We are tech transformation specialists, uniting human expertise with AI to create scalable tech solutions. With over 8,000 CI&Ters around the world, we’ve built partnerships with more than 1,000 clients during our 30 years of history. Artificial Intelligence is our reality. As a System Architect, you will be the technical visionary responsible for designing, defining, and governing the high-level structure of our enterprise software ecosystems. You will bridge the gap between business strategy and technical execution, making high-stakes decisions regarding frameworks, platforms, and infrastructural patterns. Your expertise will be vital as you steer engineering teams toward scalable, secure, and resilient cloud-native architectures, managing technical debt while driving modern innovation. Responsibilities: - Architectural Blueprinting: Define and maintain the overarching architectural vision, designing blueprints for scalable, distributed, and highly available systems. - Technical Governance: Establish technical standards, coding guidelines, and architectural guardrails, ensuring compliance across multiple engineering squads. - Technology Evaluation: Lead the evaluation, prototyping, and selection of modern tools, platforms, and frameworks (such as choosing between monolithic vs. microservices, or specific database technologies). - Cross-Functional Alignment: Partner with Product Managers, Security Officers, and Engineering Leads to translate complex business strategies into viable, future-proof technical roadmaps. - Risk & Performance Management: Conduct architectural reviews and root cause analyses on system bottlenecks to optimize for latency, throughput, and cost-efficiency. - Mentorship & Advocacy: Champion engineering excellence by mentoring Tech Leads and Senior Developers, fostering a proactive and autonomous engineering culture. Qualifications: - Professional Experience: 8+ years of experience in software engineering, with at least 3+ years acting in a dedicated System Architect or Principal Engineer capacity. - Architectural Mastery: Deep knowledge of enterprise integration patterns, microservices architecture, Event-Driven Architecture (EDA), and Domain-Driven Design (DDD). - Cloud & Infrastructure: Hands-on expertise architecting cloud-native solutions on AWS, Azure, or GCP, including serverless computing, container orchestration (Docker, Kubernetes), and Infrastructure as Code (IaC). - Data Architecture: Strong understanding of relational databases (SQL Server, PostgreSQL) and NoSQL solutions (MongoDB, Redis, Cassandra), knowing when to apply each model. - Security & Compliance: Proven track record of designing secure systems, factoring in identity management (OAuth/OIDC), data encryption, and network security layers. - Language: Advanced English proficiency (fluent verbal and written communication). Nice-to-have Skills: - DevOps Mastery: Advanced experience with CI/CD automation, service meshes (e.g., Istio), and system observability tools (Datadog, Prometheus, ELK stack). - Legacy Decoupling: Proven experience applying patterns (like the Strangler Fig pattern) to systematically migrate legacy monoliths to modern architectures. - AI/Data Streaming: Familiarity with heavy data streaming tools (Kafka, RabbitMQ) or high-scale AI infrastructure pipelines. - Certifications: Professional certifications such as AWS Certified Solutions Architect Professional, Azure Solutions Architect Expert, or TOGAF. #LI-AM2 \n \nOur benefits: -Health and dental insurance -Meal and food allowance -Childcare assistance -Extended paternity leave -Partnership with gyms and health and wellness professionals via Wellhub (Gympass) TotalPass; -Profit Sharing and Results Participation (PLR); -Life insurance -Continuous learning platform (CI&T University); -Discount club -Free online platform dedicated to physical, mental, and overall well-being -Pregnancy and responsible parenting course -Partnerships with online learning platforms -Language learning platform And many more!
