Requirements:

Competitive candidates will have:

• At least 5 years of experience with infrastructure security and/or software engineering

• Experience working with Kubernetes and Docker

• Familiarity with cloud environments such as GCP or AWS

• Ability to understand and contribute code to complex codebases

• Familiarity with various SSH key management approaches

• Deep understanding of service mesh technologies such as Istio, linkerd, or GCP Anthos

• Understanding of common CI/CD-based workflows

• Proficiency in Linux-based server environments with a high degree of comfort on the Linux CLI

• Experience architecting secure system designs to meet product requirements at scale

• Familiarity with zero trust concepts

• A demonstrated ability to work autonomously to identify and resolve problems independently

Outstanding candidates will have one or more of the following:

• Experience with common web application and web service design patterns

• Familiarity with Helm for managing Kubernetes deployments

• Previous experience in a technology startup

You will be a good fit if you are proactive and have a “get things done” mindset. Given our current pace of growth and load on our systems, most people have had a significant impact during their first week at the company.
