Role Overview

We are seeking an experienced Senior Application Architect (Migration Assessment & Modernization Strategy) within the Transformation Solutions & Technology Office, you will be the lead for application portfolio assessment, migration strategy, and modernization roadmap development across complex enterprise client environments.

Where the broader Application Architect role spans design and delivery, this role is specifically anchored in the front-end of the engagement lifecycle — helping clients understand what they have, what it will take to modernize it, and how to sequence and fund the journey. You will work at the intersection of technical depth and strategic advisory, translating sprawling, heterogeneous application estates into structured, executable, cloud transformation roadmaps.

You will be a key contributor to the Solution Engineering, Proposal development, Sales, and Platform Advisory teams — owning the assessment and roadmap narrative that creates the foundation for every winning proposal.

Key Responsibilities

• Lead large-scale application portfolio discovery and assessment engagements across enterprise client environments — covering 100s to 1000s of applications spanning Java, .NET, legacy frameworks, packaged COTS applications, and custom-built systems
• Design and execute application assessment frameworks covering Technical health, cloud readiness, containerization / serverless readiness and potential modernization pathways
• Conduct and Lead application dependency mapping and integration topology analysis
• Lead technical interviews and workshops with client development, operations, and architecture teams to supplement automated discovery data with qualitative context
• Produce formal Application Assessment Reports with executive summary, portfolio heat maps, technical findings, R-Treatment recommendations, and migration / modernization readiness scores per application
• Design target state cloud architectures for complex, multi-tier enterprise applications — spanning web, middleware, and database layers across Java, .NET, and polyglot environments
• Architect DevSecOps transformation pipelines including CI/CD design, automated testing integration, security scanning, and GitOps adoption for modernized application platforms
• Develop and apply structured R-Treatment decision frameworks based on business value, technical health, cloud fit, and strategic priority
• Define application placement strategies with precision — prescribing the right modernization treatment for each application across the 7-Rs
• Design migration sequencing and wave planning strategies — balancing business priority, technical dependency order, risk concentration, and delivery team capacity across multi-year migration programs
• Develop risk registers for migration programs, identifying application-level technical risks, integration risks, data migration dependencies, and organizational change management considerations

Modernization Roadmap Development :

• Translate assessment findings and migration strategy decisions into detailed, milestone driven, multi-horizon modernization roadmaps
• Prepare business case for modernization roadmaps — quantifying expected outcomes while aligning them to Client organizational constraints
• Develop application-level effort estimation models tied to migration wave plans — providing granular, defensible estimates by treatment type, application complexity, and integration scope

Platform & Practice Development :

• Own the assessment and roadmap solutioning narrative for proposals — from discovery scoping through roadmap presentation and commercial structuring
• Lead and support technical solution defense sessions with clients, AWS alliance teams, and partner organizations with confidence
• Collaborate with the Solutions team to build and continuously refine reusable assessment and strategy assets
• Support GenAI-assisted assessment tooling development including automated code analysis, dependency extraction, and cloud readiness scoring acceleration
• Support POC development and platform demo execution, on need basis

Ideal Candidate Profile

• 15+ years of overall IT experience with minimum 5 plus as an Enterprise Architect or Cloud Architect in large-scale environment
• 8–12 years of experience in application architecture with a clear, demonstrated specialization in application portfolio assessment, migration strategy, and modernization roadmap development at enterprise scale
• Proven experience leading application assessment engagements for large enterprise clients with portfolios of 50–1000+ applications across heterogeneous technology landscapes
• Deep expertise in R-Treatment decision frameworks — ability to independently assess, classify, and prescribe modernization treatment for diverse application types with clear, defensible rationale
• Strong understanding of application placement strategy across containerization, serverless, re-platform, and rearchitect patterns — with ability to articulate trade-offs at both technical and business levels
• Hands-on knowledge of application discovery and assessment tooling such as MGN, CAST, Dynatrace, App Dynamics, SonarQube, Veracode and AWS X-Ray
• Strong understanding of cloud-native architecture patterns: microservices, containers (Docker/Kubernetes/OpenShift), serverless (Lambda, API Gateway), event-driven design, and API-first principles — sufficient to assess application fitness for each pattern and design the target architecture
• Experience with DevSecOps toolchains (Jenkins, GitHub Actions, ADO, Terraform, CloudFormation) and ability to define DevSecOps enablement as part of migration roadmaps
• Strong business case development skills — ability to construct TCO models, ROI analyses, and modernization investment justifications for executive audiences
• Excellent written communication and presentation skills — able to produce and present board-quality assessment reports, portfolio heat maps, and roadmap decks
• Proven ability to operate in onsite-offshore engagement models with direct CxO and technical stakeholder engagement
• Prior consulting or pre-sales solutioning experience is strongly preferred

Technical Skills:

• 7+ years of hands-on development experience with .NET Framework / .NET Core and Java (Spring / J2EE).
• 5+ years of experience with enterprise databases, including Oracle, SQL Server, MySQL, and PostgreSQL.
• Strong understanding of application architecture patterns, microservices, APIs, and distributed systems.
• Familiarity with cloud-native architectures, containerization, and modern application frameworks is a plus.
• Strong experience with AWS cloud services and migration best practices.

Education:

• Bachelor's degree in Computer Science, Electrical Engineering, or related field.
• AWS Certified Solutions Architect – Professional preferred.
• Additional certifications such as AWS Certified DevOps Engineer, AWS Certified Security – Specialty, or AWS Certified Advanced Networking – Specialty are a plus.
