Senior Software Engineer, Programming Foundations, ASBX

Are you a seasoned software engineer who thinks deeply about what it means to ship high quality code with confidence: not just your own code, but code written by AI, across the whole company? Amazon Software Builder Experience (ASBX) is hiring for a unique role: you'll be joining the team that owns Amazon's core testing platforms, and have a voice in setting the direction for AI-native software development at scale. You'll make a direct impact: helping create the future of human-guided, self-validating agentic coding for tens of thousands of world-class software engineers at Amazon. You will partner with your manager and leadership, and be a senior hands-on engineer in a dedicated team., You will play a key role on a team as it designs, builds, ships, and operates testing platforms and AI-driven testing capabilities, by:

• Being a clear technical leader, working in partnership with your colleagues to deliver architectures that scale with the needs of the business;

• Quickly and reliably delivering high-quality technical solutions that delight our customers;

• Building and operating distributed systems at global scale - serverless test orchestration, on-demand execution across every AWS region, and load testing platforms processing millions of transactions per day;

• Demonstrating excellent taste in developer experience and tooling design through the SDLC;

• Partnering with your manager and leadership to influence business strategy and product roadmaps;

• Meeting with customers to learn and help them shape their own testing story;

• Setting a high bar of technical and operational excellence, and empowering your colleagues to continuously meet and raise the bar.

As a senior engineer, you are a force multiplier to your teammates as much as you are a developer. This role will be a great fit if you have both passion and experience balancing coding, technical leadership, and communicating. You relish setting a positive example for less-senior engineers on craftsmanship, commitment to achieving customer outcomes and operational excellence, communicating clearly and with respect; and being deeply curious and confidently humble.

A day in the life Your customers are the tens of thousands of software engineers across Amazon, who are building AWS, Amazon.com, Alexa, and more. You'll be a lead hands-on engineer, building and operating systems at extraordinary scale: test platforms that are in the critical path of every deployment at Amazon, and AI capabilities already in daily use by tens of thousands of builders. You will partner with ASBX leadership and your customers, and guide and empower your colleagues to sustainably deliver high-quality customer outcomes.
