• Degree in Computer Science, Engineering, or a related field (or equivalent proven experience).
• English proficiency at B2 level or above, with the ability to articulate complex technical concepts to diverse stakeholders.
• A strong sense of ownership over your work and a commitment to continuous learning and knowledge sharing.

• Architect and develop scalable, high-quality cloud services, ensuring they meet the demands of a global client base.
• Master Domain-Driven Design (DDD) principles to build modular, maintainable, and highly performant software components.
• Drive AI Integration with use of AI tools (e.g., GitHub Copilot, LLM-based assistants) to automate code generation, refactoring, documentation, and unit testing.
• Design RESTful Web Services that facilitate seamless communication within our complex cloud infrastructure.
• Optimize Azure Services to ensure our infrastructure is not only performant and scalable but also cost-effective and secure.
• Collaborate within cross-functional teams of engineers, product owners, and designers, fostering a culture of mutual support and accountability in an agile environment.
• Champion code excellence by implementing best practices in code testing, maintaining quality standards, and providing insightful code reviews.
