Software Development Engineer, AWS Lambda EDA

Job description

AWS Lambda (https://aws.amazon.com/lambda) is changing the way we think about computing in the cloud. Serverless computing offers customers an exciting new way to create applications, turn business logic and application code into scalable, fault-tolerant production systems without requiring them to be experts in distributed systems, deployment technologies, and infrastructure management.

We are part of AWS Lambda team who is making it easier for developers to build new applications or extend existing systems using serverless technology, by seamlessly integrating services such as DynamoDB, Kinesis, S3, Kafka, ActiveMQ and SQS as "Lambda Event Sources". Our growing team in Seattle has an opening for an experienced engineer who can help us to bring better experience to customers for building data driven applications.

Key job responsibilities

Design, develop, and maintain distributed systems that power AWS Lambda's event-driven architecture — connecting Lambda to streaming and messaging services like Kafka, SQS, DynamoDB Streams, and Kinesis

Build and improve scalable, multi-tenant platforms that process billions of events daily for millions of AWS customers

Write clean, well-tested code with high operational standards — you'll own what you build, from design through deployment and production operations

Drive features end-to-end

define technical approach, navigate cross-team dependencies, and deliver with high quality from design through multi-region rollout

Identify and solve ambiguous problems — propose solutions, evaluate tradeoffs, and make sound technical decisions with increasing independence

Participate in on-call rotations, lead operational reviews, and raise the bar on production reliability for your team's services

Contribute to system design, mentor junior engineers, and influence team best practices through code reviews and design discussions

Work across the full development lifecycle

requirements, design, implementation, testing, deployment, and monitoring

A day in the life

Morning

you check dashboards for your team's services — systems processing millions of customer events in real time. An alarm fires; you investigate, find the root cause, roll back, and update the runbook.

Mid-morning

you write code — a new feature that improves how the system scales under load. You push a code review and get sharp feedback from a senior engineer that makes the design better.

Afternoon

you join a cross-team design discussion, review a teammate's code (catching a subtle bug), and deploy your own change across multiple regions.

Your code runs infrastructure millions of developers depend on. You own real problems end-to-end, work with experienced mentors, and grow fast. No two days are the same.

About the team

We're a high-impact team within AWS Lambda responsible for event-driven architecture — the systems that connect Lambda to streaming and messaging services like Kafka, SQS, Kinesis, and DynamoDB Streams. Our platform processes billions of events daily for millions of customers worldwide. We value ownership, mentorship, and shipping quality software. Engineers here have real autonomy — you'll own features end-to-end and see your work matter at scale.

We support each other's growth, invest in operational excellence, and believe the best ideas can come from anyone on the team.
