About the role

Own critical services, mentor engineers, and interface with clients. Ship API-first Python systems, automate dispute / chargeback workflows, and run reliable data pipelines on AWS and Kubernetes with Terraform-managed infra.

Responsibilities
  • Lead projects, designs, and reviews; mentor junior / mid engineers.
  • Build and operate REST APIs in Python (versioning, idempotency, auth / OIDC, webhooks).
  • Automate ops: evidence assembly, reconciliations, SLA timers, notifications, approvals.
  • Model data with SQLAlchemy on MySQL / Postgres; use ClickHouse and S3 / Parquet.
  • Run services on AWS with Docker + Kubernetes (Helm / Kustomize, GitOps optional).
  • Define infrastructure with Terraform (modules, state, policy checks).
  • Add observability (logs / metrics / traces), CI / CD with GitHub Actions, safe rollouts.
  • Collaborate with teams on API contracts, performance, and security.
  • Integrate device intelligence and bot‑mitigation with privacy controls.
Required
  • Proven REST API design and operations at scale.
  • Payments / fintech: disputes / chargebacks, reconciliation, integrations.
  • Orchestration / workflows and event‑driven patterns; human‑in‑the‑loop.
  • AWS, Docker, Kubernetes in production; GitHub Actions; observability.
  • Terraform in production (modules, remote state, policy as code).
  • Systems basics: networking / concurrency, performance.
Nice to have
  • Kafka / Kinesis / SQS, Airflow / Prefect / Dagster, PCI / SOC 2, and FastAPI / Flask.
How to apply

Send an English resume and links to APIs / code / docs showing Python, Terraform / Kubernetes, Angular, automation, and payments / chargebacks work.
