India Remote Department: Software Engineering / Architecture Role OverviewWe are seeking a hands-on Application / Development Architect with 5 to 7 years of relevant experience to spearhead the modernization of legacy enterprise systems. In this role, you will lead technical roadmaps to refactor and migrate mission-critical legacy .
NET Framework applications to modern .
NET 10 microservices and distributed workloads. You will design containerized runtimes on Linux, orchestrate workloads using Amazon EKS, implement event-driven and compute pipelines using AWS Lambda and AWS Batch, and establish robust automated CI/CD delivery workflows. The ideal candidate combines hands-on engineering depth with architectural leadership to design scalable, secure, and cost-effective cloud-native architectures.

Key Responsibilities
Architectural Strategy & Modernization
• Architect and execute application modernization strategies to transition legacy monolithic .
NET Framework applications (4.x/WCF/ASMX/ASP.
NET MVC) to modern .
NET 10 cross-platform architectures.
• Redesign monolithic systems into modular, API-first microservices, distributed batch jobs, and event-driven patterns.
• Conduct code-level architectural assessments, evaluate dependencies/NuGet compatibility, establish migration wave plans, and remove platform-specific constraints (e.g., Windows registry, GAC, machine-specific COM interop). Containerization & Cloud Native Architecture (AWS)
• Containerize .
NET services using Docker running on lightweight, hardened Linux base images (e.g., Alpine/Chiseled images).
• Design and implement high-availability container orchestration solutions using Amazon EKS (Kubernetes), including ingress routing,



service mesh integration, HPA (Horizontal Pod Autoscaling), and cluster resource management.
• Architect compute-specific workloads across AWS Batch (for high-throughput batch and data processing jobs) and AWS Lambda (for serverless, event-driven components).
• Integrate core AWS cloud services (Amazon SQS/SNS, DynamoDB, Amazon Aurora/RDS, EventBridge, IAM Roles for Service Accounts
- IRSA). CI/CD, DevOps & Automation
• Design and maintain end-to-end continuous integration and continuous deployment (CI/CD) pipelines using GitHub Actions, GitLab CI, or AWS CodePipeline/ArgoCD.
• Enforce automated quality gates: static code analysis (SonarQube), container security/vulnerability scanning (Trivy, Amazon ECR scanning), unit/integration testing baselines, and deployment verification.
• Promote Infrastructure as Code (IaC) standards utilizing Terraform or AWS CDK. Technical Leadership & Governance
• Establish best practices around cross-platform .
NET development, asynchronous programming, observability (OpenTelemetry, AWS CloudWatch, X-Ray), and Zero-Trust cloud security.
• Mentor development squads, conduct architectural spike reviews, and author Architecture Decision Records (ADRs).
• Collaborate with product owners, enterprise architects, and site reliability engineers (SRE) to ensure compliance with enterprise SLAs, RTO/RPO objectives, and FinOps benchmarks. Required Qualifications & Technical Skills
•

Experience:

• Core .
NET Expertise:
• Deep proficiency in C# and the .
NET ecosystem (.
NET Framework 4.x and modern .
NET Core / .
NET 8 / .
NET 10).
• Proven track record of refactoring legacy components: replacing WCF/Remoting with gRPC or RESTful APIs, migrating Entity Framework to EF Core, and updating configuration management.
• Linux & Containers:
• Extensive hands-on experience packaging, optimizing, and debugging .
NET applications on Linux-based Docker containers.
• Production experience with Amazon EKS / Kubernetes (Deployments, Services, ConfigMaps, Secrets, Ingress, Pod Identity/IRSA).
• AWS Serverless & Compute Services:
• Strong working knowledge of designing workloads with AWS Lambda and orchestrating large-scale computational or scheduled processing using AWS Batch.
• DevOps & Delivery:
• Strong experience engineering production-grade CI/CD pipelines for automated build, test, container image packaging, and progressive cluster deployment (Blue/Green, Canary).
• Fundamentals:
• Solid mastery of Object-Oriented Design, Microservices Design Patterns, Domain-Driven Design (DDD), Distributed Caching, and REST/gRPC API standards. Preferred / Nice-to-Have Skills
• Experience with contemporary .
NET distributed application orchestration frameworks such as .
NET Aspire.
• Familiarity with GitOps paradigms using ArgoCD or Flux on Kubernetes.
• AWS Certified Solutions Architect – Associate/Professional or AWS Certified DevOps Engineer.
• Familiarity with Infrastructure as Code using Terraform or AWS CDK.
• Exposure to database migration strategies (SQL Server modernization to PostgreSQL/Amazon Aurora).
