Systems/processes are recruitment practices, CV's, Documents, power intelligent automation within the healthcare industry. \nDuties & Responsibilities \nBuild and operate Python AI/ML services that score and match workers to jobs and surface results into the product.\nDesign and implement best practices for production AI: evaluation harnesses, guardrails, monitoring, reproducibility and cost control.\nDesign and improve retrieval and matching pipelines: embeddings, vector search and taxonomy-driven scoring.\nIntegrate large language models for extraction, summarisation, classification and intelligent automation (use AWS Bedrock today, but you should be comfortable choosing and switching providers).\nBuild and train our own in-house models where they outperform or reduce reliance on third-party APIs: data preparation, training and fine-tuning, evaluation and deployment.\nOwn data quality for AI features, for example ensuring embedding and taxonomy data is correct so scores are meaningful rather than degenerate.\nPartner with full stack engineers to expose AI capabilities through clean APIs, and with platform engineers on deployment and cost.\nMonitor accuracy, latency and cost in production, and iterate based on real outcomes.\nDesired Experience & Qualification \n3 to 6 years building software, with strong, production-grade Python.\nHands-on experience building and shipping ML, NLP or LLM-powered features, not only research or notebooks.\nThe ability to design and implement best practices for AI systems: evaluation, guardrails, monitoring, reproducibility and cost control.\nPractical understanding of embeddings, semantic / vector search and retrieval-augmented generation (RAG).\nExperience integrating LLMs from any provider (for example Anthropic, OpenAI, AWS Bedrock or open models) into real applications.\nThe ability to build, train and fine-tune in-house models, not only consume third-party APIs: dataset preparation, training, evaluation and serving.\nComfortable building APIs and working with relational data (FastAPI and PostgreSQL; similar tools transfer well).\nSolid grasp of prompt design, evaluation, and the failure modes of LLM and scoring systems, and able to reason about why a model behaves the way it does in production.\nNice to have \nFamiliarity with managed LLM platforms (for example AWS Bedrock), including model access, secure cross-account access and cost management.\nDeep experience with model training frameworks (PyTorch, TensorFlow or Hugging Face) and serving custom models at scale.\nFamiliarity with vector databases / pgvector and building taxonomy or ontology-driven scoring.\nExperience designing agentic systems, tool-use, or multi-step LLM workflows.\nWorkflow orchestration / automation tooling (for example Airflow, Prefect or similar).\nMLOps experience: model/version tracking, evaluation harnesses, monitoring and observability for AI.\nComfort with containers, Kubernetes, and deploying Python services in production.\nBackground in matching, search, ranking, or recommendation systems.\nDomain experience in healthcare, recruitment or HR-tech.\n Desired Skills: \n 3 to 6 years building software with strong production-grade Python\n Hands-on experience building and shipping ML\n NLP or LLM-powered features\n The ability to design and implement best practices for AI systems:\n Domain experience in healthcare\n recruitment or HR-tech.\n Desired Work Experience: \n 5 to 10 years\n Desired Qualification Level: \n Degree","description_format":"text","description_chars":3567,"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":[],"lifecycle":[{"event":"open","at":"2026-11-02T21:51:00Z"}],"visa":[],"liveness":{"score":52,"band":"ok","label":"Likely open","p_open":1,"p_active":0.516,"p_room":1,"age_days":6,"expected_fill_days":26,"reasons":["seen:6","agency","win:early"],"computed_at":"2026-11-08T05:47:12Z"},"pay":null,"html_url":"https://alion.io/job/sompisi-calibre-solutions-ai-engineer","json_url":"https://alion.io/job/sompisi-calibre-solutions-ai-engineer.json","meta":{"generated_at":"2026-11-09T02:00:29Z","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":4252,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-10T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":4497032},"rest":"https://alion.io/mcp/rest/get_company?id=4497032"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsompisi-calibre-solutions-ai-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Fsompisi-calibre-solutions-ai-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fsompisi-calibre-solutions-ai-engineer"},{"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/sompisi-calibre-solutions-ai-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsompisi-calibre-solutions-ai-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3641611}},{"tool":"search_jobs","arguments":{"company":4497032,"detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3641611},"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);
