Our hand-picked team consists of passionate, collaborative, and forward-thinking individuals from all over the globe. We are passionate about making science easy and accessible to retailers, helping them get more value from people, data, and systems. We bring together expertise in retail, science, and scalable technologies to automate and enhance the quality of decision-making through software and consulting services.\nWe are proud to have a growing team of domain experts and data scientists, as well as a culture that fosters strong and long-lasting relationships with our clients.\nOur Locations:\nAtlanta, GA, US \nTunis, Tunisia\nIstanbul, Turkey\nParis, France\nPorto, Portugal\nOur values:\nBe nice and trustworthy\nPut our customers first\nSucceed together\nNever stop improving\nAre you ready to grow with us?To find out more about Cognira, please visit our website at www.cognira.com\nPlease submit your resume in English.\nI- Data Engineering Internship Topic:\nTopic 1: Data Pipelines with DuckDB\nCognira | Data Engineering Team\nABOUT THE INTERNSHIP\nOur data pipelines run every transformation with Apache Spark on cloud clusters, even when the data is small enough for one machine. This project moves suitable transformations to DuckDB, a fast SQL engine that runs on one machine, and lets them run on a developer’s laptop as well as in the cloud. The goal is faster and cheaper runs, and a shorter cycle to develop and test.\nWHAT YOU'LL WORK ON\nA short comparison of Spark and DuckDB on a few existing transformations, used to select which ones to move.\nDuckDB versions of selected transformations, with automated tests that prove they give the same output as the Spark versions.\nA tested way to run DuckDB transformations on Databricks, our cloud data platform, including the compute type, the dependencies and the access to our data. If Databricks does not support this directly, the project delivers a workaround.\nChanges to our pipeline orchestration, the system that defines and schedules each step, so that each step declares whether it runs on Spark or on DuckDB.\nOne command that runs a DuckDB transformation on a laptop, with sample data or with data read directly from cloud storage.\nOne version of the code for each transformation, which runs both locally and on Databricks without changes. \nWHAT YOU'LL BRING\nPython, SQL\nNICE TO HAVE\nDatabricks, Pyspark, DuckDB\nII- Data Science Internship Topics:\nTopic 1 : Semantic Similarity\nCognira | Data Science Team / Cognira\nABOUT THE INTERNSHIP\nUse an LLM to read product descriptions and assess with they should be considered substitues, complements, \"super-SKU\" components, or how they should fit into a product hierarchy together.\nWHAT YOU'LL WORK ON\nA science module that groups products into likely complements, substitutes and assembles a product hierarchy based on reading the descriptions of products.\nWHAT YOU'LL BRING\nData Analytics, Statistics, Python\nNICE TO HAVE\nDatabricks, Pyspark, Knowledge of LLM techniques, Natural Language Parsing familiarity\nTopic 2: AI Agent for Forecast Debugging\nCognira | Data Science Team\nABOUT THE INTERNSHIP\nUse an LLM agent to investigate differences between our batch and real-time forecasts: it explores the data, configurations and features with read-only tools, and proposes the most likely root cause with supporting evidence.\nWHAT YOU'LL WORK ON\nA prototype debugging agent, its toolset, and an evaluation framework measuring how often it finds the correct root cause on known issues.\nWHAT YOU'LL BRING\nPython, Data Analytics, Software Engineering\nNICE TO HAVE\nDatabricks, PySpark, Scala, LLM agents\nTopic 3: Deep Learning for Promotional Demand Forecasting\nCognira | Data Science Team\nABOUT THE INTERNSHIP\nEvaluate modern deep learning forecasting approaches, including pretrained time-series foundation models and transformer-based architectures, against existing production forecasting models. Investigate how incorporating richer product-level information can improve forecast accuracy, particularly for products with limited promotional history.\nWHAT YOU'LL WORK ON\nA reproducible benchmarking framework comparing deep learning models with production models, along with a detailed analysis of scenarios where deep learning methods improve promotional demand forecasting performance.\nWHAT YOU'LL BRING\nMachine Learning\nDeep Learning\nPython\nStatistics\nTime Series Forecasting\nDatabricks\nPySpark\nPyTorch\nLarge Language Models (LLMs)","description_format":"text","description_chars":4534,"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":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Retail & Pricing Analytics"],"lifecycle":[{"event":"open","at":"2026-10-27T17:24:25Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":2,"expected_fill_days":25,"reasons":["conf:3","win:early","comp:junior"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/cognira-data-engineer-intern-data-science-intern-pfe-2027","json_url":"https://alion.io/job/cognira-data-engineer-intern-data-science-intern-pfe-2027.json","meta":{"generated_at":"2026-10-30T21:10:04Z","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":11443,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"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":3894456},"rest":"https://alion.io/mcp/rest/get_company?id=3894456"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcognira-data-engineer-intern-data-science-intern-pfe-2027"},{"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%2Fcognira-data-engineer-intern-data-science-intern-pfe-2027"},{"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%2Fcognira-data-engineer-intern-data-science-intern-pfe-2027"},{"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/cognira-data-engineer-intern-data-science-intern-pfe-2027\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcognira-data-engineer-intern-data-science-intern-pfe-2027"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3346721}},{"tool":"search_jobs","arguments":{"company":"cognira.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3346721},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
