We are seeking an accomplished Senior Full-Stack JavaScript Engineer to lead the design, development, and optimization of high-performance, customer-facing web applications. The ideal candidate brings strong architectural thinking, hands-on technical depth, and the ability to mentor a team while upholding best practices across the stack.

You will own the end-to-end delivery of scalable, SEO-optimized, and visually rich experiences built on modern web technologies such as Next.js, React, and TypeScript, while leveraging AWS, Cloudflare, and GraphQL for performance, resilience, and extensibility.

Key Responsibilities

  • Architect, develop, and maintain full-stack web applications using Next.js, React, and TypeScript, following modern design and development standards.
  • Lead technical decision-making and enforce best practices in code structure, performance, testing, and documentation.
  • Collaborate with product managers, designers, and backend teams to translate complex business needs into scalable technical solutions.
  • Build and maintain reusable, performant, and accessible UI components using Chakra UI, Tailwind, or similar frameworks.
  • Integrate with headless CMS platforms (e.g., Contentful or equivalent) and Stripe for dynamic content and secure payment processing.
  • Implement robust data integrations using GraphQL and RESTful APIs.
  • Experience with PostgREST
  • Leverage Cloudflare for edge rendering, CDN caching, and performance optimization.
  • Enhance search capabilities through AWS OpenSearch and implement advanced SEO strategies and Core Web Vitals optimizations.
  • Mentor and guide junior engineers, conduct code reviews, and drive a culture of technical excellence and collaboration.

Core Skills & Qualifications

  • 5+ years of professional experience in full-stack JavaScript/TypeScript development.
  • Expert proficiency with React.js, Next.js, HTML5, CSS3, and modern build pipelines.
  • Strong understanding of Server-Side Rendering (SSR), Static Site Generation (SSG), and Incremental Static Regeneration (ISR).
  • Deep experience with state management libraries such as Jotai, Zustand, or Recoil.
  • Proven ability to architect and optimize large-scale web applications for SEO, performance, and accessibility.
  • Experience with AWS (Lambda, ECS/Fargate, OpenSearch, S3) and Cloudflare Workers or equivalent CDN-edge technologies.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
