Job description

Company Name: R Systems International

Job Role: Senior Full Stack Developer

Experience Required: 3 to 6 Years

Employment Type: Full-Time

Location: India

Work Mode: Remote / Hybrid (Based on Project Requirements)

Qualification: Bachelor's Degree in Computer Science, Information Technology, Engineering, or a related field

We are looking for a solid Senior Full Stack Developer with at least 3 years of experience to join our core engineering team. This isn't a role for someone who just wants to "complete tasks" or "close tickets." We need a candidate with a strong ownership mindset who can take a feature from an idea to production‑either by leading a small team or by building it solo.

If you are a "pro" at Node.js, Postgres, and React, and you're excited about the possibilities of Generative AI and Playwright automation, we want to talk to you.

Key Responsibilities :

• End-to-End Delivery : Take complete "ownership" of features. You should be able to handle everything from designing the Postgres schema to building the React frontend.
• GenAI & RAG : Build and scale features using LLMs (OpenAI, Anthropic, etc.). You will work on prompt engineering, LangChain/LangGraph flows, and integrating AI agents into our products.
• Browser Automation : Build robust, scalable automation scripts using Playwright. You should be comfortable handling complex flows, bypassing bot detection, and managing browser sessions.
• Backend Mastery : Architect high-performance services in Node.js. Use Redis effectively for caching, managing queues, and ensuring low latency.
• Technical Leadership : Lead by example. Conduct thorough code reviews, mentor juniors, and ensure the team follows best practices.
• Autonomy : You should be a "self-starter." We expect you to take a high-level requirement and deliver a production-ready feature with minimal hand-holding.

Technical Skills Required :

• Backend : 3+ years in Node.js (TypeScript experience is a big plus). Must understand the event loop, scalability, and secure API design.
• Frontend : Strong hands‑on experience with React.js and state management (Zustand/React Query).
• Database & Cache :
• PostgreSQL : Expert at writing optimized queries, handling migrations, and DB tuning.
• Redis : Practical experience with caching strategies, rate-limiting, and distributed locking.
• Automation : Deep expertise in Playwright (or Puppeteer) for both E2E testing and automation use‑cases.
• GenAI Tech Stack : Experience with OpenAI APIs, vector databases, and AI orchestration frameworks.
• DevOps : Basic knowledge of Docker and CI/CD pipelines (GitHub Actions/GitLab).

Who You Are :

• Experience : Minimum 3 years in a product-based startup or a fast‑paced environment.
• Problem Solver : You have a "can-do" attitude. When things break, you deep‑dive into the root cause and fix it for good.
• Clear Communicator : You can explain complex technical trade-offs to non-tech stakeholders without using unnecessary jargon.
• Tech Enthusiast : You keep yourself updated with the latest in the AI and JavaScript ecosystem.
