The Role

As security hire #1, you will be responsible for building out a small but effective security team, that will define, drive and deliver our security posture.

You will be responsible for auditing, implementing, and extending security functionality within our services and the platform upon which they run. We believe that usability is a major factor in how effective a given security feature will be, and that the best security is invisible to the user.

We assert that "DevOps" as originally envisioned, is about a culture of end-to-end ownership and collaboration, and not about job titles or the industry that has sprung up around this term. In this vein, all of our Software Engineers are responsible for deploying and operating their software, and any directly supporting infrastructure.

We appreciate economies of scale, automation and homogeneity, which is why we have a Platform Engineering team responsible for maintaining the core infrastructure and providing a platform (built upon Kubernetes, Terraform, AWS, Vault and Concourse CI, among other things) complete with tooling, re-usable components and solutions, to our cross-functional production engineering teams. We want to take a similar approach with our security team, baking security into the platform.
