  • Resolve security vulnerabilities across the application and its dependencies
  • Build and maintain shared developer tooling, CI linting, and quality-of-life improvements
  • Maintain and evolve shared infrastructure such as feature flags, end-to-end tests, and infrastructure-as-code within the monolith
  • Support product teams by solving cross-cutting technical issues
  • Act as a multiplier by unblocking other teams and improving the systems they rely on
  • Contribute through implementation, code review, technical guidance, mentorship, and documentation
What you bring to the table
  • Strong experience with Ruby or Ruby on Rails
  • You are a passionate software engineer who cares about your craft and serving other developers as your end users.
  • You are excited to learn, lead projects and want to produce the best work possible.
  • Experience designing maintainable systems and making pragmatic technical tradeoffs
  • Strong testing habits and an understanding of how tests support long-term maintainability
  • Comfort working on platform, infrastructure, tooling, or developer experience problems
  • A desire to improve engineering standards across teams
  • Strong communication skills and the ability to collaborate across engineering teams
  • A willingness to learn, ask questions, and receive feedback
Bonus if you have
  • Experience scaling or working on high-scale web applications
  • Past experience working in e-commerce or health tech sector
  • You've worked with React or GraphQL in the past
  • Experience improving CI systems, test suites, feature flag systems, or developer tooling
What we can offer you
  • 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
