Why this Role is Featured on The SaaS Jobs
Data engineering roles are increasingly central to SaaS products that rely on analytics as a feature, not just an internal function. This position stands out for its emphasis on production-grade ELT that supports reporting and core product capabilities, using a modern AWS-heavy approach. The mention of Medallion architecture signals a platform mindset common in maturing SaaS companies formalising how data moves from raw inputs to trusted, consumable layers.
For a long-term SaaS career, the work maps closely to problems that recur across subscription software businesses: reliability, observability, and data quality at scale. Building and operating workflows with services like Lambda and Step Functions develops practical skills in event-driven pipelines, cost-aware transformations, and maintainable data modeling. Collaboration with product and engineering also reinforces the cross-functional habits needed when data outputs influence customer-facing decisions.
