ppbPlease note that candidates must have the right to work in Italy and be based in the country for this role /b /p h3bAbout Exelab and Polyant /b /h3 pExelab builds custom, AI-powered solutions around real business needs. We work in small teams and use AI directly in how we design and build software. /p pYou will join the team building Polyant, our open-source, self-hosted runtime for AI agents. It brings together memory, retrieval over business documents, tool and plugin execution, messaging channels, permissions, tracing and cost control, behind an OpenAI-compatible API and an administration interface. /p pExplore the product before applying: /p pDocumentation: /p pCode: /p h3bThe role /b /h3 pYour primary focus will be Polyant: building features, improving reliability and helping shape the product over time. You will work across the platform, from the administration interface and runtime to the database and release pipeline, taking ownership of defined product areas in collaboration with the team. /p pThis role suits an engineer with solid experience shipping and maintaining production software, who can turn an ambiguous need into a scoped proposal, explain architectural trade-offs and follow a change through to release. Ownership includes maintenance, documentation and learning from failures. /p pResearch and experimentation are part of the work. You will test ideas around agent behaviour, retrieval, memory and evaluation, then turn promising results into maintainable product capabilities. The focus is software and agent engineering; model training, fine-tuning and MLOps are outside this role's scope. /p h3bWhat you will do /b /h3 ul lipDesign and deliver features end to end, from the data model and APIs to the user interface, tests and documentation.



/p /li lipOwn the technical decisions within your areas and make explicit trade-offs between user value, implementation effort, reliability and maintenance cost. /p /li lipDevelop agent capabilities such as tool execution, context management, retrieval and memory, with clear handling of failure modes. /p /li lipProtect a multi-tenant platform through sound authorization, data isolation, input validation and careful review. /p /li lipBuild regression tests and agent evaluations; use traces, latency and cost measurements to assess changes. /p /li lipKeep releases dependable through CI/CD, safe database migrations, deployment practices and investigation of production issues. /p /li lipUse AI coding agents deliberately: provide context and constraints, split work into reviewable changes, and verify generated code against the intended behaviour. /p /li lipPropose product improvements and share experiments, decisions and findings with the team. /p /li /ul h3bEssential experience and skills /b /h3 ul lipA track record of delivering production software and maintaining it over time, with examples of decisions and outcomes you can explain. /p /li lipStrong TypeScript and Node.js skills, plus practical React experience and the ability to work across backend and frontend. /p /li lipExperience with relational databases, API design, authentication and authorization. /p /li lipSound software design, debugging and refactoring skills,



supported by automated tests and code review. /p /li lipPractical experience with LLM APIs and agent workflows, including tool calling, structured output, context limits and the impact of cost and latency. /p /li lipAn evidence-based approach to reliability: you can explain how you test uncertain behaviour and investigate failures. /p /li lipPractical use of AI coding tools, with the ability to critically review their output. /p /li lipExperience with Git, CI/CD and deploying software; willingness to take responsibility for its behaviour after release. /p /li lipClear written communication, fluent professional Italian and working English. Based in Italy. /p /li /ul h3bUseful additional experience /b /h3 ul lipNext.js, NestJS, Drizzle ORM, PostgreSQL/pgvector, Docker or AWS CDK. These are parts of our stack; prior mastery of every tool is not required. /p /li lipRetrieval systems, embeddings, hybrid search, chunking or reranking. /p /li lipAgent evaluation, tracing, context compaction, lifecycle hooks, guardrails or MCP. /p /li lipMulti-tenant or self-hosted products, open-source contributions or developer-facing tools. /p /li /ul h3bHow we work and what you can expect /b /h3 ul lipA small team where your work contributes directly to a visible product and its technical direction. /p /li lipTechnical collaboration, regular feedback and knowledge sharing as you build deeper expertise in agent systems. /p /li lipRoom for focused experimentation, with a clear path from a hypothesis to a measured result and a product decision. /p /li lipA remote working environment in Italy, with ownership scoped to clear priorities and outcomes. /p /li /ul pSalary range: 40-50 K /p /p #J-18808-Ljbffr
