Paperless Post is seeking a Software Development Engineer in Test (SDET) to join our team of multidisciplinary engineers, specifically our Editor team which develops our invitation and card creation tool. In this role, you'll develop and maintain automated test frameworks specifically designed to handle complex visual rendering, creative interactions, and non-standard browser behaviors. You'll write automated test scripts that validate both functionality and creative output, collaborate with developers on testability for innovative UI components, and integrate tests into CI/CD pipelines. This role requires a unique blend of software engineering and quality assurance expertise, with a particular focus on testing rich interactive experiences and visual fidelity. Our stack includes Typescript, React, Next.js and GraphQL on the frontend, with services written mostly in Golang with sprinkles of Ruby running on top of PostgreSQL and MongoDB. We run on AWS with Kubernetes, Helm, and Terraform, and deploy with CircleCI and ArgoCD. The Paperless Post Engineering team, a highly collaborative group of developers and technologists, is charged with building and refining a consumer-facing product that millions of people interact with each month. Our individual feature teams each focus on a unique piece of the user experience and are made up of engineers, product managers, quality assurers, and product designers. We prioritize creativity and continuing education, and our ongoing commitment to quality code shows in our pragmatic but brave approach to technology.
