- Improve automation, reliability, observability, and cost efficiency across our AWS-based ecosystem.
- Strengthen data governance, lineage, validation, and quality standards across the platform.
- Lead initiatives to modernize ingestion patterns, including expanding tools like Fivetran and improving workflow maintainability.
- Contribute directly to architecture, code reviews, and complex problem-solving across DBT, and warehouse layers.
- Own end-to-end data workflows from ingestion (Postgres and backend systems) through transformation and warehouse delivery.
- Partner cross-functionally to translate evolving business needs into scalable, production-grade data solutions.
- Mentor and develop engineers while fostering a culture of ownership, accountability, and technical excellence.
What We're Looking For:
- 8+ years of experience in data engineering, data warehousing, or data architecture roles.
- Experience leading or mentoring engineers on small to medium-sized teams.
- Strong experience working within AWS environments.
- Strong architectural judgment and experience building scalable, production-grade data platforms.
- Experience designing or evolving modern cloud data warehouse solutions.
- Strong understanding of distributed systems, data modeling, and ETL/ELT design patterns.
- Proven hands-on experience with AI tools (e.g., Cursor, ChatGPT, etc.) as a core part of daily workflows, driving productivity and enhancing output quality, alongside a commitment to continuously developing AI expertise
- Consistent integration of AI into workflows and decision-making, with strong judgment—validating outputs, adhering to Stash guidelines (especially for sensitive data), and owning the quality of AI-assisted work
- Experience improving platform reliability, performance, and cost efficiency.
- Excellent cross-functional communication skills.
- Ability to operate as both a people leader and hands-on technical contributor.
Gold Stars:
- Experience implementing or migrating to Snowflake.
- Working knowledge of DBT and analytics engineering best practices.
- Experience implementing automated ingestion tools such as Fivetran.
- Experience working in regulated environments (PCI, SOC 2, fintech).
- Startup or scale-up experience in fast-moving, high-growth organizations.
