Remote-first work with opportunities for technical growth, architecture influence, and long-term cooperation. 🗂️ Requirements: 3+ years of commercial fullstack engineering experience, Strong Java proficiency, Strong Spring Boot proficiency, Strong React proficiency, Experience with modern frontend patterns, Solid SQL skills, Database design experience, Experience with structured and unstructured data models, Hands-on GitHub experience, Hands-on GitHub Actions experience, Familiarity with Azure cloud services, Experience with CI/CD pipelines, Fluent English 📃 Skills: Java, Spring, SpringBoot, React, Next.js, Tailwind, SQL, GitHub, GitHubActions, Azure, CI/CD, REST, APIs 🏢 Description: Why Join Us At Cloudfide, we engineer solutions where data truly becomes an accelerator for innovation. We build and evolve large-scale Big Data and cloud-native platforms for global clients, including leaders in retail and the Fortune 500. We process massive, complex datasets, operate fully in the cloud ecosystem, and work with the latest technologies, including AI, ML, MLOps, and modern data architectures. Our projects have measurable, real‑world impact - from enhancing customer experiences at scale to empowering data-driven decision-making in high‑visibility global organizations. As we continue to grow, you'll have the opportunity to shape solutions, mentor others, drive architecture decisions, and take ownership of strategic initiatives. Opportunity Overview As a Mid/Senior Fullstack Engineer (Java/React), you will work on a custom-built platform for a Fortune 500 client - a sophisticated asset management and organization system handling diverse, high-volume data: images, 3D models, PDFs, structured datasets, and more. The platform ingests large, continuously growing volumes of data, supports rich tagging and classification, and is built entirely from scratch with a custom frontend and backend. This is a genuine full-stack role on a project where both sides of the stack matter equally. You'll have direct ownership over features end-to-end, work closely with the client, and help shape a platform that sits at the intersection of data engineering and user experience. Expect a collaborative, AI-forward environment where thinking outside the box is encouraged and your proactivity is genuinely valued. You'll join a team of passionate engineers who value technical excellence, collaboration, and continuous growth. Your Responsibilities Building and evolving scalable backend services using Java and Spring Boot, including REST APIs, business logic, and integrations. Developing modern, responsive frontend interfaces with React, Next.js, and Tailwind CSS. Taking full end-to-end ownership of features - from backend data modeling through to UI delivery - without requiring handoffs. Designing and working with databases handling both structured and unstructured asset data, writing solid, optimized SQL. Managing deployments and CI/CD pipelines using GitHub Actions and Azure cloud services. Making pragmatic build-vs-reuse decisions - knowing when a custom solution adds value and when it doesn't. Collaborating clearly with both technical peers and non-technical stakeholders, translating between business needs and engineering solutions. Contributing to code reviews, architectural discussions, and continuous improvement of the codebase. Leveraging AI tools in day-to-day work to enhance productivity and output quality. What We're Looking For 3+ years of commercial experience as a fullstack engineer with real depth on both backend and frontend - not a specialization in one with tolerance for the other. Strong proficiency in Java and Spring Boot - non-negotiable. Strong proficiency in React and modern frontend patterns (Next.js experience a strong plus). Solid database and SQL skills across both structured and unstructured data models. Hands-on experience with GitHub and GitHub Actions for version control and CI/CD. Familiarity with Azure cloud services and cloud-native deployment practices. Pragmatic problem-solving mindset - able to navigate ambiguity, prioritize effectively, and deliver without excessive hand-holding. Clear communicator across technical and non-technical audiences. Fluent English, able to collaborate effectively in an international environment. Nice to Have Experience with Tailwind CSS. Familiarity with asset management, DAM systems, or platforms handling large volumes of mixed-type files. Experience working with unstructured or semi-structured data at scale. Knowledge of web application security best practices. Azure DevOps familiarity.
