Our portfolio includes Havenly, Interior Define, Burrow, The Citizenry, The Inside, and St. Frank—spanning AI-powered interior design services, custom furniture, and globally-sourced artisan home goods.

With nearly a million designs created and a team of expert interior designers powered by cutting-edge technology, including AI visualization and 3D rendering tools, we're transforming how people discover, design, and furnish their homes. Headquartered in Denver with offices in New York, we're building the future of home at the intersection of technology, design, and consumer experience.

What you'll own

• A meaningful area end to end: a slice of the customer design experience, designer tooling, the iOS app, or a backend service.
• AI-backed features: you'll define how they behave, evaluate output quality, and iterate based on real customer impact.
• Work across the 3D and Studio stack, the TypeScript graph, the PHP monolith, and the agent platform as the work requires.

What success looks like

• In 90 days: you've ramped on the stack and shipped real improvements in your area.
• In a year: you own an area of the platform, you've raised its quality and reliability, and you're the person the team goes to for it.

How we work with AI

AI is a core part of how we build, and we're investing heavily in it, well beyond using it to write code faster.

• The team works with Claude Code, Codex, and Cursor and builds on our agent platform and LLM tooling.
• We're building an internal harness so agents can handle real engineering work, like error resolution, bug fixes, and feature enhancements, around the clock.
• You'll use AI intentionally, help push this forward, review output critically, and stay accountable for everything you ship.

Must-haves

• Strong full-stack fundamentals. You understand how web, mobile, APIs, services, and databases fit together.
• You use AI tools as a real part of your engineering workflow and own the output.
• You've owned meaningful parts of a product or system in production.
• You ramp quickly and are comfortable with ambiguity and unfamiliar code.
