Sigma Computing is hiring a Software Engineer - Compiler

Sigma Computing is redefining business intelligence by making complex data analysis accessible through a high-performance platform built for the modern data stack. The Compiler Team plays a foundational role in this mission by transforming user-driven spreadsheet interactions into highly optimized SQL queries, enabling seamless exploratory analytics on cloud data warehouses. As a member of the Compiler Team, you will join a group of engineers dedicated to building the core systems and abstractions that power Sigma’s intuitive spreadsheet interface, ensuring speed, reliability, and scalability for all users. What You Will Be Doing - Tackle core challenges at the intersection of data modeling, query compilation, and large-scale interactive analytics—making it possible for end-users to query data warehouses efficiently without deep technical knowledge - Design, build, and maintain sophisticated compiler infrastructure and intermediate representations that translate spreadsheet operations into optimized query plans - Apply advanced optimization strategies to improve performance and accuracy across a wide range of query workloads and data architectures - Contribute to both backend (Rust) and key frontend foundations (TypeScript), evolving critical abstractions that enable end-to-end workflow optimizations and new features - Debug, analyze, and resolve complex issues, ensuring robustness and maintainability in a rapidly evolving product - Collaborate with engineers and product stakeholders to review designs and code, driving technical best practices and architectural decisions throughout the team and company Qualifications We Need - 5+ years experience engineering high-quality software systems - Demonstrated success building and maintaining complex infrastructure or core platform services - Deep understanding of Computer Science fundamentals, particularly in compilers, algorithms, SQL Optimization - Passion for teamwork, technical ownership, and continually raising the engineering bar - Experience working in an iterative, high-cadence environment Qualifications We Want (also, skills you’ll learn!) - Exposure to distributed systems, query optimization, or database internals - Experience with API or data model design in the context of high-performance cloud services - Familiarity with cloud infrastructure (e.g., GCP, AWS, Azure) - A curiosity for new languages and tools, and a drive to solve challenging problems at scale (Rust, Go, Node, K8s, GraphQL)
