JR-215582 Javascript Developer Senior

Hello, our name is Customertimes, but you can call us CT. We are a global digital engineering, product development, and technology consulting company. Headquartered in New York, we have a team of 1000+ experts working across 65+ countries.

About this job:

You design and build the services and data layer that power the platform, with a focus on reliability, performance, and clean API design. This scope may alternatively be covered by two full-stack engineers who together cover the backend stack and contribute to the React frontend.

How you'll make an impact:

• Build and maintain backend services with NestJS and TypeScript;
• Design and implement GraphQL schemas, resolvers, and data loaders; manage schema evolution;
• Use Redis for caching, session handling, rate limiting, and queues/pub-sub as appropriate;
• Integrate with Snowflake: design queries, manage data access patterns, and optimize cost and performance;
• Implement authentication, authorization, and input validation in line with the security architecture;
• Write automated tests (unit, integration, contract) and maintain high code quality;
• Instrument services with logging, metrics, and tracing; support production troubleshooting;
• Collaborate with the Solution Architect, frontend, QA, and DevOps teams.

What makes you a great fit:

• 5+ years of backend development; 3+ years with Node.js/NestJS and TypeScript;
• Strong experience building GraphQL APIs in production;
• Hands-on experience with Redis and caching strategies;
• Experience with Snowflake or another cloud data warehouse, with strong SQL skills;
• Understanding of API security, performance tuning, and scalable design patterns;
• Experience with Docker and CI/CD workflows.

You are a star if you have:

• Experience with event-driven architectures and message queues;
• Experience with GraphQL federation or subscriptions;
• Familiarity with data modeling and ELT pipelines (e.g., dbt).

If hiring two full-stack engineers instead:

Each should combine the backend requirements above (NestJS, GraphQL, SQL/data access) with solid React and TypeScript experience, and be comfortable owning features end to end, from UI to data layer.

If you're looking to contribute to global projects, grow your skills, shape the way you work, and be part of a connected international community — Customertimes is the place to build your next career chapter. Are you ready to spark the tech with us?
