Looking for Senior Nodejs Developer

Experience: 5 to 7 years

Location: Hyderabad

Employment Type: Contract to Hire

Notice Period: Immediate to 7 days Maximum

Must Skills: Node.js / JavaScript (Expert) / Typescript / Fast API

JD:

We are looking for a backend engineer who actually understands how money flows through software, not just how to write endpoints. You’ll build and maintain systems that power Quote-to-Cash (Q2C) workflows, including pricing, subscriptions, invoicing, and lifecycle state management. This is not a CRUD-only role.

If you’ve never dealt with subscription pricing models, idempotency, state transitions, or performance at scale, this role will expose that gap quickly.

Job Description:

Backend Development

• Design and implement backend services for Quote → Order → Subscription → Invoice → Payment flows
• Build high-performance APIs using REST and WebSockets where real-time updates matter
• Implement Redis-based caching strategies to reduce latency and DB load (no blind caching)
• Design and optimize SQL/PostgreSQL schemas with proper indexing, constraints, and migrations

Subscription & Pricing Logic

• Implement and maintain subscription pricing models (tiered, usage-based, prorations, renewals)
• Handle pricing accuracy, edge cases, and lifecycle transitions without data corruption
• Ensure financial calculations are deterministic, auditable, and idempotent

Infrastructure & Reliability

• Containerize services using Docker and deploy on Kubernetes
• Integrate StatsD / monitoring to track performance, errors, and system health
• Understand and apply TCP/IP fundamentals when diagnosing latency or connection issues

Testing & Quality

• Write high-coverage unit and integration tests using Jest / Mocha
• Treat tests as non-negotiable, not optional documentation
• Enforce correctness in pricing, billing, and subscription logic through tests

Required Technical SkillsBackend & Data

• Strong experience with PostgreSQL / SQL (query optimization, transactions, locking)
• Hands-on experience with Redis for caching and performance optimization
• Clear understanding of data consistency vs performance tradeoffs

Networking & APIs

• Solid understanding of RESTful API design
• Experience with WebSockets for real-time communication
• Practical knowledge of TCP/IP fundamentals (timeouts, retries, connections)

Testing

• Proven experience with Jest and/or Mocha
• Ability to maintain high test coverage without slowing development

Infrastructure

• Real-world experience with Docker and Kubernetes
• Familiarity with monitoring and metrics (StatsD or similar tools)

Domain Experience (Strong Preference)

• Direct experience with Quote-to-Cash systems
• Hands-on work with subscription billing and pricing engines
• Understanding of SaaS monetization models and billing edge cases
