We are experts in technological transformation, combining human expertise with AI to create scalable tech solutions. With more than 8\.000 CI\&Ters around the world, we have formed partnerships with more than 1\.000 clients during our 30 years of history. Artificial Intelligence is our reality. Important: if you reside in the Campinas Metropolitan Region, your presence in the city offices will be mandatory, in accordance with the current attendance policy Mission: We are looking for a Principal Architect / Architecture Manager to lead the modernization and replatforming of a legacy product, which has an obsolete architecture and strong constraints in modularity and scalability, impacting the client's business objectives. Your mission is to transform this product into a modern, flexible, and modular platform, oriented towards services and APIs, capable of being consumed as a service by other products, enabling its use as whitelabel and multi\-tenant, and supporting growth in scale, high availability, and continuous evolution. Main Responsibilities: * Target Architecture \& Platform: Define the target architecture of the new platform on AWS, including strategies for evolving the monolith into a modular and scalable solution (microservices/domain services, event\-driven, APIs, etc.). Delineate domains and bounded contexts, layers, components, as well as multi\-tenancy and whitelabel models; * Legacy Modernization Journey: Plan and lead the product modernization roadmap, defining decomposition strategies (strangler pattern, extraction patterns, progressive modularization) and coexistence/migration between the legacy and the new platform; * Architecture Governance: Establish architecture principles, patterns, guidelines, and guardrails. Conduct architecture reviews, approve critical solutions, ensure architectural documentation (ADRs, diagrams, catalogs), and guarantee continuous alignment with the architectural vision; * Cloud Based Architecture: Ensure that solutions maximize the use of AWS services, guaranteeing high availability, resilience, performance, security, and cost\-efficiency (including FinOps practices); * Engineering \& Operation Excellence: Ensure the application of engineering best practices (12\-factor, testing, CI/CD, automation, observability, SRE) and resilience (circuit breaker, timeout, retry, etc.), guaranteeing high technical quality, reliability, and operability of the platform; * Technical Leadership \& Architect Development: Provide technical direction, mentorship, and feedback to architects and tech leads. Structure architectural capacity (roles, responsibilities, processes) and raise the technical bar of the ecosystem; * Partnership with Product, Business, and Stakeholders: Work in close collaboration with product, business, and technology leadership to translate strategic objectives into architectural decisions. Participate in discoveries, definition of non-functional requirements (SLOs, security, compliance), and clear communication of solutions to technical and non-technical audiences; * Technical Risk Management \& Evolvability: Identify architectural risks, propose mitigation strategies (technical, roadmap, experimentation), and ensure that the platform is evolvable, supporting new use cases, integrations, business models, and growth in scale. Requirements: * Solid experience in software engineering, acting as a Solution / Systems Architect in complex contexts (multiple teams, multiple systems). * Proven experience in modernizing legacies to distributed and modular architectures, including defining target architecture and migration roadmap, use of decomposition patterns (e.g., strangler pattern, split by domain/subdomain, anti\-corruption layer); * Practical mastery of cloud-based architecture using AWS solutions, ensuring the applicability of high availability, resilience, scalability, and FinOps practices; * Experience in designing service and API-oriented platforms, preferably with domain-oriented architectures (DDD) and exposure of capabilities to other products, partners, and whitelabels; * Experience in architecture governance, definition of patterns, principles, guidelines, and review processes; * Participation in architecture forums and technical decision-making at the organizational level; * Best practices in design, code quality, testing, CI/CD, observability, and SRE; * Knowledge of resilience techniques and tools (circuit breaker, timeout, retry, bulkhead, etc.); * Experience in large-scale development environments: multiple teams, product squads, agile structures; * Integration between product, engineering, operations, and security areas; You will stand out if: * Experience in B2B/B2B2C, whitelabel, or multi\-tenant platforms, with challenges of isolation, configuration, and customization per client; * Experience with FinOps or continuous cost optimization in AWS; * Experience with event-oriented architecture (event\-driven, streaming, CDC, etc.); * Experience with governance pipelines (e.g., architecture boards, techradar, recurring design reviews); * Experience in technical leadership of architects and tech leads, including mentorship, career development, and influence without formal authority. * Ability to communicate complex solutions clearly to technical and non-technical audiences; * Build trust relationships with stakeholders from different areas; * Influence strategic decisions based on data, risks, and architectural trade\-offs. \#LI\-JN1 **Our benefits:** * Health and dental plan; * Food and meal vouchers; * Childcare assistance; * Extended parental leave; * Partnership with gyms and health and well\-being professionals via Wellhub (Gympass) TotalPass; * Profit and Results Sharing (PLR); * Life Insurance; * Continuous learning platform (CI\&T University); * Discount club; * Free online platform dedicated to promoting physical, mental health, and well\-being; * Pregnant employee and responsible parenting course; * Partnership with online course platforms; * Platform for language learning; * And many others More details about our benefits here: https://ciandt.com/br/pt\-br/carreiras At CI\&T, inclusion begins with the first contact. If you are a person with a disability, it is important to **present your medical report during the selection process.** *Check what data needs to be included in the report* *by clicking here.* This way, we can ensure the support and adaptations you deserve. **If you do not yet have the characterizing report, do not worry: we can support you in obtaining it.** We have a dedicated Health and Well\-being team, inclusion experts, and affinity groups that will be with you at every stage.
