Senior Technical Expert Java

Description

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

• 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.

Architectural Evolution:

• Write clean, high-performance code using features (Virtual Threads, Pattern Matching) to handle complex data transactions.

Lead Development:

• Java 21+
• Work on the roadmap to integrate into our search engine (), enabling users to explore data assets via natural language and intelligent discovery.

Search & AI Innovation:

• AI/LLM capabilities
• Sinequa

Data Stewardship:

• PostgreSQL
• MongoDB

Cloud Leadership:

• Design and maintain scalable infrastructure within , 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

• You don't just solve today's bugs; you anticipate where the architecture will break two years from now.

A Technical Visionary:

• You understand that in a Data Mesh, the product is the data itself. You care about metadata, lineage, and discoverability.

Data-Centric:

• You care about the end users experience and can cooperate with UX and Frontend developers to map and deliver first-in-class solutions.

User-Centered:

• You know when to stick with a monolith for speed and exactly when the "swell" justifies a move to microservices.

Pragmatic Architect:

• You are excited about moving
