Job description

Your Role


You'll write production code that ships to real customers. Not mock projects. Not busywork. Real code. Real impact.

Every week, you'll own features from start to finish - building them, testing them, shipping them. You'll work with experienced engineers who'll push you to write better code and think more deeply. You won't be stuck on sidelines work. You'll be building things that matter.


What You'll Actually Do


  • Write code that ships: Build features in Java and JavaScript that real companies use for their HR integrations
  • Work with real systems: Design and improve APIs that move employee data between platforms - understand the architecture behind what makes integrations work
  • Test like a professional: Write tests that catch bugs before they reach customers - this is how real engineers think about quality
  • Collaborate on real problems: Participate in code reviews, ask questions in design discussions, contribute ideas to how we solve problems
  • Learn from engineers who care: Work with senior developers who'll invest time teaching you best practices, debugging strategies, and how to think about building at scale


What You'll Get


  • Real production experience: Your code runs on a platform used by hundreds of companies. You'll have actual shipping experience when you graduate.
  • Mentorship that matters: Senior engineers who care about your growth - not just assigning tasks, actually investing in teaching you.
  • Competitive co-op pay: We pay fairly because we respect your time and contribution.
  • Flexible, remote-first environment.
  • Strong path to full-time: Many of our best full-time engineers started as interns here. If you're great, we want to keep you.


What We're Looking For


  • Currently studying Software Engineering, Computer Science, or a related field.
  • Solid foundation in Java and JavaScript.
  • Exposure to testing frameworks like Spring, JUnit, or similar .
  • Comfortable with REST APIs.
  • Genuinely curious about how systems work and why things break.


We especially want to hear from you if: You've built a small project from scratch, debugged something that seemed impossible, or felt intimidated by a codebase at first but figured it out anyway. That's the mindset that succeeds here.


Nice to have (but don't let this stop you from applying):


  • React or other frontend framework experience
  • GraphQL, SOAP, Groovy, or JMS experience
  • Previous internship experience
  • Open-source contributions


About Flexspring


We're a remote-first team across Canada building the iPaaS platform that powers HR data integration. Our customers include mid-market to enterprise companies that depend on us to reliably move employee data.

Why this matters for your growth: We actually invest in how we build software and how we work together. Code should be readable. Problems get solved thoughtfully, not rushed. Your input matters - even as an intern. We ship good work, not fast work.

At Flexspring, interns aren't bystanders. You work on real product features, get genuine mentorship, and many of our full-time engineers started exactly where you are.
