You'll write real pipeline code on real projects, working with business leads, analysts, and data scientists to understand the domain, then with engineers to build data products that make decisions better.\nHere's the honest framing: you're learning the agent-native craft, not owning cutover. Agents handle much of the repetitive discovery and validation work that used to fill junior engineers' days, which means your time goes further into Spark, ETL design, and understanding why data quality decisions matter to the business. If you care about the quality of the metrics a business runs on, and you want your solutions to scale to bigger questions, this is the seat.\nWhat you will do?\nWrite efficient code in the technology chosen for the project - Spark or Apache Beam, for example.\nExplore new technologies and learn new techniques to solve business problems creatively.\nCollaborate across engineering and business teams to build better data products and services.\nDeliver projects with the team and keep customers updated on time - shipping on schedule is a habit you'll build early here.\nWhat we are looking for?\nExposure to Apache Spark.\nExposure to ETL concepts using pySpark and SparkSQL.\nExposure to SQL queries and stored procedures, and the appetite to work on challenging projects with a mentor-oriented leader.\nYou will be preferred if you have\nPrior experience in working on AWS EMR, Apache Airflow\nAWS Certified Big Data - Specialty certification, Azure Certification, Snowflake Certification\nCloudera or Hortonworks Certified Big Data Engineer\nUnderstanding of DataOps Engineering\nHow we work?\nMactores delivers through agents plus forward-deployed engineers. Aedeon, the agent platform we deploy, does the repetitive majority source discovery, schema mapping, validation harnesses while engineers make the architecture and cutover calls. As an intern you work inside that model from day one: you'll see how a data platform actually reaches production, and you'll learn to work with agents as tooling rather than treating them as a threat or a magic trick. The engineers who grow fastest here are the ones who master that combination.","description_format":"text","description_chars":2324,"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":"India","iso":"IN","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Cloud Consulting & Migration","Data Engineering & Migration Services"],"lifecycle":[{"event":"open","at":"2026-09-02T17:39:14Z"},{"event":"close","at":"2026-10-22T13:36:25Z"}],"visa":[],"liveness":null,"pay":null,"html_url":"https://alion.io/job/mactores-data-engineer-intern","json_url":"https://alion.io/job/mactores-data-engineer-intern.json","meta":{"generated_at":"2026-10-22T18:32:38Z","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":1218,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-23T00:00:00Z"}},"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":6938},"rest":"https://alion.io/mcp/rest/get_company?id=6938"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmactores-data-engineer-intern"},{"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%2Fmactores-data-engineer-intern"},{"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%2Fmactores-data-engineer-intern"},{"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/mactores-data-engineer-intern\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmactores-data-engineer-intern"}]}
