Back End Developer

Job Title: Backend Engineer

Company: Growhut Technologies Private Limited

Salary: CTC (8.4 - 9.6 LPA)

Location: Remote

Employment Type: Full-time

Growhut Technologies Pvt Ltd is a forward-thinking company committed to delivering innovative web applications and scalable solutions. We are looking for a talented Backend Engineer to join our development team and contribute to building robust, high-performance backend systems.

We're hiring a Backend Developer (SDE II) to design and build scalable backend services for real-time applications. You'll work on APIs, WebSocket-based systems, media/RTC integrations, databases, caching layers, and cloud infrastructure. This role expects solid ownership - writing production-grade code, reviewing PRs, improving CI/CD, and debugging live issues on Linux/AWS.

• Design, develop, and maintain backend services using Node.js for high-scale, production systems.
• 
  
• Build and optimize real-time communication services using WebSockets and support workflows involving WebRTC.
• 
  
• Develop secure, well-documented REST/GraphQL APIs (as applicable), including authentication and role-based access.
• 
  
• Work with MySQL and MongoDB for data modeling, query optimization, indexing, and performance tuning.
• 
  
• Implement caching, queues, and pub/sub patterns using Redis to improve performance and responsiveness.
• 
  
• Containerize services using Docker, and ensure smooth local + production environments.
• 
  
• Design and maintain CI/CD pipelines using GitHub Actions, including build, test, lint, deploy, and rollback strategies.
• 
  
• Deploy and maintain services on AWS (EC2, S3), including logging, monitoring, and cost/performance optimizations.
• 
  
• Configure and troubleshoot NGINX for reverse proxying, load balancing, and SSL/TLS setup.
• 
  
• Own production stability: debugging, RCA, performance profiling, and incident resolution on Linux (Ubuntu).
• 
  
• Collaborate closely with frontend teams; contribute when needed in ReactJS for integration, debugging, and feature delivery.
• 
  
• Work on performance-sensitive modules or integrations where required using C++ (e.g., native modules, media/audio, system-level integration).
• 
  
• Write clean code, enforce best practices, and mentor junior engineers through reviews and technical guidance.

Must-have

• 36 years of backend development experience (or equivalent strong experience).
• 
  
• Strong proficiency in Node.js (architecture, async patterns, performance, scalability).
• 
  
• Hands-on experience with WebSockets and understanding of WebRTC fundamentals (signaling, STUN/TURN basics, real-time constraints).
• 
  
• Strong working knowledge of Linux (Ubuntu) and production debugging.
• 
  
• Experience with databases:
• 
  
• MySQL (schema design, joins, indexes, query tuning)
• 
  
• MongoDB (schema patterns, aggregation basics, indexing)
• 
  
• Practical experience with Redis (caching patterns, TTLs, pub/sub, rate limiting).
• 
  
• Experience deploying services on AWS EC2 + S3.
• 
  
• Solid understanding of Docker and container-based development workflows.
• 
  
• Experience designing CI/CD pipelines using GitHub Actions.
• 
  
• Hands-on experience with NGINX configuration for backend services.

Good-to-have

• Basic Python (scripts, tooling, small services, automation).
• 
  
• C++ exposure (native extensions, performance modules, system-level integration).
• 
  
• Familiarity with ReactJS for supporting frontend integration and debugging.
• 
  
• Experience with observability tools (logs, metrics, tracing), and performance profiling.

Soft skills

• Strong ownership mindset: you take features from design production monitoring.
• 
  
• Ability to communicate trade-offs clearly and work cross-functionally.
• 
  
• Bias for action with high engineering standards.

• Opportunity to work on real-time systems (WebSockets/WebRTC) and modern backend architecture.
• 
  
• High ownership role with end-to-end impact on product and infrastructure.
• 
  
• Collaborative team culture with strong engineering practices and code reviews.
• 
  
• Flexible work environment (depending on company policy).
• 
  
• Competitive compensation (based on experience) + performance growth opportunities.
• 
  
• Exposure to cloud scale, CI/CD maturity, and production-grade systems.
