Senior Frontend Software Engineer

About the Project

We are building federated dataspaces inspired by initiatives such as Catena-X, Eclipse Tractus-X, and Gaia-X. Dataspaces will enable secure, standards-compliant, and sovereign data exchange across industrial and regulated ecosystems.

Our infrastructure will be designed to be provider-agnostic, supporting deployment across AWS, Azure, Google Cloud, and DigitalOcean. We aim to abstract the complexity of dataspace participation and deliver a seamless experience to data providers and consumers.

This is not limited to connector development. The scope includes the full architecture of the dataspace:

• Identity and trust management (DID, DAPS, OAuth2)
• Semantic metadata modelling and knowledge graphs
• Policy-based access control and contract negotiation
• Federated service discovery and data catalogues
• Data governance, auditability, and lifecycle management

You will be part of a cross-functional team contributing to an ambitious and highly impactful infrastructure platform from the ground up.

Role Overview

As a Senior Frontend Software Engineer, you will design and implement core user-facing components that enable secure, federated data exchange across domains. You will work closely with backend engineers, architects, designers, and product owners to ensure usability, security, and compliance with emerging European dataspace standards.

You will help create dashboards, data catalogues, policy managers, and contract negotiation interfaces with a focus on clean UX, accessibility, and scalability. You will also contribute to frontend toolkits and pattern libraries, helping define reusable components for dataspace applications. Collaboration with DevOps and QA teams will be integral.

Responsibilities

• Architect and implement complex frontend applications using TypeScript and React (or similar frameworks)
• Translate backend APIs and standards (e.g., Eclipse Dataspace Components) into intuitive UIs and workflows
• Integrate with OAuth2, OpenID Connect, and DID authentication providers
• Build interactive data catalogues, policy editors, and contract negotiation interfaces
• Ensure responsive, accessible design across devices and platforms
• Collaborate with backend, DevOps, and design teams for seamless API and dataintegration
• Participate in architecture design, code reviews, and knowledge sharing
• Document UI components, interfaces, and workflows for internal and external teams
