This is a hands-on role where you will design, build, review, and ship high-quality, responsive web applications while also mentoring other developers and collaborating closely with UX designers, product owners, architects, security specialists, and cross-functional stakeholders. This is an opportunity to have a strong voice in technical direction and to influence the future of OneSpan’s user-facing offerings.

This position is open to candidates residing in Montreal. This role is hybrid, with in-office presence 2 days per week at our Montreal office.

Design, build, and integrate micro frontends, contributing to dynamic architecture modeling and a modular, scalable frontend ecosystem.
Take part in system and architecture design decisions within an Agile team, partnering closely with backend, UX, and product.
Provide technical leadership by reviewing designs and code, identifying risks early, and guiding teams toward effective solutions.
Champion software quality by defining and enforcing best practices for unit, integration, and end-to-end testing.
Contribute to the design, evolution, and optimization of CI/CD pipelines built on AWS and GitLab, with a focus on automation and reliability.
Proactively identify opportunities to improve developer productivity, application performance, and user experience.
Mentor and coach intermediate and junior developers, providing technical guidance, feedback, and knowledge sharing.
Collaborate closely with UX design, product management, architecture, security, and other stakeholders to align technical solutions with business goals.
Support and troubleshoot complex production issues, contributing to root-cause analysis and long-term fixes.
Stay current with emerging frontend technologies and industry trends and help evaluate their adoption where appropriate.

Requirements

Bachelor’s or Master’s degree in Computer Science, Software Engineering, or a related field, or an equivalent combination of education and experience.
8+ years of professional experience designing, developing, and maintaining web-based frontend applications.
Deep expertise in JavaScript, TypeScript, HTML5, and CSS3, including responsive, cross-browser, and mobile-web development.
Strong, hands-on expertise with React and its ecosystem, including hooks, component design, and state management.
Proven experience with modular frontend architectures, including micro frontends, shared component libraries, and design systems.
Solid experience integrating with RESTful APIs, including data fetching, caching, error handling, and security best practices.
Strong focus on frontend performance optimization, accessibility and secure coding practices.
Familiarity with AI-assisted development tools (e.g., GitHub Copilot, Claude Code).
Experience with software best practices such as test-driven development (TDD) and continuous integration, and with unit, integration, and end-to-end testing frameworks.
Experience with CI/CD pipelines and automated build, test, and deployment workflows (preferably using GitLab and AWS).
Proficiency with Git and modern branching strategies and code review practices.
Strong problem-solving skills and the ability to debug complex frontend and production issues.
Experience teaching, guiding, and mentoring other developers.
Experience leading technical work end to end (designing, coding, reviewing, testing, and deploying).
Excellent written and verbal communication skills, with the ability to collaborate across engineering, design, product, and security teams.
Ability to work independently while taking ownership of frontend applications in a fast-paced Agile environment.

Preferred Requirements

Experience with Node.js / Express.js for frontend tooling, backend-for-frontend (BFF), or server-side rendering.
Experience with GraphQL client tooling such as Apollo.
Experience building and maintaining design systems and shared component
Strong understanding of Agile and DevOps practices.
Prior experience leading technical initiatives or acting as a technical point of contact for a team.
Experience influencing technical standards and best practices across teams.

Avis: Ce poste nécessite la maîtrise d'une langue autre que le français car vous serez en partenariat avec des clients internes et/ou externes hors du Québec.
