About the Role

As a Senior/Principal Platform Engineer, you will serve as the technical authority for Harman's BI, AI, and Data platforms — owning both the architecture and hands-on development of scalable data pipelines, platform components, and infrastructure that enable reliable analytics and AI capabilities.

You will operate at the intersection of architecture and execution, personally designing and building complex SQL and Python-based data pipelines while setting the technical direction for the broader platform. You will define architectural patterns, drive engineering excellence, and remain deeply embedded in the codebase — writing production-grade code that sets the standard for the team.

This role requires exceptional technical depth, architectural vision, and the ability to lead through both design authority and hands-on contribution. You will shape platform strategy, drive cross-team alignment, and ensure the long-term scalability, reliability, and evolution of the data platform.

What You Will Do

1. Platform Architecture & Technical Authority

• Architectural Ownership: Define and own the end-to-end architecture of data pipelines, platform services, and infrastructure — making binding technical decisions on design, tooling, and patterns.

• Hands-On Development: Personally architect and build complex SQL and Python-based data pipelines, writing production-grade code that serves as the reference implementation for the team.

• Technical Vision: Set the long-term technical direction for the platform, evaluating emerging technologies and defining the roadmap for platform evolution.

2. Data Pipeline Development & Engineering Excellence

• Pipeline Architecture & Development: Design, architect, and personally build high-complexity data pipelines for ingestion, transformation, and processing at scale — using Python, PySpark, and SQL as primary development languages.

• SQL & Transformation Development: Author advanced SQL transformation logic, complex query patterns, and performant data models aligned with enterprise data architecture. Establish SQL development standards and reusable patterns for the team.

• Python & Framework Development: Build and maintain Python-based pipeline frameworks, utilities, and reusable components that accelerate team delivery and enforce consistency.

• Code Quality & Standards: Define and enforce coding standards for SQL and Python development across the team. Conduct deep code reviews and establish patterns for testability, maintainability, and performance.

• Performance Engineering: Lead root-cause analysis and resolution of complex pipeline failures, performance bottlenecks, and data inconsistencies — applying deep expertise in query optimization and distributed processing.

3. Data Platform & Infrastructure Engineering

• Data Architecture Ownership: Architect and enforce structured data layers (e.g., Bronze/Silver/Gold), defining schemas, data contracts, and quality gates that ensure scalability and governance.

• Integration Architecture & Development: Design and build complex integrations with internal and external data sources, including APIs, streaming pipelines, and event-driven architectures.

• Infrastructure as Code Leadership: Architect and implement Infrastructure as Code strategies using best-in-class tools, defining patterns and modules that enable repeatable, scalable provisioning.

• Environment Strategy: Own the strategy for environment consistency and reliability across Dev, QA, and Production — designing promotion workflows and environment parity standards.

4. Deployment, DevOps & Infrastructure as Code

• Release Strategy: Define and own the deployment strategy for data pipelines, infrastructure, and platform components across all environments.

• Infrastructure as Code Architecture: Architect enterprise-grade infrastructure provisioning using tools such as Terraform, Pulumi, or similar — defining module structures, state management, and governance patterns.

• Cloud & Platform Architecture: Drive architectural decisions across modern cloud platforms (AWS, Azure, Databricks), designing scalable, cost-effective, and secure data solutions.

• CI/CD Architecture: Architect end-to-end CI/CD pipelines for automated testing, validation, and deployment of both application code and infrastructure.

• Source Control & Engineering Practices: Define and enforce Git workflows, branching strategies, code review practices, and version control standards across the team.

5. Technical Leadership, Standards & Mentorship

• Engineering Leadership: Provide deep technical mentorship to Senior and Junior Platform Engineers — elevating team capabilities through pairing, design reviews, and hands-on guidance.

• Standards & Governance: Define and enforce coding standards, architectural guidelines, data governance policies, and engineering best practices across the platform.

• Cross-Team & Stakeholder Alignment: Partner with System Architects, Engineering Managers, and senior stakeholders to align platform implementation with enterprise strategy and business objectives.

• Documentation & Knowledge Sharing: Drive creation of architectural decision records, design documents, and comprehensive technical documentation that enables team autonomy.

6. AI-Assisted Development & Platform Evolution

• AI-Driven Engineering: Leverage and champion AI-assisted tools to accelerate development, debugging, testing, and documentation across the team.

• Platform Innovation: Identify and drive opportunities to improve platform efficiency through automation, reusable frameworks, and self-service capabilities.

• Continuous Improvement & Industry Leadership: Stay at the forefront of modern data platform, AI, and engineering trends — evaluating and introducing technologies that advance platform maturity.

What Success Looks Like
