Javascript Front-end / UX Engineer

Posted on: September 15th, 2017 Kelowna, BC Ronin HR Inc.

Javascript Front-end / UX Engineer

BlockCAT is a platform that makes Ethereum smart contracts (code that runs on the blockchain) easy to use. Blockchain technology is on the rise, and BlockCAT is on the leading edge of the field. If you have a passion for exploration, trailblazing, and dictating the evolution of early technology with massive potential, this is the place to be.


You are precise, meticulous, and you take great pride in your craft. You enjoy writing code with great care and intention, and hate the idea of sloppy code that is written as a means to an end instead of an end in itself. You believe that untested code is inherently broken code, and you think automation is valuable where it counts. Clean, robust, maintainable code is your priority, but you always know where to draw the line in order to keep up the deployment velocity. If this sounds like the kind of engineer you are, then we want to hear from you - even if you don’t exactly meet all of the listed requirements, just outline why you think it’s not a problem.

BlockCAT is an equal opportunity employer, and welcomes those of all ethnicities, sexualities, and denomination.

This is a full-time position based in Kelowna.


Role description:

As a BlockCAT Front-end engineer, you’re the guardian of the end user. You know what makes a great UI tick, and you have the skills to make that happen. You’ll be responsible for designing, creating, and maintaining the interface of the BlockCAT platform, as well as connecting the UI to the Ethereum blockchain using web3 technology. The UI is the heart of what drives BlockCAT, and this is the opportunity to be in the driver’s seat. If you are independent and self-starting, enjoy working with cutting edge technology, and aren’t afraid to dig deep to find answers, then this is the role for you.


What we’re looking for:

  • You have previous experience in building web-based products and the technologies involved.
  • The details matter to you, and you take pride in building a fantastic user experience.
  • Javascript is something you enjoy.
  • Drive to constantly re-invent and improve yourself and your work.
  • You think code isn’t ever “done” until it’s been tested.
  • You employ best practices, and you actively keep yourself up to date on changes that affect your stack.
  • You’re familiar (but not necessarily experienced) in the full web stack. You know how HTTP works, and the idea of implementing HTTP endpoints doesn’t scare you.
  • You live technology, and you’ve got a strong eye for good design.
  • Peer review is something that you value.


Key responsibilities:

  • Drive the full lifecycle of front-end user interface design, from conceptualization to maintenance.
  • Contribute design decisions and dictate the ecosystem that will drive the BlockCAT platform.
  • Develop key pieces of the BlockCAT platform to interface with the Ethereum blockchain.
  • Coordinate and work closely with the BlockCAT team in an early stage startup environment.


Requirements and Qualifications:

  • B.Sc in Computer Science or equivalent degree or work experience
  • 2+ years in front-end development experience in Javascript, with experience in asynchronous programming
  • 2+ years in HTML/CSS experience
  • 2+ years experience in interacting and utilizing third party APIs
  • 2+ years experience in a major Javascript UI framework (Bootstrap, React, Meteor, Angular, etc.)
  • 2+ years in UX, HCI design



  • Blockchain experience with Ethereum, web3, or a similar technology.
  • Interest in cryptocurrencies (Bitcoin, Ethereum, Dogecoin, etc.)
  • Prior experience in the financial technology sector.
  • Experience in system administration, networking, or working in a DevOps role
  • Love for cats.
