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.

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.
