Application Architect

Job Description – Application Architect (Microservices | Node.js | Nest.js | Flutter | Cloud-Native) Location: Pune or Mumbai (Hybrid) Experience: 10–15 years Role: Application Architect / Senior Application Architect Domain Advantage: BFSI / Insurance / Payments About the Role You will serve as the Application Architect for enterprise-scale digital platforms built using Node.js , Nest.js , microservices , and Flutter for mobile applications. The role demands architectural leadership across backend services, mobile front-end architecture, and cloud-native deployments. 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.
