Senior Software Developer, Book of Record (Leverage)

Several years (5+) of professional software engineering experience, with a track record of building and operating critical production systems that people or businesses depend on.

Strong backend engineering skills and sound judgment about system design, reliability, and trade-offs.

We work primarily in Kotlin, with Kafka and GraphQL in the mix - deep experience in a comparable stack matters more than an exact match, and we'll help you ramp on ours.

Experience building services that are low-latency and highly available

You take production ownership seriously and stay calm and methodical when things go wrong.

You make the codebase and the people around you better through your reviews.

We're growing the Leverage team and looking for a Senior Software Developer to take real ownership of the services at the core of margin and lending.

You'll join a small, high-trust group of senior engineers and own meaningful scope from early on - designing and building the backend systems that track balances and calculate buying power and collateral.

It's backend-heavy, consequential work in a domain where the rules are real and the edge cases are plentiful.

You'll partner closely with Product, Design, and neighbouring engineering teams to turn complex financial logic into experiences that feel simple to the people relying on them.

Design, build, and operate the backend services that power balances, margin, buying power, collateral, and lending - the systems the rest of Wealthsimple trusts to be correct.

Own meaningful scope end-to-end, from technical design through to running your work reliably in production.

The Leverage team lives inside Book of Record (BOR) - the ledger of truth for every dollar that moves through Wealthsimple. Leverage owns the borrowing side of that ledger: the systems behind margin, portfolio lines of credit, and the lending products that let our clients do more with their money. When a client checks their buying power, borrows against their portfolio, or places a trade, our services are the ones deciding - accurately, and in real time - what's possible. We hold ourselves to a high bar, if you like problems where correctness genuinely matters and the systems have to hold up when markets open, you'll feel at home here.
