Software Development Engineer, AWS DynamoDB

## Responsibilities - Design, build, and operate distributed infrastructure systems that provision, bootstrap, and manage the DynamoDB test cluster fleet. - Own systems end-to-end. Take a problem from design through implementation, deployment, and ongoing operation. No handoffs — you build it, you run it, you improve it based on production data. - Deliver independently with minimal guidance. Break down ambiguous problems into executable plans. Your manager sets direction; you figure out the how and drive to completion. - Debug complex distributed systems issues. Trace failures across multiple services, accounts, and regions. Identify root causes — not just symptoms — and fix them structurally. - Write production-quality code in Python and Java. Ship weekly. Maintain high standards for testing, monitoring, and operational readiness. - Operate the fleet on-call. Triage tickets, respond to alarms, and use what you learn operationally to drive reliability improvements back into the systems. - Collaborate across teams. Engage partner teams to unblock dependencies, review designs, and align on technical approaches. Communicate clearly in writing and in person. - Influence technical direction. Propose improvements, write design docs, and participate in architecture decisions. You're expected to have opinions backed by data and advocate for them. - Mentor junior engineers and interns. Review code, give constructive feedback, and help others grow. ## Requirements - Deeply technical, team-first software development engineer. - Experience with distributed systems, large-scale infrastructure, and cloud computing. - Strong background in Python and Java. - Ability to work independently and take ownership of complex projects. - Strong debugging and problem-solving skills. - Experience with AWS services such as DynamoDB, Lambda, Step Functions, CloudFormation, EC2, and IAM. - Experience with on-call operations and system reliability. - Strong communication and collaboration skills. - Ability to mentor and guide junior engineers. ## Nice to Have - Experience with AI coding tools. - Experience with cross-region networking and security boundaries. - Experience with fleet management and automation. - Experience with CI/CD pipelines and infrastructure as code. - Experience with large-scale distributed systems. ## Benefits - Work on the hardest engineering problems in distributed systems at a massive scale. - Opportunity to influence technical direction and architecture decisions. - Collaborate with motivated teams of sharp individuals. - Mentor junior engineers and interns. - Work on a small team with a large scope and real ownership. - Use cutting-edge technologies and tools. - Impact the velocity of hundreds of engineers through infrastructure improvements.
