Senior Software Engineer, Fraud Prevention

Who You Are

Are you passionate about design and development? Do you have experience building, deploying, and maintaining large-scale, distributed applications? 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 part of the larger Employer Risk vertical, Fraud Prevention is a new team built from the ground up. The team will focus on building the backend services and frontend experiences and toolings to automate and scale the detection and prevention of fraudulent entities and activities in the Justworks platform. We work closely with cross functional partners across multiple business domains.

As a Senior Software Engineer in the team, you will be one of the founding engineers to build 0 to 1 software services and tools. You will be leveraging your experience working within a service-oriented architecture. 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. You want to understand how systems work, and you think about how to make them work even better. You will work closely with product managers, UX designers, and other engineers to scope, design, and build new features and functionality. You will be working primarily in Ruby on Rails and/or JavaScript/React, but prior knowledge is not a requirement.
