The platform brings together data from multiple business systems and puts AI agents on top of it, so that business teams get actionable insights and automated workflows instead of manual routines.\nRequirements\nWhat You'll Do\n Integrate data from multiple business sources (CRM, analytics, BI) into a single, cohesive data layer\nBuild and deploy AI agents that execute specific business tasks: signal analysis, pricing, content/SEO, data classification and tagging\n Develop MCP (Model Context Protocol) servers: dedicated, read-only, domain-specific servers that expose data to agents and tools\nDo data engineering work: schema design, ETL and synchronization from external systems, and ensuring data quality and consistency\nContribute to the agent platform architecture: routing layer, cost control, access policies, and telemetry for LLM calls\nDesign and build backend APIs connecting the data layer with agents and front-end applications\nCreate user-facing tools for business teams, driven by data and agent-generated insights\nMaintain infrastructure: containerization, database management, monitoring, and observability\n Document architectural decisions and keep strict contracts between system layers\nTech Stack\nPython · FastAPI · Agno (agent framework) · MCP · PostgreSQL · Docker / Docker Compose · Next.js\nWhat we are looking for:\nSolid commercial experience (approx. 2 years) in backend development with Python\nHands-on experience with FastAPI or a comparable modern web framework\nGood knowledge of PostgreSQL: schema design, query writing, and optimization\nExperience building and consuming REST APIs\nUnderstanding of ETL and data synchronization concepts, and of how to keep data consistent across systems\nWorking knowledge of Docker and Docker Compose\nPractical experience with LLMs and prompt writing; interest in building agent-based systems\nComfort working with agentic AI tools (e.g., Claude Code) in daily development, and the discipline to critically verify their output\nAbility to write clear technical documentation\nGood communication skills and confidence working directly with client-side teams\nEnglish level sufficient for daily communication with the client (B2+ / Upper-Intermediate)\nNice to Have\nExperience with agent frameworks (Agno, LangChain, LlamaIndex, or similar)\nFamiliarity with MCP (Model Context Protocol)\nBasic Next.js / React skills for working on front-end applications\nExperience with observability and monitoring tools\nExperience integrating with CRM, analytics, or BI systems\nBackground in enterprise or consulting projects\nWhat do we mean by freelance?\nRead more at Monterail Tech Network","description_format":"text","description_chars":2794,"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":[{"language":"English","level":"All levels","optional":false}]},"benefits":[],"hiring_locations":[{"name":"Poland","iso":"PL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Mobile App Development Services","Web Development Services","Custom Software Development"],"lifecycle":[{"event":"open","at":"2026-10-01T07:15:06Z"}],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":2,"expected_fill_days":26,"reasons":["conf:3","win:early"],"computed_at":"2026-10-02T03:24:01Z"},"pay":null,"html_url":"https://alion.io/job/monterail-backend-ai-developer-freelancer","json_url":"https://alion.io/job/monterail-backend-ai-developer-freelancer.json","meta":{"generated_at":"2026-10-02T03:24:01Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":4676,"day_limit":5000,"remaining_today":324,"minute_limit":60,"resets_at":"2026-10-03T00:00:00Z"}}}
