Someone who does not see building AI systems and operating them as a trade-off, but as two things that make each other better.\nDo you get energy from designing LLM-powered agents and RAG pipelines while staying just as sharp on monitoring, CI/CD and safe rollouts once they're live? Then you will probably feel right at home here.\nRequirements\nWe're on the lookout for a Mid-Level AI Systems Engineer who bridges AI engineering and MLOps. Someone who loves getting hands-on with LLMs, agents, and RAG pipelines, and who cares just as much about what happens once a model reaches production as about building it in the first place. In this role, you'll design, build, deploy, and operate production-grade AI systems, with a strong focus on generative AI, LLM-based applications, and reliable machine learning operations. In practice your time is split roughly between 60-70% AI Engineering and 30-40% MLOps.\nIn this role you sit at the intersection of engineering and operations, working across teams and disciplines. You'll report to the Head of ML at Sagacify and collaborate with the wider Sagacify and Craftzing delivery organisation. A role that can naturally grow towards a Team Lead position over time.\nWhat you'll do\nAI Engineering (60-70%)\nOrchestrate AI system components: LLMs, vector databases, APIs, orchestration layers, and user interfaces\n\nDevelop autonomous agents and conversational systems that can plan actions and interact with external tools or APIs\n\nBuild and optimise RAG pipelines connecting enterprise data sources to LLMs for grounded, contextualised, reliable answers\n\nEvaluate system quality through generative AI metrics, coherence tests, and production monitoring (latency, API costs, bias)\n\nDeploy and scale solutions with strong attention to latency, security, reliability and cost efficiency\n\nKeep an eye on the ecosystem for new models, frameworks and techniques, including open-source tools such as LangChain, LangGraph, Langfuse, etc.\n\nPerform prompt and context engineering to improve output quality, reduce hallucinations, and manage conversational state effectively\n\nMLOps (30-40%)\nBuild and maintain automation for model deployment, including CI/CD pipelines and automated testing\n\nContinuously monitor model performance in production, including drift detection and quality metric tracking\n\nManage updates of libraries, models, and related dependencies in production environments\n\nEnsure versioning, reproducibility and safe rollout of models and AI services\n\nCollaborate closely with ML engineers, developers, DevOps and infrastructure teams for smooth delivery\n\nStay current with the latest MLOps practices, tools and platform components\n\nYou stay in the code, you stay curious about what happens after deployment, and you keep learning as you go.\nWhat you'll work with\nCore technologies :\nPython\n\nOpenAI API, Hugging Face Transformers\n\nLangChain, LangGraph, Langfuse\n\nFastAPI or Flask, Docker, Kubernetes, CI/CD pipelines\n\nCloud GPU\n\nAWS (S3, SQS, IAM, RDS, etc.)\n\nCursor\n\nBonus points for experience with :\nTypeScript\n\nAzure\n\nAI-native engineering workflows: hands-on experience using AI coding agents and AI-assisted development environments (Cursor, Claude Code, Windsurf, Copilot, etc.), including context engineering, subagent orchestra…\n\nWho we're looking for\nYou have 3 to 5 years of experience in AI/ML engineering or related fields\n\nYou have a solid understanding of LLM fundamentals: Transformers, attention mechanisms, generation parameters and fine-tuning approaches\n\nYou have strong problem-solving ability and algorithmic creativity\n\nYou communicate clearly with both technical and non-technical stakeholders\n\nYou have a team spirit and enjoy collaborating across multiple roles\n\nYou bring rigour, responsiveness and a good incident-handling mindset\n\nYou're autonomous, curious, and quick to learn new tools\n\nYou can communicate fluently in Dutch, English and French, or at least the first two languages\n\nDon’t worry if you don’t tick every single box, what matters most is the right mindset and a drive to learn. If you think we’re a match, we’d love to hear from you.\nWhy you'll love working here\nSagacify is part of Craftzing, and together we build AI solutions that create lasting impact for our clients. You will be part of a team of enthusiasts who love to learn, continuously develop new skills and fast-track our customers' AI journey across various industries.\nAt Craftzing and Sagacify, you get the trust and space to do your best work - in a human-sized environment with real team spirit, flexible working and room to take ownership.","description_format":"text","description_chars":4774,"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":[{"language":"Dutch","level":"All levels","optional":false},{"language":"French","level":"All levels","optional":false}]},"benefits":["Flexible schedule"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["IT Consulting & Digital Transformation"],"lifecycle":[{"event":"open","at":"2026-09-11T00:57:10Z"}],"visa":[],"liveness":{"score":9,"band":"cold","label":"Long shot","p_open":1,"p_active":0.316,"p_room":0.28,"age_days":62,"expected_fill_days":25,"reasons":["conf:0","stale_co","win:tail","crowd:"],"computed_at":"2026-11-03T05:54:40Z"},"pay":{"stated_usd_annual":67392,"is_top_pay":false},"html_url":"https://alion.io/job/craftzing-ai-systems-engineer-sagacify","json_url":"https://alion.io/job/craftzing-ai-systems-engineer-sagacify.json","meta":{"generated_at":"2026-11-03T09:47:43Z","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":13870,"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":673386},"rest":"https://alion.io/mcp/rest/get_company?id=673386"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcraftzing-ai-systems-engineer-sagacify"},{"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%2Fcraftzing-ai-systems-engineer-sagacify"},{"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%2Fcraftzing-ai-systems-engineer-sagacify"},{"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/craftzing-ai-systems-engineer-sagacify\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcraftzing-ai-systems-engineer-sagacify"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":690598}},{"tool":"search_jobs","arguments":{"company":"craftzing.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":690598},"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.
