Full Stack Engineer
At Chexy, we're reimagining how Canadians manage their largest expenses—like rent, tuition, and insurance—by transforming them 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 $1B+ in annual payment volume and millions of transactions per month, we're building financial infrastructure that needs to be quick, reliable, and bulletproof.

About the Role
We're looking for a Full Stack Engineer to build features on Chexy Core (our web application). You'll work on both sides of the stack—from payment processing systems and APIs to user-facing web experiences that help Canadians manage their most important payments.

This role involves taking ownership of features end-to-end, from database and API design through frontend implementation and deployment. You'll build production-grade systems that move real money while creating intuitive user experiences. You'll ensure both our backend and frontend are clean, scalable, and performant.

What You'll Be Doing

Build features end-to-end on our Next.js web app (Chexy Core)

Develop payment processing features including inflows, outflows, and integrations with card networks and banking systems

Design and implement REST APIs and integrate them into frontend applications

Build user-facing features in Next.js and React with Tailwind CSS for styling

Work with PostgreSQL (backend) and Firestore (web app) for data modeling and queries

Write clean, well-tested code across both TypeScript backend and frontend codebases

Design responsive, accessible web interfaces that work across desktop and mobile browsers





Participate in code reviews for both backend and frontend contributions

Debug and resolve issues across the full stack in development and production

Collaborate with product, design, and mobile teams to ship cohesive features

Participate in on-call rotations for production systems

Who We're Looking For

4-6 years of full stack engineering experience building production web applications

Strong experience with Node.js and TypeScript for backend development

Strong experience with React and modern frontend development (Next.js experience is a plus)

Experience with backend frameworks like NestJS, Express, or similar

Solid understanding of relational databases (PostgreSQL) and NoSQL databases (Firestore or similar)

Experience building and consuming REST APIs with understanding of API design principles

Proficiency with CSS frameworks (Tailwind CSS preferred) and responsive design

Understanding of authentication systems and security best practices

Familiarity with financial systems, payment processing, or fintech products

Strong testing practices for both backend and frontend code

Ability to balance technical trade-offs between backend performance and frontend user experience

Strong communication skills and ability to work across teams

Ownership mentality with attention to code quality, system reliability, and user experience

Bonus Points





Experience with Next.js and server-side rendering

Familiarity with NestJS or similar microservices frameworks

Experience with Firestore or other NoSQL databases

Knowledge of Clerk or similar authentication platforms

Experience with financial systems concepts: ledgers, transactions, reconciliation

Familiarity with Google Cloud Platform (Cloud Run, Cloud SQL, Pub/Sub, Firestore)

Experience with payment integrations or banking APIs

Experience with Prisma ORM

Contributions to open-source projects

Design sensibility and experience working closely with product designers
