As a Senior Technical Expert, you will be the technical cornerstone of our Data Marketplace —a platform built on Data Mesh principles. You will guide the evolution of a "shop-for-data" experience, moving our architecture from a robust Modular Monolith to a distributed Microservices ecosystem. You’ll be working with a cutting-edge stack (Java 21, AWS, AI-enhanced search) to ensure that "buying" digital assets is as seamless for our users as a consumer e-commerce experience. The end-goal is to build a comprehensive solution that enables FAIR data access to Digital Assets across the organization.
Key Responsibilities
Architectural Evolution: Lead the strategic transition from a modular monolith to microservices, ensuring domain boundaries are respected and performance remains high. Take ownership of the development of new components and ideas as you cooperate with a multidisciplinary team to deliver end-to-end experiences to the End Users.
Lead Development: Write clean, high-performance code using Java 21+ features (Virtual Threads, Pattern Matching) to handle complex data transactions.
Search & AI Innovation: Work on the roadmap to integrate AI/LLM capabilities into our search engine ( Sinequa ), enabling users to explore data assets via natural language and intelligent discovery.
Data Stewardship: Oversee the polyglot persistence layer, optimizing PostgreSQL for relational integrity and MongoDB for flexible metadata storage.
Cloud Leadership: Design and maintain scalable infrastructure within AWS , ensuring our CI/CD pipelines and deployment strategies are best-in-class.
Mentorship: Act as a force-multiplier for the team, conducting rigorous code reviews and setting the standard for technical excellence.
Requirements
Technical Requirements
Strong experience with modern Java (21+) and Spring Boot 3.x
Hands-on experience with messaging technologies, ideally Solace
Good understanding of SPA architecture and frontend development with Angular and TypeScript
Familiarity with integration patterns and enterprise networking
Solid architectural knowledge, including modular monoliths, microservices, Data Mesh, and Domain-Driven Design
Experience working with PostgreSQL, MongoDB, and search platforms such as Sinequa
Practical experience with AWS services, including EC2, RDS, Lambda, and EKS
Experience with Infrastructure as Code, preferably Terraform
Who You Are
A Technical Visionary: You don't just solve today's bugs; you anticipate where the architecture will break two years from now.
Data-Centric: You understand that in a Data Mesh, the product is the data itself. You care about metadata, lineage, and discoverability.
User-Centered: You care about the end users experience and can cooperate with UX and Frontend developers to map and deliver first-in-class solutions.
Pragmatic Architect: You know when to stick with a monolith for speed and exactly when the "swell" justifies a move to microservices.
AI Curious: You are excited about moving beyond keyword search into the realm of semantic search and AI-driven data exploration.
The Roadmap: What You’ll Build
Phase 1: Refine the modular boundaries of the current Java 21 application. Deliver scalable and extensible transaction modules enabling Request-to-Use processes within the DataMarketPlace
Phase 2: Orchestrate the "Great Migration"—consolidate existing Marketplace ecosystems into DataMarketPlace on-boarding tens of thousands of assets and thousands of users.
