About the Role

Node.js

You will shape the engineering strategy, define modern patterns (DDD, event-driven, microservices), and guide teams across backend, mobile, DevOps, and cloud engineering. Strong understanding of distributed systems, API ecosystems, and scalable cloud-native workloads is essential.

Key Responsibilities

1. Architecture & Design

• Architect cloud-native, microservices-driven applications using

  Node.js

  and

  Nest.js

  .
• Define service decomposition, APIs, event flows, domain boundaries, and integration patterns.
• Architect and review

  Flutter-based mobile applications

  , ensuring performance, modularity, and maintainability.
• Create

  high-level and low-level architecture diagrams

  , ADRs, sequence diagrams, and reference blueprints.
• Promote

  Domain-Driven Design (DDD)

  , clean architecture, and API-first principles.
• Ensure seamless communication between mobile apps and backend services through REST, GraphQL, WebSockets, or Pub/Sub.

2. Cloud & Platform Engineering

• Architect workloads on

  Google Cloud Platform (GCP)

  using:

• GKE

  ,

  Cloud Run

  ,

  Pub/Sub

  ,

  Cloud SQL/Firestore

  ,

  Cloud Storage

  ,

  BigQuery

  ,

  IAM

  ,

  Secret Manager

• If certified on AWS/Azure, design equivalent multi-cloud solutions.
• Implement cloud-native principles: autoscaling, fault tolerance, load balancing, caching, and cost optimization.

3. Frontend & Mobile Architecture (Flutter)

• Lead the architecture for

  Flutter

  applications with structured state management (BLoC, Cubit, Riverpod, GetX).
• Define modular app structure, widget composition patterns, offline-first designs, and performance optimizations.
• Guide integration of mobile apps with backend microservices, authentication systems (OAuth2, JWT), and cloud services.
• Establish standards for component libraries, UI performance, and code quality.

4. Engineering Leadership

• Provide architectural guidance to backend engineers, Flutter developers, DevOps teams, and QA.
• Conduct architecture reviews, code reviews, threat modeling, and NFR validation.
• Mentor engineering leads on clean code, secure design, API patterns, and mobile architecture best practices.
• Introduce internal frameworks, accelerators, and reusable templates to increase productivity.

5. Non-Functional Architecture (NFRs)

• Architect for scalability, performance, resilience, observability, and high availability.
• Implement logging, tracing, monitoring using OpenTelemetry, Stackdriver, Prometheus/Grafana.
• Ensure platforms comply with security best practices (OAuth2, IAM, secrets management, API security, secure mobile development).
• Define caching, rate limiting, traffic shaping, retries, circuit-breaking patterns.

6. DevOps & CI/CD Automation

• Define automated CI/CD pipelines for Nest.js + Flutter deployments using Cloud Build, GitHub Actions, Jenkins, or ArgoCD.
• Drive GitOps, infrastructure-as-code (Terraform/Helm), and containerization best practices.
• Ensure consistent deployment strategies across environments (Dev → QA → UAT → Prod).

7. Stakeholder Management

• Work collaboratively with product, cloud, and engineering stakeholders.
• Convert business requirements into accurate architectural designs and implementation plans.
• Present architectural decisions and rationales to leadership and client stakeholders.
