Platform Engineer – Payment Infrastructure

Our Payment Hub sits between merchants and multiple payment providers. We want Platform Engineers who go beyond traditional infrastructure work and understand the whole system: application architecture, payment flows, APIs, integrations, infrastructure, networking, observability and production operations. You will design, build, deploy, operate and improve the platform alongside our backend and Rust engineers, with end-to-end ownership.

The lifecycle you will work on: Merchant › API › Decision Engine › Routing › Gateway › Acquirer › Webhook › Reconciliation

What You Will Own

● Platform for payment services: build the runtime, tooling and guardrails Payment Hub services depend on, in Rust / Go or Python.

● Gateway and acquirer operations: support provider connectors, provider health monitoring, automated failover and handling of provider-specific failures, timeouts and response codes.

● Kubernetes and cloud: deploy and operate services with Docker and Helm; manage ingress, networking, autoscaling, secrets, configuration, storage and resource limits on GCP / AWS / Azure.

● Observability: end-to-end visibility with OpenTelemetry, Prometheus, Grafana, Jaeger and ELK / OpenSearch so any transaction can be traced.

● Reliability engineering: high availability, health checks, failure detection, retry and timeout policy, capacity planning and incident response.

● CI/CD and developer platform: pipelines, safe deployment strategies (canary / blue-green), automated rollback and internal tooling that make Payment Hub engineers faster.

● Security: TLS and mTLS, HMAC, encryption, IAM, secrets management, API authentication and secure service-to-service communication.

● Front-End Technology: Have experience building scalable and efficient Front end .( Payment eco-systems preferred).

Networking Depth

• Troubleshoot HTTP/HTTPS, TCP/IP, DNS, TLS, load balancing, NAT, VPC, firewalls, service discovery, ingress/egress and Kubernetes networking.
  
• Istio, Envoy or other service-mesh experience is a strong advantage.
