What they need


  • You’d be joining our Backend team within the Platform Engineering division. We’re a group with an unusual mandate inside MaintainX: we treat our internal developer platform as a real product, with internal customers (150+ developers), adoption metrics, and a roadmap shaped by what product teams actually need. We are not an ops team
  • The platform we’re building today exists to answer one question: how do we keep MaintainX engineers shipping fast as the org grows from where we are now to 2-3x the size?
  • Today, spinning up a new backend service, getting it to production, and operating it involves too many manual steps, too much tribal knowledge, and too many decisions each team makes in isolation. We want golden paths that make the right thing the easy thing
  • Design, build, and maintain backend foundations and tooling powering our internal developer platform
  • Bring AI native and add on workflows into your daily work and into the platform
  • Raise engineering excellence standards
  • Lead to the consolidation and evolution of platform primitives: developer portal, local development, domain-service templates and scaffolders, graphQL, event-driven, openAPI golden paths and CI/CD workflows
  • Collaborate with other platform teams and product development teams on defining and adopting the internal developer platform

Benefits

  • Flexible time off
  • Training and development investments
  • Competitive salary and equity opportunities
  • Comprehensive healthcare coverage- Expert in Node.js, TypeScript, or similar languages
  • Strong AI mindset
  • Good knowledge of cloud infrastructure and CI/CD pipelines
  • 5+ years of distributed systems experience
  • A product mindset: ability to build a platform with and for internal customers
  • An expert level of English, both spoken and written, is required, as the individual will need to lead platform engineering managers across multiple teams, present technical priorities to executive stakeholders, and align with engineering leaders outside Québec on a daily basis
  • Proficient designing, maintaining, and evolving GraphQL APIs at scale
