About The Position

Our client is a Canadian fintech reimagining how people manage their money, starting with one of their largest recurring expenses: their monthly bills. The team built a leading position in the domestic bill-pay market and is now expanding toward a broader set of consumer financial products. The company moves hundreds of millions in annual transaction volume and operates with venture backing and a stable runway.

The next twelve months bring new products, deeper payments infrastructure, and a growing surface area across web and mobile. This role offers substantial ownership over what ships to a large consumer user base.
This is a senior, hands-on role. Everyone on the team writes code. The engineers who thrive here take an ambiguous problem, work it, ship it, and adapt when requirements change. You will lead on mobile projects while moving across the front end and into the back end when the work calls for it. The environment is fast-paced and rarely the same two weeks running.

You will own the mobile experience for a React Native application across iOS and Android, currently live and roughly at parity with web. The work is continuous improvement, new product surfaces, and ongoing experimentation rather than a from-scratch build. You will partner closely with product, design, and the rest of engineering to turn early ideas into shipped features.

Requirements

• 5+ years of software engineering experience
• 3+ years of mobile development experience, ideally building React Native applications for iOS and Android
• Experience navigating app store submissions and updates for cross-platform deployment
• Experience designing, implementing and maintaining RESTful APIs
• Experience with Git version control and release management
• Experience working with large datasets and NoSQL databases
• A track record of driving and delivering key initiatives in high autonomy, fast-paced settings
• Strong communication skills and the ability to explain complex technical ideas in accessible terms, contribute to cross-functional discussions, and thrive in a team that values mentorship, openness, and respectful discourse

Nice To Haves

• Experience with financial/payments APIs (e.g., Stripe, Flinks) and payments infrastructure
• Experience working in a startup setting and bringing applications to market from scratch (perhaps even as a former founder/founding team member)
• Proficient with CI/CD workflows and tooling
• Experience integrating mobile apps with Node.js back-end services in a full-stack environment

Responsibilities

• Ship and maintain features across the React Native app end to end, spanning architecture, code, testing, and release to the App Store and Google Play
• Contribute to front-end and back-end work as the problem demands, without being confined to a single layer
• Take ownership of projects, set the quality standard for surrounding engineers, and mentor others regardless of title
• Take a rough problem, determine what actually needs solving, execute, and adapt when requirements shift
• Write well-tested, maintainable code; engage in code reviews, refine development practices, and help optimize continuous integration and delivery workflows
• Participate in technical design discussions to ensure that systems can handle increasing transaction volumes and growing feature complexity, all while maintaining security, performance, and reliability
• Work closely with product, design, and other engineering team members to translate product requirements into technical solutions; share insights, mentor less experienced engineers, and contribute to a supportive, knowledge-sharing culture
• Keep abreast of emerging technologies and industry trends; experiment with new tools and approaches to ensure that the team’s technology choices remain efficient, current, and well-suited to the evolving product roadmap
