Accelerating the integration of generative AI solutions and AI agents into business processes. A strategic environment within the platform, with high-impact use cases in document analysis, credit, and finance.\nExpectations:\nStrong Python with extensive experience in Object-Oriented Programming and enterprise software design patterns.\nProven track record building asynchronous microservices and endpoints using FastAPI.\nHands-on practice in pytest (unit, functional, and integration testing for ML/LLM pipelines).\nBash scripts for automation, data handling, and container interaction.\nLLMs Architecture understanding proven by project portfolio.\nArchitecting multi-step, stateful agentic graphs using LangGraph or Google ADK.\nHands-on experience optimizing LLM pipelines programmatically using DSPy.\nPractical knowledge of deploying and running high-throughput open-weight models on GPU infrastructure using runtimes such as vLLM (experience with CUDA and fine-tuning is a strong plus).\nHands-on familiarity with automated build, test, and release pipelines (Jenkins).\nExperience setting up tracing, drift detection, and automated evaluations for generative workflows using tools like Phoenix Arize.\nDedication to shipping stable, secure code into flagship banking infrastructure where compliance, auditability, and data security are non-negotiable.\nGeneral Stack: Google ADK, LangGraph, DSPy, vLLM, FastAPI, Python, Pytest. Arize Phoenix. Kubernetes, Jenkins, GPUs.\nResponsibilities:\nDesign and develop LLM-based agentic solutions to automate complex business processes.\nWork closely with business teams to identify needs and drive the adoption of AI solutions.\nDevelop data extraction pipelines and implement evaluation and observability frameworks for AI agents.\nDeploy and industrialize models (LLMs, GPUs), ensuring quality through testing and DevOps best practices\nYou are taking full ownership in driving AI features.\nYou remember to respect the boundaries and non-deterministic nature of LLMs, communicate constraints clearly, and build robust safety rails.\nYou are a team player, communicate technical trade-offs cleanly with architects and business users, and enjoy mentoring peers.\nYou are testing ideas and PoCs quickly, validate feasibility with data and avoid technical debt.\nCareer Prospects:\nBuild expertise in Agentic AI architectures and the industrialization of LLMs in production. Work on high-visibility projects within the Investment Banking division.","description_format":"text","description_chars":2597,"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":"Poland","iso":"PL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["IT Consulting & Digital Transformation","IT Staffing & Staff Augmentation"],"lifecycle":[{"event":"open","at":"2026-10-28T14:12:30Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":5,"expected_fill_days":226,"reasons":["conf:3","velocity","win:early"],"computed_at":"2026-11-03T05:54:40Z"},"pay":{"stated_usd_annual":102000,"is_top_pay":false},"html_url":"https://alion.io/job/margo-senior-data-scientist-bn-28102026","json_url":"https://alion.io/job/margo-senior-data-scientist-bn-28102026.json","meta":{"generated_at":"2026-11-03T09:45:13Z","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":13792,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-04T00:00:00Z"}},"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":678262},"rest":"https://alion.io/mcp/rest/get_company?id=678262"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fmargo-senior-data-scientist-bn-28102026"},{"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%2Fmargo-senior-data-scientist-bn-28102026"},{"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%2Fmargo-senior-data-scientist-bn-28102026"},{"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/margo-senior-data-scientist-bn-28102026\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fmargo-senior-data-scientist-bn-28102026"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3400262}},{"tool":"search_jobs","arguments":{"company":"margo.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3400262},"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.
