Wealthsimple Technologies - Senior Software Developer, Financial Risk
Requirements
• 4+ years of software engineering experience, ideally in a consumer-facing product environment • Strong backend engineering skills, with a track record of building reliable, scalable systems • Experience working on fraud detection, financial risk, or other high-stakes technical domains • Comfort across the stack — you're as comfortable contributing to a client-facing flow as you are to the systems running underneath it; experience with Ruby on Rails or Kotlin is a strong asset • Strong software quality practices: you write testable code, take production ownership seriously, and raise the bar in code review • Clear communicator who can work effectively with non-engineering partners across operations, compliance, and product • AI-first mindset. You leverage AI tools to accelerate development, improve code quality, and solve problems more effectively. You have already evolved your workflow through AI and are eager to continue innovating. • Experience with Apache Flink or other stream processing frameworks • Familiarity with real-time data pipelines and event-driven architecture • Experience with Temporal for workflow orchestration • Hands-on experience with AI-assisted development tools such as Claude Code or Cursor, including agentic workflows and MCP integrations • Background in fintech, banking, or another regulated industry • You take ownership end-to-end — from writing the code to making sure it works in production • You're comfortable with ambiguity and operate well in a domain where the rules are real but the problems are rarely clean • Detail-oriented without losing sight of the bigger picture — you care about correctness, but you also want the experience to feel right for the client on the other side of it • Collaborative by default — you share context early, ask questions before you're stuck, and don't disappear into a hole for two weeks • Curious about the systems you're building and the risks you're mitigating — not just the code, but the why behind it
