  • You'll work with the team to build, maintain and optimize product features that focus on how our users best collaborate with one another.
  • You'll actively own team features or systems and define their long-term health, while also improving the health of surrounding systems.
  • You'll mentor other engineers and deeply review code.
  • You'll improve engineering standards, tooling and processes & bring best practices in planning, developing, testing and deploying industry compliant code.
  • On-call duties

About you:

  • You have a minimum of 3 years of professional experience in full-stack software development.
  • Strong programming skills in C# and/or TypeScript, with experience building production-grade applications.
  • Familiarity with React and Node.js, and an understanding of modern web authentication patterns.
  • Interest in Identity and Access Management (IAM) - including authentication, authorization, user provisioning, and permissions systems.
  • Experience designing and consuming REST or GraphQL APIs.
  • Proficient at writing understandable, maintainable, and testable code.
  • Strong communication and collaboration skills; comfortable working in a cross-functional environment.

Nice to have:

  • Experience integrating with SSO protocols such as OAuth 2.0, OIDC, or SAML.
  • Hands-on experience with Okta, Azure AD, or similar identity providers.
  • Exposure to SCIM or other user provisioning standards.
  • Understanding of token-based authentication (JWT, PKCE, token exchange).
  • Knowledge of encryption standards, SSL/TLS, or public/private key infrastructure.
  • Experience with React Native applications.
  • Experience with Docker and Kubernetes.
  • Experience with observability practices, as well as knowledge of observability tools such as Datadog.
  • Familiarity with cloud providers (AWS, Azure, GCP) and service deployment practices.
  • Experience with CI/CD pipelines and modern DevOps workflows to streamline testing and deployment.

What's in it for you:

  • Competitive salary and meaningful equity opportunities.
  • Healthcare, dental, and vision coverage.
  • 401(k) / RRSP enrolment program.
  • Take what you need PTO.
  • A Work Culture where:
    • You'll work alongside folks across the globe that reflect the MaintainX values: Smart Humble Optimists.
    • We believe in meritocracy, where ideas and effort are publicly celebrated.

About us:

Our mission is to deliver one platform for maintenance, repair & operations teams to keep the physical world running. We believe the greatest asset in any organization is the people.
