• Excellent troubleshooting and problem-solving skills across distributed systems.
• Track record of improving developer productivity through automation and platform reliability.

Desirable

• Experience applying DORA metrics to guide platform improvement.
• Knowledge of AWS cost optimisation and the Well-Architected Framework.
