Enterprise Architect

Tiger Analytics; Chennai District; On-site; INR 3,500,000 - 7,500,000; Full time

Job summary

Tiger Analytics in Chennai, India is seeking a senior enterprise architect to lead cloud modernization across GCP, AWS, and Azure. You will design target infrastructures, security perimeters, and governance frameworks to enable scalable, reliable platforms.

The role requires hands-on architectural leadership, TOGAF-expertise, and the ability to drive zero-downtime cutovers using modern CI/CD pipelines and GitOps practices.

Qualifications

• 15+ years in engineering leadership and enterprise architecture.
• Expertise in multi-cloud migrations with rapid troubleshooting during cutovers.
• Mastery of GCP security constructs with hands-on remediation.
• Proven ability to reverse-engineer legacy architectures into high-availability designs.
• TOGAF / Domain-Driven Design proficiency is a plus.

Responsibilities

• Drive end-to-end GCP target infrastructure design for multi-cloud migrations — hybrid networking, IAM, storage, and security perimeters.
• Own GCP security architecture (GKE, IAM, VPC Service Controls, Security Command Center) and lead hands-on vulnerability remediation.
• Set enterprise blueprints and governance using TOGAF principles; chair ADR boards and run DAR trade-off evaluations vs. AWS/Azure.
• Map legacy AWS/Azure architectures and re-platform them onto scalable, fault-tolerant GCP topologies.
• Architect ultra-low-latency, high-concurrency transactional platforms with sub-second, edge-to-cloud performance.
• Design zero-downtime cutovers — shadow traffic, dual-write sync, automated rollback — and touchless GitOps deployments.
• Architect resilient microservices/microfrontends with sidecar patterns (Istio) and BFF-driven Web (React.js) and Mobile (Kotlin) platforms.
• Lead Kafka/Redis/Valkey streaming & caching architecture and full-stack data observability via Datadog.
• Embed AI coding assistants (Cursor, Copilot) into the SDLC and present architecture decisions to C-level stakeholders.

• Set enterprise blueprints and governance using TOGAF principles; chair ADR boards and run DAR trade-off evaluations vs. AWS/Azure.
• Map legacy AWS/Azure architectures and re-platform them onto scalable, fault-tolerant GCP topologies.
• Architect ultra-low-latency, high-concurrency transactional platforms with sub-second, edge-to-cloud performance.
• Design zero-downtime cutovers — shadow traffic, dual-write sync, automated rollback — and touchless GitOps deployments (ADO + ArgoCD).
• Architect resilient microservices/microfrontends with sidecar patterns (Istio) and BFF-driven Web (React.js) and Mobile (Kotlin) platforms.
• Lead Kafka/Redis/Valkey streaming & caching architecture and full-stack data observability via Datadog.
• Embed AI coding assistants (Cursor, Copilot) into the SDLC and present architecture decisions to C-level stakeholders.

• Proven ability to reverse-engineer legacy AWS/Azure architectures into high-availability GCP target designs.
• Track record designing mission-critical, real-time, high-concurrency transactional or event-driven systems.
• Proven zero-downtime cutover execution — canary testing, dual-write sync, touchless deployments, automated rollback.
• Practical mastery of TOGAF / Domain-Driven Design for large-scale platform modernization (TOGAF certification a plus).
• Demonstrated microservices, microfrontend, and sidecar pattern expertise.
• Proven Web and Mobile architecture experience, including Kotlin exposure and mobile security.
• Extensive Kafka streaming and Redis/Valkey caching architecture experience.
• Proven leadership of ADR boards and structured DAR evaluations against AWS/Azure.
