In this role, you will lead the engineering and operations for a major Customer 360 Data Lakehouse. You will sit on the client side, acting as the bridge between the Singapore business and our global delivery team. You are not just overseeing delivery; you are the Lead Data Architect responsible for the solution's integrity, stability, and evolution We need a leader who can manage executive client stakeholders to discuss Data Strategy with Group Heads, and then immediately sit with the engineering team to debug complex Kubernetes/Airflow ingestion issues or optimize Snowflake clustering keys Key Responsibilities 1) Platform Technical Architecture  (The Design) You are the Technical Design Authority for the account. You ensure the solution is architected for scale, performance, and future readiness. Solution Architecture: Own the roadmap for the C360 Data Lakehouse. You will drive the evolution of the data model, ensuring it supports advanced use cases like GenAI (Cortex)  and CDC streaming. Snowflake Engineering: Act as the Lead Snowflake Architect. You will personally oversee the optimization of micro-partitions, clustering keys, and virtual warehouse sizing to ensure high performance. Ingestion Modernization: Lead the architectural improvements of the Data Pipes ingestion layer. You will guide the engineering team on re-architecting DAGs in Apache Airflow and optimizing Kubernetes resource allocation. Technical Quality: Enforce a Zero-Defect mentality. You are responsible for the architectural review of all code before it reaches production. 2) Snowflake Platform Operations & Management (The Run) You serve as the ultimate Technical Authority for this account, ensuring the proposed solution is designed for maximum scale, optimal performance, and long-term viability.

Remediation: Apply fixes to SQL pipelines or coordinate with upstream teams. Use Zero-Copy Cloning to create safe sandbox environments for testing data fixes before applying them to production. False Positive Reduction: Continuously tune DQ thresholds (e.g., standard deviation variances) to minimize alert fatigue and ensure high-fidelity notifications. Experience in Snowflake Cortex: Will need to work with Snowflake Cortex for AI enabled search and agents to help diagnose issues 4) Process Engineering & Automation You champion efficiency by transforming manual operational tasks into automated, scalable processes. You are responsible for closing the loop between operations and architecture, ensuring that every incident drives systemic improvement and reduces future toil. Automate Operational Toil: Use Snowpark (Python) or Stored Procedures to automate repetitive maintenance tasks (e.g., archiving old tables, granting permissions, generating DQ reports). Incident Management Frameworks: Define and execute the playbook for Data Incidents. Ensure all data outages are logged with clear severity levels and post-mortem documentation. Feedback Loops: Create a feedback loop between the Operations team and Data Architects to ensure that frequent data issues are addressed at the architectural level. 5) Stakeholder & Client Engagement You serve as the bridge between technical complexity and business value. You cultivate trust by providing transparent visibility into data health and empowering business teams to understand, govern, and utilize their data assets effectively. Trust & Transparency: Publish regular Data Quality Reports (via Snowsight Dashboards or BI tools) to business stakeholders.
