Software Engineer, Front-end

Our engineers build systems that catch bad guys.  Using all available payment, user, and machine data, we have to separate legitimate credit card transactions from fraudulent in under 400ms.  That means doing just-in-time mash-ups of internal data with external APIs and reducing it all into a single score with a few critical insights for end-users.

To solve this problem, we're looking for world-class engineers who are eager to learn, adopt, and contribute to a reactive style of programming.  

As part of our core offering, we provide a data-rich fraud research tool to our users which is a highly interactive single-page application built on AngularJS.

Moving forward, we have been building new features in ES2015/2016 (ES6/7) & ReactJS with the goal of migrating our core offering to a more modular and component based architecture. The position will involve maintaining the existing application and migrating/implementing new functionality in a more modern approach.. Our front end engineers frequently take mockups, wireframes,or even just functional spec and create rich user interfaces.

We prefer live coding/a conversational approach in our interviewing vs esoteric programming trivia. Skills, knowledge, and opinions in the vast front end ecosystem is what we are looking for.

  • Excellent programming skills in Javascript(ES5/6/7), React, AngularJS, HTML, CSS (LESS/SASS)
  • Ability to create pixel-perfect code from finalized visual designs
  • Experience with large React and Angular 1.x applications
  • Experience with one or more build tools such as Webpack, Grunt, Gulp, etc.
  • A test-driven approach to front-end development
  • Experience using Git in a collaborative environment
  • Analytical problem solving skills

Bonus Skills:

  • Experience/knowledge of functional programming in Javascript
  • Experience with typed Javascript using Flowtype or Typescript
  • Experience with 3rd party APIs, OAuth, E-commerce plugins
  • Startup experience
  • Some server-side development experience with Python, Java, Node.js or similar language/framework
  • Data visualization experience using Google Charts or similar toolset
  • Experience with UX and or UI design a big plus

Typical Education:

  • B.S., M.S., or Ph.D. in Computer Science, Electrical Engineering, Math, or other technical field
