Our team solves tough, meaningful problems that create a safer, more secure world. We are seeking a Principal Platform Engineer to support this need as a hands-on engineer, but also to lead the design and evolution Developer ecosystem as a Product Owner, or in a Scrum Master capacity. This role focuses on building intuitive, self-service workflows that enable development teams onboard, deploy, and operate software efficiently across secure environments.
