We’re hiring Senior/Staff Software Engineers, but we care more about ownership and judgment than title. You'll work on designing and evolving foundational data models used across the platform, building backend services, workflows, and automation systems end-to-end, applying AI/LLMs pragmatically (automation, reasoning over messy inputs, decision support), and shipping user-facing product features tied directly to real customer workflows. Stack: Python, TypeScript, React, AWS.Remote
