At Chexy, we're building modern financial tools for Canadians - starting with their largest expenses. We turn rent, tuition, insurance, and other big bills into opportunities to build credit, earn rewards, and gain financial flexibility. We're the first platform in Canada that lets users pay nearly any bill using their credit card, while unlocking meaningful benefits like cashback, points, and credit-building tools.

With ~$2B in annual payment volume and hundreds of thousands of transactions a month, we're building financial infrastructure that needs to be fast, reliable, and bulletproof. We're looking for a Senior Full Stack Engineer to own the product surface of Chexy end to end: our web app (Next.js), our mobile app (Expo / React Native), and the TypeScript backend-for-frontend that serves both. You'll be the most senior product engineer on the team.

You'll set the bar for product quality, decide how features are structured across web, mobile, and BFF, and be the person the team looks to when a flow is broken and nobody knows why. You'll ship the user-facing side of things that don't exist yet in Canada: a chequing account, a card we issue, instant payouts. Own the product surface across web, mobile, and the BFF - architecture, quality bar, observability, and roadmap Make the BFF the single reliable contract for web and mobile: strict schemas, versioning, and backward compatibility for app builds in the wild Set the technical bar: review architecture, write the patterns others follow, and push back when something isn't right What Senior Means Here You multiply the team - patterns, reviews, mentoring - rather than only shipping your own work Substantial experience shipping production TypeScript across the stack - React/Next.js at scale,



plus a real backend (Node - Hono, NestJS, Express - with a proper data layer) React Native / Expo in production, or a strong desire to own it and the judgment to get there rapid You already build with AI coding tools every day and have strong opinions about where they fail You communicate clearly in writing and don't need a manager to tell you what matters Bonus Points Design-system ownership, accessibility, or i18n (we ship in English and French) Datadog RUM or similar frontend observability The way software gets built is changing faster than anyone's best practices can keep up, and we're not pretending otherwise.

Most of what we ship is written with AI tools - but that's the least interesting part. The interesting part is working out what that means for how we review, test, and take responsibility for code: what you hand to a model and what you never do, what "I read the diff" means when the diff is two thousand lines, how a small team keeps quality up while moving faster than it should be able to. We're writing that playbook as we go, and we want people who want to write it with us, not people waiting to be handed it.

Work the way engineering works now: AI-native tooling, category-defining technology, and end-to-end ownership Early equity: Access equity in a high-growth fintech Toronto office: We work in-office 5 days a week You'll go through a mix of conversational interviews and technical deep-dives designed to show how you think, how you've solved real problems, and how you work with others. We use AI tools to help us organize and review applications; This posting is for an existing vacancy. If you require any accommodations or support during the hiring process, let us know and we'll do our best to help.
