From powering car rental to creating smarter ways to move, we make travel smoother for millions worldwide. Our culture is built on curiosity, collaboration and craic where every idea counts and every journey matters. Ready to make an impact?\nLet’s go places together.\nThe Senior Data Engineer - Digital & Behavioural Telemetry owns the engineering and evolution of the digital behavioural and telemetry data that explains how customers interact with CarTrawlerproducts and partner experiences. Sitting within Data Engineering, the role combines behaviouraltelemetry,web-engine telemetry, Real User Monitoring (RUM) and conversion data with practical standards for instrumentation, event contracts and governed downstream use.\nThe role works closely with Product & Technology engineering teams to ensure new features, productsand journeys produce consistent, contextualiseddata enabling analytics. Working with Data Engineering to turn signals into reusable data products and certified metrics. The role provides senior technical ownership for the digital & behaviouraltelemetry domain, operatingwithin theData Engineeringplatform architecture. Workingwith product anddomain teams to convert trusted behaviouraldataand digital telemetry datainto governed analytical products.\nWhat you will do as a Senior Data Engineer:\nDigital & Behavioural Telemetry Data Engineering: Shapes the unified behavioural data models that connect customer actions, journey stages, product interactions and technical telemetry, enabling consistent analysis of how users move through digital experiences across partners, products and channels. Integrate web-engine telemetry, real user monitoring and related event data so that behavioural patterns, friction points and conversion opportunities can be understood reliably.\n\nInstrumentation, Tagging & Event Contracts: Partner with P&T engineering teams to define how product and web events are tagged, named, contextualised and versioned. Establish reusable event taxonomies, identifiers, metadata and testable contracts so new features and journeys produce reliable data. Evolve the digital behavioural data implementation, including development and debugging capability.\n\nConversion Performance & Digital Journey Data Products: Engineer and evolve governed data products that measure performance across key digital journeys and acquisition and revenue funnels. Provide the behavioural data foundations required to measure session and search activity, availability, funnel progression, booking conversion, ancillary and revenue outcomes, and agreed attribution measures.\n\nData Enablement & Analytics Enablement: Turn product, engineering and business data needs into reusable, governed data structures that can be consumed safely downstream. Contribute event definitions, technical context, lineage and KPI guidance to the central definitions repository, using documentation-as-code and Markdown for business and metric definitions.\n\nObservability Engineering: Connect behavioural and customer-journey data with real user monitoring and relevant operational telemetry so teams across CT can understand how technical performance influences customer experience, conversion and journey progression.\n\nQuality, Security & Lifecycle: Set and implement expectations for data quality at creation, automated testing, breaking-change controls, ownership, classification, access, privacy, retention and handling of sensitive data. Ensure critical telemetry and conversion data products are monitored, documented, discoverable and safe to evolve.\n\nPartner, Analyst & Product Enablement: Act as the senior technical SME for analysts, P&T teams and partner questions relating to telemetry, tagging and digital behavioural data. Maintain a digital measurement and data roadmap that identifies the data capability required to quantify behavioural friction, conversion performance, technical performance and website or product experience opportunities.\n\nWhat you’ll bring to the team:\n5-7+ years' experience in data engineering, digital analytics engineering, product telemetry or a related technical role, with evidence of senior ownership across production data products and cross-team delivery.\n\nStrong hands-on experience engineering digital behavioural or telemetry data in a production environment, using an event collection platform such as Snowplow, Adobe Experience Platform ,Google Analyticsor acomparable technology.\n\nPractical experience with event tracking and telemetry concepts such as schemas, enrichments, event contexts, processing pipelinesand warehouse data models, including local development, debuggingand testing approaches.\n\nAdvanced SQL and strong Python skills, with hands-on experience using modern cloud data platforms and transformation tooling; such as Snowflake, dbt, AWS or similar technology stack.\n\nExperience designing event taxonomies, schemas, data contracts, versioning and metadata for web or product telemetry, including semi-structured JSON data.\n\nStrong understanding of digital analytics and conversion measurement, including behavioural funnels, search and booking progression, landing and entry-point performance, attribution, journey progression and behaviouralKPIs.\n\nExperience modelling high-volume event data into reusable facts, dimensions and data products that support both detailed investigation and governed business reporting.\n\nUnderstanding of RUM(real user monitoring)and observability concepts including metrics, logs, traces, correlation, instrumentation and the relationship between technical performance and customer experience.\n\nExperience implementing data quality, automated testing, schema-change controls, privacy, classification, access, retention and lifecycle practices for telemetry or behaviouraldata.\n\nStrong stakeholder and partner communication skills, with the ability to explain complex event and telemetry data to analysts, engineers, product teamsand non-technical consumers.\n\nWorking knowledge of Git, CI/CD, automated testingand documentation practices, with a track recordof improving engineering standards and enabling others to work independently.","description_format":"text","description_chars":6286,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Ireland","iso":"IE","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Travel & Tourism","Car Rental"],"lifecycle":[{"event":"open","at":"2026-09-25T08:26:24Z"}],"visa":[],"liveness":{"score":87,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.866,"p_room":1,"age_days":13,"expected_fill_days":41,"reasons":["conf:0","velocity","win:early"],"computed_at":"2026-10-09T06:01:00Z"},"pay":null,"html_url":"https://alion.io/job/cartrawler-senior-data-engineer-digital-behavioural-telemetry","json_url":"https://alion.io/job/cartrawler-senior-data-engineer-digital-behavioural-telemetry.json","meta":{"generated_at":"2026-10-10T00:39:53Z","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","counted_by":"address","units_charged":1,"used_today":1053,"day_limit":5000,"remaining_today":3947,"minute_limit":60,"resets_at":"2026-10-11T00:00:00Z"}},"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":56804},"rest":"https://alion.io/mcp/rest/get_company?id=56804"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcartrawler-senior-data-engineer-digital-behavioural-telemetry"},{"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%2Fcartrawler-senior-data-engineer-digital-behavioural-telemetry"},{"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%2Fcartrawler-senior-data-engineer-digital-behavioural-telemetry"},{"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/cartrawler-senior-data-engineer-digital-behavioural-telemetry\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcartrawler-senior-data-engineer-digital-behavioural-telemetry"}]}
