Location: Dallas, TX (Onsite)

6 Months

Need visa H1B and H4 EAD & GC

Looking for 12 years

Key Responsibilities:

1. Lead Node.js API Development:

◦ Design, implement, and optimize scalable RESTful APIs using Node.js and Express.js (or similar frameworks).

◦ Architect API systems for maximum scalability, resilience, and performance.

◦ Ensure that APIs are modular, reusable, and easy to maintain.

◦ Integrate with third-party services, databases, and other internal systems.

2. Resilience Engineering:

◦ Apply principles of resilience engineering to design APIs that gracefully handle failures and continue to perform under stress.

◦ Implement retry logic, circuit breakers, and rate-limiting to ensure the APIs can withstand transient failures.

◦ Use techniques such as load balancing, failover mechanisms, and distributed architectures to improve fault tolerance.

3. Monitoring & Observability:

◦ Set up and maintain real-time monitoring and alerting using tools like Prometheus, Grafana, ELK stack, Datadog, or New Relic.

◦ Ensure comprehensive logging, tracing, and metrics collection (e.g., through Open Telemetry, Jaeger, or Zipkin) to provide visibility into system health.

◦ Proactively identify bottlenecks or performance issues and implement optimizations.

◦ Collaborate with the DevOps team to ensure system health and visibility across all environments.

4. API Security:

◦ Implement security best practices for API development (e.g., OAuth2, JWT tokens, rate limiting, IP whitelisting, and API gateways).

◦ Regularly perform code reviews and audits to ensure security vulnerabilities are mitigated.

5. Team Leadership & Collaboration:

◦ Lead and mentor a team of Node.js developers, providing technical guidance, code reviews, and career development.

◦ Drive adoption of best practices in API development, monitoring, and resilience across the team.

◦ Collaborate with cross-functional teams including front-end developers, DevOps, and QA to deliver high-quality software.

◦ Participate in sprint planning, backlog grooming, and retrospectives to ensure the team is aligned and focused on the right goals.

6. Continuous Improvement:

◦ Evaluate and recommend new technologies, tools, and frameworks that can improve development efficiency, monitoring capabilities, or resilience.

◦ Foster a culture of continuous learning and improvement within the development team.

◦ Ensure the team adopts DevOps practices and that software is fully automated for CI/CD pipelines.

Skills & Qualifications:

* Essential:

◦ 5+ years of experience in Node.js development, with at least 2+ years of experience in a leadership role.

◦ Strong expertise in designing and building RESTful APIs using Node.js.

◦ Experience in building highly available, fault-tolerant systems that can handle production-level traffic.

◦ Proficiency in monitoring and observability tools (e.g., Prometheus, Grafana, ELK stack, Datadog, New Relic).

◦ Experience with resilience patterns such as circuit breakers, retry logic, and rate limiting.

◦ Deep understanding of API security best practices (OAuth2, JWT, API Gateways, etc.).

◦ Experience with cloud platforms (AWS, GCP, Azure) and serverless architectures.

◦ Familiarity with CI/CD pipelines and tools (Jenkins, GitLab, CircleCI, etc.).

◦ Excellent problem-solving skills and the ability to troubleshoot complex distributed systems.

◦ Strong communication skills and the ability to collaborate effectively with cross-functional teams.

* Desirable:

◦ Experience with containerization and orchestration tools like Docker and Kubernetes.

◦ Familiarity with microservices architecture and event-driven systems.

◦ Experience working with NoSQL and relational databases (MongoDB, PostgreSQL, MySQL, etc.).

◦ Knowledge of automated testing and frameworks for Node.js (Mocha, Chai, Jest).

◦ Familiarity with Infrastructure as Code (e.g., Terraform, CloudFormation).

◦ Knowledge of distributed tracing and service meshes (e.g., Istio, Linkerd).
