Experience working on payment systems, financial services platforms, or other high-compliance, high-availability domains Experience applying AI/ML to operational problems such as anomaly detection, transaction pattern analysis, log summarization, automated diagnostics, or intelligent alerting Familiarity with security and compliance considerations in financial and payment systems (PCI-DSS, tokenization, encryption at rest and in transit) Experience with Infrastructure-as-Code tools such as Terraform or Pulumi as a tooling builder Experience building systems that require strong correctness guarantees - idempotency, exactly-once processing, auditability, and data integrity at scale. Build intelligent tooling - from automated incident triage and transaction-aware root cause analysis to AI-assisted debugging and runbook generation - that meaningfully reduces on-call burden, accelerates resolution of payment-critical incidents, and improves developer productivity across WPC.7+ years of experience in software engineering with a strong emphasis on building backend systems, platforms, and tooling Proven experience building observability or reliability tooling such as monitoring systems, alerting platforms, log pipelines, tracing infrastructure, or diagnostic tools.
