This is backend product engineering, not integrations-only, not AI-first, and not DevOps or data engineering. The environment is Python-heavy on AWS with high-volume document and event processing, SFTP ingestion, OCR, orchestration, queues, and retries. AI is a component of the product, not the center of your career. The CTO runs a live coding round, so this is for someone still writing code every day. Top of the Senior band or early Staff, roughly four to nine years, backend-focused.
