Acquisition is slow, paper-heavy, and consequential; we're using agentic AI to make it faster and more defensible without lowering the bar on rigor. Your work will ship into production environments where the decisions really matter.\nWe’re looking for a talented, self-driven Agentic AI Engineer to join our core engineering team and help build the next generation of autonomous AI systems that power our acquisition platform. You will design, develop, and deploy sophisticated multi-step AI agents capable of reasoning over complex procurement documents, managing long-horizon workflows, and delivering precise, defensible outputs in high-stakes environments.\nThis is a hands-on individual contributor role. You will work closely with our ML researchers, full-stack engineers, and product teams to ship agentic features that directly impact how government agencies and enterprise organizations acquire capabilities. Your work will be used in production environments handling sensitive and consequential decisions, so rigor, reliability, and security-consciousness are as important as innovation.\nNote: This is a Hybrid Role - 3 days per week in our office in McLean, VA\nWhat You’ll Do\nAgent Design & Development\nArchitect and build multi-agent systems and autonomous workflows for document analysis, requirement extraction, RFP response generation, and procurement pipeline automation.\nDesign and implement agentic orchestration using frameworks such as LangGraph, AutoGen, CrewAI, or custom-built solutions tailored to Rohirrim’s platform requirements.\nDevelop tool-using, reasoning, and planning capabilities that enable agents to decompose complex acquisition problems into executable subtasks.\nBuild robust human-in-the-loop and approval gates for high-stakes decision points within automated workflows.\nGraph RAG & Document Intelligence\nDesign and optimize Retrieval-Augmented Generation (RAG) pipelines to ground agent outputs in authoritative procurement data, regulations (FAR/DFARS), past performance records, and institutional knowledge.\nImplement advanced retrieval strategies including hybrid search, re-ranking, and context-aware chunking across large, heterogeneous document corpora.\nDevelop document parsing and structuring pipelines for RFPs, SOWs, PWS, solicitations, and other complex government acquisition artifacts.\nLLM Integration & Evaluation\nSelect and integrate appropriate LLMs (commercial and open-source) for specific agent tasks, balancing capability, latency, cost, and security requirements.\nBuild evaluation frameworks to systematically test agent accuracy, hallucination rates, and task completion against procurement-specific benchmarks.\nImplement prompt engineering best practices, including structured outputs, chain-of-thought reasoning, and few-shot prompting optimized for acquisition workflows.\nPlatform & Infrastructure\nCollaborate with platform engineers to deploy agents in production with observability, logging, tracing, and graceful failure handling.\nContribute to shared tooling, internal SDKs, and reusable agent components that accelerate development across the engineering team.\nParticipate in architecture reviews, code reviews, and technical planning sessions with a focus on scalability and maintainability.\nWhat You’ll Bring\nRequired\n8+ years of software engineering experience, with at least 1 year focused on LLM applications, AI agents, or applied ML systems in production.\nStrong Python proficiency; experience building production-grade AI/ML pipelines.\nHands-on experience with LLM orchestration frameworks (LangChain, LangGraph, AutoGen or equivalent).\nDeep understanding of RAG architectures, vector databases (Pinecone, Weaviate, pgvector or similar), and embedding models.\nExperience integrating APIs from frontier model providers and tuning prompts for structured and reliable results\nStrong software engineering fundamentals: clean architecture, testing, observability, and version control best practices.\nPlusses\nExperience building AI products for regulated enterprise environments.\nFamiliarity with federal acquisition regulations (FAR, DFARS) or proposal management processes.\nExperience with fine-tuning or instruction-tuning open-source LLMs (LLaMA, Mistral, etc.).\nKnowledge of secure-by-design principles and air-gapped or FedRAMP-compliant deployment environments.\nActive Secret or TS/SCI security clearance (or ability and eligibility to obtain).\nExperience with cloud infrastructure on AWS, Azure, or GCP; containerization with Docker/Kubernetes.\nSuccess Profile\nA collaborative IC that is excellent at giving and receiving technical feedback, communicating trade-offs clearly, and elevating teammates.\nAbility to help define how agentic AI gets implemented in a SaaS company","description_format":"text","description_chars":4921,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":true,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["AI Agents","Procurement & Spend Management"],"lifecycle":[{"event":"open","at":"2026-09-11T23:26:52Z"}],"visa":[],"liveness":{"score":11,"band":"cold","label":"Long shot","p_open":1,"p_active":0.408,"p_room":0.28,"age_days":117,"expected_fill_days":29,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-20T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/rohirrim-senior-ai-engineer","json_url":"https://alion.io/job/rohirrim-senior-ai-engineer.json","meta":{"generated_at":"2026-10-21T00:48:11Z","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":1272,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"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":688217},"rest":"https://alion.io/mcp/rest/get_company?id=688217"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Frohirrim-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%2Frohirrim-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%2Frohirrim-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/rohirrim-senior-ai-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Frohirrim-senior-ai-engineer"}]}
