  • Must have worked on at least two recent projects where Next.js was the primary frontend framework
  • Deep knowledge and at least 3 years of hands-on experience with a modern framework such as NestJS, Fastify, or Hono
  • Strong understanding of Fastify, including its main advantages, validation and serialization, and authentication and authorization mechanisms
  • Strong proficiency with PostgreSQL and/or Supabase, including query optimization and schema design
  • In-depth, practical knowledge of Prisma or Drizzle ORM, with experience in building complex queries and managing migrations
  • A profound understanding of caching strategies (e.g., in-memory, distributed cache, CDN) and the ability to apply them effectively to optimize performance (e.g., using Redis)
  • Full proficiency with Docker for creating, managing, and deploying containerized applications
  • Experience with Docker Compose is essential
  • Understanding and practical application of background workers and message queues (e.g., BullMQ, RabbitMQ) for handling asynchronous tasks
  • Proven experience in building secure systems, including protecting against common vulnerabilities (OWASP Top 10), configuring Content Security Policy (CSP), CORS, securing APIs, and hardening hosting environments
  • Experience working with analytics tools (e.g., Google Analytics, PostHog, Mixpanel) and platforms for A/B testing
  • A genuine passion for teaching, sharing knowledge, and helping team members grow professionally
  • Excellent communication skills, with the ability to articulate complex technical concepts clearly to both technical and non-technical stakeholders
  • The ability to understand business objectives and translate them into technical solutions that deliver real value to users

Nice to have:

  • Experience with CI/CD pipelines (e.g., GitHub Actions, GitLab CI)
  • Experience writing unit and integration tests (e.g., Jest, Playwright)
What we offer:
  • Remote Work Environment: Embrace the freedom to work from anywhere, anytime, promoting a healthy work-life balance
  • Unlimited PTO: Enjoy unlimited paid time off to recharge and prioritize your well-being, without counting days
  • Paid National Holidays: Celebrate and relax on national holidays with paid time off to unwind and recharge
