Описание

SmartCore is a fintech holding building infrastructure for the next generation of payments. Our solutions cover the entire financial operations cycle — from core banking and processing to cards, wallets, and anti-fraud systems. Our core area is card acquiring, ensuring high-speed and secure payment processing. Over the past five years, we have built a reliable infrastructure across the EU and CIS, launched our own payment solutions, and continue to grow actively.

• Setting up and troubleshooting CI/CD: image building, deployments, and pipelines.
• Monitoring logs and alerts (Grafana, Prometheus, CloudWatch).
• Investigating incidents (on-call) and assisting the development team with deployments and environments.
• Managing Cloudflare: DNS, CDN, WAF, and certificates.
• Maintaining ClickHouse and the rest of the data layer (PostgreSQL, Redis, Kafka, MongoDB).
• Ensuring security compliance: accesses, secrets, network, and PCI / ISO requirements.

Требования

• AWS: 4+ years of production experience (VPC, IAM, EKS, ECS, RDS, load balancing, secrets).
• Kubernetes: Practical experience with EKS, deployments, debugging, Ingress, IRSA.
• Infrastructure & CI/CD: Strong skills in Terraform (modules, state), Terragrunt, Helm + GitOps (ArgoCD), Docker, and CI/CD tools (GitHub Actions / CodeBuild).
• Tech Stack: Experience with ECS Fargate, Kafka / MSK, ClickHouse, Cloudflare (DNS, CDN, WAF), Grafana + Prometheus / AMP, CloudWatch, External Secrets, and Karpenter.

• Languages: Russian and English (sufficient for documentation and AWS).

Условия

Impact: Opportunity to join at the origins of the project with a lot of new design and development. Direct access to technical decision-making and no bureaucracy. Environment: Agile processes based on Scrum without unnecessary bureaucracy. Location: Full-time, flexible schedule, comfortable remote work in a European time zone, or relocation assistance to Barcelona, Spain. Culture: We invest in engineering quality (modern tools, documentation, clear processes) and provide experience working in a large holding with its own infrastructure.
