AI-First Data Engineer

Join Perfect Gym a Sport Alliance Company and help build the data platform behind Magicline and Finion, serving thousands of gyms and 10M+ members. You'll tackle real engineering challenges in data engineering, using AI tooling and building cloud-native pipelines on AWS.

• Build and optimize cloud-native data pipelines on AWS — ETL/ELT and the infrastructure underneath (Aurora, Redshift, dbt, Spark/EMR, Airflow, CDC) — 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 — 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 — data mesh patterns, and emerging AI tooling — 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.

• 3+ years in data engineering with a focus on data warehousing — 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 — 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) — or the drive to deepen it fast.
• Hands-on experience with dbt on a cloud warehouse — 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.

• Benefits package – private medical care and a sports card
• Access to Udemy Business – boost your skills with thousands of high-quality online courses
• Flexible work model – work fully remotely or combine it with on-site collaboration at our modern office in Warsaw
• Flexible Working Hours – adjust your schedule to fit your lifestyle
• Unique experience in the Fitness and SaaS industry – join a market-leading company in a dynamic, fast-growing industry
• International team – work alongside talented colleagues from around the world in a diverse and inclusive environment
• Unforgettable company events – take part in engaging team-building activities and memorable celebrations
