Who You Are

Are you passionate about design and development? Do you have experience building, deploying, and maintaining large-scale applications and/or consistent, user-friendly experiences? Are you ready to take your skills to the next level and join a team of innovative self-starters in a supportive, entrepreneurial environment?

As a Senior Software Engineer in the Platform Services cluster, you will help evolve our software architecture to support more parallelized development against multiple products without compromising the quality that has defined success for Justworks so far. You will leverage your experience working within a service-oriented architecture with a strong understanding of API, library, and framework design. You will be responsible for separating data and functionality as necessary and will demonstrate an understanding and use of automated testing as a productivity multiplier. You are eager to learn and passionate about improvement across multiple dimensions - in code, practices, processes, people, and customers. You want to understand how systems work, and you think about how to make them work even better. You will work closely with multiple domain teams to scope, design, and build new features and common functionality. You will be working primarily in Ruby on Rails, Kotlin, and/or JavaScript/Typescript + React, but prior knowledge is not a requirement.
