Platform Engineer

About Planning Center Planning Center exists to help churches build stronger, more connected communities. Since 2006, over 80,000 churches have trusted our tools to care for their people—whether that’s communicating with their congregation, organizing important information, or coordinating the details that make ministry happen. We’re an independent, profitable company with no outside investors. That means we get to focus on building products thoughtfully, caring for our team well, and making decisions for the long term. Our team is fully remote, working together daily through tools like Slack, Asana, Linear, Notion, and Zoom. Three times a year, we gather in Carlsbad, CA to connect in person, strengthen relationships, and align on where we’re headed.
