Demonstrated leadership and relationship-building skills, with a service-oriented approach to working in a fast-paced environment.
Strong working knowledge of SQL, applied to analyze data and resolve complex application issues.
Solid understanding of ETL processes, combined with hands-on Unix or shell scripting skills for application troubleshooting.
Working knowledge of Python and a clear understanding of microservices-based architecture.
Bachelor's degree in a relevant field, with availability to work occasional weekends during critical incidents, for which compensatory leave is provided.

A hybrid working model, with 3 days in the office and 2 days working remotely, to support work-life balance.
Opportunities to mentor junior analysts and build your leadership profile within a global technology team.
Access to learning and development programs that support long-term career growth.
Compensatory leave provided for any weekend work completed during critical incidents.
