• The 'Architect-Engineer' profile: design for scale, simplification, and observability.

Job description

• Migration Strategy: Lead the migration from legacy architectures (N-Tier, Monolithic, Mainframe) to modern cloud-native planes using strategies like the Strangler Fig Pattern.
• Complexity Reduction: Identify redundant systems and consolidate application footprints

through rigorous refactoring and simplification, turning "spaghetti code" into modular services.

• Legacy-to-Modern Bridging: Architect integration layers that allow legacy systems to coexist with modern microservices during long-term migration cycles.
• Full-Stack & Advanced Pattern Design
• Event-Driven & Streaming: Design high-throughput systems using asynchronous patterns, Event Sourcing, and CQRS. Implement streaming backbones (Kafka, Redpanda) for real-time data processing.
• Microservices & Serverless: Establish standardized chassis and sidecar patterns for microservices, ensuring consistency across security, logging, and service discovery.
• Low-Latency & HA: Architect for "five nines" (99.999%) availability using multi-region active-active setups, circuit breakers, and edge computing to minimize latency.
• Cloud-Native Leadership
• Platform Evolution: Leverage Kubernetes (K8s), Service Mesh (Istio/Linkerd), and Serverless (Lambda/Cloud Functions) to build portable, elastic applications.
• Twelve-Factor Principles: Enforce Twelve-Factor App methodologies across all new developments to ensure cloud-native compatibility.
• Innovation Lab: Lead POCs on emerging tech like WebAssembly (Wasm) or AI-assisted refactoring to accelerate the modernization timeline.
• Required Skills & Qualifications
• Experience
• 12+ years in Software/Enterprise Architecture; 5+ years leading large-scale modernization programs.
• Full-Stack Depth
• Mastery of Java/Spring Boot, Node.js, or Go, plus modern frontend frameworks (React/Vue).
• Hands-on expertise in AWS, Azure, or GCP with a focus on PaaS and Serverless offerings.
• Patterns
• Deep knowledge of Microservices, EDA, Domain-Driven Design (DDD), and API-First design.
• Infrastructure
• Proficiency in Terraform/Pulumi, Docker, and Kubernetes orchestration.
• Legacy Knowledge
• Familiarity with COBOL, SOAP, old-school RDBMS (Oracle/DB2), and Enterprise Service Bus (ESB) patterns.
• The "Architect-Engineer" Profile
• Design for Scale: You don't just build for today; you build for 100x traffic spikes.
• Simplification Obsessed: You believe that "the best code is no code" and constantly look for ways to delete or consolidate legacy modules.
• Operational Empathy: You design systems that are easy to monitor (Observability) and even easier to troubleshoot.
