants receive real-time, mission-critical insights across global commodities markets.
Key Responsibilities
Design, build, and operate resilient batch and real-time streaming data ingestion pipelines connecting to external financial market data providers via APIs and WebSockets.
Lead the architectural migration of legacy backend infrastructure to modern cloud-native environments on AWS, establishing high standards for system reliability and scalability.
Drive the refactoring and rewrite of the CTA positioning indicator calculation blocks from PHP to Python, ensuring strict mathematical output parity, comprehensive test coverage, and optimized latency.
Ingest and model complex financial datasets—including futures pricing, open interest, and trading volumes—across time-series stores and search engines like QuestDB and Elasticsearch.
Implement automated data validation, proactive alerting, and system monitoring to ensure market data feeds remain accurate, continuous, and fault-tolerant.
Deploy, maintain, and scale containerized services across Docker and Kubernetes environments using automated CI/CD pipelines and GitOps workflows.
Partner closely with quantitative researchers, commodity analysts, and product managers to translate complex trading models into high-performance production pipelines.
Provide technical mentorship to peer engineers, raising team-wide engineering rigor through thoughtful code reviews, system design guidance, and architectural documentation.
Experience & Background
5+ years of professional experience building, operating, and scaling production-grade data pipelines and backend infrastructure.
Advanced expertise in Python, with a strong background refactoring and rewriting production-critical code for performance and testability.
Proven hands-on experience building and maintaining real-time or streaming API ingestion pipelines (REST, WebSockets) handling time-series datasets.
Solid production experience deploying and managing containerized applications on AWS using Docker, Kubernetes, and modern CI/CD practices.
Strong database fundamentals in SQL and experience working with distributed search or time-series databases (e.g., Elasticsearch, QuestDB, ClickHouse).
Deep experience establishing automated data quality frameworks, observability (monitoring/alerting), and root-cause troubleshooting for production systems.
Nice-to-havesDomain knowledge of financial market structures, futures contracts, open interest, and commodities trading symbology.
Experience integrating data from major financial market vendors (e.g., Bloomberg, LSEG, Enverus, Trading Technologies).
Familiarity with legacy PHP codebase migration or reading PHP algorithms to translate into Python.
Practical familiarity with GitOps frameworks and infrastructure-as-code tooling.
