Senior Data & AI Platform Engineer

As a Senior Data and AI Platform Engineer at Workiva, you will be a key hands-on engineer driving the build, operation, security, and optimization of our Enterprise Data Platform. You will implement and maintain account-level infrastructure—including Snowflake warehouses, RBAC permission models, data replication, dbt Mesh frameworks, and automated platform guardrails. Working as part of the Data & Analytics (DnA) function under the CIO, you will translate architectural strategy into scalable, reliable platform components that enable domain teams to build and operate safely.

In this role, you will help build and operate the data foundation for AI applications and agentic workflows, including Model Context Protocol (MCP) servers and evaluation pipelines. You will collaborate closely with Data Engineering, Analytics Engineering, AI/ML Platform, Security, and Governance (GRC) teams to implement robust data controls, enterprise cataloging (Atlan), and cost attribution frameworks.

You will report to the Sr. Director of Enterprise Data Platform, as part of the Data & Analytics function (DnA) under the CIO.

What You'll Do

Platform Engineering & Operations

• Build and maintain Snowflake platform infrastructure: Configure and operate warehouses, resource monitors, query tags, replication, account parameters, and advanced features (such as Iceberg, External Access Integration, and compute pools).

• Implement data mesh boundaries: Build and support dbt Mesh patterns and domain boundaries across business functions (Finance, Marketing Ops, CPX, etc.).

• Manage access & security models: Maintain RBAC permission models, service-user provisioning, solution-owner access patterns, and least-privilege enforcement in partnership with Okta and App Cafe.

• Maintain core data stack integrations: Operate and optimize integration patterns for orchestration (Airflow), ingestion (Fivetran), operational tools (Workato, Salesforce), and ELT workflows within established guardrails.

• Set and enforce operational standards: Drive best practices for naming conventions, schema/database layouts, environment promotion patterns, and code reviews across data teams.

AI & Agentic Data Infrastructure

• Build AI-ready data infrastructure: Implement Snowflake data access patterns for LLM pipelines, semi-structured data consumption, context retrieval, and feature store integrations in partnership with AI/ML teams.

• Operate MCP server infrastructure: Deploy and manage Model Context Protocol (MCP) servers that safely expose governed Snowflake data to AI agents and LLM applications.

• Execute agent testing & evaluation: Maintain evaluation pipelines and test suites to validate agent accuracy, detect hallucination risks, and verify data domain coverage before production release.

Security, Governance & Cost Management

• Implement compliance & privacy controls: Partner with GRC and Security to execute FedRAMP boundary controls, field-level masking, data sanitization, and schema security reviews.

• Cataloging & metadata management: Operate and integrate Atlan for enterprise data cataloging, column-level lineage, and lakehouse metadata governance.

• Optimize performance & cost efficiency: Drive cost visibility using query tags, warehouse sizing optimizations, and showback alignment with business departments.

Enablement & Team Collaboration

• Support multi-model data consumption: Enable BI tools (QuickSight, Sigma, Tableau, etc.), analyst personas, and developer workflows through performance tuning and access guidance.

• Peer mentorship & quality: Participate in design reviews, conduct pull request reviews, and mentor mid-level/junior engineers on data platform standards and dbt patterns.
