Описание

Looking for impact in eCommerce?

Join a market leader in the Shopify ecosystem and help shape the future of online retail.

Vitals is an all-in-one Shopify app that 110+ million shoppers interact with every month across 30,000+ stores worldwide. We’ve earned a perfect 5/5 rating (with thousands of glowing reviews) on the Shopify App Store, placing us in the top 0.1% of 13,000+ Shopify apps.

As a profitable, bootstrapped company, we focus solely on delivering value to our merchants – no vanity projects or red tape, just a laser focus on building products that drive results. If you’re an experienced JavaScript engineer who thrives on innovation and is excited about using AI-powered development tools to boost productivity, this job is for you.

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 fech & 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 (Responsabilities)

• 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.

What we're looking for (Requirements)

• Senior Front-End experience: 8+ years of hands-on JavaScript/FrontEnd development. You have deep knowledge of modern FrontEnd frameworks (preferably React or similar) and TypeScript.

• AI-driven developer: Proven experience or strong interest in using AI tools for development. You’re familiar with tools like Claude Code, Cursor, or similar, and you actively use them to improve code quality and delivery speed.

• Strong problem solver: You excel at thinking in trade-offs and choosing the right solution for the situation. There’s no one “right” answer in engineering – you weigh pros and cons to make pragmatic decisions.

• Proactive & product-focused: You take initiative to identify what needs to be done without always waiting for direction. If something doesn’t feel right (technically or from a user experience perspective), you speak up and propose better solutions.

• Resilient & creative: When faced with an “impossible” task or a complex bug, you get excited by the challenge rather than discouraged. You enjoy brainstorming and aren’t afraid to think outside the box to find a solution.

• Strong communicator: You communicate clearly and early. If a potential issue arises, you raise it before it becomes a blocker. You can explain technical concepts to non-engineers and collaborate well in a remote team.

Bonus points

• Polyglot developer: Experience with multiple FrontEnd frameworks (React, Angular, Vue, etc.), and deep VanillaJS expertise. You can quickly adapt to new libraries and paradigms.

• Performance tuning: Knowledge of advanced performance optimization techniques for web apps (lazy loading, caching strategies, minimizing bundle size, etc.). Experience making dynamic storefronts lightning-fast is a plus.

• Build tools mastery: Familiarity with modern build systems and tooling (Webpack, Parcel, Vite, etc.) and the ability to configure and optimize them for large projects.

• Additional AI/automation experience: If you’ve experimented with other AI-driven development tools, automated testing frameworks, or CI/CD optimizations using AI, we’d love to hear about it.

What we offer

• Competitive compensation: We reward top talent with competitive pay.

• Remote work, always: Freedom to work from anywhere in the world. We trust you to get work done in the environment that suits you best. (Our team currently operates around EMEA time zones for collaboration.)

• Growth & learning: Work on a product at a massive scale using the latest tech. You’ll have opportunities to experiment with new technologies (including AI tools) and grow your skill set. We support continuous learning and will cover resources that help you advance.

• Impactful work: Your contributions directly shape the product and user experience for thousands of merchants and millions of shoppers. Few roles out there offer this level of influence on real-world outcomes in e-commerce.

• Supportive team culture: Join a tight-knit team that values transparency, ownership, and work-life balance. We celebrate diversity and believe in empowering each team member. You’ll find us candid, down-to-earth, and always ready to help each other succeed.
