We're proud of what we've built — and we're just getting started. Read our Culture Manual and learn more about how we work.

About The Team

The Complex Accounts team builds the accounts that don't fit a standard mould. We own how businesses, from sole proprietorships to corporations with layered ownership, open and manage their accounts with Wealthsimple, along with joint accounts and registered education savings plans (RESPs). As we expand into more account types, the list keeps growing. It's work where accuracy, security, and regulatory requirements are non-negotiable, and we partner closely with operations, compliance, design, and product to make complicated financial structures feel simple for the people using them. We’re part of Data & Engineering, where quality, security, and scalability are the standard, not trade-offs.

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

• Build and evolve the systems that let businesses, joint owners, and families open and manage accounts with Wealthsimple


• Design data models for complex ownership — corporations, co-owners, and the people behind them


• Work with compliance and operations partners to turn regulatory requirements into reliable, well-tested software


• Improve the account opening experience across mobile and web, removing friction wherever clients get stuck


• Build tools that help our operations teams serve clients faster and handle unusual cases on their own


• Share on-call responsibilities and fix the root causes of recurring issues


• Use AI tools as a core part of how you build, and help shape how the team works with them


• Raise the technical bar through design reviews, code review, documentation, and mentorship

Skills you bring

• 5+ years of professional software development, with depth in back-end systems and a track record of shipping production systems that clients and teams depend on


• Full-stack experience: you’re as comfortable contributing to a client-facing flow on web or mobile as you are to the services running underneath it


• Experience modelling complex domains and designing systems that handle sensitive data, including authentication, fine-grained authorization, and auditability


• A track record of shipping in a regulated domain alongside compliance or operations partners


• An AI-first development workflow that doesn’t compromise on rigour: you use agentic tools day to day and know how to verify their output before it reaches production


• Clear communication: you can explain a technical trade-off to engineers, compliance partners, and leadership alike

Nice-to-have's

• Experience with Ruby on Rails, React / React Native, or TypeScript


• Familiarity with KYC/KYB processes, including business verification and beneficial ownership


• Knowledge of Canadian business structures (corporations, trusts, partnerships) or registered accounts like RESPs


• Experience at a fintech or financial services company

Why Wealthsimple?

• 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*


• Employee resource groups, including Rainbow (2SLGBTQ), Women of WS, and Black at WS


• We are a hybrid team with over 1,500 employees across North America. The people are one of the best parts of working here: you'll collaborate with incredibly talented, curious, and driven teammates who are deeply committed to doing great work.

• Unlimited paid sick days, Wellness Days and the 90 day away program do not apply to certain roles.
