Job Summary
Ever wonder what happens when S3 processes a PUT request when DynamoDB commits a write with single-digit millisecond latency or when Kinesis Data Streams ingests a new record Behind the scenes a distributed log service is making it all possible and youd be building it.
The Transactional Services organization builds foundational distributed systems that power the largest AWS services. We specialize in high-performance strongly consistent data systems that operate at massive scale. Our systems process over 4 million writes per second today and are growing fast. When we ship the blast radius is AWS itself. Getting it right matters. Our customers depend on every write being durable and every read being consistent.
We have a multi-year roadmap packed with hard unsolved problems: pushing tail latencies lower than todays already tight targets continuously driving down the cost structure of the platform partnering with customers to deliver new capabilities and pushing the boundaries of durability availability and performance in distributed log systems. These are not small improvements. This is the work that shapes the foundation of AWS storage infrastructure.
As an SDE-II youll own systems end-to-end: from requirements and design through implementation deployment and production support. Youll dig deep into systems internals reasoning about memory layouts cache behavior lock-free data structures and network protocol design. The service is built primarily in Java with Rust used for the most performance-critical components high-consistency disk and networking IO where every microsecond counts. Youll troubleshoot complex production issues spanning multiple distributed components where the root cause is rarely obvious. Youll work alongside multiple Senior and Principal Engineers on a tight-knit team that values pairing co-ownership and direct collaboration. Youll also mentor junior engineers and help raise the teams technical bar through design reviews and engineering best practices.
This role demands strong computer science fundamentals. You should be comfortable reasoning about algorithmic complexity concurrency primitives and the trade-offs inherent in distributed systems. If you have a sharp eye for detail a passion for getting to the root cause and want to go deep on distributed systems and database internals not just use them but build the ones that AWS depends on this is the role.
Key job responsibilities
- Design and build highly available low-latency distributed log and database systems that process millions of writes per second for AWSs most critical services.
- Own end-to-end delivery of software projects from requirements through design implementation deployment and production support.
- Troubleshoot and resolve complex issues in production distributed systems using systematic debugging performance profiling and deep analysis of system behavior under failure conditions.
- Design and implement efficient data structures and algorithms optimized for throughput latency and memory efficiency in performance-critical paths.
- Identify and execute opportunities to reduce system latency and optimize cost efficiency across the platform.
- Drive improvements to security reliability durability and performance across multiple foundational services.
- Lead and contribute to multi-year cross-team migration and integration efforts with high-profile partner teams.
- Mentor junior engineers through code reviews design discussions and pairing sessions.
- Establish and evolve engineering best practices and operational processes for the team.
