Senior Software Engineer, AWS Applied AI Solutions
Posted Updated
As part of the AWS Applied AI Solutions organization, we have a vision to provide business applications, leveraging Amazon’s unique experience and expertise, that are used by millions of companies worldwide to manage day-to-day operations. We will accomplish this by accelerating our customers’ businesses through delivery of intuitive and differentiated technology solutions that solve enduring business challenges. We blend vision with curiosity and Amazon’s real-world experience to build opinionated, turnkey solutions. Where customers prefer to buy over build, we become their trusted partner with solutions that are no-brainers to buy and easy to use.
We're building Chorus, a real-time document workspace where AI agents are actual collaborators: an agent gets a cursor in the doc, edits the same CRDT, and shows up in presence right next to you. We wrote it from scratch in Rust and TypeScript, we sync in under 50ms with hundreds of simultaneous editors on a single document, and it costs roughly a dollar per builder per year to run. It's an exciting combination of greenfield work with a massive user base that provides immediate feedback when something doesn't work.
We're a small team with an unusually direct line from idea to thousands of builders using it. If you want to be one of maybe a dozen people in the world shipping production CRDT infrastructure that treats AI as a peer, this is the job.
Key job responsibilities
* Own end-to-end technical architecture for a service that is scaling from early customers to AWS-wide adoption
* Work directly with internal and eventually external customers to understand integration needs, set expectations, and turn real-time feedback into service direction
* Drive technical consensus across partner teams with competing priorities and constraints
* Make judgment calls on when to solve a problem scrappily for one customer and when to build the abstraction that serves many
* Mentor and develop junior and mid-level engineers through code reviews and design reviews
* Drive operational excellence: define monitoring and alarming standards, ensure production readiness for new features, and build a culture where the team can sustain what it ships
* You own a problem space end to end, identify the most salient problems now and deliver solutions quickly without sacrificing long-term scalability
* Inventive usage of LLMs in software development. You find ways to deliver code with agents at high speed, but without sacrificing the quality of the code or the software.
* Deep experience in Rust or systems-level TypeScript, or the track record to show you'll get there fast. We care more about how you think about correctness under concurrency than which language you learned it in.
A day in the life
Your mornings are usually free for focus work - architecture, deep dives, and hard problems. Around 11 you'll have standup, then grab lunch with the team (if you like) before the afternoon opens up for design reviews, CR feedback, or unblocking an engineer. Some days you're deep in code; others you're on a call with a customer team working through how their system integrates with yours. You're the person who knows the system most deeply - and you work to ensure you're never the bottleneck. The problems are hard and the stakes are high - but we believe we can move fast, do exceptional work, and have a full life outside of it.
We're a small team building two greenfield projects within Agentic WorkSpaces. We're moving fast enough that our team name is still taking shape — but our engineering culture is well established.
About the team
ABOUT AWS:
Diverse Experiences
Amazon values diverse experiences. Even if you do not meet all of the preferred qualifications and skills listed in the job description, we encourage candidates to apply. If your career is just starting, hasn’t followed a traditional path, or includes alternative experiences, don’t let it stop you from applying.
Why AWS
Amazon Web Services (AWS) is the world’s most comprehensive and broadly adopted cloud platform. We pioneered cloud computing and never stopped innovating — that’s why customers from the most successful startups to Global 500 companies trust our robust suite of products and services to power their businesses.
Work/Life Balance
We value work-life harmony. Achieving success at work should never come at the expense of sacrifices at home, which is why flexible work hours and arrangements are part of our culture. When we feel supported in the workplace and at home, there’s nothing we can’t achieve in the cloud.
Inclusive Team Culture
Here at AWS, it’s in our nature to learn and be curious. Our employee-led affinity groups foster a culture of inclusion that empower us to be proud of our differences. Ongoing events and learning experiences, including our Conversations on Race and Ethnicity and AmazeCon conferences, inspire us to never stop embracing our uniqueness.
Mentorship and Career Growth
We’re continuously raising our performance bar as we strive to become Earth’s Best Employer. That’s why you’ll find endless knowledge-sharing, mentorship and other career-advancing resources here to help you develop into a better-rounded professional.
