You would take ownership of the full RAG pipeline, from document ingestion and chunking strategy through retrieval design, evaluation, model integration, and stateful agent workflows. The work sits at the intersection of applied LLM systems, backend engineering, and production architecture, so it will suit someone who enjoys turning complex ideas into robust, scalable systems that work in the real world. You’ll join a team that values strong ownership, thoughtful system design, practical problem solving, and collaboration. The environment is engineering-led and hands-on, with a focus on building solutions that are not only technically interesting, but also observable, maintainable, and trustworthy in production.\nKey Responsibilities:\nChunking and ingestion architecture - deterministic, validation-gated pipelines handling diverse enterprise document types with indexing and contextual enrichment\nRetrieval pipeline - Vector search, BM25 hybrid retrieval, RRF re-ranking, embedding model selection and optimisation\nAgent orchestration - designing stateful, multi-step agent workflows with LangGraph; building chains and tool-use patterns with LangChain\nObservability - tracing, debugging, and monitoring pipeline performance end-to-end with LangSmith; catching retrieval and reasoning failures before they reach users\nModel evaluation and tuning - RAGAS-based evaluation frameworks, benchmarking retrieval recall and answer faithfulness, iterating toward production quality\nOpen-weight LLM deployment - evaluating and shipping models (Llama 4, Qwen3, MiMo-V2) under memory and latency budgets via Amazon Bedrock and self-hosted inference\nWorkflow orchestration - async pipeline design with Temporal.io; containerised deployment on Kubernetes via GitLab CI\nRequired Qualifications:\nStrong software engineering skills in .NET and/or Python, with experience building production-grade APIs and services\nApplied algorithmic problem solving, including search, ranking, clustering, and data extraction/transformation pipelines\nSolid understanding of LLM architectures and trade-offs (e.g. GPT-family, Claude, Llama, and similar models)\nExperience integrating LLM and agent APIs (e.g. Azure OpenAI, OpenAI API, Claude API, Amazon Bedrock)\nDesign and implementation of agent-based systems for automation, orchestration, and decision support\nExperience working with relational, document, and graph databases, including data modeling and querying\nWeb data ingestion experience, including web scraping, schema extraction, and handling changing source structures\nExperience building reliable, scalable, maintainable AI systems, including logging, error handling, and performance considerations\nNice to have:\nFine-tuning and preference optimization techniques (e.g. supervised fine-tuning, RL-style approaches via APIs)\nDesigning pipelines that convert unstructured data into reliable structured representations\nExposure to event-driven or background processing architectures for long-running AI workflows\nExperience contributing to or operating AI-powered systems in production","description_format":"text","description_chars":3244,"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":["UI/UX Design","IT Consulting & Digital Transformation","IT Outsourcing & Dedicated Teams","Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-10-11T01:06:20Z"}],"visa":[],"liveness":{"score":33,"band":"fade","label":"Fading","p_open":1,"p_active":0.595,"p_room":0.55,"age_days":53,"expected_fill_days":38,"reasons":["conf:1","win:tail"],"computed_at":"2026-10-12T03:47:41Z"},"pay":null,"html_url":"https://alion.io/job/htec-senior-ai-engineer","json_url":"https://alion.io/job/htec-senior-ai-engineer.json","meta":{"generated_at":"2026-10-12T03:47:41Z","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":5992,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-13T00:00:00Z"}},"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":55786},"rest":"https://alion.io/mcp/rest/get_company?id=55786"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhtec-senior-ai-engineer"},{"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%2Fhtec-senior-ai-engineer"},{"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%2Fhtec-senior-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/htec-senior-ai-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhtec-senior-ai-engineer"}]}
