- A Tech Lead who is good at customer-facing interactions, willing to dive into business requirements, create a technical backlog, and lead three or four less experienced engineers.
Key Responsibilities
- Client & Stakeholder Engagement: Act as the primary technical point of contact for business stakeholders. Lead discovery workshops, unpack business requirements, and manage change expectations across teams.

Translate high-level business goals into structured epics, user stories, and actionable technical tasks; manage the team's sprint backlog.
- Team Leadership & Mentorship: Lead and mentor a team of 3-4 engineers through code reviews, technical guidance, and pair programming to elevate overall delivery quality.
- Hands-on Execution: Step into the code/pipelines when needed to unblock engineers, validate technical designs, and establish best practices for data modeling and transformation.
Technical Requirements Required Experience & Qualifications:
- Data Warehousing: Proven hands-on experience migrating legacy data platforms (specifically Amazon Redshift) to modern cloud warehouses (Snowflake).
- Data Governance & Retention: Expertise in designing schema architectures, partition strategies, and automated data retention/archival policies for regulatory compliance.
- Data Engineering & Pipeline Design: Proficiency in SQL, Python, and modern data stack tools (e.g., dbt, Airflow, or similar orchestration platforms).
- Leadership & Delivery Requirements
- Cross-Functional Background: Strong dual capability across technical solution design and product/business analysis (backlog grooming, requirements gathering, stakeholder alignment).
- People Leadership: Demonstrated experience mentoring and guiding early-career/mid-level data engineers.
- Communication & Change Management: Excellent customer-facing skills with the ability to articulate complex technical decisions to non-technical business leaders.
