Responsibilities:

Technical leadership & delivery ownership

• Own end-to-end technical execution for modernization and migration initiatives (scope, design, implementation, quality, and delivery milestones).

Modernization strategy (from .NET MVC to cloud-native)

• Assess current .NET/C#/MVC applications (dependencies, coupling, data access patterns, hosting, performance bottlenecks, security gaps).
• Define modernization approach per capability: rehost/refactor/re-architect/replace, prioritizing quick wins and risk reduction.

AWS cloud-native implementation

• Design and guide build-out of cloud foundations required for modern apps (networking, environments, security, observability, CI/CD).
• Ensure production readiness: performance testing strategy, failure-mode testing, rollout/rollback procedures.

Migration to existing AWS/Java (Spring/Hibernate) platforms

• Lead functional migration from .NET codepaths to Java-based services while maintaining correctness and availability.
• Define interoperability approach during transition (API contracts, adapters, strangler pattern, feature toggles, compatibility layers).
• Partner with platform owners to ensure migrated components comply with existing Java platform conventions and deployment pipelines.

Engineering excellence & SDLC

• Set standards for clean code, code reviews, test automation, branching/release strategy, and environment promotion.
• Drive test strategy across stacks: unit, contract, integration, regression, and end-to-end tests; improve automation coverage.
• Improve build/release reliability; reduce cycle time; implement guardrails (quality gates, vulnerability scanning as applicable).

Security, compliance, and risk management

• Embed secure engineering practices (threat modelling participation, secure coding standards, dependency hygiene).
• Ensure appropriate handling of secrets/credentials, least-privilege access, and auditability.
• Identify technical risks early (data migration risk, downtime, coupling, unknown dependencies) and drive mitigation plans.

Team mentorship & upskilling (explicit people mandate)

• Create an upskilling plan for the existing team: learning paths for AWS fundamentals, Java/Spring, cloud-native patterns, and DevOps practices.

Stakeholder collaboration

• Partner with product/business stakeholders to prioritize modernization deliverables and manage trade-offs (time, scope, risk).

Coordinate with security, infrastructure/platform, and data teams to remove blockers and align on shared standards.
