Customer Authentication Software Engineer

Affirm, Inc.

Shape customer authentication at Affirm by building secure login, MFA, and account access features from a remote Canadian location. Python or Kotlin skills support the work.

This Software Engineer II role sits within Information Security and focuses on next-generation customer identity and authentication. You will turn product requirements into backend services for registration, login, authorization, and account lifecycle flows. Your work will connect identity capabilities with web, mobile, and partner applications across B2C and B2B experiences.

Key Responsibilities:
  • Ship smoother login experiences and customer-facing authentication features
  • Build custom identity integrations for web, mobile, and partner applications
  • Contribute to design, readable code, automated tests, and reviews
  • Deploy scoped features to production with team support
  • Collaborate with engineering and product partners
Requirements:
  • Demonstrated software development through work, projects, or coursework
  • Foundational backend development knowledge
  • Understanding of application programming interfaces and databases
  • Interest in identity protocols or CIAM platforms
  • Willingness to learn through mentorship and code review

Bring backend development, secure authentication, API integration, and collaborative engineering skills to Affirm’s identity team.
