Job Description:
TypeScript Architect with a strong background in event-driven microservices, real-time data pipelines (Kafka), and cloud-native application design. The ideal candidate will drive the technical architecture for scalable backend systems leveraging TypeScript/Node.js, DynamoDB, Kafka, and advanced caching and performance optimization strategies.
Description of Services:
- Architect scalable backend systems using TypeScript/Node.js and event-driven patterns (Kafka, SNS/SQS, or equivalent).
- Design and implement streaming and asynchronous processing pipelines for large-scale workloads.
- Define and enforce data modeling and partitioning strategies for DynamoDB to handle high-write workloads efficiently.
- Establish and optimize caching layers (Redis, Elasticache, DAX, or in-memory caching) for high-performance APIs.
- Perform profiling and performance tuning across the stack (CPU, memory, network, database, I/O).
- Define API contracts, message schemas (Avro/JSON), and versioning standards for inter-service communication.
- Implement observability practices—metrics, tracing, and structured logging—to proactively monitor performance bottlenecks.
- Collaborate with DevOps to ensure CI/CD pipelines, IaC (CloudFormation/Terraform), and autoscaling policies support architectural goals.
- Mentor engineering teams on TypeScript best practices, async programming, and microservice resilience patterns(circuit breaker, retry, backoff, etc.).
- Partner with stakeholders to evolve system architecture in alignment with business growth and product roadmaps.
Required Skills:
- Strong expertise in TypeScript & Node.js, including async/await, streams, and worker threads.
- Kafka architecture & tuning: partitioning, consumer groups, rebalancing, offset management, and schema evolution.
- AWS DynamoDB: data modeling, secondary indexes, TTL, streams, DAX, and best practices for large-scale design.
- Caching frameworks: Redis, Memcached, DAX, or CDN edge caching.
- Performance tuning & scalability: CPU profiling, async I/O optimization, connection pooling, and load testing.
- API design: REST and GraphQL, including schema federation and gateway design.
- Monitoring tools: Datadog, Prometheus, CloudWatch, or Splunk.
- DevOps awareness: CI/CD (GitHub Actions, Jenkins), container orchestration (EKS/Kubernetes), and IaC tools.
Deliverables:
- Process Flows
- Mentor and Knowledge transfer to client project team members
- Participate as primary, co and/or contributing author on any and all project deliverables associated with their assigned areas of responsibility
- Participate in data conversion and data maintenance
- Provide best practice and industry specific solutions
- Advise on and provide alternative (out of the box) solutions
- Provide thought leadership as well as hands on technical configuration/development as needed.
- Participate as a team member of the team
- Perform other duties as assigned.
