• Collaborate closely with product managers, designers (using Figma), and other engineers (using Slack, Graphite) to translate requirements into effective technical solutions.
• Write high-quality, well-tested code across the stack, utilizing testing frameworks (Playwright, Zerostep) and ensuring observability with tools like Sentry and Datadog/Posthog.
• Contribute significantly to architectural decisions, technical strategy, and the evolution of our overall platform.
• Develop and maintain CI/CD pipelines using GitHub Actions and Expo Application Services (EAS) for automated testing (Browserstack) and deployment.
• Stay current with and leverage modern development tools and methodologies, including AI-powered tools like Cursor.
