Cloud Application Modernisation Architect (f/m/d)

Location: Pune (IND)

Discipline: Software Development

Job Type: Fulltime

Job Summary

We are looking for two Cloud Application Modernisation Agentic Architects (f/m/d) to own the end-to-end refactoring of Thinkprojects application portfolio 10 applications, 3 of which are major, mission-critical products. You will work as a pair, splitting application ownership between you, and you are expected to move rapid: full refactoring across the portfolio within 6-8 months.

This is not a design-and-delegate role. You will roll up your sleeves, conduct the refactoring hands-on, and manage the project simultaneously. You are both the engineer and the project manager. You will consume the Service Catalog built by the Cloud Infrastructure Agentic Architect and the networking foundation laid by the GCP Network Agentic Architect and turn them into modernised, cloud-native applications that are more reliable, more scalable, fully observable, and cheaper to run.

Time allocation (approximate):

~50% hands-on application refactoring migration | ~25% project management, planning stakeholder coordination | ~15% collaboration with DevOps, SecOps, Compliance SRE | ~10% observability, testing validation

Key Responsibilities

Application Refactoring Modernisation

- Own the end-to-end refactoring of your assigned applications from assessment and design through implementation and validation
- Apply 12-factor app principles, event-driven architecture patterns, and cloud-native design to legacy codebases
- Migrate workloads from on-prem and legacy infrastructure to GCP-native services: Cloud Run, GKE, serverless functions, managed databases, Pub/Sub
- Design for scalability and on-demand resource consumption cost efficiency is a success metric, not an afterthought
- Use LLM-assisted tooling (Claude Code, OpenCode, or equivalent) to accelerate refactoring, code modernisation, and IaC generation

Project Management Delivery

- Own the migration plan for your applications: timeline, milestones, dependencies, risks, and rollback strategy
- Track and report progress with precision - this is a time-boxed programme (6-8 months); delays must be surfaced early
- Split application ownership with your paired architect: clear DRI per application, shared standards

Resilience Rollback





- Define and test rollback plans for every application before migration begins - you have crisis experience and you use it
- Handle incidents during migration with calm, methodical rollback and root cause analysis
- Ensure every migrated application meets reliability and observability standards before handover

Collaboration

- Work closely with DevOps to integrate migrated applications into CI/CD pipelines and automated deployment workflows
- Collaborate with SecOps and Compliance to ensure every migrated application meets security controls and certification requirements
- Engage SRE teams to validate observability, SLO definitions, and alerting coverage post-migration
- Consume and provide feedback on the Service Catalog you are one of its primary consumers

What you need to fulfill the role

Required Skills Qualifications

- You have migrated complex, production applications from on-prem to cloud at scale, under time pressure, and lived to tell the story. Specifically:
- Proven on-prem to cloud migration experience at scale, under tight time constraints; you have delivered migrations, not just designed them
- Strong proficiency across both Azure and Google Cloud Platform networking, infrastructure, and PaaS layers
- Deep hands-on experience with Docker, VMs, GKE and AKS node management, and serverless design patterns (Cloud Run, Cloud Functions, Azure Functions)
- Strong 12-factor app knowledge you apply it in code, not just reference it in presentations
- Strong event-driven architecture experience Pub/Sub, event streaming, async decoupling patterns
- Crisis and rollback experience you have handled production incidents during migrations, executed rollbacks cleanly, and conducted honest post-mortems
- Proven focus on scalability and on-demand resource design your migrations reduce cost, not just shift it
- Proven hands-on agentic experience: must have used Claude Code, OpenCode,



or equivalent LLM-based coding agents in real engineering workflows
- Comfortable operating in ambiguity 10 applications, varying legacy states, evolving requirements; you create clarity

Nice-to-Have (Bonus Skills)

- Strong cloud networking experience (VPCs, firewall rules, private connectivity)
- FinOps awareness cost attribution and rightsizing post-migration
- Experience with SecNumCloud or C5 compliance in a migration context
- Prior experience as both engineer and delivery lead on the same programme

Soft Skills

- Extreme ownership you own the outcome for your applications, not just the tasks
- Strong project management discipline: you track details, surface blockers early, and never let a deadline slip silently
- Collaborative by default you pair well with your counterpart architect and with DevOps, SecOps, SRE, and Compliance
- Crisis-calm: you have been in production incidents during migrations and know how to lead through them
- Intense technical curiosity you follow the market, test new tools, and bring relevant innovations into the refactoring programme
- Fact-driven communicator: you report progress with data, not narrative

What success looks like

- Month 2: Application portfolio assessed; ownership split agreed with paired architect; migration plan per application documented with milestones, dependencies, and rollback strategy
- Month 4: First 4 applications refactored and in production (2 major + 2 add-on) observable, scalable, cost-attributed
- Month 6: 7-8 applications fully migrated; third major application on confirmed migration path or complete; observability standard adopted across migrated apps
- Month 8: All 10 applications refactored and live on GCP; full observability in place; reliability and scalability improvements measured and reported; FinOps baseline established per application

Success is defined as: more reliability, more scalability, full observability, lower cost across all 10 applications.

You're probably not a fit if

- You have designed cloud migrations but have not personally executed them in production
