  • Solid understanding of server-side rendering (SSR/SSG) and performance concerns.

  • Experience with unit and/or E2E testing (Vitest, Jest, Playwright, Cypress, etc.).

  • Comfortable with Git, continuous integration, and working in an agile environment.

  • Excellent written communication skills essential in a remote setting.

  • Fluent English required (spoken and written); French is a plus.

Nice to Have
