Full job description

Senior React Native Engineer (Mobile)

Location: Hybrid (Canada)

Type: Permanent or Contract‑to‑Hire

Experience: Senior (7+ years)

The Opportunity

Our client, a leading investment bank, is building a modern, cross‑platform mobile application and is looking for a Senior React Native Engineer to join as one of the founding members of its mobile engineering team.

This role offers a rare opportunity to help shape not just the application itself, but also the engineering standards, architecture, and ways of working for a growing mobile capability. The successful candidate will work on a large‑scale, customer‑facing product with significant reach, while having real influence over technical direction and the opportunity to grow into a leadership role as the team scales.

The application is being built using React Native with a shared codebase across iOS and Android, alongside targeted native development where required. While an initial release is underway, there is substantial scope for refactoring, optimisation, and architectural improvement, making this a strong “greenfield‑with‑context” environment.

What You’ll Be Doing

Design, build, and evolve high‑quality React Native applications across iOS and Android
Contribute to mobile architecture decisions, reusable components, and engineering standards
Work hands‑on across the mobile stack, including native iOS and/or Android development when needed
Help establish and improve best practices around testing, CI/CD, performance, and maintainability
Collaborate closely with product, design, QA, and business stakeholders in a squad‑based, agile setup
Act as a senior technical contributor through code reviews, knowledge sharing, and technical leadership
Support the growth of the mobile capability by mentoring future team members as the team expands

What Our Client Is Looking For

7+ years’ experience in software engineering, with deep hands‑on React Native experience in production environments
Proven experience delivering large‑scale, enterprise‑grade mobile applications
Strong foundations in native mobile development (iOS with Swift/Objective‑C and/or Android with Kotlin/Java)
Confidence working in mixed codebases that combine React Native and native platform code
Solid understanding of mobile architecture, performance optimisation, and engineering best practices
Experience with modern React Native tooling and patterns
Exposure to Expo (managed or bare workflows) is beneficial but not essential
Strong communication skills and experience working in cross‑functional teams
Previous experience mentoring or leading other engineers is highly valued

Why This Role Stands Out

Join as an early, influential engineer within a growing mobile engineering function
Work on a long‑term, high‑impact platform, not a short‑term engagement
Genuine opportunity to shape technical direction, standards, and culture
Strong emphasis on engineering quality and sustainable delivery
Clear pathway into technical leadership as the team grows
Hybrid working model that balances collaboration and flexibility

Pay: Up to $160,000.00 per year

Benefits:

Company pension
Dental care
Employee stock purchase plan
Paid time off

Work Location: In person
