Role
Who you are
- 6+ years of software engineering experience building production-ready distributed systems or data platform infrastructure
- Strong proficiency in Python and infrastructure tooling like Kubernetes and Terraform
- Proven experience designing and operating highly performant, observable backend systems
- Practical experience or deep familiarity with the modern AI ecosystem (e.g., serving open-source models, vLLM, Ray, model routing, or evaluation frameworks)
- Track record of owning technical projects end-to-end with high autonomy
- Our stack includes:
- Container & Infra: Kubernetes, Terraform, AWS GPU infrastructure

What the job involves
- The Machine Learning Infrastructure team builds the core foundation powering AI and GenAI initiatives across Wealthsimple. As our AI footprint expands, our priority is building scalable, cost-effective infrastructure that enables high-performance inference using open-source models alongside vendor solutions. Our responsibilities are to:
- Build and maintain infrastructure to host and serve open-source LLMs reliably on cloud/GPU systems
- Implement intelligent model-routing frameworks to optimize performance, cost, and latency
- Develop evaluation and benchmarking tooling (Evals) to test, validate, and compare model performance across use cases
- Set the technical direction for operating scalable LLM infrastructure company-wide
- As a Senior Software Engineer on the ML Infrastructure team, you will design and implement the core backend and infrastructure powering our AI systems. You will work closely with data scientists, platform engineers, and engineering leaders to scale our GenAI footprint efficiently and securely
- In this role, you will have the opportunity to:
- Build model-routing architecture (e.g., LiteLLM integration) to dynamically direct requests across internal and external models
- Provision and manage high-performance GPU infrastructure for serving open-source LLMs
- Build evaluation frameworks (Evals) that enable engineers and data scientists to benchmark model quality against production requirements
- Drive key cost-optimization and infrastructure efficiency initiatives without sacrificing system accuracy or reliability
Our take
Wealthsimple is one of a crop of robo-advisors trying to democratise investment management. These companies are disrupting the industry by automating many of the processes involved in investment, removing the need for human advisors.
But while other so-called robo-advisors are focused on courting the high end of the market, Wealthsimple is trying to provide the same types of tools and advice to all users, regardless of the amount they have to invest.
Wealthsimple does have higher fees than some other robo-advisors such as Betterment and Charles Schwab. However, the company believes that it provides a more user-friendly platform, tailored to millennials who will be attracted to Wealthsimple due to its ease of use and social impact offerings.
