  • Write production-quality code for test systems, utilities, and supporting infrastructure
  • Improve developer experience by enabling fast, reliable feedback loops
  • Validate complex payment flows and external integrations (e.g., Stripe) through automation-first approaches
  • Lead root cause analysis for defects and implement systemic fixes to prevent recurrence
  • Define and enforce quality standards for high-reliability, revenue-critical systems
What You Bring
  • 5+ years of experience in software engineering, SDET, or test automation roles
  • Proven experience designing and maintaining test automation frameworks at scale
  • Experience with API, integration, and end-to-end testing patterns
  • Strong understanding of CI/CD systems and test pipeline optimization
  • Experience improving test reliability, performance, and maintainability
  • Ability to design systems for testability (e.g., dependency injection, contract testing)
  • Experience working with distributed systems and understanding failure modes
  • Experience with payments, e-commerce, or financial systems (preferred)
  • Strong collaboration skills and ability to influence engineering practices
What We Offer
  • Generous PTO and competitive pay 
  • Fullscript's RRSP match program for financial health 
  • Flexible benefits package and workplace wellness program
  • Training budget and company-wide learning initiatives 
  • Discount on Fullscript catalog of products 
  • Ability to work Wherever You Work Well*
 
*Our Wherever You Work Well philosophy means Fullscript teammates get to pick their own office - whether that's in-office, at home, or a bit of both
