Build something people love

Wealthsimple is Canada’s leading financial innovator. The company offers a full suite of simple, sophisticated financial products across managed investing, do‑it‑yourself trading, cryptocurrency, tax filing, spending and saving. Wealthsimple currently serves more than 4 million Canadians and holds over $125 billion in assets under administration. It was founded in 2014 by a team of financial experts and technology entrepreneurs, and is headquartered in Toronto, Canada.

Wealthsimple’s Platform Engineering org builds the systems that the rest of engineering builds on. We operate Platform‑as‑a‑Product: our developers are our customers, and we are measured by the leverage we give them. Our work shapes how every engineer at Wealthsimple writes, ships, and runs code. When we do it well, the whole company moves faster and ships with more confidence.

You’ll join one of our Platform teams and take ownership of significant pieces of the developer experience. You’ll work hands‑on across the full lifecycle—designing, building, shipping, and operating the systems engineers depend on every day. You’ll lead projects end‑to‑end, partner with the teams that use what you build, and grow your influence beyond your immediate team.

This posting covers two distinct areas:

• Platform Engineering: you build the systems that enable engineers to build, ship, and operate software reliably and efficiently, including developer platforms, internal tooling, CI/CD and software delivery systems, cloud infrastructure and service frameworks, reliability and observability tooling, and large‑scale distributed systems. The focus is on improving developer productivity, system reliability, and software delivery speed.
• Data Platforms: you build the infrastructure that powers data, analytics, and machine learning across the company, including data ingestion pipelines and orchestration, large‑scale data warehousing, streaming and batch processing systems, data modeling, quality and governance, and analytics enablement. The focus is on delivering trusted, scalable, and high‑quality data systems.

• Improve reliability, scalability, and performance of core systems
• Work closely with internal users (engineers or data practitioners)
• Participate in operational ownership (on‑call where applicable)
