USD 70,000–100,000 per year, depending on experience and location About Fulcrum SaaS Fulcrum SaaS is a conversion rate optimization (CRO) platform that powers product recommendations for ecommerce brands. Our infrastructure processes high-volume behavioral events, feeds real-time recommendation algorithms, and serves personalized experiences at scale. We operate in a multi-tenant SaaS environment where data correctness, low latency, and system reliability are non-negotiable. Our stack includes Go, Bigtable, BigQuery, Pub/Sub, and a dual-store architecture (operational + analytical) that we designed from scratch. The Role We are looking for a senior backend engineer who has built and operated production data systems under real load—not prototypes, not internal tools. This is a core infrastructure role at the intersection of our operational and analytical data layers. You will own the systems that move behavioral event data from ingestion through transformation into our recommendation engine. You will design for correctness, build for observability, and make architectural tradeoffs with the pragmatism that only comes from production scars. You will be an early engineering hire with real influence over our technical direction. What You’ll Do Design and operate high-throughput event ingestion pipelines capable of processing millions of events per day with low-latency serving requirements. Own the dual-store architecture that separates our operational (real-time) and analytical (batch) data layers, including streaming vs. batch pipeline design and failure recovery.
