You would be the anchor hire of the data engineering team: the technical authority whose design decisions every other engineer builds on. You'd work directly with the Head of Data Engineering and the Head of ML, with the InPost executive team backing the build. This is an individual-contributor role with organisation-wide scope. Your influence comes from your technical credibility, not your headcount. Our word is extreme ownership.\n Your role:\nDesign, build, and operate batch and streaming data pipelines on the lakehouse (Databricks / Spark) that ingest, validate, and model data for credit origination, underwriting, and portfolio reporting\nBuild and maintain the feature store that BNPL Origination and MCA Underwriting consume, guaranteeing point-in-time correctness, freshness SLAs, and reproducibility for every served feature\nBuild and operate AI-first / agentic processes for the team's pipelines - designing the agent loop (context, tools, evals, guardrails) so agentic delivery is reliable, observable, and cost-controlled\nModel financial and behavioural data into governed, documented datasets with clear ownership, lineage, and access controls aligned to GDPR and internal data governance\nEmbed data-quality and observability as first-class deliverables: freshness, completeness, distribution, and schema-drift checks with alerting\nMaintain post-production accountability for owned pipelines - monitoring, incident response, root-cause analysis, and iterative improvement\nWork with a feature store with point-in-time-correct data, using Databricks and Spark, with tracing for pipeline observability.\nYou will own agentic harnesses and loop- and graph-based agent workflows around the feature store. You design the agent loop (context, tools, state, evals, guardrails) for feature creation, freshness, and data-quality monitoring.\n 5+ years in data engineering (pipelines, modelling)\n3+ years with Spark / Databricks or an equivalent lakehouse\n5+ years using SQL, data modelling, and Python for data engineering\n2+ years of advanced agentic coding tools and loop engineering - context/tool design, evals, guardrails, iteration\nBatch and streaming pipeline design on a lakehouse architecture\nDimensional and event-based data modelling for analytical and ML consumption\nSQL performance tuning and partitioning on large tables\nPython and Spark; orchestration (e.g. Airflow / Workflows)\nQuriosity to do Advanced agentic tooling and loop and graph engineering.\nEval and guardrail design.\nSolid LLM working knowledge.\nData lineage, cataloguing, and governance thinking (GDPR-aware)\nEnglish proficiency at B2 or above\nUniversity degree in Computer Science, Data Engineering, Mathematics, or a related field\nNice to have:\n1+ years with feature store / ML data serving\n1+ years with payments / fintech or lending data\n1+ years with streaming (Kafka / Structured Streaming)\nPayment / lending domain data (authorisation, ledger, repayment, delinquency)\nCredit-risk feature design and scoring-pipeline data\nReal-time streaming and CDC patterns\ndbt or equivalent transformation frameworks\nCost and performance optimisation on Databricks\n Opportunity to work in a diverse, international, and cross-functional environment, along with leading experts. \nYou work and learn from a senior leader and their leadership team, expanding your experience and exposure in the e-commerce and logistics industries. \n InPost is a growing company that offers its people an increasing number of opportunities in several locations in Europe. \nFulfilling careers with a range of benefits for people and investing in providing training opportunities for their development. \nYou will feel a part of the InPost community that makes an impact on sustainability, convenient deliveries, and the circular economy every day. \nExcellent working environment and flexible hours\n We offer B2B type of contract","description_format":"text","description_chars":3951,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"Upper-Intermediate (B2)","optional":false}]},"benefits":[],"hiring_locations":[{"name":"Poland","iso":"PL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Financial Services","Delivery","Logistics","Courier Services"],"lifecycle":[{"event":"open","at":"2026-10-14T17:29:50Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":28,"reasons":["conf:0","win:early","comp:brand"],"computed_at":"2026-10-14T21:01:37Z"},"pay":null,"html_url":"https://alion.io/job/inpost-senior-data-engineer-fintech-engineering-mfn","json_url":"https://alion.io/job/inpost-senior-data-engineer-fintech-engineering-mfn.json","meta":{"generated_at":"2026-10-14T21:01:37Z","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":28074,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-15T00:00:00Z"}},"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":3343},"rest":"https://alion.io/mcp/rest/get_company?id=3343"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Finpost-senior-data-engineer-fintech-engineering-mfn"},{"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%2Finpost-senior-data-engineer-fintech-engineering-mfn"},{"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%2Finpost-senior-data-engineer-fintech-engineering-mfn"},{"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/inpost-senior-data-engineer-fintech-engineering-mfn\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Finpost-senior-data-engineer-fintech-engineering-mfn"}]}
