• API & Data Engineering: Solid hands-on experience developing REST and GraphQL APIs, along with working knowledge of relational (MySQL) and NoSQL (MongoDB) databases and complex query design.
• Cloud & Automation: Experience working in cloud environments (preferably GCP) and writing automated web tests using modern frameworks (Jest, Cypress, Selenium).
• Modern Architectures & Tools: Proven experience in Agile environments using Git, with an understanding of modern web architectures (micro-frontends, Webpack Module Federation, service workers).

Experience that would be great to have

• Communication & Collaboration: Excellent written, verbal, and interpersonal communication skills, with a track record of effective cross-functional teamwork.
• AI-Assisted Development: Proven experience leveraging AI software engineering tools (e.g., GitHub Copilot, IDE plugins, AI coding agents) to optimize workflows, accelerate debugging, and elevate overall developer velocity.
• Back-End development or light knowledge in Java, Spring Boot & Microservices.
