About the Client

Service outages, security breaches, performance degradations, and bugs in general are frequently the direct result of application and service misconfiguration. Our client is venture-backed, seed-stage startup looking to bring order to the configuration chaos of modern applications (particularly those that are cloud-native). By joining the project, you’ll be helping to improve the lives of developers, streamline devops, and keep customers happy.

We’re looking for a senior full-stack engineer to join our team. We’d love to work with someone that has experience building products and is comfortable with the ambiguity inherent to any early-stage company. The ideal candidate has experience in making judgment calls about where we can incur technical debt and when we need to start paying it down. Likewise, the ideal candidate knows when to go deep on a solution and when to ask for help or clarification.
If you love writing API-first web applications with either Ruby or TypeScript, you’ll fit right in.
