Why you should join us

Thrive in the Shopify ecosystem : Be part of a team that’s building one of the most popular apps on Shopify. Your work will directly influence the success of tens of thousands of e-commerce businesses.

Remote-first flexibility : Work from anywhere (EMEA time zone preferred) with 100% remote forever.

Bootstrapped & stable : Join a profitable startup with real customers and steady growth. No external investors means we prioritize product quality and user happiness above all else.

Fresh tech & AI-driven culture : Work with a modern tech stack (TypeScript, Preact / React, Symfony, AWS) and a team that embraces new technologies. We use AI development tools (like Claude Code and Cursor) to code smarter and innovate faster.

Direct impact & ownership : Small, agile team where transparency, ownership, and diversity are valued. Your ideas can quickly shape product features used by millions, and you won’t be bogged down by bureaucracy.

What you will be doing (Responsibilities)

• Collaborate & ship solutions : Work closely with product managers and designers to plan, build, and ship new features that optimize the shopping experience and drive merchant sales. You’ll be involved end-to-end – from initial technical analysis and design to coding, review, and deployment.
• Leverage AI in development : Use AI coding assistants (e.g., Claude Code, Cursor) as part of your workflow to accelerate development, ensure code quality, and automate routine tasks. We encourage experimenting with new AI tools to boost productivity.
• Front-End development : Build fast and intuitive UI components and e-commerce features using TypeScript and React / Preact. Ensure our app’s widgets and interfaces are polished, mobile-friendly, and seamlessly integrated into merchants’ storefronts.
• Quality assurance : Write unit and integration tests (using Jest, React Testing Library, Playwright, etc.) to ensure features are reliable and bug-free. You’ll also monitor features in production and quickly squash any issues that pop up.
• Performance optimization : Continuously optimize applications for maximum speed and scalability. Whether it’s refining a React component or tuning an API call, you’ll make sure our app runs smoothly on stores of all sizes.
• Mentorship & code reviews : As a senior engineer, you’ll mentor less-experienced teammates, share knowledge, and lead by example. You’ll participate in code reviews and help uphold high engineering standards across the team.
