Senior Application Engineer - Enterprise Grid

Big companies simply don't work like small companies, and they don't use Slack the same way either. That's why there's Grid. With additional capabilities around scale, administration, security, and compliance Enterprise Grid brings the power of Slack to some of the world’s largest, most complex organizations including global brands like IBM, Condé Nast, Target, and Capital One.

Slack is looking for a Senior Application Engineer to be on the leading edge of scaling Slack to our biggest enterprise customers. If you love the idea of being responsible for taking Slacks reliability and security to the next level and can move quickly without compromising on quality then this is the role for you. Because of the nature of Slack’s product we continuously operate and interact with sensitive customer data, making this position on our Enterprise Grid team an extremely important and dynamic opportunity.

Trust is a key component of the partnerships we have with our largest enterprise clients and as a key member of the Enterprise Grid team, you will be solving the unique needs of enterprise Slack users at scale. Deploying Slack at scale means enabling end-users in large organizations to get work done in small, focused workspaces, while providing their administrators with centralized management of the data, policies, security & compliance capabilities that keep their users data safe and secure. 

At Slack, Application Engineers build the server-side of Slack using PHP / Hack, MySQL and Linux by working closely with a cross-functional team of product managers, designers, frontend, mobile, and quality engineers. Some of the areas you will be contributing to include data encryption, SAML, SSO, SCIM provisioning, third party application management, data retention, and APIs to support Slack’s ecosystem of security vendors.

At Slack, we place a strong emphasis on learning and sharing. Even if you haven’t worked on SAML, SSO, SCIM provisioning and enterprise grade software in the past, we will be more than happy to help you learn. All we ask in return is that you come with a willingness to learn.
