Role PurposeThe Senior Data Platform Architect is responsible for the end‑to‑end architecture, security design, and governance of SSIM's enterprise data platform spanning Snowflake, Databricks, open data platforms (Iceberg/Parquet/Delta), and data virtualization. Requires previous experience supporting workloads in analytics, regulatory reporting, AI/ML, and batch applications.The person in this role will ensure the modern platform meets financial‑services regulatory expectations, enterprise security standards (GCS/IAM), and data protection requirements (NPPI/PII). They Will Enable scalable, interoperable delivery across Investment Management use cases.This role is hands‑on, decision‑critical, and risk‑bearing, with accountability for architectural choices that directly impact regulatory compliance, audit defensibility, and business continuity. Platform Designs must be Secure, Scalable, include Disaster Recovery, as well as Data Sharing capabilities. Design and Build monitoring as well as chargeback models for billing back to application teams.Core Responsibilities1. Data Platform Architecture & IntegrationDefine and govern the hybrid Snowflake–Databricks architecture to support classic Data Warehousing as well as Data Lake designs, aligning Snowflake's governed analytics layer with Databricks' engineering, streaming, and ML capabilitiesEstablish reference blueprints, patterns using lakehouse and medallion patterns suited for enterprise scale and auditability. Contribute Designs, Patterns, Assets to SSIM Center of Excellence which establishes Best Practices for each platform as well as use cases for Reuse.Lead Iceberg/Horizon/Unity Catalog interoperability across AWS, Azure, and GCP2. Open Platforms & Open Table FormatsArchitect open data platform strategy leveraging Apache Iceberg, Delta Lake, Parquet, and Polaris/Unity Catalog to avoid vendor lock‑in and enable cross‑engine queryDefine standards for open table format adoption, including:Business Tool Access Protocols, Drivers, StandardsNaming Standards, Folder Structures, Cloud Storage SecuritySchema evolution, partitioning, and time‑travelCross‑engine compatibility (Snowflake, Databricks, Trino, Spark, Athena)Catalog federation across Horizon, Unity, Glue, and PolarisEstablish governance for open formats in regulated workloads (lineage, access control, encryption)Drive interoperability between proprietary and open ecosystems to support modernization and exit strategiesCapture Feedback, Fialings, Suggestions form the Users an Provide that Distilled information back to Vendors to Improve their Offerings3. Data Virtualization & Federated AccessArchitect data virtualization patterns to enable logical access to data across Snowflake, Databricks, Oracle, SQL Server, and legacy NAS/file systems without physical movementDefine use cases for:Federated queries (Snowflake external tables, Databricks Lakehouse Federation, Trino/Starburst, Denodo)Virtual data products for analytics and reportingLogical data fabric spanning cloud and on‑prem sourcesEstablish guardrails for performance, cost, security, and data classification in virtualized access patternsReduce data duplication, copy proliferation, and storage cost through virtualization where appropriate4. Batch Application Solutioning & ModernizationLead architecture and solutioning for batch applications migrating from legacy platforms (Oracle, mainframe, Unix/Linux ETL, file‑based workflows) to Snowflake/DatabricksDefine patterns for:Batch ingestion and orchestration (Airflow, Databricks Workflows, Snowflake Tasks/Streams, Control‑M integration)Window/SLA‑driven batch processing with monitoring and rerun safetyMigration of legacy stored procedures, PL/SQL, and shell‑based ETL to cloud‑native equivalentsHybrid batch + streaming patterns (medallion, change data capture)Establish batch performance, cost, and resiliency standards, including Reprocessing, Transaction Rollback, Event Logging, Query Timeout Limits, Warehouse Credit Limits, Finding/Flagging Expensive Processes from Account Usage Tables.Partner with application owners to retire legacy infrastructure as part of data center exit and cloud migration programs. Previous Redshift, DB2, SQL Server experience is a help for migrating off of these platforms and data conversion issues that arise.Identify Out of Date Drivers and Application Versions that could be Security Risks, and Advise Applications Teams what to upgrade to, so teams modernize while migrating.5. Security, Governance & Regulatory AlignmentArchitect and enforce data security by design, including:Design RBAC Roles at a Group Level for R, RW, Admin at the DB, Schema, Object Levels. This should balance security needs with what is reasonable overhead to Administrate.Advise on Lower Level Row Access Policy, Column Masking, Secure Views so App Teams have row‑level and column‑level security where necessary.Familiar with Establishing Future GrantsKnowledge of Managed Access Schemas and trade offs.Knowledge of Network Address White Listing. Knowledge of Cloud Level Roles and Security Integrations and how they enable data access with Snowflake Horizon and Databricks Unity Catalog additional features.Ensure compliance with SOX, MRAs, internal/external audits, and data protection controlsMaintain defensible audit trails, lineage, and forensic traceabilityAlign with GCS data residency, isolation, and classification standards6. Multi‑Cloud Platform Engineering (AWS / Azure / GCP)Architect cloud‑native integrations across S3, ADLS, GCS, IAM, networking, and private link patternsDrive cross‑region/cross‑cloud HA/DR designs including Snowgrid replication and Iceberg federationEnsure vendor security, networking real‑time/streaming, and disaster recovery are embedded in design7.
