  • Explore and integrate other relevant GCP technologies (e.g., GKE, Cloud Functions, Pub/Sub) and implement security, access control, and compliance
  • Collaborate with product owners, analysts, and engineering teams to align solutions with business requirements
  • Actively participate in agile ceremonies and foster team collaboration
  • Support data needs for BI tools (Qlik Sense, Tableau, Looker). 
  • Apply strong understanding of banking/financial sector data, regulations, and reporting for compliance.
