As an SDM in Amazon's Simple Storage Service (S3), you will solve exciting problems at incomparable scale. You will help build systems that manage trillions of objects in storage, retrieve them in milliseconds, across tens of thousands of hosts, all while maintaining 99.999999999% (you didn't read that wrong, that's 11 nines!) of data durability.

Amazon S3 powers businesses, nonprofits, and transformative organizations across the globe that make the lives of people better daily.

Key job responsibilities

• Innovating on lightweight processes to allow for quick iteration in a highly ambiguous space.
• Driving the day to day sprint work as well as roadmap for your area
• Collaborating with other engineering leaders to find solutions to brain-contorting problems
• Developing the careers of your people, actively mentoring them

A day in the life

• You will cultivate a culture of fast-paced innovation with lightweight processes.
• You will collaborate with product and partner with teams within AWS to deliver product features.
• The services you will own and build are the foundation of S3 and you will tackle some of the most difficult problems in S3 head-on.
• In AWS, if you build it, you own it.
• This means we hold a high bar for test automation, verification, design, and code reviews to ensure our systems meet high standards we demand in service of our customers.

Our team puts high value on work/life balance. We recognize that the circumstances of our team members vary, and we balance work across the team so that we're all able to maintain high standards on behalf of our customers, as well as allow for rich and happy personal lives. We maintain a regular on-call rotation across our teams with engineers and managers all taking part to resolve the inevitable issues that arise.

We don't like getting paged outside of work hours so we work to ensure our systems are fault tolerant. When we do get paged we work together to resolve root cause so that we don't get paged for the same issue twice.

Upon joining S3, every employee is paired with a peer buddy who will help you to quickly come up to speed in understanding the technology we're building, the tools we use and the business problems we're trying to solve. We hire exceptional people and we recognize the importance of coaching others. We have a formal mentor search application that lets you find a mentor that works best for you based on location, job family, and job level.
