• Maintain authentication and account flows, including SSO integrations
• Review code and help maintain a high bar for quality, accessibility, and performance
• Collaborate with backend engineers on API design and propose technical approaches
• Write clear technical documentation and communicate progress, risks, and tradeoffs

What we're looking for

• 5+ years of commercial software development in production, enterprise, or B2B environments
• Strong React and TypeScript skills
• Commercial experience with React Native, including app store releases
• Practical experience with AWS and CI/CD (GitHub Actions or equivalent)
• Experience with Next.js or another SSR React framework
• Experience working with a component library or design system
• Ability to own features end to end, from requirements to production support
• Daily use of AI-assisted development tools

Experience with Tailwind CSS, Radix UI, Storybook, Playwright, Node.js or SQL will be a plus, but is not required.

What we offer

• Competitive compensation for a Senior-level position
• Direct communication with an international product team
• Full-time workload
• Fully remote, hybrid or office-based work
• Medical insurance
• Professional development and education reimbursement
• Support from the Quintagroup engineering team
