Staff Backend Software Engineer

What they're looking for

A Staff Backend Software Engineer to own and architect the entire backend of an AI-native platform that is changing how physical spaces are designed and transformed. You will be the go-to backend engineer at a small startup already live with design-studio and enterprise partners. They want a hands-on builder with startup DNA who has built 0-to-1 products and also knows what good looks like at scale. You might be a rising senior engineer whose scope keeps growing, or a seasoned staff or principal engineer who has done it many times. Either way, you will take on three or four genuinely hard backend problems in real-time collaboration, multi-tenancy and agentic AI systems.

What you'll do

• Own the full backend architecture end to end and make the key design decisions yourself, from a clean slate instead of inside someone else’s framework.
• Design APIs, database schemas and object models that represent complex 3D spatial and design data correctly.
• Build and scale distributed systems with complex async processes, including workflows, queues and data processing pipelines (Kafka, Temporal, Postgres).
• Solve hard architecture problems such as real-time collaborative editing with document revisions, multi-tenant architecture, and connecting agentic AI and computer vision systems to the rest of the platform.
• Work with the CEO, frontend engineers and computer vision engineers to set technical direction and raise the engineering bar as the team grows.
