Ever wonder what happens when
S3 processes a PUT request, when
EC2 launches a new instance, 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 you'd 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 scale. Our systems process over 4 million writes per second today and are growing fast. When we ship, the blast radius is
AWS itself.
We have a multi-year roadmap packed with hard, unsolved problems: building next-generation data export services, driving large-scale migrations that will reshape Amazon's storage infrastructure, and pushing the boundaries of durability, availability, and performance in distributed log systems. This isn't incremental work — it's foundational.
As an SDE-II, you'll own systems end-to-end: from requirements and design through implementation, deployment, and production support. You'll work alongside multiple Senior and Principal Engineers on a tight-knit team of 12 that values pairing, co-ownership, and direct collaboration. You'll also mentor junior engineers and help raise the team's technical bar through design reviews and engineering best practices.
If you 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
AWS's most critical services.
- Own end-to-end delivery of software projects — from requirements through design, implementation, deployment, and production support.
- 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.
- 3+ years of non-internship professional software development experience
- 2+ years of non-internship design or architecture (design patterns, reliability and scaling) of new and existing systems experience
- Experience programming with at least one software programming language
- 3+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
- Experience contributing to the architecture and design (architecture, design patterns, reliability and scaling) of new and current systems
- Experience debugging, profiling, and implementing best software engineering practices in large-scale systems
