We didn't pivot to innovation; it's how we've always operated. What that means for the people who work here is real: genuinely complex problems to solve, the technology and resources to tackle them properly, and the kind of scope that's rare in established businesses.\nThe bar is high - bring a curious and forward-thinking mindset and we'll give you the platform to define what comes next.\nJoin us at IG - the future gets built here.\nYour Team:\nCompensation details will be shared by the recruiter during the first interview.\nIG’s Data function is a central capability serving both central and divisional business lines across the entire IG estate. The Data Engineering team is responsible for the platforms that underpin analytics, reporting, compliance, and client-facing data products, and that will increasingly power AI and machine-learning use cases across the firm.\nThe current data landscape reflects IG’s growth: a combination of GCP-native capabilities, on-premises systems, and a legacy AWS data platform. The strategic direction - endorsed by the CDO and Executive - is clear: consolidate onto GCP, raise the bar on data quality, and enable self-service access to trusted data for teams across the business.\nYour role in the Team’s Success:\nAs a Senior Data Engineer, you will design, build, and operate the data pipelines and platform capabilities that power IG’s analytics, compliance, and AI ambitions. Working within a squad led by the Data Engineering Team Lead, you will be a key technical contributor to IG’s GCP consolidation programme - tackling complex ingestion, transformation, and reliability challenges with a high standard of craft. You will also play a meaningful role in raising the bar for the wider team: mentoring junior engineers, championing data quality, and helping to define how the squad builds and operates at scale. \nWhat you’ll do:\nDesign and build robust batch and real-time data pipelines on GCP, including Kafka-based event streams, BigQuery transformations, and Airflow-orchestrated workflows, as part of the GCP consolidation and Medallion architecture build-out \nOwn data quality within your delivery area: define and implement data contracts, quality checks, and observability instrumentation so that pipeline health is visible and SLAs are met \nDevelop and maintain in-house connectors and third-party native integrations that form part of IG’s ingestion estate, ensuring resilience, monitoring, and long-term maintainability \nContribute to engineering standards and best practices across the squad - including code review, dbt modelling patterns, CI/CD pipeline hygiene, and change control for shared datasets \nSupport feature engineering and model data pipelines for Data Science, and help lay the foundations for AI-ready data - including lineage, reproducibility, and freshness guarantees for ML workloads \nWhat You'll Need:\nProven hands-on experience building and operating production-grade data pipelines on GCP - including BigQuery, Cloud Composer/Airflow, GCS, and Cloud Run - with strong SQL and Python skills \nSolid experience with Apache Kafka or equivalent streaming technologies, including designing event-driven ingestion patterns and troubleshooting real-time data flows under operational conditions \nFamiliarity with modern transformation tooling, particularly dbt, and an appreciation of Medallion (Bronze/Silver/Gold) architecture patterns and how they support self-service analytics \nA quality-first mindset: experience implementing data contracts, lineage tracking, observability tooling, and pipeline SLO monitoring in a production environment \nComfortable working in a regulated financial services environment, with an understanding of data governance requirements (lineage, access control, audit trails) and the discipline to operate within change control processes \n\nThe perks:\nCompetitive salary & benefits plan \nLife Insurance\nMyBenefit Platform\nMedical Insurance with Medicover\n1 additional day off to celebrate your Birthday \n2 additional days off a year for voluntary work \nShare Plans for Employees \nFree lunch at the office (ones per week)\nEmployee Assistance Program \nWe work in hybrid working model \nNumber of openings\n1","description_format":"text","description_chars":4443,"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":["Health insurance","Hybrid work","Life insurance"],"hiring_locations":[{"name":"Poland","iso":"PL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Online Brokerage & Trading Platforms","Forex & CFD Brokers"],"lifecycle":[{"event":"open","at":"2026-10-08T23:55:15Z"}],"visa":[],"liveness":{"score":60,"band":"ok","label":"Likely open","p_open":1,"p_active":0.795,"p_room":0.75,"age_days":17,"expected_fill_days":22,"reasons":["conf:4","velocity","win:late"],"computed_at":"2026-10-12T06:55:09Z"},"pay":null,"html_url":"https://alion.io/job/ig-senior-data-engineer","json_url":"https://alion.io/job/ig-senior-data-engineer.json","meta":{"generated_at":"2026-10-12T09:04:53Z","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":13594,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-13T00:00:00Z"}},"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":38407},"rest":"https://alion.io/mcp/rest/get_company?id=38407"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fig-senior-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%2Fig-senior-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%2Fig-senior-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/ig-senior-data-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fig-senior-data-engineer"}]}
