Responsibilities:

Develop performant web applications using with TypeScript and server-side rendering optimizations.
Build robust RESTful APIs using with efficient request handling.
Implement code splitting lazy loading and advanced optimization techniques for fast page loads.
Design reusable components with a performance-first mindset.
Design systems capable of handling 100 k concurrent users with minimal latency.
Implement horizontal scaling patterns and load distribution strategies.
Architect microservices with clear service boundaries and efficient inter-service communication.
Design fault-tolerant systems using circuit breakers and graceful degradation patterns.
Optimize MongoDB schemas and queries for high-throughput operations.
Implement strategic indexing and aggregation pipeline optimizations.
Design multi-level caching strategies using Redis for sub-millisecond data access.
Implement database connection pooling and query result caching.
Design asynchronous processing systems using message queues to decouple services.
Implement event-driven architecture for real-time data processing.
Build queue-based systems to handle traffic spikes and background jobs.
Optimize message throughput and processing latency.
Profile and optimize application bottlenecks using performance monitoring tools.
Implement efficient algorithms and data structures for high-frequency operations.
Design memory-efficient solutions and apply garbage collection optimizations.
Conduct load testing and capacity planning for traffic scaling.

Requirements:

5 years developing high-traffic web applications with modern JavaScript/TypeScript.
Expert proficiency in optimization (SSR SSG caching strategies).
Strong experience with performance-focused API development.
Production experience with MongoDB optimization and query performance tuning.
Hands-on Redis experience for caching session management and pub/sub patterns.
Experience with message queue systems (RabbitMQ Kafka AWS SQS or Google Pub/Sub).
Proven track record building systems handling 10M requests per day.
Deep understanding of distributed systems challenges and solutions.
Experience with database sharding replication and read/write splitting.
Knowledge of CDN integration and edge caching strategies.
Understanding of eventual consistency and CAP theorem implications.
Experience optimizing applications for sub-100 ms response times.
Knowledge of memory management and CPU optimization techniques.
Proficiency with performance profiling and bottleneck identification.
Experience with load testing tools and performance benchmarking.
Understanding of network optimization and connection management.

Advantages :

Experience with real-time features using WebSockets or Server-Sent Events.
Knowledge of additional high-performance databases (e.g. PostgreSQL Elasticsearch).
Familiarity with cloud-native services (AWS Lambda Google Cloud Functions Azure Functions).
Experience with A/B testing in high-traffic environments.
Background in data analytics and metrics-driven optimization.

Technical Challenges Youll Solve

Optimizing database operations to handle millions of concurrent reads with < 50 ms latency.
Implementing caching strategies that reduce database load by 90 %.
Building queue systems that process 100 k messages per minute reliably.
Designing APIs that maintain performance under extreme traffic spikes.
Creating real-time features that scale to millions of simultaneous connections.
