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 ## Description We are looking for two Cloud Application Modernisation & Agentic Architects (f/m/d) to own the end-to-end refactoring of Thinkproject's 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 fast: 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., 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, * 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 * You need a stable architecture foundation before you start - legacy migration means working with what exists * You are a specialist in one cloud (Azure or GCP) but not both * You treat project management as someone else's job * You have not handled a production rollback under pressure What we offer * Multicultural team across 7 countries (Germany, France, UK, UAE, Spain, New Zealand, Australia) * Hybrid-first working * Continuous learning & certification budget * Open, inclusive, and high-ownership culture * Learning programmes | Career growth | Leadership access ## Related Videos - [The journey from developer to devops - what i've learnt along the way](https://www.wearedevelopers.com/videos/238-the-journey-from-developer-to-devops-what-i-ve-learnt-along-the-way) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Kubernetes and Microservices with Multi-Model Databases](https://www.wearedevelopers.com/videos/382-kubernetes-and-microservices-with-multi-model-databases) - [Database DevOps with Containers](https://www.wearedevelopers.com/videos/145-database-devops-with-containers) - [AWS Migration within 3 months](https://www.wearedevelopers.com/videos/196-aws-migration-within-3-months) ## Related Articles - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [7 Cloud Computing Trends Coming in 2025 for Developers](https://www.wearedevelopers.com/magazine/412-7-cloud-computing-trends-coming-in-2025-for-developers) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Mastering Remote Work: Tips for Developers](https://www.wearedevelopers.com/magazine/558-mastering-remote-work-tips-for-developers)
