Description

Join the Programming Foundations Team within Amazon Builder Experience as a Software Development Engineer. The Language Experience team in Builder Tools is the center of excellence for Amazon's use of programming languages, highly-leveraged shared software, and application build tools.

Our tools are used in all aspects of the business, and their care and evolution are of critical importance to the effectiveness of Amazon. We're looking for a deeply technical leader interested in sustaining and evolving the shared software platform used by nearly every service within the company. Those with experience evolving broadly distributed and highly complex software libraries, such as large open source projects and mission critical foundational software stacks will be given an opportunity to have company wide impact.
Amazon Builder Experience is a part of AWS Utility Computing (UC) which provides product innovations — from foundational services such as Amazon’s Simple Storage Service (S3) and Amazon Elastic Compute Cloud (EC2), to consistently released new product innovations that continue to set AWS’s services and features apart in the industry. As a member of the UC organization, you’ll support the development and management of Compute, Database, Storage, Internet of Things (Iot), Platform, and Productivity Apps services in AWS, including support for customers who require specialized security solutions for their cloud services.



Key job responsibilities
You will design and build developer tools that Amazon engineers use every day. You will work with the languages and libraries that power Amazon's services, making them easier to use and more reliable. You will help maintain our build tools, compilers and package managers. You will work on our 3PSW repository mirrors. You will collaborate with engineers across Amazon to understand their pain points and build tools that address them. You will write code, review code from teammates, and help others debug issues with our tools.

A day in the life
Your work will directly affect how builders at Amazon do their jobs. We are a language expertise team at the heart of being able to compile and shift software. This is practical work that requires understanding what builders actually need and building tools that solve their problems without getting in the way.

About the team
The Programming Foundations Team is part of Amazon Builder Experience. We work on the basic tools and infrastructure that builders use to write software. Our team includes engineers who care about developer experience and want to make building software at Amazon easier. We do not own customer-facing products directly, but our work affects every team that builds software at Amazon. We focus on doing useful work rather than flashy projects. If you like building tools that help other engineers and want to work on problems that span the whole company, this team might be a good fit.

Diverse Experiences
AWS 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.
Inclusive Team Culture
AWS values curiosity and connection. Our employee-led and company-sponsored affinity groups promote inclusion and empower our people to take pride in what makes us unique. Our inclusion events foster stronger, more collaborative teams. Our continual innovation is fueled by the bold ideas, fresh perspectives, and passionate voices our teams bring to everything we do.
Mentorship & 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.
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 we strive for flexibility as part of our working culture. When we feel supported in the workplace and at home, there’s nothing we can’t achieve.
