• Demonstrable interest in software development (e.g., coursework, personal projects, bootcamp, career change portfolio) with a desire to specialise in C#/.NET and TypeScript.
• Comfortable with data and queries (basic‑to‑intermediate SQL is a plus) and keen to learn production diagnostics.
• A calm, methodical approach to troubleshooting and a willingness to follow runbooks, ask good questions, and escalare appropriately.
• Strong communication skills and the ability to explain what you are doing and what you have tried to both technical and non‑technical audiences.
• Willingness to use modern developer tooling responsibly to accelerate learning and delivery.
