As the Senior Data Security Architect, you will be Fastly's technical authority on protecting sensitive data across our corporate and production systems.

You'll partner with Product, Engineering, Legal, and System Owners (e.g. IT, Analytics, Business Systems, Finance) across Fastly to design and implement tooling to enforce our data requirements and meet our regulatory and customer data obligations. Fastly believes that protecting the data entrusted to us is everyone's responsibility, and you'll give the rest of the organization the tools and technical guidance to live up to that.

You will be supported by a friendly security team, where you can learn and develop. We check our egos at the door. You'll make sure our customers benefit from a service built to the highest security standards in the industry. We pride ourselves in our involvement in the larger security community and encourage our team to present at network and security conferences and participate in the open source community. We are a distributed security team with the commitment and tools in place to make it work.
