The catalog provides a governed entry point for Iceberg tables and federated data sources across object stores,databases, data warehouses, and other lakehouse catalogs.As a Senior Software Engineer, you will own features from design through production. You will work on catalog services, metadata APIs, security, multi-tenant isolation, and integrations with Dremio and external query engines.This role suits an engineer who enjoys distributed systems, open standards, and software that must remain correct under concurrency and at scale.You will own changes from requirements through release and production support. After writing the specification and choosing an approach, you may use AI coding agents to help with implementation. You will review their work and validate its behavior, with particular attention to concurrency, authorization, compatibility, and failure handling. Changes that belong in Apache Polaris may also be contributed upstream. What youʼll be doing • Own multiple features within the Catalog team, from requirements and technical design through implementation, testing, rollout, and production support. • Extend Apache Polaris while preserving compatibility with the Iceberg REST Catalog specification. • Build catalog APIs and services for namespaces, tables, views, identities, permissions, and metadata operations. • Solve distributed systems problems involving consistency, concurrency, failure recovery, multi-tenancy, and service performance. • Diagnose production issues using logs, metrics, traces, and service data, then address the underlying cause. • Write design documents for the features you own and review designs from other engineers. • Work with query engine, security, platform, and product teams to define interfaces and manage dependencies. • Improve test coverage, operational tooling, and engineering practices in the areas you touch. • Review code with attention to correctness, security, maintainability, and performance. • Share technical knowledge with the team and help onboard or mentor newer engineers. • Contribute fixes and features upstream when they belong in Apache Polaris or another open-source project. • Use AI-assisted development tools for code comprehension, debugging, and test generation, while verifying their output through engineering review and testing. What weʼre looking for • Five or more years of professional software development experience, or equivalent practical experience. • Strong Java skills and experience with a substantial production codebase, supported by knowledge of data structures, algorithms, concurrency, API design, and distributed systems. • A record of owning backend or distributed-system features from design through rollout and production support, including estimating work and managing dependencies. • Ability to turn incomplete product requirements into implementation-ready specifications covering interfaces, invariants, failure cases, security, and acceptance criteria. • Experience directing AI coding agents, reviewing their plans and output, and correcting unsafe or unsuitable approaches. You remain accountable for every change you own, regardless of how the code was produced. • Strong code-review judgment, particularly around concurrency, authorization, compatibility, performance, and maintainability. • Experience validating changes through automated tests, static analysis, and production telemetry, then using that evidence to diagnose failures and address their root causes. • Clear written and verbal communication in specifications, design documents, technical discussions, and code reviews. • A bachelorʼs degree in Computer Science or a related field, or equivalent practical experience. Bonus points if you have • Experience with Apache Polaris, Apache Iceberg, or the Iceberg REST Catalog specification. • Knowledge of metadata catalogs, authorization systems, credential vending, or policy enforcement. • Experience building multi-tenant cloud services. • Familiarity with databases, transaction isolation, and consistency models. • Experience with Kubernetes and public cloud infrastructure. • Familiarity with Apache Spark, Apache Flink, Trino, or other engines that integrate with Iceberg catalogs. • Contributions to Apache or other open-source projects What we value At Dremio, we hold ourselves to high standards when it comes to People, Thinking, and Action.
