Original job description

Your opportunity

We're supporting a fast-growing Canadian fintech that has reimagined how people manage their largest recurring expenses and is focused on helping them gain more value from every dollar spent. Already processing over a billion dollars in annual payment volume and serving a rapidly expanding user base, the company is building critical financial infrastructure while scaling how customers discover, adopt, and get value from the product. This role sits on the Growth engineering team, one of two engineering teams alongside Payments, and owns the surfaces where users first meet and engage with the product: onboarding, activation, and the core web experience.

As a Full Stack Engineer with a front-end focus, you'll spend the majority of your time crafting the user-facing web experience: building polished, performant interfaces in React and Next.js that make complex financial workflows feel simple and convert. You'll also work across the stack, contributing to the backend services and APIs that power those experiences, so full stack fluency matters even as the front end is where you'll do your best work.

This role emphasizes end-to-end ownership with a product lens. You'll ship quickly, measure impact, and iterate. From API integration through interface design, implementation, and deployment, you'll collaborate closely with product, design, mobile, and engineering peers to raise the bar on usability, performance, and conversion.

Key responsibilities

Frontend engineering: Lead development of user-facing features using React, Next.js, and TypeScript with a focus on performance, accessibility, and responsive design
UI implementation: Build responsive, accessible interfaces that function seamlessly across desktop and mobile browsers
Design collaboration: Partner closely with product designers to translate designs into polished, production-quality interfaces
Feature ownership: Build and own features end-to-end, from frontend implementation through the APIs and backend services that support them
API design and integration: Design, build, and consume REST APIs, ensuring frontend and backend contracts stay clean and reliable
Growth experimentation: Build and iterate on onboarding, activation, and conversion-focused features, using experimentation and analytics to guide decisions
Payments integration: Build user experiences on top of the payment workflows and banking integrations owned by the Payments team
Code quality: Write clean, well-tested code across frontend and backend codebases
Code reviews: Participate in code reviews across frontend and backend contributions to maintain quality and consistency
Debugging and reliability: Debug and resolve issues across the full stack in both development and production environments
Cross-functional collaboration: Work closely with product, design, and mobile teams to deliver cohesive customer-facing features
Operational support: Participate in on-call rotations to support production systems

Tech stack

Front-end: React, React Native, NextJS, TypeScript, Tailwind CSS
Back-end: Node.js/NestJS, TypeScript, Firebase
Infrastructure & tooling: Git, GCP

Your know-how

4+ years of experience building and shipping production web applications as a full stack or frontend engineer
Deep experience with React and modern frontend development, including state management, component architecture, and performance optimization
Strong experience with Next.js or similar React-based frameworks, including server-side rendering
Proficiency with modern CSS frameworks such as Tailwind and strong command of responsive design principles
A track record of building accessible, high-quality user interfaces that hold up under real-world usage
Solid experience with Node.js and TypeScript for backend development
Experience working with backend frameworks such as NestJS, Express, or similar
Experience designing, building, and consuming REST APIs
Working knowledge of relational databases such as PostgreSQL and familiarity with NoSQL stores such as Firestore
Understanding of authentication systems and security best practices
Familiarity with financial systems, payment processing, or fintech products
Strong testing practices, particularly on the frontend
Ability to balance frontend user experience with backend performance considerations
Clear communication skills and ability to work effectively across teams
Demonstrated ownership of code quality, user experience, and system reliability

It's a bonus if

You bring genuine design sensibility and have collaborated closely with product designers to shape, not just implement, user experiences
You have experience with frontend performance tooling, Core Web Vitals, or accessibility audits
You have hands-on experience with Next.js server-side rendering in production
You have worked with NestJS or similar service-oriented backend frameworks
You are familiar with Clerk or similar authentication platforms
You have worked on a growth or product-led engineering team, running A/B tests or building experimentation infrastructure
You are comfortable with analytics tooling such as Amplitude, Mixpanel, or GA4
You have experience operating services on GCP
You have built or integrated with payment providers or banking APIs
You have used Prisma ORM in production environments
You have contributed to open-source projects
