We are seeking a highly skilled Senior Engineer with deep expertise in Kubernetes, Istio, and Node.js to join our engineering team. The ideal candidate will be responsible for designing, implementing, and optimizing cloud-native microservices architectures with a strong focus on scalability, reliability, and security. You will collaborate with cross-functional teams, including DevOps, architects, and application developers, to ensure seamless service delivery, traffic management, and observability.

This role requires a balance of hands-on coding, infrastructure engineering, and system design, making it ideal for a senior professional who thrives in dynamic, fast-paced environments.

Key Responsibilities

Kubernetes & Istio

Design, deploy, and manage Kubernetes clusters for production-grade workloads.
Implement and optimize Istio service mesh for traffic routing, canary deployments, service discovery, and secure inter-service communication.
Define and manage multi-tenant, multi-cluster strategies ensuring reliability and scalability.
Enable observability with Prometheus, Grafana, Kiali, and Jaeger for metrics, tracing, and monitoring.

Node.js Development

Architect and develop scalable backend microservices using Node.js/TypeScript.
Implement RESTful APIs and GraphQL endpoints with strong focus on performance and resilience.
Apply best practices in asynchronous programming, event-driven architectures, and API security.
Integrate with databases (SQL/NoSQL), caching layers, and external services.

Cloud & DevOps

Collaborate with DevOps to build CI/CD pipelines (GitHub Actions, Jenkins, or ArgoCD) for automated deployments.
Ensure infrastructure-as-code (IaC) practices using tools such as Terraform or Helm.
Optimize system performance, cost, and scalability across AWS/GCP/Azure.
Troubleshoot production issues, conduct root-cause analysis, and drive continuous improvements.

Collaboration & Leadership

Mentor junior engineers, perform code reviews, and ensure adherence to coding standards.
Partner with architects to define technical roadmaps and system designs.
Communicate technical solutions effectively to both technical and non-technical stakeholders.

Required Qualifications

Bachelor’s or Master’s in Computer Science, Engineering, or related field (or equivalent experience).
6–10 years of professional engineering experience, with at least 3+ years in Kubernetes and service mesh (Istio/Linkerd/Consul Connect).
Proven expertise in Node.js/TypeScript, with strong understanding of asynchronous programming, API design, and performance tuning.
Deep understanding of containerization (Docker), Kubernetes architecture, networking, and Istio traffic management.
Hands-on experience with microservices design patterns, distributed systems, and event-driven systems (Kafka, RabbitMQ, or NATS).
Strong knowledge of CI/CD pipelines, infrastructure-as-code, and cloud-native best practices.
Experience with monitoring, logging, and tracing tools (Prometheus, Grafana, ELK, Jaeger, Datadog).
Excellent problem-solving, debugging, and communication skills.

Preferred Qualifications

Certifications: CKA/CKS (Certified Kubernetes Administrator/Security Specialist), Istio Certified Practitioner, or equivalent.
Experience with service-to-service security (mTLS, JWT, OAuth2, OPA/Envoy filters).
Knowledge of GraphQL, gRPC, or API Gateway (Kong, Ambassador, Apigee).
Prior experience in multi-cloud or hybrid cloud architectures.
Exposure to AI/ML pipelines or real-time streaming architectures is a plus.
