Senior Software Developer Identity Trust

Job Description

Build something people love

Wealthsimple is on a mission to help everyone achieve financial freedom by reimagining what it means to manage your money. Using smart technology, we take financial services that are often confusing and expensive and make them transparent and low-cost for everyone. We’re the largest fintech company in Canada, with 3+ million users who trust us with more than $100 billion in assets. And we’re just getting started.

We’re looking for someone who thinks big, sweats the small stuff and keeps things simple. You’ll join a high-bar, fast-paced team where people are trusted to own their work, communicate openly, and ship things that improve our clients’ lives. Collaboration, humility, and an obsession over quality are how we get stuff done.

About the team

Identity Trust team is focused on making Wealthsimple the most trusted place for Canadians to manage their wealth. We build and maintain the authentication, security, and permissions systems that protect over 3 million clients and more than $100 billion in assets.

Our work spans login experiences, two-factor authentication, in-app verification prompts, fraud prevention, and the permissions engine that gives clients control over who can view or act on their accounts. We’re looking for developers who care deeply about reliability and security, and who understand that trust is built through every interaction a client has with our platform.

The work includes designing systems that scale to ²⁴⁄₇ availability, building security features that give clients control without adding friction, and modernizing authentication infrastructure to support Wealthsimple’s continued growth.

In this role, you’ll have the opportunity to:

• Design and build security features that give clients control over how they access, move, and protect their money.
• Improve reliability to support 99.99% uptime across web and mobile experiences.
• Build and maintain authentication flows including passwordless login, push-based 2FA, and in-app verification prompts
• Work closely with product, security, fraud, and infrastructure teams to balance client experience with account protection.
• Prioritize delightful user experiences that minimize friction by adapting to risk signals without compromising security.
• Design systems that recover gracefully from failures and provide clear feedback to clients.
• Participate in on-call rotations for critical authentication infrastructure.

Our technologies:

• React and React Native
• Ruby on Rails for backend services, with some Kotlin and Java
• PostgreSQL and Redis for data persistence and caching
• AWS infrastructure
• OAuth 2.0 and OpenID Connect for identity protocols
• Datadog, Sentry and Mixpanel for monitoring and observability
• AI-assisted workflows

What you bring:

• Experience building authentication or security features across web and mobile (iOS, Android, or React Native) at scale.
• Strong frontend skills in React or similar frameworks, with an eye for building flows that are seamless without compromising security.
• Familiarity with native device security APIs (biometrics, secure enclave, keychain, and credential storage).
• Understanding of WebAuthn, passkeys, and browser-based authentication standards.
• Comfort working across the stack—collaborating with backend teams on APIs while owning the client-side experience.
• Track record of shipping features that balance security with usability.
• Clear communication with technical and non-technical teams.
• Not afraid of support work investigating and debugging individual client authentication issues.
• Comfort with on-call duties for critical identity infrastructure.

Nice-to-have’s:

• Experience with fraud detection or risk-based authentication systems.
• Background in financial services or regulated industries.
• Experience with session management, rate limiting, and bot detection.
• Experience building permissions or authorization systems (RBAC, ABAC, delegated access).
• Understanding of Open Banking standards and third-party data sharing.
