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.
• 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
• Resiliency patterns
• Distributed transactions
• Eventual consistency
• Idempotency
• Fault tolerance and graceful degradation
• Strong cloud architecture experience, preferably with Microsoft Azure.
• Familiarity with relevant Azure services such as:
• AKS
• Virtual Networks and Private Link
• Managed Identities
• Key Vault

Redis

• Distributed caching
• Session or transient state
• High availability
• Replication and clustering
• Cache invalidation
• Performance optimization
• Experience designing SaaS or shared platforms with:
• Tenant isolation
• Identity and authorization boundaries
• Data and resource segregation
• Tenant provisioning
• Tenant-level monitoring and configuration

Multi-Region Architecture

• Active-active and active-passive architectures
• Traffic routing
• Disaster recovery
• Regional failover
• Data replication
• RTO/RPO strategies

Preferred Skills

Experience in one or more of the following areas is desirable:

• Infrastructure as Code using Terraform or Bicep
• Azure DevOps or GitHub Actions
• Helm and GitOps
• 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.

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

• Shared vs dedicated tenant infrastructure
• Database-per-tenant vs shared database models
• Stateless vs stateful services
• Managed cloud services vs self-managed components
• Security and isolation vs infrastructure cost
