• Owning code from idea through deployment and operation, including AWS design, security, and observability.
• Mentoring colleagues, conducting code reviews, and supporting a culture of learning and improvement.

Candidate Profile / Qualifications

• Significant experience in modern Java development (Spring Boot, Kotlin, or similar).
• Strong track record in designing and evolving scalable, Cloud-based systems.
• Practical experience with iterative development, automated testing, and CI/CD.
• A pragmatic and collaborative approach, with the ability to balance short-term needs and long-term goals.
• Excellent communication skills, with a passion for teamwork, knowledge sharing, and continuous learning.
