• Demonstrated ability to perform critical-situation troubleshooting across complex, high-traffic backend environments.

• Practical knowledge of DevOps tooling, including GitHub, uDeploy, and SonarQube, with experience integrating these into an Agile development lifecycle.

• Working knowledge of SQL and the ability to apply it effectively in application analysis, tuning, and performance measurement.

• Proven ability to lead technical delivery, manage competing priorities, and operate with professional maturity across all levels of an organization.

• Bachelor's degree in a relevant field, or equivalent practical experience.

Beneficial Skills & Qualifications

• Experience with containerization technologies such as Docker and OpenShift.

• Familiarity with critical-incident diagnostic tools including Samurai, Thread Dump Analyser (TDA), or Memory Analyser Tool (MAT).
