• Strong PostgreSQL skills

• Hands-on AWS experience

• Solid understanding of microservices, API design, and distributed systems trade-offs

• Comfort with CI/CD, containerization, and modern DevOps practices

Nice to Have

• Experience in FinTech, blockchain, or crypto

• Familiarity with KYC / KYT / AML workflows or providers

• Docker / Kubernetes (EKS, AKS)

• Infrastructure-as-Code (Terraform, Bicep)

• Event-driven architectures (Kafka, RabbitMQ, Service Bus)

• Observability tooling (OpenTelemetry, Datadog, Grafana)

• A strong interest in developer experience and security

What's on Offer

• Competitive salary and performance bonus

• Retirement and medical benefits

• Additional perks and allowances
