Data Engineer

Data Engineer

Location: Poland (hybrid; 2–3 days/week onsite in our office space at Business Link Astoria, Google Maps)

Reports to: Data Team Lead

About the role

We’re looking for a pragmatic and hands-on Full Stack Data Engineer to take end-to-end ownership of our data platform. A key part of this role is data democratisation: bringing trusted data to everyone at Coople in a way that is easy to use, discoverable, and consistent. As a data-driven organisation, we want to evolve to an environment where data is truly available “everywhere” and is a default input into day-to-day and strategic decisions.

Our core stack includes Databricks (Data Lake) and Power BI (reporting). The next step is to evolve our data development environment and data stack into an AI-first setup: we want to use AI wherever it creates leverage (development, testing, documentation, data quality checks, incident response, and stakeholder enablement), and continuously optimize our stack and ways of working for faster, safer delivery.

To make data accessible, we also want to enable conversational access to data (a chat interface for metrics, definitions, and insights) so that non-technical stakeholders can reliably get answers fast, with clear context and trust signals. You will work closely with development teams and stakeholders in Warsaw (partly in person/hybrid) and you’ll often act as the “glue” between product engineering, business users, and clients in other locations too.

In this role you can expect a.o.

End-to-end data ownership

• Own the full data lifecycle: ingest data from source systems, build and maintain reliable pipelines into the Data Lake, and curate datasets that are trustworthy, traceable, and easy to use for analytics, product teams, and reporting.
• Deliver high-signal dashboards and reporting in Power BI, while partnering with stakeholders to refine requirements, standardise metric definitions, and improve discoverability and self-service through documentation, catalogs, and AI.

Data democratisation & decision enablement

• Make data easy to use for everyone at Coople by reducing friction to get answers and maintaining a clear single source of truth for key metrics, definitions, and ownership.
• Enable a “data in every decision” culture by embedding insights into planning and operations, and supporting and help shaping a chat-based interface that lets stakeholders query data in natural language with reliable, contextualised answers.

AI-first data engineering

• Evolve the data stack and development environment toward AI-optimised workflows, including prompting patterns, automation, and review practices.
• Use AI to improve data quality, testing, lineage documentation, and operational runbooks while continuously improving speed, reliability, and maintainability of the platform.

Collaboration & operational excellence

• Partner closely with Warsaw-based development teams to ensure robust data contracts, event definitions, and integrations...
