Senior Full Stack Engineer

Role Overview

As a Senior Full Stack Engineer at Skyzenix Technology, you will be the architectural backbone behind mission-critical client products, scalable SaaS platforms, and high-load web applications. You'll work closely with client founders, product managers, and our AI engineers to ship resilient, modular code at lightning speed.

Key Responsibilities

• Architect and develop end-to-end full-stack web and mobile applications using Next.js, React, Node.js, and TypeScript.
• Design highly scalable relational (PostgreSQL) and non-relational database schemas optimized for low latency and high concurrency.
• Build secure, performant REST and GraphQL APIs with robust authentication (OAuth, JWT) and rate-limiting protocols.
• Lead code reviews, enforce strict engineering standards, and mentor mid-level and junior developers across sprint cycles.
• Collaborate directly with product stakeholders to convert complex business requirements into crisp technical specifications.
• Implement automated testing pipelines (Jest, Playwright) and continuous integration/continuous deployment (CI/CD) workflows.
• Diagnose, debug, and eliminate performance bottlenecks across front-end rendering and back-end queries.

Requirements & Experience

• 5+ years of production experience building modern web applications with JavaScript/TypeScript ecosystems.
• Expert-level proficiency in React, Next.js (App Router, Server Actions, SSR/SSG), and Node.js.
• Strong understanding of database design, indexing strategies, and caching layers with Redis and PostgreSQL/MongoDB.
• Proven track record of deploying applications to AWS (ECS, Lambda, RDS) or Vercel with Docker containerization.
• Deep comprehension of web security best practices (CORS, CSRF, XSS, OWASP Top 10).
• Exceptional problem-solving abilities and clear technical communication skills in asynchronous remote setups.
