- Develop Foundry’s Iceberg catalog and engine integrations, including metadata, transactions, reads, and writes.
- Build shared transformation semantics and execution interfaces across products and platform services.
- Improve incremental processing so pipelines can reuse prior results while preserving correctness.
- Evaluate and integrate open-source data-system advances against real-world workloads.
- Investigate correctness and performance issues and build regression-prevention tests and benchmarks.
- Collaborate with product teams and customers to translate operational needs into engine capabilities.
Requirements
- At least 4 years of professional software engineering experience building and operating production systems.
- Engineering background in Computer Science, Mathematics, Software Engineering, Physics, or a similar field, or equivalent practical experience.
