Responsibilities:

• Design, develop, test, and deliver core database features across query processing, storage, replication, and transactions in YugabyteDB
• Write high-quality C/C++ code (and other languages as needed) with strong automated test coverage; actively participate in design discussions and code reviews
• Troubleshoot and resolve correctness, stability, and performance issues across:
• Distributed query planning and execution
• Storage and transactional subsystems
• Improve database scalability and throughput as cluster sizes, data volumes, and transaction rates grow
• Identify and implement performance optimizations across the stack, including:
• Query plan optimization, batching, and parallelism
• Storage engine and replication efficiency
• End-to-end latency and throughput improvements
• Build and enhance core operational capabilities
• Contribute to the open-source YugabyteDB project, helping strengthen its distributed SQL capabilities and reliability
• Collaborate closely with cross-functional teams (query, storage, platform, cloud) to deliver cohesive, high-quality features
• Mentor junior engineers and contribute to best practices in distributed systems, database internals, and performance engineering

Requirements:

• 5–8 years of software engineering experience
• Bachelor's or Master's in Computer Science (or related field), or equivalent practical experience
• Strong programming skills in C/C++ (or similar systems language)
• Solid understanding of: Data structures and algorithms, Operating systems fundamentals, Distributed systems basics
• Experience in at least one of: Database internals (query processing, execution engines), Storage systems (LSM trees, WAL, compaction, etc.), Distributed systems (replication, consensus, transactions)
• Strong problem-solving and debugging skills
• Hands-on experience building or working with distributed systems, including distributed storage, transactional engines, or consensus protocols
• Strong understanding of database internals, with familiarity in areas such as: PostgreSQL or other relational database engines, Query processing or storage engine design
• Contributions to open-source systems or database projects are a strong plus
