The role balances technical leadership with business and stakeholder engagement.Job Description:\nRequired Experience: 14-20 Years\nTeam Management- Yes\nKey Relationships: Product, Delivery, Architecture, Security, DevOps / SRE\nA senior role accountable for target architecture, engineering practices and delivery governance across a polyglot engineering platform spanning React, TypeScript, Node.js, NestJS, MongoDB/Mongoose, GraphQL Federation, Kafka, Python/FastAPI and n8n-based automation. You set target architecture and engineering standards, and stay close enough to the code to assure designs you approve. You own identity, data, event-driven and AI-assisted engineering architecture, translating strategy into a funded roadmap for the engineering team and its sub-pods.\nKey Responsibilities:\nDefine the target technical architecture for the platform, including architecture principles, reference patterns, and the roadmap from current to target state. \nGovern architecture decisions through documented decision records, design review, and conformance checkpoints, escalating material trade-offs for approval. \nArchitect the React/TypeScript frontend, covering component structure, state management, performance budgets, and accessibility standards. \nDirect backend service architecture in Node.js/TypeScript (NestJS), including service boundaries, API contracts, resilience patterns, and versioning strategy. \nDefine the data architecture across MongoDB, covering schema and access-pattern design, indexing strategy, data lifecycle, and integrity controls. \nOwn the GraphQL Federation architecture: supergraph composition, subgraph boundaries, schema contracts, entity resolution, and breaking-change policy. \nEstablish event-driven architecture on Kafka, defining topic and event contract design, partitioning, delivery semantics, and schema evolution rules. \nSet the identity and access architecture, covering authentication and authorization flows, token handling, session policy, and least-privilege service access. \nGuide the Python/FastAPI service architecture, defining where it is the correct tool, its contract and packaging conventions, and its integration with the wider platform. \nScope and constrain n8n usage to workflow automation and integration orchestration, defining the guardrails that distinguish automation workflows from engineered application services. \nOwn the AI architecture, covering model integration and routing, prompt and tooling boundaries, evaluation criteria, and safety and cost controls. \nAssure evidence-based application readiness for Docker and Kubernetes, ensuring applications correctly consume platform-owned Helm charts and GitHub Actions pipelines rather than duplicating them. \nSet runtime performance and observability standards, including Azure Cache for Redis caching patterns and Application Insights instrumentation, tracing, and alerting. \nPartner with the engineering team and its sub-pods to raise engineering practices, embed the testing strategy across unit, integration, contract, and end-to-end layers, and sustain predictable delivery flow.\nMust Have Skills:\nProven technical leadership of an engineering team at Lead Technical Architect or Principal Architect scope.\nDeep expertise in TypeScript, React, Node.js, NestJS, MongoDB/Mongoose and Web Components/micro-frontends.\nGraphQL schema design and federated graph architecture (GraphQL Federation), including subgraph composition and contract versioning.\nExperience with event-driven architecture using Kafka, Schema Registry and Avro, including schema evolution and compatibility governance.\nExperience with identity and access architecture: OAuth2/OIDC, Okta, service-account token exchange and ABAC.\nWorking knowledge of Python/FastAPI in a polyglot service environment.\nExperience integrating AI capabilities in production systems, including Azure OpenAI and Anthropic model routing, with attention to prompt governance, token-cost control and PII safeguards.\nStrategy and architecture governance in a cross-functional environment.\nCloud-native, distributed systems design with deployment readiness ownership for Docker/Kubernetes applications consuming platform-owned Helm/GitHub Actions.\nDemonstrable accountability for delivery, reliability and security outcomes.\nEstablished testing and quality practice across Jest, React Testing Library, Playwright and pytest.\nTrack record of establishing engineering practices and architecture governance that scale across a complex organization.\nStrongly Preferred / Nice to Have:\nTOGAF certification or equivalent structured architecture practice.\nKubernetes, Docker, Infrastructure as Code and DevSecOps experience beyond core application readiness.\nLegacy modernization and platform re-architecture at scale.\nPlatform engineering or SRE practice - service level objectives, observability and operational resilience beyond core responsibilities.\nPrior integration delivery against Media ocean Prisma or comparable media buying and finance platforms.\nMicrosoft Certified: Azure Solutions Architect Expert or equivalent AWS certification\nLocation:\nDGS India -
