Senior Technical Expert Java

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.
