Job Opportunity

BHSI is modernizing its data ecosystem, moving from a monolithic, reporting-centric infrastructure to a Lakehouse platform that supports insight-driven decisions and AI-enabled outcomes at the speed of business. We are seeking a Principal Data Architect to set the technical direction for that platform. You will own the architecture of our Databricks-based Lakehouse across data engineering, analytics, and AI/ML, ensuring it is secure, performant, cost-efficient, and ready for Generative AI.

You will report to the Global Head of Data Analytics Solutions and partner with Enterprise Technology portfolio leaders and business stakeholders.

Responsibilities

• Platform Architecture & Strategy: Define and evolve the enterprise Lakehouse reference architecture on Databricks, supporting batch, streaming, and AI workloads at scale across AWS or Azure.
• AI & Generative AI Enablement: Lead the design and rollout of Databricks AI capabilities, including vector search, model serving, and LLM orchestration, so teams can build, fine‑tune, and deploy models securely against enterprise data.
• Governance & Security by Design: Implement lineage, access controls, and auditing with Unity Catalog to meet regulatory requirements and ensure data quality across domains.
• MLOps & Engineering Excellence: Establish CI/CD and infrastructure‑as‑code standards for data pipelines and ML models. Optimize Spark performance, cluster configuration, and compute spend.
• Technical Leadership & Influence: Set architecture standards, run design reviews, and mentor engineers and data scientists. Translate business strategy into a phased technical roadmap and build alignment with engineering and business leaders.

Qualifications, Skills And Experience

• 15+ years in data engineering, data architecture, or software architecture, including 5+ years architecting on the Databricks Lakehouse Platform
• Deep expertise in Apache Spark, Delta Lake, Unity Catalog, and MLflow
• Proven experience designing infrastructure for both traditional ML and Generative AI workloads (RAG, fine‑tuning, vector search, agentic frameworks)
• Strong proficiency in Python and SQL, infrastructure‑as‑code (e.g., Terraform), and software design patterns
• Hands‑on architecture experience on AWS or Microsoft Azure
• Demonstrated ability to influence senior technical and business stakeholders without direct authority

Preferred Qualifications

• Databricks Professional or Expert‑level certification
• Experience with advanced agentic architectures, DSPy, or graph databases
• Background in insurance, financial services, fintech, or other regulated environments
• Track record of optimizing cloud compute costs while improving pipeline throughput

BHSI Offers

• A competitive package and exciting growth opportunities for career‑oriented teammates
• A dynamic, action‑oriented, and thoughtful environment centered on always doing the right thing for our customers, teammates and our other stakeholders
• A purposely non‑bureaucratic organization that embraces simplicity over complexity and emphasizes individual excellence in a team framework
• Benefits that support your life and well‑being, which include:
• Comprehensive Health, Dental and Vision benefits
• Disability Insurance (both short‑term and long‑term)
