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.\nWe'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.\nWhether 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.\n\nYour position in our team\n\nBuild 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.\n\nDesign and evolve the data models that power analytics, operational use cases, and AI/ML across thousands of studios.\n\nHelp raise the bar on data reliability — embed governance, testing, and lineage so both people and AI systems can trust the numbers by default.\n\nPartner with product, and other engineering teams to turn ambiguous business problems into robust data solutions.\n\nEvaluate and evolve new approaches with us — data mesh patterns, and emerging AI tooling — and help decide what genuinely earns a place in our stack.\n\nGrow into our financial and regulatory reporting workstream (Finion Capital), where correctness and auditability matter most.\n\nYour profile\n\n3+ years in data engineering with a focus on data warehousing — and the appetite to take on more ownership than you've held so far.\n\nStrong SQL and Python for data work.\n\nWorking 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.\n\nA solid grasp of data architecture and modeling principles (dimensional modeling, slowly-changing dimensions, incremental patterns) — or the drive to deepen it fast.\n\nHands-on experience with dbt on a cloud warehouse — this is where you'll live day to day.\n\nWorking knowledge of relational and some exposure to non-relational Databases (DynamoDB, MongoDB).\n\nA track record of debugging tricky data issues and shipping durable fixes.\n\nExcellent written and verbal English.\n\nNice to have\n\nAWS experience (Redshift, EMR, Glue, S3, IAM); experience with GCP or Azure is also welcome.\n\nStreaming/CDC technologies (Kafka, Kinesis, Debezium) or data mesh.\n\nExperience building data pipelines for ML or AI systems.\n\nExposure to financial, payments, or regulated reporting data.\n\nGerman (helpful for some stakeholder work, but not required).\n\nYour Benefits With Us\n\nBenefits package – private medical care and a sports card to support your health and well-being\n\nAccess to Udemy Business – boost your skills with thousands of high-quality online courses\n\nFlexible work model – work fully remotely or combine it with on-site collaboration at our modern office in Warsaw\n\nFlexible Working Hours – adjust your schedule to fit your lifestyle\n\nUnique experience in the Fitness and SaaS industry – join a market-leading company in a dynamic, fast-growing industry\n\nInternational team – work alongside talented colleagues from around the world in a diverse and inclusive environment\n\nUnforgettable company events – take part in engaging team-building activities and memorable celebrations\n\nTech stack\nSQL\nPython\nDBT\nData Warehousing\nData modeling\nAI Tools","description_format":"text","description_chars":3676,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Company events","Flexible schedule"],"hiring_locations":[{"name":"Poland","iso":"PL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-08T23:50:21Z"}],"visa":[],"liveness":{"score":73,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.809,"p_room":0.9,"age_days":13,"expected_fill_days":28,"reasons":["seen:13","win:mid"],"computed_at":"2026-10-20T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/perfect-gym-ai-first-data-engineer","json_url":"https://alion.io/job/perfect-gym-ai-first-data-engineer.json","meta":{"generated_at":"2026-10-20T13:27:10Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":14914,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-21T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":173738},"rest":"https://alion.io/mcp/rest/get_company?id=173738"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fperfect-gym-ai-first-data-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fperfect-gym-ai-first-data-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fperfect-gym-ai-first-data-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/perfect-gym-ai-first-data-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fperfect-gym-ai-first-data-engineer"}]}
