About The Position

The AI Systems team is focused on building Wealthsimple's first-party AI tools and platforms. We design, develop, and operate the systems that bring AI capabilities directly into the hands of our teams and clients - from intelligent assistants and workflow automation to internal productivity tools powered by large language models. We're looking for software developers who are excited about building production-grade AI systems end-to-end: from frontend interfaces to backend services, infrastructure to deployment. This isn't a research role - it's a hands-on engineering role where you'll ship real products, collaborate with stakeholders across the company, and continuously evolve our AI platform as the technology and our needs grow.

Requirements

• Experience building and shipping production software as a full-stack or backend-focused developer.
• Strong proficiency in Golang and React, or demonstrated ability to ramp quickly on both.
• Hands-on experience with containerized architectures (Docker, Kubernetes) and cloud-native deployment patterns.
• Interest in or experience with AI/ML systems, LLM integrations, or building AI-powered products.
• Ability to work across the full stack - from crafting user interfaces to designing APIs and backend services.
• A product-oriented mindset: you care about the end-user experience and work with stakeholders to deliver features that solve real problems.
• Clear communication with both technical and non-technical teams.
• Comfort operating in a fast-moving environment where priorities and technology evolve quickly.

Nice To Haves

• Experience building developer tools, internal platforms, or productivity software.
• Familiarity with LLM APIs (OpenAI, Anthropic, etc.), prompt engineering, or retrieval-augmented generation (RAG) patterns.
• Background in building event-driven or streaming architectures.
• Experience with CI/CD pipelines and infrastructure-as-code.
• Background in financial services or regulated industries.

Responsibilities

• Design, build, and operate first-party AI tools and platforms that serve internal teams and Wealthsimple clients.
• Develop full-stack features across React frontends and Golang backend services, delivering complete, production-ready systems.
• Work closely with stakeholders across product, engineering, operations, and business teams to identify opportunities for AI-driven features and translate them into working software.
• Build and maintain containerized microservices, ensuring our AI platforms are reliable, scalable, and easy to deploy.
• Integrate large language models and other AI capabilities into our tools through well-designed APIs and service layers.
• Contribute to platform architecture decisions, helping shape how AI systems are built and operated at Wealthsimple.
• Iterate quickly on new features and prototypes, balancing speed of delivery with long-term maintainability.
• Establish patterns and best practices for AI system development that other teams can adopt.

Benefits

• Top-tier health benefits and life insurance
• Long-term group savings with employer match, through Wealthsimple for Business
• 20 vacation days, 4 wellness days, and unlimited sick and mental health days per year
• 90 days away: work outside Canada for up to 90 days per year
