Job Specifications
Position: TypeScript Architect (Backend)
Duration: Contract to Hire
Location: Denver CO (Hybrid)
Job Description:
Seeking a TypeScript Architect to join a small, agile engineering team and lead architectural decisions for high-scale backend systems.
The Role
The TypeScript Architect will design, optimize, and guide the technical architecture for highly scalable, event-driven backend systems. This includes real-time data pipelines, microservices, performance engineering, and cloud-native development.
Key Responsibilities
Architect scalable backend systems using TypeScript/Node.js and event-driven microservice patterns (Kafka, SNS/SQS, etc.).
Design and implement streaming and asynchronous processing pipelines for large-scale workloads.
Define and enforce DynamoDB data modeling, partitioning, and indexing strategies for high-write use cases.
Establish and optimize caching layers (Redis, Elasticache, DAX, in-memory caching) for high-performance APIs.
Perform full-stack profiling and performance tuning (CPU, memory, network, DB, I/O).
Define API contracts, message schemas (Avro/JSON), and versioning standards for inter-service communication.
Implement strong observability—metrics, tracing, structured logging—for performance monitoring.
Collaborate with DevOps on CI/CD pipelines, IaC (CloudFormation/Terraform), containerization, and autoscaling.
Mentor engineering teams on TypeScript best practices, async programming, and microservice resilience (circuit breaker, retry, backoff).
Partner with stakeholders to evolve architecture aligned with business growth and product roadmap.
What You’ll Bring
Strong expertise in TypeScript & Node.js, including async/await, streams, worker threads.
Deep knowledge of Kafka architecture & tuning (partitioning, consumer groups, rebalancing, offsets, schema evolution).
Strong experience with AWS DynamoDB: data modeling, GSIs/LSIs, TTL, streams, DAX, large-scale strategy.
Expertise with caching frameworks: Redis, Memcached, DAX, CDN/edge caching.
Strong skills in performance tuning & scalability: CPU profiling, async I/O optimization, load testing, connection pooling.
Experience designing REST and GraphQL APIs, including schema federation and gateway patterns.
Hands-on experience with monitoring tools like Datadog, Prometheus, CloudWatch, Splunk.
DevOps awareness: CI/CD (GitHub Actions, Jenkins), EKS/Kubernetes, Infrastructure-as-Code.
