About Us

CypherLab is a forward-thinking technology company focused on building high-quality, play‑for‑fun and interactive entertainment platforms. We specialize in scalable system architecture, real‑time data processing, and modern web technologies. Our products emphasize user experience, performance, and technical excellence, and we work closely with international clients to deliver production‑grade software. We value engineers who think deeply, take ownership, and are comfortable working in an environment where technology choices matter. Curiosity, learning, and responsibility are core to our culture.

Role Overview

We are seeking a Senior Frontend Developer (Full-Stack) with strong expertise in Refine.dev and React to build and scale high-performance web applications. This role is frontend‑driven but full‑stack aware; you will own the frontend delivery lifecycle—from architectural decisions to deployment—while collaborating closely with backend, product, and infrastructure teams.

Key Responsibilities

• Design, develop, and maintain web applications using Refine.dev.
• Implement and optimize server‑side rendering (SSR) and rendering strategies.
• Build secure authentication and authorization flows.
• Define, consume, and enforce API contracts with backend teams.
• Establish and monitor frontend performance budgets (loading time, bundle size, Core Web Vitals).
• Collaborate with product, design, and infrastructure teams to ensure smooth releases.
• Write clean, maintainable, and scalable code.
• Conduct code reviews and contribute to frontend best practices.

Requirements

• Strong experience with JavaScript / TypeScript.
• Proven hands‑on experience with Refine.dev.
• Solid understanding of SSR, API integration, and web performance optimization.
• Experience working with REST and/or GraphQL APIs.
• Familiarity with CI/CD pipelines and modern deployment workflows.
• Strong ownership mindset with attention to scalability, reliability, and user experience.

Nice to Have

• Experience defining frontend architecture or performance standards.
• Exposure to backend development (Node.js or similar).
• Experience working in product‑driven or fast‑iteration environments.

Why Join CypherLab

• Work on production‑scale systems with real technical depth.
• Influence core frontend architecture and performance standards.
• Collaborate with a highly technical and execution‑focused team.
• Long‑term growth in a company that values engineering quality over hype.

If you enjoy solving real problems, care about code quality, and want to build systems that scale properly, we would like to hear from you.
