Job Title: Senior Data Systems Architect & Analytics Lead
Role Overview
We are seeking a Senior Data Systems Architect & Analytics Lead to serve as the technical engine behind our cloud-based data lakehouse environment. This is a hands-on, high-complexity role for a data professional who thrives at the intersection of engineering and analytics. You will be responsible for building complex data models, performing deep-dive troubleshooting on integrated systems, and enforcing robust data governance and security protocols.
This role requires a "builder" mentality.

• BI & Data Visualization: Develop and performance-tune high-impact dashboards, ensuring that both operational and executive stakeholders have a "single source of truth" for their performance metrics.
Governance, Security & Strategy
• Data Security & Governance: Implement Role-Based and Attribute-Based Access Control (RBAC/ABAC) frameworks. Manage metadata and data lineage to ensure compliance, consistency, and traceability across the organization.
• Agile Leadership: Drive data product development within an Agile/SAFe framework. Manage backlogs, refine technical requirements, and facilitate cross-functional sprints.
• Stakeholder Enablement: Act as a technical consultant to the business. Facilitate training sessions, communicate complex data findings to non-technical audiences, and foster a "data-first" culture across virtual teams.
Qualifications & Requirements
Minimum Qualifications
• Education: Bachelor's degree in Computer Science, Data Analytics, Business, or equivalent experience.
• Experience Baseline: Extensive experience designing, deploying, and troubleshooting applications within a complex, cloud-hosted data lakehouse environment.
• Technical Mastery:
