About the project

Join Sii and work with one of Europe’s leading fintech scale-ups.

We are currently looking for a Data Engineer to join Sii and contribute to a long-term project delivered for a Copenhagen-based fintech that’s redefining how businesses manage company spending, empowering over 40,000 organizations across Europe with smart cards and real-time financial insights. In this role, you’ll operate at the intersection of data and product engineering, building reliable, low-latency data pipelines that directly power customer-facing features in a modern, event-driven architecture.

Your responsibilities

• Building and maintaining product-serving data pipelines on AWS that feed the customer-facing serving layer — working to product backend reliability and latency standards, not analytical pipeline standards
• Contributing to the event infrastructure and ingestion pipelines that underpin real-time and near-real-time data serving
• Supporting the Kafka migration and data contract work needed to make the serving layer reliable at scale
• Working closely with backend and product engineering teams — this role sits at the data/product boundary, not inside the analytics function
• Owning pipeline reliability and monitoring for the serving layer, flagging and resolving issues with the urgency appropriate to customer-facing systems

Our requirements

• At least 5 years of experience as a Data Engineer in cloud-based environments
• Proven expertise with AWS-native data infrastructure (S3, Glue, Lambda, Step Functions)
• Strong Python engineering skills
• Experience in building low-latency, reliable data serving pipelines with SLOs and monitoring appropriate to customer-facing products
• Familiarity with streaming or event-driven data infrastructure (Kafka or similar) and understanding of the operational demands of real-time or near-real-time data flows
• Knowledge of event schemas and data contracts, and understanding of the downstream consequences of schema changes on consuming services
• Familiarity with fintech or regulated data environments, particularly payments, financial operations or compliance data
• Fluent English, both written and spoken
• Residing in Poland required
