Role Overview
The Payment Hub sits between merchants and multiple payment providers. As a Platform Engineer, you will go beyond traditional infrastructure work and understand the entire system: application architecture, payment flows, APIs, integrations, infrastructure, networking, observability, and production operations. You will design, build, deploy, operate, and improve the platform alongside backend and Rust engineers, taking end-to-end ownership. The lifecycle you will work on: Merchant → API → Decision Engine → Routing → Gateway → Acquirer → Webhook → Reconciliation.
Key Responsibilities
- Platform for payment services: Build the runtime, tooling, and guardrails for Payment Hub services in Rust, Go, or Python.
- Gateway and acquirer operations: Support provider connectors, monitor provider health, implement automated failover, and handle 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: Provide end-to-end visibility with OpenTelemetry, Prometheus, Grafana, Jaeger, and ELK/OpenSearch to trace any transaction.
- Reliability engineering: Ensure high availability, health checks, failure detection, retry/timeout policies, capacity planning, and incident response.
- CI/CD and developer platform: Build pipelines, implement safe deployment strategies (canary/blue-green), automated rollback, and internal tooling to accelerate development.
- Security: Implement TLS/mTLS, HMAC, encryption, IAM, secrets management, API authentication, and secure service-to-service communication.
- Front-End Technology: Experience building scalable and efficient frontends (preferably for payment ecosystems).
- Networking depth: Troubleshoot HTTP/HTTPS, TCP/IP, DNS, TLS, load balancing, NAT, VPC, firewalls, service discovery, ingress/egress, and Kubernetes networking. Istio/Envoy or service-mesh experience is a strong advantage.
