They also support product teams with data for analytics tasks.\nWhat you will do\nBuild and operate the online serving data pipeline end-to-end, from raw log ingestion and feature extraction to model scoring and low-latency serving for Deep Learning models that drive ads distribution;\nCollaborate with Data Scientists to assess new requirements, surface data and resource constraints, propose alternatives, and proactively source new data to improve model quality;\nConnect and process data across teams, including dev and product, to enable shared use and analytics;\nOptimize large-scale storage and feature serving to sustain high-throughput query and aggregation cycles;\nSet up monitoring, alerting, and dashboards so pipeline issues are caught early and stakeholders can track data quality, model performance, and system health;\nEstablish solid design and engineering best practices for both technical and non-technical stakeholder.\nWhat you need\n3+ years of working experience in Big Data and production data pipelines;\nStrong command of Python for high-performance data processing; Scala is a plus;\nProficiency with orchestration and deployment workflows: Airflow, Docker/containerization, CI/CD, and Kubernetes (K8s);\nProven ability to optimize storage and query performance on columnar stores (e.g., ClickHouse) through partitioning, indexing, and compression;\nExperience building dashboards and observability with tools such as Streamlit or Metabase;\nSolid skills in data ingestion, transformation, and analysis, and in synchronizing data across diverse databases for batch and stream processing;\nA proactive, research-driven mindset toward the global technology landscape and a strong willingness to adopt emerging technologies, AI-driven tools, and AI-native development in the workflow;\nIntellectual curiosity, effective communication, and strong stakeholder collaboration skills.\nNice to have\nWorking knowledge of data science / ML workflows and the model lifecycle (training, evaluation, serving), and how data engineering decisions affect model accuracy;\nDomain knowledge of digital ads or experience in the advertising field;\nExperience deploying and serving LLMs in production (e.g., inference optimization, scalable serving infrastructure, latency/throughput tuning).","description_format":"text","description_chars":2540,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Messaging Apps","Social Networks"],"lifecycle":[{"event":"open","at":"2026-09-26T20:12:57Z"},{"event":"close","at":"2026-10-07T11:32:09Z"},{"event":"reopen","at":"2026-10-13T14:38:31Z"}],"visa":[],"liveness":{"score":43,"band":"fade","label":"Fading","p_open":1,"p_active":0.717,"p_room":0.6,"age_days":68,"expected_fill_days":72,"reasons":["conf:4","win:late","crowd:"],"computed_at":"2026-10-14T06:34:16Z"},"pay":null,"html_url":"https://alion.io/job/zalo-senior-data-engineer-adtima","json_url":"https://alion.io/job/zalo-senior-data-engineer-adtima.json","meta":{"generated_at":"2026-10-14T06:50:42Z","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":8137,"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":183385},"rest":"https://alion.io/mcp/rest/get_company?id=183385"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fzalo-senior-data-engineer-adtima"},{"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%2Fzalo-senior-data-engineer-adtima"},{"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%2Fzalo-senior-data-engineer-adtima"},{"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/zalo-senior-data-engineer-adtima\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fzalo-senior-data-engineer-adtima"}]}
