Responsibilities

• Lead projects, designs, and reviews; mentor junior / mid engineers.

• Automate ops: evidence assembly, reconciliations, SLA timers, notifications, approvals.
• Design ETL / ELT (batch / streaming), data contracts, schema evolution, backpressure.
• Model data with SQLAlchemy on MySQL / Postgres; use ClickHouse and S3 / Parquet.
• Run services on AWS with Docker + Kubernetes (Helm / Kustomize, GitOps optional).

• 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

• Python expert (3.12+ preferred): typing / mypy, async / multiprocessing, testing, profiling.
• 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).
• Strong SQL; SQLAlchemy; columnar DBs (e.g., MySQL, ClickHouse).
• Systems basics: networking / concurrency, performance.

Nice to have

• Kafka / Kinesis / SQS, Airflow / Prefect / Dagster, PCI / SOC 2, and FastAPI / Flask.
