Full Job Description

📋 Description

• Own the full lifecycle of high-impact, customer-facing web products used by 2,000 global brands including Samsung, Nike, L’Oréal and IKEA. From first whiteboard sketch through production release and continuous optimisation, you will architect, code, test and ship features that reach 25 % of the world’s online users and process 2.2 billion requests every single day.
• Drive the evolution of our Vue.js and TypeScript ecosystem. You will introduce new patterns, libraries and tooling (Vite, WebPack, Babel, micro-front-end orchestration) that raise code quality, reduce build times and enable seamless horizontal scaling across 450 servers worldwide.
• Collaborate daily with Product Managers, UX Designers, Data Scientists and Back-End Engineers (Go, Node.js, PHP) to translate complex business requirements into pixel-perfect, performant interfaces. You will co-own API contracts, performance budgets, accessibility standards and security guardrails.
• Champion a culture of automated quality. Write unit, functional and e2e tests with Jest, Cypress or Playwright; configure CI/CD pipelines; integrate error-tracking (Sentry) and real-time monitoring (Datadog) so that every release is confidently deployed multiple times per day.
• Research bleeding-edge web technologies and feed discoveries back to the team through internal Tech Talks, brown-bag sessions and documentation. Past spikes have led to the adoption of Web Components, edge-side personalization and AI-driven predictive prefetching.
• Mentor mid-level and junior developers through pair programming, daily code reviews and crisp technical feedback. Your guidance will shorten onboarding time and multiply overall team velocity.
• Optimise for a multi-device world. Ensure responsive, cross-browser experiences that load in <100 ms on 3G networks and feel native on iOS, Android, tablet and desktop.
• Contribute to our micro-service architecture by designing RESTful endpoints, caching layers and GraphQL schemas that power real-time segmentation and 1:1 personalization at massive scale.
• Keep security, privacy and compliance front-of-mind. You will implement CSP headers, OWASP best practices and GDPR-friendly consent flows that protect 100 TB of historical customer data.
• Embrace a remote-first, agile mindset. Join sprint planning, retros and daily stand-ups from anywhere in Turkey, while staying deeply connected through Slack, Miro and Notion.
• Influence product strategy. Your insights on user behaviour, performance metrics and emerging channels (WhatsApp, SMS, Web Push) will directly shape the roadmap of a $500 M-funded unicorn.
• Leave a legacy. Every line you ship contributes to 100 social-impact projects, Code Academy scholarships and women-in-STEM initiatives across 30 countries.

🎯 Requirements

• 5+ years of professional front-end development with deep expertise in modern JavaScript (ES6+), Vue.js 3 and TypeScript
• Proven track record of shipping production-grade applications that handle millions of daily users and sub-100 ms performance budgets
• Hands-on experience with build tools (Vite, Webpack, Babel) and micro-front-end architectures that scale across distributed teams
• Strong testing mindset: comfortable writing unit, integration and e2e tests using Jest, Cypress or Playwright and driving a TDD culture
• Solid understanding of web security best practices (OWASP, CSP, GDPR) and accessibility standards (WCAG 2.1)

🏖️ Benefits

• Work from anywhere in Turkey with a fully remote-first culture and flexible hours
• Direct impact on products used by 2,000 global brands and 25 % of the world’s online users
• Continuous learning budget for conferences, courses and certifications
• Competitive compensation package and stock options in a $500 M-funded unicorn
• Mentorship and career-growth paths that have produced 50+ engineering leaders across 30 countries
