Job Description

Senior AWS Migration Engineer with .NET
Location: Hybrid onsite in NYC 3-4 x per week
Duration: 4 months initially, with potential for extension
Position Overview
We are seeking experienced, hands-on Senior AWS Migration Engineers to support a large-scale on-premises-to-AWS cloud migration initiative. Candidates must bring deep application engineering experience in either Java/Spring Boot or C#/.NET, combined with demonstrated experience personally delivering production AWS migrations.
This is not an architecture-only or management role. Candidates should be comfortable working directly with application code, AWS infrastructure, Infrastructure as Code, CI/CD pipelines, databases, containers, networking, security, monitoring, troubleshooting, and production cutovers.
Core Qualifications
  • Strong hands-on experience delivering on-premises-to-AWS application migrations
  • Deep development expertise in either:
    • Java: Java, Spring Boot, APIs/microservices, JVM/runtime concepts
    • .NET: C#, .NET/.NET Core, Core and legacy .NET Framework modernization
  • Strong hands-on AWS engineering experience
  • Experience designing and implementing Infrastructure as Code (IaC)
  • Strong experience with CI/CD pipelines and automated deployments
  • Experience with relational databases and cloud database/data migration
  • Hands-on experience with containers and cloud compute platforms
  • Understanding of AWS networking, connectivity and IAM
  • Experience implementing cloud security controls, encryption, secrets management and least-privilege access
  • Experience with logging, monitoring, observability and production troubleshooting
  • Ability to plan and execute production cutover, rollback and validation strategies
  • Ability to work hands-on across application, infrastructure, database and deployment layers
  • AWS certifications are a plus, but hands-on migration depth is more important than certifications
.NET Profile
Candidates submitted for the .NET track should have strong hands-on experience with:
  • C#
  • .NET / .NET Core
  • Core
  • Legacy .NET Framework modernization
  • Windows-based application migration to AWS/cloud environments
  • APIs and distributed application architectures
  • Containerization
  • AWS application hosting and migration
  • Modern CI/CD and Infrastructure as Code
AWS Migration Experience
Candidates must be able to discuss at least two hands-on on-premises-to-AWS migrations they personally supported or delivered, including:
  • Starting/on-premises architecture
  • Target AWS architecture
  • Migration strategy and approach
  • Candidate's specific hands-on responsibilities
  • AWS services utilized
  • Application and database migration approach
  • Connectivity and IAM considerations
  • Infrastructure as Code and deployment strategy
  • Testing and validation
  • Production cutover and rollback strategy
  • Final production outcome and lessons learned
