Job description

We are looking for an experienced Platform Architect to define and drive the architecture of a modern, cloud-native platform supporting scalable, secure, and resilient applications.

The role requires strong expertise in containerization, microservices, Kubernetes, cloud platforms, Redis, multi-tenant architecture, and cross-region deployment. Microsoft Azure experience is preferred.

The Platform Architect will work closely with engineering, DevOps/SRE, security, and product teams to establish platform standards, reference architectures, and reusable technical patterns.

Key Responsibilities

• Define the overall architecture and technical direction for the platform.
• Design scalable and resilient microservices-based architectures.
• Establish standards for containerized workloads and Kubernetes deployments.
• Define cloud architecture using Azure services and cloud-native design principles.
• Design secure and scalable multi-tenant architectures, including tenant isolation and resource segregation.
• Define multi-region deployment, failover, disaster recovery, and resilience strategies.
• Design caching and distributed state-management solutions using Redis.
• Establish standards for service communication, API design, asynchronous messaging, retries, resiliency, and fault handling.
• Define platform security patterns including identity, access control, secrets management, and workload isolation.
• Define observability standards for logs, metrics, traces, alerts, and service health.
• Guide Infrastructure-as-Code, CI/CD, and automated platform deployment practices.
• Conduct architecture and design reviews and drive resolution of architectural risks and technical debt.
• Create and maintain reference architectures, design documentation, and architecture decisions.
• Mentor engineering teams on cloud-native and distributed-system design practices.

Core Technical Skills

Must Have

Containerization

• Strong experience with Docker/OCI containers.
• Understanding of container lifecycle, security, networking, and image optimization.

Kubernetes

• Strong hands-on architectural knowledge of Kubernetes.
• Experience with:
  • Deployments, StatefulSets, Services, and Ingress
  • ConfigMaps and Secrets
  • Autoscaling and resource management
  • Persistent storage
  • RBAC and network policies
  • Cluster and workload high availability
• Experience with Azure Kubernetes Service (AKS) preferred.

Microservices & Distributed Systems

• Strong understanding of:
  • REST APIs and service-to-service communication
  • Event-driven and asynchronous architectures
  • API gateways
  • Service decomposition
  • Resiliency patterns
  • Distributed transactions
  • Eventual consistency
  • Idempotency
  • Fault tolerance and graceful degradation

Cloud Architecture

• Strong cloud architecture experience, preferably with Microsoft Azure.
• Familiarity with relevant Azure services such as:
  • AKS
  • Azure Container Registry
  • Azure Front Door / Application Gateway
  • Virtual Networks and Private Link
  • Microsoft Entra ID
  • Managed Identities
  • Key Vault
  • Azure Monitor / Application Insights
  • Azure Storage
  • Azure SQL or equivalent databases
  • Azure Service Bus / Event Hubs
  • Azure Managed Redis

Redis

• Experience designing Redis for:
  • Distributed caching
  • Session or transient state
  • High availability
  • Replication and clustering
  • Cache invalidation
  • Performance optimization

Multi-Tenant Architecture

• Experience designing SaaS or shared platforms with:
  • Tenant isolation
  • Identity and authorization boundaries
  • Data and resource segregation
  • Tenant provisioning
  • Noisy-neighbor mitigation
  • Tenant-level monitoring and configuration

Multi-Region Architecture

• Experience designing:
  • Regional deployment patterns
  • Active-active and active-passive architectures
  • Traffic routing
  • Disaster recovery
  • Regional failover
  • Data replication
  • RTO/RPO strategies

Preferred Skills

• Infrastructure as Code using Terraform or Bicep
• Azure DevOps or GitHub Actions
• Helm and GitOps
• Kafka, Azure Service Bus, or Event Hubs
• OpenTelemetry, Prometheus, and Grafana
• API Management and service mesh
• SQL and NoSQL databases
• Zero-trust and cloud security
• SRE and reliability engineering practices

Experience

• Typically 10+ years of software or platform engineering experience.
• At least 4–6 years of experience in cloud-native and distributed-system architecture.
• Proven experience architecting production platforms using Kubernetes and microservices.
• Experience designing highly available, scalable, and resilient systems.

Key Architecture Competencies

The candidate should be able to evaluate architectural trade-offs such as:

• Shared vs dedicated tenant infrastructure
• Shared Kubernetes clusters vs tenant-specific clusters
• Database-per-tenant vs shared database models
• Stateless vs stateful services
• Synchronous APIs vs asynchronous messaging
• Active-active vs active-passive regional deployments
• Managed cloud services vs self-managed components
• Security and isolation vs infrastructure cost
