• Ensure high‑quality code through unit testing, automated testing, and adherence to best practices.
• Collaborate with cross‑functional teams (BAs, QA, PMs) to deliver solutions aligned with business requirements.
• Demonstrate T‑shaped skills, contributing across development areas and supporting team members in building their own breadth of expertise.
• Participate in Agile ceremonies and foster a culture of continuous improvement.

• Experience with back‑end programming languages (TypeScript and/or other OOP languages such as C# or Java).
• Experience with C# (.NET 8+) in a professional environment.
• Ability to work with BAs/POs to clarify requirements and constructively challenge assumptions.
• Experience in technical platform teams delivering reusable services across multiple projects.
