About Customertimes:
Customertimes (CT) is 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 will 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.
