At the core of the company is the Market Model - a proprietary AI-powered model delivering accurate, granular demand predictions with 96% forecast accuracy and real-time decision intelligence for commercial teams. Built on a glass-box architecture, it uses market data - not personal data - with full transparency into logic and outcomes. First deployed in global aviation, the technology is industry-agnostic and scales across volatile markets. Fetcherr delivers a consistent average profit uplift of 7%, with corporate partners including Delta, Virgin Atlantic, WestJet, Viva, and Azul.\nWe are seeking an experienced Data Science Team Lead to lead our data science and data engineering efforts and oversee a team of skilled data engineers. This role combines hands-on technical leadership and team management, with responsibilities that include building and scaling data infrastructure to power real-time pricing, large-scale data pipelines, and machine learning products.\nThe Price Optimization (PO) team is where insights become decisions. We work with large-scale customer data and market predictions - like demand forecasts - to drive revenue management decisions that actually move the needle.\nAt our core, we build and maintain the decision-making engine. That means designing the data pipelines that bring customer data in, and running it through an optimization engine that simulates the market - weighing competition, pricing constraints, inventory availability, predictive models, and each client's unique business policies - to generate the best possible price recommendations. As the final step before recommendations reach the client, quality, reliability, and attention to detail aren't just nice to have. They're everything.\nYou will lead the team through architecture decisions, development, and deployment of mission-critical systems-while growing and mentoring a high-performing team.\nResponsibilities:\nManage a team of data scientists and data engineers responsible for building robust, scalable, and high-performance data pipelines and infrastructure.\n\nDesign, build, and maintain distributed data processing workflows (batch & streaming).\n\nDrive best practices for data quality, validation, testing, and observability.\n\nOwn and evolve Fetcherr's data architecture in alignment with business and product goals.\n\nManage sprint planning, task breakdown, code reviews, and performance feedback for your team.\n\nContribute hands-on to key development tasks and architecture decisions.\n\nRecruit, mentor, and grow the data science engineering team.\n\nRequirements\nProven experience as a Data Scientist.\n\nProven experience designing and maintaining large-scale data platforms (hundreds of TBs)\n\n3+ years of proven experience leading and managing a team of data science / data engineers (people management is required)\n\n4+ years of experience in data science, including a strong Python programming background, advanced SQL skills, and data modeling experience\n\nExpertise with data orchestration tools (Airflow, Prefect, or Dagster)\n\nCloud platform experience - GCP preferred (AWS/Azure acceptable)\n\nFamiliarity with Docker\n\nStrong communication, mentorship, and collaboration skills\n\nBSc/MSc in Mathematics/ physics/ statistics/ Computer Science.\n\nFluent English (spoken and written)\n\nNice to have:\nExperience with Google Cloud Platform tools (BigQuery, Dataflow, Pub/Sub)\n\nBackground working with ML pipelines or data science teams\n\nUnderstanding of data contracts, lineage, and versioning tools\n\nKnowledge of data structures and algorithms\n\nExperience optimizing pipelines and databases for performance and cost\n\nCI/CD pipelines (GitHub/GitLab)\n\nHands-on experience with distributed data frameworks (Apache Beam, Spark, or similar)\n\nExposure to airline, pricing, or GDS systems","description_format":"text","description_chars":3906,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"Advanced (C1)","optional":false}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-02T13:17:23Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":7,"expected_fill_days":30,"reasons":["seen:7","velocity","win:early"],"computed_at":"2026-10-10T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/fetcherr-data-science-team-lead","json_url":"https://alion.io/job/fetcherr-data-science-team-lead.json","meta":{"generated_at":"2026-10-11T03:07:56Z","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":514,"day_limit":5000,"remaining_today":4486,"minute_limit":60,"resets_at":"2026-10-12T00:00:00Z"}},"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":3861181},"rest":"https://alion.io/mcp/rest/get_company?id=3861181"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffetcherr-data-science-team-lead"},{"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%2Ffetcherr-data-science-team-lead"},{"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%2Ffetcherr-data-science-team-lead"},{"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/fetcherr-data-science-team-lead\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffetcherr-data-science-team-lead"}]}
