Take direct ownership of high-complexity or high-risk engineering initiatives, from technical design through implementation and rollout.
Identify and resolve performance, scalability, and reliability bottlenecks across the existing data platform.
Contribute to the platform's AI/ML readiness by improving data models, governance, and access patterns (e.g., feature stores, curated datasets, streaming access).
Diagnose and resolve complex production issues, including on-call support for critical data pipeline failures.
Write clean, well-tested, well-documented code and infrastructure-as-code, and maintain strong engineering hygiene across your work.
Technical Leadership & Collaboration
Act as a senior technical resource for the team, providing guidance on architecture, design patterns, and best practices.
Conduct code and design reviews, helping raise the technical bar across the Data Engineering team.
Partner closely with the Director, Data Engineering on technical design decisions, tooling evaluations, and platform roadmap input.
Mentor other data engineers, sharing knowledge and helping develop their technical skills.
Partner cross-functionally with Product and Engineering stakeholders to understand data needs and translate them into technical solutions.
Help document standards, runbooks, and architectural decisions to support team scalability and knowledge sharing.
