[Hiring] System Architect @CI&T

Role Description

As a System Architect in our development center in Brazil, you will design the end-to-end systems that power digital products for clients in the US. You will own how applications, infrastructure, networks, and integrations fit together, so that solutions are secure, scalable, observable, and cost-effective. You will work hands-on with development, DevOps, and security teams, and with client stakeholders from discovery through go-live. Advanced or fluent English is required, since you will communicate with international teams and clients throughout the workday.

• System design: Define the end-to-end architecture of solutions, covering applications, data, integrations, infrastructure, and networking, with clear trade-offs on scalability, availability, performance, and cost.
• Discovery and requirements: Take part in technology-focused discovery phases. Translate business and non-functional requirements into technical designs, and support pre-sales with solution proposals and estimates.
• Cloud and infrastructure: Design cloud environments (AWS, GCP, or Azure), including networking, firewalls, routing, VPNs, virtualization, and containers. Drive Infrastructure as Code adoption with tools such as Terraform and Ansible.
• DevOps and DevSecOps: Define CI/CD pipelines, branching strategies with Git, and package, image, and container registries. Embed security practices and automated testing into the delivery flow.
• Observability and reliability: Set standards for monitoring, logging, and alerting. Define SLOs, capacity plans, and disaster recovery strategies.
• Cost management: Estimate infrastructure costs during design and monitor them in production, proposing optimizations as usage grows.
• Integrations: Design APIs and integrations with external systems such as CRMs, ERPs, and partner platforms, ensuring interoperability and secure data exchange.
• Technical leadership: Guide and mentor engineers, review designs and code, and promote knowledge sharing across teams.
• Risk mitigation: Identify technical risks early, propose mitigation plans, and alternative solutions.
• Documentation: Produce and maintain architecture diagrams, decision records, and implementation guidelines, and explain them clearly to technical and non-technical audiences.

Qualifications

• Solid knowledge of architecture patterns for distributed systems, microservices, and cloud-native solutions.
• Hands-on experience with at least one major cloud provider (AWS, GCP, or Azure).

• Experience with virtualization, Docker, and containerized workloads.
• Infrastructure as Code with Terraform, Ansible, or similar.
• DevOps or DevSecOps practices, including Git, CI/CD pipelines, and artifact/container registries.
• Monitoring, logging, and alerting tools (e.g., New Relic, Prometheus, Grafana, ELK).
• Experience estimating and monitoring infrastructure costs.
• Programming experience in at least one language such as Java, Python, JavaScript/Node.js, or PHP.
• Experience with technology discovery phases and translating requirements into architecture.
• Strong communication skills and the ability to work with cross-functional teams and client stakeholders.
• Advanced or fluent English.
