We’re looking for a Staff Software Engineer to join our Data Governance and Foundations Team. In this role, you’ll serve as a senior technical leader owning the architecture and delivery of our open lakehouse foundation, governance and access patterns, and multi-engine compute strategy—balancing today’s reliability with the next three to five years of scale, maturity, and cost efficiency. You’ll collaborate closely with engineering leadership and stakeholders across Data Science, ML Platform, Ads Infrastructure, Finance Engineering, Product Engineering, and Security. You’ll operate with a high degree of ownership in a fast-paced environment where architectural decisions have real technical and financial consequences.

ABOUT YOU MINIMUM QUALIFICATIONS * 10+ years of software engineering experience building and operating data infrastructure or distributed systems at production scale. * Hands-on expertise with modern data lakehouse architectures and open table formats (e.g., Apache Iceberg, Delta Lake, Hudi) and with distributed query/compute engines (e.g., Trino, Spark, ClickHouse), including performance tuning and production reliability. * Experience with event-driven and streaming infrastructure (e.g., Kafka, Flink) for real-time pipelines and serving systems. * Proven ownership of major platform transitions or migrations (build vs. buy, migration design, risk management) delivered to production. * Ability to build cost/benefit and TCO models for infrastructure investments and to drive alignment via clear architecture docs and strategy memos across multiple teams and leadership levels. PREFERRED QUALIFICATIONS * Experience designing platform-level governance controls and familiarity with compliance frameworks (e.g., SOX, CPRA, GDPR). * FinOps experience optimizing data platform spend, including managing multi-million dollar infrastructure budgets and negotiating vendor contracts. * Deep SQL proficiency and strong skills in Python or Scala for systems-level development. * Experience with orchestration (e.g., Apache Airflow) and data transformation pipelines (e.g., dbt) in large-scale production environments. * Bachelor’s, Master’s, or PhD in Computer Science, Computer Engineering, Electrical Engineering, or equivalent practical experience. #LI-Remote   Instacart provides highly market-competitive compensation and benefits in each location where our employees work.
