It combines information from multiple systems into a consolidated view, enabling IT teams to identify issues, analyze trends, and take action.\n\nIts underlying platform ingests continuously changing data, normalizes it, and maintains relationships between employees, departments, devices, and organizational structures. Role-based access controls govern how that information is used. The engineering challenge is to make high-volume data flows reliable and efficient while providing low-latency access to current information.\n\nAbout the Role:\n\nAs a Senior Data Engineer, you will build the streaming pipelines and distributed services that support this platform. This is a hands-on role centered on Java, Kafka, and Apache Flink. You will work from product requirements and architectural direction while owning complex implementation decisions, identifying risks early, and delivering production-ready components with minimal supervision.\n\nYou will join a small team developing the product and work with architecture, product, and DevOps colleagues. Early work includes understanding existing schemas and data sources, planning how data enters the platform, defining transformations and aggregations, and implementing, testing, and deploying those flows. The role involves substantial work on throughput, latency, persistence, reliability, and the operational behavior of systems processing data at scale.\n\nKey Responsibilities:\n\nBuild and maintain production Java services and high-throughput data-processing components.\n\nDesign, implement, and optimize Kafka and Apache Flink pipelines that combine data from multiple sources.\n\nPlan and implement data flows, including ingestion, normalization, calculation, aggregation, and persistence.\n\nDevelop the data model and services for employees, departments, devices, organizational relationships, and role-based access control.\n\nBuild service interfaces and data contracts using technologies such as gRPC and Protobuf.\n\nDesign persistence and data-access patterns across relational, analytical, and in-memory systems, including PostgreSQL, ClickHouse, and Redis where appropriate.\n\nOptimize schemas, queries, indexes, partitioning, and ingestion for large datasets.\n\nDiagnose bottlenecks and production incidents across streaming pipelines, services, and databases.\n\nImprove scalability, reliability, observability, throughput, latency, and operational cost.\n\nUse AI-assisted development tools while independently reviewing their output for correctness, security, and maintainability.\n\nRequired Competence and Skills:\n\nTypically 10+ years of experience building and maintaining production systems, including substantial hands-on work with distributed, high-throughput data platforms.\n\nTypically 5+ years of professional Java experience, with a strong grasp of concurrency, memory management, and JVM performance tuning.\n\nTypically 3+ years of production Kafka experience, including partitioning, consumer groups, schemas, delivery guarantees, fault tolerance, and throughput tuning.\n\nTypically 2+ years of production Apache Flink experience, including stateful processing, windowing, checkpointing, backpressure, fault recovery, and pipeline optimization.\n\nExperience building and operating systems that process millions of events per minute, with direct ownership of scaling or production performance decisions.\n\nStrong data-modeling and database optimization skills, including work with time-series data, high-volume ingestion, analytical workloads, and PostgreSQL or another relational database.\n\nExperience with Protobuf, schema evolution, and compatibility in distributed systems; familiarity with gRPC and service-to-service communication.\n\nHands-on experience monitoring, troubleshooting, and improving distributed production workloads, including incident resolution and resource management.\n\nPractical use of AI-assisted or agentic coding tools, paired with critical review of generated code before production use.\n\nAbility to own complex components independently, assess technical tradeoffs, and deliver maintainable solutions.\n\nNice to Have:\n\nExperience with ClickHouse or a comparable large-scale analytical database.\n\nPractical familiarity with CI/CD, Docker, Kubernetes, and production observability.\n\nExperience with TypeScript and React, including backend services or user-facing applications.\n\nExperience unifying data from multiple sources in Kafka-based pipelines.\n\nExperience with real-time analytics, anomaly detection, or complex event processing.\n\nExperience integrating AI or LLM-based capabilities, agentic workflows, or tool-based automation into production systems.\n\nWhy Us:\n\nWe provide 20 days of vacation leave per calendar year (plus official national holidays of a country you are based in).\n\nWe provide full accounting and legal support in all countries we operate.\n\nWe utilize a fully remote work model with a powerful workstation and co-working space in case you need it.","description_format":"text","description_chars":5352,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Ukraine","iso":"UA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-29T12:21:41Z"}],"visa":[],"liveness":{"score":76,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.844,"p_room":0.9,"age_days":10,"expected_fill_days":29,"reasons":["seen:10","velocity","win:mid"],"computed_at":"2026-11-01T06:10:25Z"},"pay":null,"html_url":"https://alion.io/job/adaptiq-senior-data-engineer-warsaw","json_url":"https://alion.io/job/adaptiq-senior-data-engineer-warsaw.json","meta":{"generated_at":"2026-11-01T07:12:59Z","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":11248,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-02T00:00:00Z"}},"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":4485822},"rest":"https://alion.io/mcp/rest/get_company?id=4485822"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fadaptiq-senior-data-engineer-warsaw"},{"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%2Fadaptiq-senior-data-engineer-warsaw"},{"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%2Fadaptiq-senior-data-engineer-warsaw"},{"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/adaptiq-senior-data-engineer-warsaw\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fadaptiq-senior-data-engineer-warsaw"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3454396}},{"tool":"search_jobs","arguments":{"company":"adaptiq.co","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3454396},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people);
