Senior Software Engineer (Front-end)

Signifyd·Belfast·Salary available on request


At Signifyd we’re creating a new market. We’re constantly improving and expanding the technology that has changed what fraud protection for ecommerce looks like. So we don’t have time for office politics. We understand that different people have different work styles and we thrive on variety while learning from each other. We’re all Signifyers, so we know that what needs to get done will get done.

Signifyd is a place where no one is going to tell you how to do your job. If you want help, you'll get it — from all quarters. But we pretty much figure out what needs to be done, who's in the best position to do it and then let that person roll-up her or his sleeves and have at it. We're protecting retailers from online fraud in a way that's never been done before and we could use your help. 

Oh, and a few particulars for this role:

To enhance all the awesome services we offer our customers, we are continually developing a host of apps to both support our internal operations and provide our customers with visibility at all levels.

As a Signifyd FE Dev you will be helping build new Apps as well as maintain and develop our existing ones using cutting edge modern JS and React. Of course we have the occasional crusty AngularJS app kicking around, so you’d also be helping to rewrite these and drive our codebase forward into React nirvana.

We’re using a stack that would make any modern FE dev cry tears of joy, but what’s better is you can have your say; we’re always adapting and experimenting to keep up with modern technology and patterns, so we would welcome someone who has ideas and isn’t afraid to try things out!

Some of the things we are looking for:

  • Excellent programming skills in Javascript (ES5/6/7)
  • Experience with large React applications (or other modern framework) 
  • A solid understanding of HTML and CSS.
  • Ability to create pixel-perfect code from finalized visual designs
  • Experience with one or more build tools such as Webpack, Grunt, Gulp, etc.
  • A test focused approach to front-end development
  • Comfortable moving between libraries / patterns / technologies
  • Experience using Git in a collaborative environment

Some things that would be nice to have:

  • Experience/knowledge of functional programming in Javascript
  • Experience with typed Javascript using Flowtype or Typescript
  • Experience with REST API and 3rd party APIs, OAuth, E-commerce plugins
  • Startup experience
  • Some server-side development experience with Python, Java, NodeJS or similar language/framework
  • Data visualization experience using Google Charts or similar toolset

Some of the stack we’re currently using:

  • ReactJS
  • MobX
  • Ant
  • DesignWebpack/Babel
  • Flowtype
  • Recompose
  • Lodash/Lodash-FP/Ramda
  • Jest/Enzyme

Tools/libraries/languages we have been keeping an eye on:

  • ELM
  • ReasonML
  • Clojurescript
  • Preact/Inferno/React Fiber
  • gRPC-web/GraphQL

We don’t want to brag, but we will look after you. Here’s some of what we offer:

  • A competitive base salary
  • An equally competitive equity package
  • Bi-annual performance related bonus (10% performance related)
  • Pension matched up to 8%
  • ‘Day one’ access to private Healthcare, Dental and Optical insurance scheme for you and your whole family
  • 25 days of annual leave (plus 10 stat)
