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. W e 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 with Nix or other reproducible build systemsKnowledge of RAG systems, vector databases, or embedding modelsBackground in microservices, 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.
