Our requirements

  • 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.

Optional

  • 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.

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.

About the project

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.
