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
● 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).
- 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.
RequirementsWhat You Bring (Must-Have)
● 3–8 years of software and
platform engineering with strong fundamentals.
● Strong hands-on Kubernetes and cloud infrastructure experience running production workloads.
● Payment gateways, acquirers,
orchestration
● Transaction state and payment
failure handling
● Authorization / capture,
refunds / reversals
● Webhooks and reconciliation
● PCI-DSS concepts and payment
security
● Fintech or banking production
exposure
● Strong Linux and networking
fundamentals; Docker and CI/CD experience.
● Experience with distributed
systems and microservices, including retries, idempotency, ordering and failure
recovery.
● Programming experience in Go,
Rust, Python, Java or similar, and the ability to read application code and
work with backend engineers.
● Strong debugging ability across
application, database, network and infrastructure layers.
● Rust and Go (Must have any one
)
● Helm, Terraform, GitOps
● PostgreSQL, Redis
● Kafka / RabbitMQ / NATS
● Istio, Envoy, OPA
● OpenTelemetry, Jaeger,
Prometheus, Grafana
● Knowlegde with GCP is a Strong
Plus
