Commission Backend Engineer Jobs (NOW HIRING)

RESPONSIBILITIES:
Kforce has a client that is seeking a Senior Backend Engineer (TypeScript/Node.js) in Greenwood Village, CO.
About the Role:
We are looking for a senior engineer who doesn't just write code - they own outcomes. You will be responsible for the full lifecycle of backend services: from design and development through production reliability. In an era where AI can generate code, we value engineers who think critically, anticipate problems, and drive systems forward.
What We Expect:
End-to-End Ownership:
* Own features from design -> development -> testing -> deployment -> production support
* Take accountability for the reliability and performance of your services in production
* Drive technical decisions without waiting to be told what to do
System Design & Architecture:
* Design scalable, resilient distributed systems handling millions of daily transactions
* Make pragmatic trade-off decisions (consistency vs. availability, complexity vs. speed)
* Produce clear technical design documents and lead design reviews
* Evaluate build vs. buy decisions with data
Development:
* Build high-throughput, low-latency microservices using frameworks like NestJS, Express, or Fastify
* Write clean, type-safe, maintainable code - but more importantly, know when and what to build
Testing & Quality:
* Write meaningful unit, integration, and contract tests - not just for coverage metrics
* Own E2E test strategy for your services
* Build confidence in deployments through automated validation
Infrastructure & Cloud (AWS):
* Hands-on with AWS services (ECS/EKS, Lambda, S3, SQS, CloudWatch, IAM)
* Understand networking, security, and cost implications of architectural choices
* Comfortable with Infrastructure as Code (Terraform/CloudFormation)
Data & Messaging:
* Kafka - design event-driven architectures, manage topics, handle consumer lag and rebalancing
* Redis - caching strategies, pub/sub, cluster management
REQUIREMENTS:
* 8+ years of experience
* Strong proficiency in TypeScript and Node.js
Nice to Have:
* Experience with circuit breaker patterns (opossum, cockatiel)
* Performance tuning at scale (Node.js event loop, worker threads, connection pools)
* Experience with CI/CD pipelines and deployment strategies (blue-green, canary)
* Contributions to internal tooling or developer experience improvements
* Experience leading technical initiatives across multiple teams
