Senior Software Developer, Stablecoin
WFA Digital Insight
Wealthsimple’s Crypto team sits at the intersection of traditional fintech and decentralized finance, and this senior engineering slot puts you in the driver’s seat of that convergence. The focus isn’t just on adding another token to a list; you’ll be architecting the stablecoin stack that powers trading, transfers, and on‑chain workflows for a user base that already trusts Wealthsimple with billions in assets. Collaboration is baked in – you’ll partner with product, design, and security squads to turn complex blockchain mechanics into the kind of frictionless experience that defines the brand. Candidates should be comfortable moving between smart‑contract code, Web3 libraries, and full‑stack product work, while keeping an eye on the security and performance standards that a financial services firm demands.

ABOUT THE TEAM The Crypto team is at the forefront of Wealthsimple's expansion into decentralized finance, working to democratize access to crypto for millions of Canadians. We're a passionate group of crypto-native engineers and product experts building the next generation of crypto products. Our team combines Wealthsimple's commitment to simplicity and transparency with cutting-edge blockchain technology to create secure, user-friendly crypto experiences that put users in full control of their digital assets. ABOUT THE ROLE As a Senior Crypto Software Developer, you'll be instrumental in building Wealthsimple's crypto infrastructure from the ground up. You'll work at the intersection of traditional fintech and decentralized protocols, helping to bridge the gap between complex blockchain technology and intuitive user experiences. This role offers the unique opportunity to shape how over a million crypto clients interact with decentralized finance while maintaining Wealthsimple's high standards for security, reliability, and user experience. WHAT YOU'LL DO - Build and architect new crypto products that give users more control over their crypto assets.
- Design and implement integrations with leading DEXs, DeFi protocols, and wallet providers.
- Build stablecoin infrastructure and product experiences that make digital cash more useful across trading, transfers, and on-chain financial workflows.
- Enhance our existing crypto offerings by expanding asset selection and improving product functionality.

How to Stand Out
- Highlight concrete examples of stablecoin or DeFi integrations you’ve built, preferably with links to code repositories or demo videos.
- Prepare to discuss smart‑contract security audits you’ve performed; be ready to walk through a vulnerability you discovered and fixed.
- Show familiarity with both EVM and Layer‑2 environments by mentioning specific tools (e.g., Hardhat, Foundry) you use for testing.
- Emphasize remote‑work discipline: describe your async communication setup, time‑zone overlap strategy, and how you stay aligned with distributed teams.
- When asked about architectural decisions, reference trade‑offs you considered around gas efficiency versus readability.
- Bring a concise portfolio that includes a brief write‑up of the problem, your solution architecture, and measurable outcomes (e.g., transaction cost reduction).
- In salary discussions, focus on total compensation—including equity, remote stipend, and wellness benefits—rather than base pay alone.
