The platform serves over 30 million monthly users and operates across 18 countries, making it one of the largest and most trusted digital marketplaces for vehicles in Europe.\nAbout the role\nWe are looking for a Data / Analytics Engineer to support the client team. The role sits close to the data analysts and business stakeholders, with a primary focus on maintaining and extending the data pipelines and data models that power analytics and reporting. The core stack includes SQL, Airflow, Athena, AWS Data Lake, and AI-assisted engineering tools such as Codex.\nThe client is currently migrating away from DBT and Snowflake to the clients data platform. The destination cloud and data platform already exists and is operational, and the migration itself will be handled by a different team - so this is not an infrastructure or platform engineering role. Instead, we need an engineer who can understand analytics use cases, translate business requirements into robust data solutions, and work independently to get those solutions into production. Beyond the technical skills, we are looking for someone with a strong sense of ownership and engineering judgment: a person who does not simply execute a ticket or accept a blocker at face value, but actively clarifies unclear requirements, investigates problems, proposes alternatives when the obvious approach does not work, and involves the right people when decisions are needed.\nResponsibilities:\nMaintain, troubleshoot, and improve existing data pipelines, and build new pipelines and datasets based on analytics and business requirements.\nDesign and maintain analytical data models, including fact and dimension models.\nIngest and integrate data from different source systems into the AWS Data Lake.\nBuild, deploy, validate, monitor, and, when necessary, backfill data pipelines.\nPartner with data analysts to understand their requirements and provide reliable, easy-to-use datasets.\nClarify requirements with business stakeholders rather than implementing ambiguous requests as-is.\nEnsure data quality through appropriate validation and testing, investigating data and pipeline issues and taking ownership of finding pragmatic solutions end to end.\nUse AI-assisted development tooling effectively while critically reviewing and validating generated solutions.\nRequirements:\nHands-on data engineering experience building and operating production data pipelines, ideally within analytics-driven environments.\nStrong SQL skills.\nExperience with data modeling for analytics, including fact and dimension tables.\nExperience with workflow orchestration, preferably Airflow.\nExperience working with AWS-based data environments, particularly Athena and AWS Data Lake.\nExperience with data validation, testing, and troubleshooting.\nStrong sense of ownership and engineering judgment: comfortable working with incomplete requirements, proactively seeking context, challenging assumptions when appropriate, and looking for practical solutions rather than stopping at the first blocker.\nExcellent verbal and written English skills, with clear communication across data analysts, engineers, and business stakeholders.\nNice to have\nExperience with data mesh architectures or working in a data mesh environment.\nExperience with marketplace, web/app, or digital analytics data.\nExperience with DBT and/or Snowflake.\nFamiliarity with AI-assisted engineering tools such as Codex\nWe offer*:\nFlexible working format - remote, office-based or flexible\nA competitive salary and good compensation package\nPersonalized career growth\nProfessional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)\nActive tech communities with regular knowledge sharing\nEducation reimbursement\nMemorable anniversary presents\nCorporate events and team buildings\nOther location-specific benefits\n*not applicable for freelancers","description_format":"text","description_chars":4080,"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":[{"language":"English","level":"All levels","optional":false}]},"benefits":["Flexible schedule","Professional development"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["IT Consulting & Digital Transformation","IT Outsourcing & Dedicated Teams","Custom Software Development","AI Consulting & Integration"],"lifecycle":[{"event":"open","at":"2026-10-03T12:09:54Z"}],"visa":[],"liveness":{"score":100,"band":"hot","label":"Hiring now","p_open":1,"p_active":1,"p_room":1,"age_days":10,"expected_fill_days":47,"reasons":["conf:0","wave","urgency","velocity","win:early","comp:brand"],"computed_at":"2026-10-06T05:45:30Z"},"pay":null,"html_url":"https://alion.io/job/n-ix-seniorlead-data-engineer-3","json_url":"https://alion.io/job/n-ix-seniorlead-data-engineer-3.json","meta":{"generated_at":"2026-10-06T22:40:13Z","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","counted_by":"address","units_charged":1,"used_today":3248,"day_limit":5000,"remaining_today":1752,"minute_limit":60,"resets_at":"2026-10-07T00:00:00Z"}},"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":13248},"rest":"https://alion.io/mcp/rest/get_company?id=13248"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fn-ix-seniorlead-data-engineer-3"},{"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%2Fn-ix-seniorlead-data-engineer-3"},{"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%2Fn-ix-seniorlead-data-engineer-3"},{"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/n-ix-seniorlead-data-engineer-3\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fn-ix-seniorlead-data-engineer-3"}]}
