Résumé du poste

Ciklum in Brazil is seeking a Principal Platform Engineer to join our cross-functional team. You will own platform and cloud architecture on AWS, drive modernization efforts, and establish reliable, scalable patterns across deployment environments.

You’ll lead design reviews, mentor senior engineers, and create reusable patterns to simplify complex infrastructure. This role emphasizes security, GitOps, and SRE practices in a fast-paced product environment.

Qualifications

• Platform, infrastructure, DevOps engineering with direct production ownership on AWS.
• IaC: Deep OpenTofu/Terraform proficiency: module authoring, state management, workspace strategy, remote backends, and CI/CD integration
• Kubernetes: Strong Kubernetes operations: EKS and/or AKS cluster lifecycle, Helm, admission controllers, RBAC, network policies, and autoscaling
• Observability & SRE: Hands-on observability experience with two or more of: Prometheus, Grafana, Loki, Tempo, Datadog, or OpenTelemetry — including SLI/SLO definition and alert engineering
• CI/CD: CI/CD platform experience: GitHub Actions pipeline authoring, reusable workflow design, and container build/scan pipeline ownership
• GitOps: GitOps: ArgoCD or Flux for Kubernetes continuous delivery; progressive delivery patterns (canary, blue-green)
• IDP: IDP experience: Backstage or equivalent developer portal, GitHub, scaffolding templates, service catalog design, or self-service provisioning tooling
• Security: Security-first mindset: policy-as-code, IaC scanning, secrets management, container hardening, and shift- left security practices
• Strong communication and documentation skills; comfortable presenting architecture decisions to engineering peers and leadership
• AI/ML infrastructure : LLM API integration or model serving

Responsabilités

• Own platform and cloud architecture
• Define and evolve platform architecture across AWS, including networking, compute, storage, and environment strategy
• Drive cloud modernization initiatives (migration, re-platforming, standardization of deployment patterns, scalability and resilience improvements)
• Create reference architectures and guardrails that enable autonomy while improving consistency and operational quality
• Establish reliability and operational excellence
• Set reliability standards and practices (SLOs/SLIs, error budgets, capacity planning, incident response and postmortems)
• Improve observability and operational readiness (monitoring, alerting, tracing, dashboards, runbooks) to reduce MTTR and recurring incidents
• Identify systemic bottlenecks (latency, throughput, resource utilization, toil) and lead cross-team initiatives to address them
• Establish and evangelize best practices: design docs, architecture reviews, coding standards, testing strategy, CI/CD quality gates, production readiness
• Mentor senior engineers, tech leads, and emerging technical leaders; coach teams through complex designs and tradeoffs
• Create reusable patterns and “golden paths” (templates, libraries, tooling) that make the right way the easy way

About the role:

As a Principal Platform Engineer, you'll become a part of a cross-functional development team engineering experience of tomorrow.

The company builds software for commercial real estate. This isn't general cloud engineering, you will actually built agentic-platform infrastructure before, not just traditional cloud architecture.

Responsibilities:

• Own platform and cloud architecture
• Define and evolve platform architecture across AWS, including networking, compute, storage, and environment strategy
• Drive cloud modernization initiatives (migration, re-platforming, standardization of deployment patterns, scalability and resilience improvements)

• Mentor senior engineers, tech leads, and emerging technical leaders; coach teams through complex designs and tradeoffs
• Create reusable patterns and “golden paths” (templates, libraries, tooling) that make the right way the easy way

• AI/ML infrastructure : LLM API integration or model serving

What’s in it for you?

• Care: your mental and physical health is our priority. We ensure comprehensive company-paid medical insurance and mental health programs, 5 undocumented sick-leave days per year
• Tailored education path: boost your skills and knowledge with our regular internal events (meetups, conferences, workshops), Udemy license, language courses and company-paid certifications
• Growth environment: share your experience and level up your expertise with a community of skilled professionals, locally and globally
• Long-term employment with 20 working-days paid vacation and local bank holidays
• Flexibility: 100% remote work mode
• Opportunities: we value our specialists and always find the best options for them. Our Internal Mobility Program helps change a project if needed to help you grow, excel professionally and fulfill your potential
• Global impact: work on large-scale projects that redefine industries with international and fast-growing clients
• Welcoming environment: feel empowered with a friendly team, open-door policy, informal atmosphere within the company and regular team-building events
