About Flexspring


Flexspring builds technology that helps companies connect their HR systems and move people data smoothly between tools - without manual work.


We’re a remote-first team spread across Canada and beyond, and we care a lot about how we build things and how we work together. At Flexspring, interns and co-op students don’t sit on the sidelines. You’ll work on real product features that are used by real customers, and many of our interns join us full-time after graduation.






Full Stack Software Developer – Co-op / Internship


Location: Quebec-based (Montreal preferred)
Duration: 4+ months






The Opportunity


We’re growing and looking for a Full Stack Software Developer Co-op / Intern to join our R&D team.


If you’re excited about building things that actually ship, this role is for you. You’ll work mainly in a Java-based stack, help develop Flexspring’s core platform, and learn how real SaaS products are designed, tested, and improved over time.


This is a hands-on role where you’ll code, learn, ask questions, and contribute—every week.






What You’ll Be Working On



  • Building and improving features in Flexspring’s product

  • Writing backend and full stack code using Java and JavaScript

  • Working with APIs and data flowing between systems

  • Writing and running tests to make sure things work as expected

  • Collaborating with experienced developers through code reviews and team discussions







What We’re Looking For



  • You’re currently studying Software Engineering, Computer Science, or a related field

  • You have a solid foundation in Java and/or JavaScript

  • You’ve been exposed to Spring and JUnit (school projects count!)

  • You’ve worked with or learned about APIs

  • You’re curious, motivated, and enjoy solving problems







Nice to Haves



  • Experience with REST APIs, React, GraphQL, Groovy, JMS, or SOAP

  • Interest in SaaS products or system integrations

  • Curiosity about how large systems talk to each other







What You’ll Get Out of It



  • Real experience working on a production SaaS platform

  • Mentorship and support from senior developers

  • Exposure to real-world engineering practices

  • Competitive co-op pay

  • Flexible hours in a remote-first environment

  • A strong chance to grow into a full-time role after graduation
