Looking for a Typescript Architect to work in a small, agile team.
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.

Requirements

• 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.

Responsibilities

• 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.

Benefits

• We help take care of your today and tomorrow with industry-leading benefits, support, and services that look after your holistic health and wellbeing.
• We’re also champions of life balance and offer flexible arrangements that work for you (role and location dependent).
• We’re always looking for new ways of working that bring out our best, which leads to unexpected ideas.
• So here, you’ll experience a sense of belonging, and discover autonomy, freedom, and ownership as you work alongside talented people you enjoy sharing knowledge with.
