Join Sport Alliance and help build the data platform behind Magicline and Finion, serving thousands of gyms and 10M+ members. You'll tackle real engineering challenges, from high-volume data modeling and cost-efficient warehousing to freshness trade-offs and financial data that has to be exactly right.

We're building an AI-first data team. We use cutting-edge LLMs and internal tools to work faster, and we expect you to use and improve them. The platform you build powers our AI and analytics, making clean, reliable, well-modeled data essential.

Whether you're an experienced engineer ready to own the platform or a strong mid-level engineer eager to grow into the role, we'd love to hear from you.

Your position in our team

- Build and optimize cloud-native data pipelines on AWS โ€” ETL/ELT and the infrastructure underneath (Aurora, Redshift, dbt, Spark/EMR, Airflow, CDC) โ€” using AI tooling as a standard part of the workflow.

- Design and evolve the data models that power analytics, operational use cases, and AI/ML across thousands of studios.

- Help raise the bar on data reliability โ€” embed governance, testing, and lineage so both people and AI systems can trust the numbers by default.

- Partner with product, and other engineering teams to turn ambiguous business problems into robust data solutions.

- Evaluate and evolve new approaches with us โ€” data mesh patterns, and emerging AI tooling โ€” and help decide what genuinely earns a place in our stack.

- Grow into our financial and regulatory reporting workstream (Finion Capital), where correctness and auditability matter most.

Your profile

-
3+ years in data engineering with a focus on data warehousing โ€” and the appetite to take on more ownership than you've held so far.

- Strong SQL and Python for data work.

- Working with AI tools feels natural to you โ€” and, just as important, the judgment to review and validate what they produce. You treat AI output as a draft to verify, not an answer to trust, especially where correctness is non-negotiable.

- A solid grasp of data architecture and modeling principles (dimensional modeling, slowly-changing dimensions, incremental patterns) โ€” or the drive to deepen it fast.

- Hands-on experience with dbt on a cloud warehouse โ€” this is where you'll live day to day.

- Working knowledge of relational and some exposure to non-relational Databases (DynamoDB, MongoDB).

- A track record of debugging tricky data issues and shipping durable fixes.

- Excellent written and verbal English.

Nice to have

- AWS experience (Redshift, EMR, Glue, S3, IAM); experience with GCP or Azure is also welcome.

- Streaming/CDC technologies (Kafka, Kinesis, Debezium) or data mesh.

- Experience building data pipelines for ML or AI systems.

- Exposure to financial, payments, or regulated reporting data.

- German (helpful for some stakeholder work, but not required).

Your salary

- We offer a salary range of PLN 24,000 โ€“ PLN 28,000 gross per month (UoP).

- Final compensation will be based on experience, skills, and overall fit for the role

Your benefits with us

-
Benefits package โ€“ private medical care and a sports card to support your health and well-being

-
