TypeScript Architect

Position

Stefanini Group is seeking a Type Script Architect – Dev Ops Engineer in Denver, CO. The role is full‑time, 12‑month assignment.

• Architect scalable backend systems using Type Script/Node.js and event‑driven patterns (Kafka, SNS/SQS, etc.).
• 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 Dev Ops to ensure CI/CD pipelines, IaC (Cloud Formation/Terraform), and autoscaling policies support architectural goals.
• Mentor engineering teams on Type Script 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.

• Strong expertise in Type Script & 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, Cloud Watch, or Splunk.
• Dev Ops awareness: CI/CD (Git Hub Actions, Jenkins), container orchestration (EKS/Kubernetes), and IaC tools.

Pay range: $60.00–$62.00 per hour.
