Principal Site Reliability Engineer (SRE)

About the role

We are looking for a Principal Site Reliability Engineer to design, build, and operate a greenfield, cloud‑native platform on AWS. This senior individual‑contributor role focuses on proactive platform engineering, developer enablement, and reliability architecture rather than routine ticket handling.

Key responsibilities

• Build self‑service developer tooling, golden paths, and automated environment‑provisioning pipelines for safe, independent microservice deployment.
• Provision, harden, and manage production‑grade Amazon EKS clusters using modular Terraform, Karpenter autoscaling, and GitOps delivery patterns.
• Design and implement the organization’s incident response model, on‑call escalation policies, and blameless post‑mortem processes from scratch.
• Lead enterprise‑wide Datadog implementation, including APM, distributed tracing, custom metrics, SLO definition, and actionable alerting.
• Architect GitHub Actions CI/CD workflows supporting zero‑downtime progressive delivery (Canary, Blue/Green) with automated health verification.
• Partner with Solution Architects to establish robust cloud network segregation (VPCs, transit gateways, IRSA, ingress security boundaries).

Required profile

• 7+ years of experience as an SRE, Platform Engineer, or similar role focused on cloud‑native infrastructure.
• Proven ability to design incident response frameworks, on‑call models, and blameless post‑mortems.
• Strong English proficiency (B2 level or higher).

Required skills

• AWS, Amazon EKS, Kubernetes
• Terraform, Karpenter, GitOps
• Datadog (APM, distributed tracing, custom metrics, SLOs, alerting)
• GitHub Actions, CI/CD, Canary & Blue/Green releases
• Cloud network architecture: VPC, transit gateways, IRSA, ingress security
• Kotlin backend ecosystem
• React Native mobile ecosystem

What we offer

• Innovative projects with global impact for industry leaders.
• Flexible work environment – vibrant office or remote comfort.
• Opportunities to work abroad up to two months per year.
• Relocation options across 55+ countries.
• Corporate and social events.
• Leadership development, career advising, soft‑skills and well‑being programs.
