About the Role

We are looking for a Platform Engineer to join our Infrastructure team at Cobre, Latin America's leading instant b2b payments platform. This role involves building and evolving our Internal Developer Platform (IDP) to enable engineers to ship faster, safer, and with less cognitive load.

Key Responsibilities

→Own, maintain, and evolve the Internal Developer Platform (Port.io) as a product and maintain integrations between the IDP and ecosystem tools such as Jenkins/CircleCI, ArgoCD, Terraform, Pulumi, AWS, K8S.
→Design and implement scalable platform capabilities that abstract infrastructure complexity from development teams.
→Build and maintain backend services (Python) that power IDP workflows: scaffolding, self-service actions, validations/guardrails, and orchestration.
→Design APIs and event-driven integrations to connect the IDP with CI/CD, GitOps, IaC, and observability tools.
→Develop reusable libraries and internal services to standardize platform logic across squads (authentication, permissions, templates, audit trails).
→Ensure the platform reduces developer cognitive load and accelerates delivery without compromising security or reliability.
→Provide documentation, internal training, and enablement materials to drive platform adoption, acting as a platform evangelist across squads.
→Implement AI-driven automation and operational intelligence to improve operational efficiency.
→Contribute to incident management and root cause analysis when platform services are involved.
→Lead platform roadmap discussions aligned with business and engineering strategy.

Requirements

✓5+ years of experience in Platform Engineering, SRE, or DevOps roles in cloud-native environments.
✓In-depth technical knowledge of microservices architecture and cloud platforms (e.g., AWS, Kubernetes), along with proficiency in Infrastructure as Code (IaC) tools (e.g., Terraform, Pulumi).
✓Strong experience designing and operating Internal Developer Platforms (Port.io, Backstage or similar) and building production-grade backend services with Python (e.g., FastAPI/Flask), including REST APIs, async workers, background jobs, and integration services.
✓Solid engineering practices: testing (unit/integration), CI pipelines, code quality, versioning, and secure API design (authn/authz, secrets handling).
✓Nice to have experience with event-driven patterns (queues, pub/sub) and designing reliable integrations between systems.
✓Experience integrating multiple engineering tools into cohesive developer workflows.
✓Product mindset: ability to treat the platform as an internal product with roadmap, stakeholders, and measurable outcomes.
✓Strong mindset for automation and continuous improvement with a huge interest in AIOps / AI-driven auto-remediation (n8n, aws bedrock, scripting python…)
✓Understanding of secure-by-design infrastructure principles.
✓Exceptional communication skills to effectively convey complex technical concepts to both technical and non-technical stakeholders.
✓Ability to actively listen and understand diverse team and stakeholder needs, demonstrating empathy in decision-making and conflict resolution.
