About the role: 

  • You’ll work to ensure quality while we bring cutting edge features to market; from concepts through requirements, use cases, implementation, unit testing, surrounding automation testing and on through live deployment, your involvement is crucial. 
  • You’ll help use the latest testing tools, technologies and best practices to rapidly improve test coverage of our microservice-based architecture. 
  • You’ll push the boundaries and discover breakages and bottlenecks on the platform through API testing, load testing, and automated user testing. 
  • You’ll bring new ideas and technologies to the table and improve our overall quality assurance. 
  • You’ll develop and improve existing test plans, automation, and show our testing coverage improving over time.

  • Pick your preference of a Mac and/or PC (Windows or Linux), and whatever development tools you need, and we’ll get you hooked up. 
  • Come to work at our Fredericton Office and enjoy both an open and non-open layout to maximize your productivity. 
  • Take time off when you need it with our unlimited vacation policy and our flexible work schedule. 
  • Enjoy office snacks and staff lunches on a regular basis (Covid-19 safety permitting). 
  • Take a break, play video games, or enjoy some quiet time in one of our several break rooms. 
  • Competitive compensation, health benefits, and RRSP matching plan. 

About you: 

3+ years commercial/enterprise software quality assurance experience 

3+ years in developing tools that are directly related to quality testing 

1+ years working directly with cloud native microservices 

A proven history of a strong contribution within a team effort in delivering high quality software on schedule. 

Ideally, you will…

  • Offer constructive feedback during code reviews, as well as positively receiving and executing on the feedback offered by others. 
  • Have a Bachelor's Degree in Computer Science, related field, or equivalent real-world experience with a firm grasp of Software Engineering/Computer Science fundamentals. 


You’ll impress us even more if you have experience with some of these: 

  • Software architecture experience in a high volume enterprise cloud platform environment 
  • Selenium experience (or other web testing tool experience) 
  • CI/CD experience 
  • API testing experience 
  • Performance testing experience (platform load testing, API SLOs)
