Full Stack Developer

Company descriptionUranion is a software house specialising in AI and cloud infrastructure for enterprise clients.We build production-ready systems that integrate AI, automation, and cloud-native architectures: RAG-based knowledge management platforms, multi-cloud Kubernetes deployments, intelligent CRMs, and semantic search engines.Our stack is intentionally modern.Rust for performance-critical systems, Nix for reproducible environments, Dioxus for frontend WASM applications, vector databases (LanceDB, QDrant), and zero-trust networking with OpenZiti.We work fully remote with a lean, expert team where architectural decisions are collaborative, not hierarchical.We prioritise code quality, ownership, and solving real technical problems over bureaucratic processes.Role descriptionThis is a full-time, fully remote Full Stack Developer position with a focus on modern Rust-based web development and AI-integrated applications.You will work on diverse projects: building RAG systems that turn 30 years of email archives into queryable AI knowledge bases, developing multi-cloud container orchestration platforms, creating intelligent CRMs from scratch, and integrating generative AI capabilities into enterprise workflows.What you'll actually do:Develop frontend applications using Dioxus (Rust/WASM framework) and DaisyUI, transitioning from traditional React/Angular if neededBuild backend services in Rust using SpinFramework, managing state with LanceDB, QDrant, PostgreSQL, and RedisDesign data models and system architectures for new AI-powered applicationsUse Nix to create reproducible development and deployment environments across the teamCollaborate on RAG (Retrieval-Augmented Generation) architectures, embedding generation, and vector search optimisationParticipate in technical decision-making—we don't have \"architects\" who dictate from aboveTech stack highlights:Core: Rust, Nix, Dioxus, SpinFrameworkData/AI: LanceDB, QDrant, Arrow, OpenDAL, Python (for ML prototyping)Infrastructure: Kubernetes/K3S, OpenZiti, Docker, ArgoCDUI: DaisyUI, Tailwind CSSQualifications mindset (most important):Algorithmic thinking: You understand data structures, computational complexity, memory management—not just framework patternsFast learner with curiosity beyond work hours: You learn new technologies because you genuinely want to, not just because a ticket requires itCritical AI tool usage: You use Copilot/ChatGPT/Cursor to accelerate work, but you validate output and understand when it's wrongOwnership mentality: You care about the quality of what you ship, not just closing ticketsComfortable verbalizing technical reasoning: You can explain your thought process during pair programming and code reviewsTechnical requirements:2-3+ years professional experience building real web applications (enterprise dashboards, CRMs, SaaS platforms, not just landing pages)Strong frontend experience with React, Angular, or similar modern frameworksBackend sensibility: You've built APIs, managed application state, integrated databases, and understand server-side logicWillingness to learn Rust and Nix.We don't expect you to be an expert on day one, but you should be excited to dive inComfortable with Linux CLI, build systems, and DockerFluent English (Italian is a plus for internal communication)Bonus points:Experience with Rust, WebAssembly (WASM), or Dioxus/Yew/LeptosFamiliarity withNix or other reproducible build systemsKnowledge of RAG systems, vector databases, or embedding modelsBackground inmicroservices, gRPC, or distributed systemsExperience with Kubernetes or cloud-native architecturesNote: This is a fully remote position, not on-site in London.We have team members across Europe working in their own time zones.
