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.

 

Responsibilities:

- 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.
