Senior Node JS Engineer

Company Overview
Jetbro is a trusted technology partner for enterprises where reliability isn't optional. We build and integrate mission-critical systems that power operations across Fortune 500 companies and fast-scaling disruptors globally. Our philosophy is simple: Function over flash. Always. We believe in quiet engineering that works reliably at scale, without unnecessary complexity. Our diverse team spans technology consulting, engineering, data, cloud, and AI capabilities. We don't chase trends; we engineer solutions built for longevity, clarity, and real-world impact. We are the partner of choice when technology must deliver with reliability and scale, executing projects across geographies and industries including enterprise software, digital consumer tools, supply chains, healthcare, energy, and education.
About the Role
We are seeking an experienced Node.js Developer to join our engineering team and contribute to building scalable, mission-critical backend systems for one of our enterprise clients. You will work in a fast-paced environment where your code directly impacts how millions of users interact with our client's platform.

In this full-time role, you will translate business requirements and design specifications into robust, production-ready Node.js applications. You'll collaborate closely with product managers, designers, and fellow engineers to build features that are not only technically sound but also user-centric. Your work will span microservices architecture, database optimisation, third-party API integrations, and payment gateway implementations. You'll be expected to work from detailed Business Requirements Documents (BRDs) and design specifications, translating them into elegant backend solutions.

You'll be part of a team that values reliability, scalability, and clean code where every line of code you write is expected to perform flawlessly in production environments.
Key Responsibilities

• Design and develop scalable Node.js backend services and microservices that handle high-volume transactional workloads
  
• Implement RESTful APIs and integrate third-party services including payment gateways, WhatsApp Business APIs, and external data sources
  
• Work with distributed databases including CockroachDB, Redis, and Cassandra to optimise data storage, retrieval, and caching strategies
  
• Build event-driven workflows and automated processes that guide customers through complex business journeys
  
• Translate Business Requirements Documents (BRDs) and Figma design specifications into technical implementations
  
• Collaborate with frontend engineers to ensure seamless API contracts and optimal performance
  
• Implement and maintain comprehensive logging, monitoring, and error tracking across all services
  
• Conduct code reviews and mentor junior developers, ensuring adherence to coding standards and best practices
  
• Optimise application performance, identify bottlenecks, and implement solutions for improved scalability
  
• Participate in architectural discussions and contribute to technical decision-making
  
• Ensure data security, compliance, and proper handling of sensitive information including payment data
  
• Troubleshoot production issues, perform root cause analysis, and implement preventative measures
  
• Write clean, maintainable, and well-documented code following SOLID principles
  
• Collaborate with DevOps and infrastructure teams to ensure smooth deployment and monitoring
  
  

Requirements

Mandatory Requirements

• 4–5 years of professional experience developing production-grade applications with Node.js
  
• Strong proficiency in asynchronous programming, event-driven architecture, and callback/promise/async-await patterns
  
• Proven experience designing and implementing microservices architecture at scale
  
• Hands-on experience with at least one distributed database system (CockroachDB, Cassandra, or similar)
  
• Demonstrated expertise with Redis or similar in-memory caching solutions
  
• Experience integrating third-party APIs and payment gateways (Stripe, Razorpay, PayPal, etc.)
  
• Solid understanding of RESTful API design principles and best practices
  
• Proficiency with version control systems (Git) and collaborative development workflows
  
• Experience working with BRDs (Business Requirements Documents) and translating them into technical specifications
  
• Ability to read and interpret design specifications from Figma or similar design tools
  
• Strong problem-solving skills and ability to debug complex issues in production environments
  
• Experience with SQL and NoSQL databases; understanding of database optimisation and query performance
  
• Familiarity with containerisation technologies (Docker) and basic DevOps concepts
  
• Excellent communication skills and ability to work effectively in cross-functional teams
  

Good To Have

• Experience with message queues (RabbitMQ, Kafka, or similar) for asynchronous processing
  
• Knowledge of GraphQL and experience building GraphQL APIs
  
• Experience with WhatsApp Business API or similar messaging platform integrations
  
• Familiarity with cloud platforms (AWS, GCP, or Azure) and serverless architectures
  
• Experience with automated testing frameworks and test-driven development (TDD)
  
• Contribution to open-source projects or a public GitHub portfolio demonstrating your work
  
• Experience with CI/CD pipelines and deployment automation
  
• Understanding of security best practices including authentication, authorisation, and data encryption
  

What we care about

• Reliability First: We build systems that cannot fail. Your code should be production-ready, thoroughly tested, and resilient to edge cases.
  
• Function Over Flash: We value practical, elegant solutions over complex or trendy approaches. Simplicity and clarity matter more than cleverness.
  
• Ownership and Accountability: We expect you to take full ownership of your work, from design through deployment and maintenance.
  
• Continuous Learning: Technology evolves rapidly. We value engineers who stay curious, learn from failures, and continuously improve their craft.
  
• Collaboration and Communication: You'll work closely with designers, product managers, and fellow engineers. Clear communication and teamwork are essential.
  
• Scalability Mindset: Every decision you make should consider how the system will perform at 10x, 100x, or 1000x current scale.
  
• Customer-Centric Thinking: Understand how your backend work impacts the end user experience and business outcomes.
  

About You
You are an experienced Node.js developer with a proven track record of building scalable, reliable backend systems.
