Our Team

The Platform API Infrastructure Engineering team’s mission is to build the world’s best Developer API by providing the highest levels of performance, quality, reliability, and security for both our customers and developers. We are looking for a exceptional people manager with experience building out Developer APIs to take on the role of Engineering Manager for this team.


In addition to working within Platform Engineering, many of our projects require collaboration with other product groups and we are leading the charge in defining best practices for developing APIs across the company. We are building a first-class and consistent developer experience, but we can’t do that in a vacuum; collaboration is critical!


In 2019, we are laying the groundwork for the next 3 to 5 years of evolving and scaling the Slack Platform. Some of our ownership areas include: consistency and backwards compatibility of the Slack Developer API, the Events API, and API Security Features.
