[Job 30278] SRE (DevOps)

Description

At CI&T, we help major enterprises transform the potential of AI into real business impact through AI Deployment, AI-native execution, and tech-integrated business solutions. With 30 years of experience in technological transformation, we accelerate innovation with expertise in agentic SDLC, application modernization, Data & AI, martech, and business strategy. We are 8,000 CI&Ters across more than 25 countries, collaborating to build solutions with real impact. AI is already part of how we work, evolve, and innovate every day. **Important**: If you reside in the Campinas Metropolitan Region, your physical presence at our city offices is mandatory, per our current attendance policy. SRE (DevOps) About the opportunity We are seeking a Senior SRE/DevOps professional to support and evolve the primary infrastructure environment for high-criticality digital products. This role has two core focuses: designing and operating a resilient AWS multi-region architecture, and building mobile (iOS and Android) delivery pipelines that accelerate and standardize the release cycle. This is a highly autonomous position where you serve as a technical reference, balance reliability with delivery speed, and disseminate a culture of reliability engineering across squads. Responsibilities AWS Multi-Region Architecture & High Availability \- Design and implement a multi-cluster, multi-region strategy (e.g., São Paulo and Canada, per corporate standards), including a verticalized approach — partitioning the application into two or three clusters segregated by domain/responsibility. Define replication, failover, traffic routing, and RTO/RPO targets, ensuring scalability and high availability for sustainable growth. Cross-Region Service Migration & Enablement \- Lead the cross-region movement and enablement of core platform components, including: DynamoDB multiregion (global tables), Amazon Cognito multiregion (in collaboration with Platform and Authentication teams while the current identity solution remains in use), and migration of the API Gateway to the new region. Map and review deprecated Lambda functions (across Platform and vertical teams) to enable cross-region movement. Infrastructure Automation & CI/CD \- Develop tools and automations that reduce operational toil in provisioning, deployment, and operations. Maintain Infrastructure as Code using Terraform and configuration management with Ansible, promoting environment standardization and reproducibility. Evaluate and adopt internal tools/platforms for standardized provisioning where applicable. Mobile Pipelines (iOS / Android) \- Build and maintain CI/CD pipelines for mobile applications, covering build, code signing, automated testing, and distribution (App Store Connect / Google Play). Automate certificate, provisioning profile, and release workflow management, integrating tools such as Fastlane into existing pipelines. Observability & Monitoring \- Configure and maintain end-to-end monitoring, dashboards, and alerts. Define SLIs/SLOs and instrument services with Dynatrace, Prometheus, and Grafana, creating integrations that standardize telemetry across systems. FinOps \- Promote FinOps practices (spend visibility, rightsizing, savings plans, anomaly alerts) and continuous cloud cost optimization, accounting for the impact of multi-region scenarios on consumption. Reliability & Incident Response \- Diagnose and resolve production incidents, minimizing impact and recovery time. Conduct blameless post-mortems and drive continuous improvement from incidents. Security & Collaboration \- Apply production security best practices (secret management, least privilege/IAM, hardening). Work closely with development teams to elevate application reliability and efficiency. Requirements Solid hands-on experience with AWS: Kubernetes (K8s/EKS), API Gateway, S3, containers, AWS Lambda, Load Balancers, and others. Proven experience with multi-region and multi-cluster architectures: verticalized application partitioning, data replication, failover, DR, and global routing. Practical experience with DynamoDB global tables and multi-region replication strategies. Experience with Amazon Cognito and/or other identity solutions in distributed environments. Experience migrating services across regions (API Gateway, Lambda, etc.), including analysis and refactoring of deprecated functions. Experience with mobile (iOS and Android) CI/CD pipelines: build, code signing, testing, and app store distribution. Proficiency in Infrastructure as Code with Terraform and automation with Ansible. Experience with Jenkins (configuration and maintenance of CI/CD pipelines). Hands-on experience with Dynatrace (dashboards, alerts, integrations) and with Prometheus and Grafana. Strong understanding of scalability and high availability. Experience in FinOps and cloud cost optimization. Scripting language knowledge, preferably Python and Bash. Understanding of production security practices. Nice-to-haves Experience with Fastlane and mobile release automation (certificate/provisioning management). AWS certifications (e.g., Solutions Architect, DevOps Engineer). Experience in regulated environments (financial services/insurance) and compliance requirements. Experience with GitHub Actions, GitLab CI, or other CI/CD platforms beyond Jenkins. Formal SRE culture (SLO definition and management, error budgets).
