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.

• 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.
