Site Reliability Engineer Senior

What is Cobre, and what do we do?

Cobre is Latin America’s leading instant b2b payments platform. We solve the region’s most complex money movement challenges by building advanced financial infrastructure that enables companies to move money faster, safer, and more efficiently.

We enable instant business payments—local or international, direct or via API—all from a single platform.

Built for fintechs, PSPs, banks, and finance teams that demand speed, control, and efficiency. From real-time payments to automated treasury, we turn complex financial processes into simple experiences.

Cobre is the first platform in Colombia to enable companies to pay both banked and unbanked beneficiaries within the same payment cycle and through a single interface.

We are building the enterprise payments infrastructure of Latin America!

What we are looking for:

The Cobre Infrastructure team and their SRE engineers are professionals who face the daily challenges that allow us to improve the technological level of our products. We enjoy each project or task, giving 100% and learning from each other. Our main goal is to maintain the reliability of our systems. To achieve this, we collaborate with other teams to find the most effective solutions, maintain high-reliability processes, adopt the necessary safety measures and optimize time and cost in every decision.

We are evolving from traditional SRE practices toward a true Platform Engineering model, where infrastructure is abstracted, automated, and productized. This role is about building and evolving the Internal Developer Platform (IDP) that enables our engineers to ship faster, safer, and with less cognitive load.

If you are passionate about cloud-native systems, automation, DevEx, and platform thinking, this role is for you.

What would you be doing:

• 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.

What do you need:

• 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.
