Job description

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.

Nice to have
  • Native iOS (Swift) experience.
  • 3D, graphics, or visualization experience.
  • Experience building AI or ML-backed product features.
  • Ecommerce or marketplace experience.

Technologies we use
  • AI: Claude Code, Codex, Cursor, an internal agent platform, and LLM tooling.
  • Web and mobile: React/TypeScript and a native iOS app in Swift.
  • Backend: PHP, Node/TypeScript, GraphQL, Python.
  • 3D and Studio: Python rendering, our in-house 3D toolchain (Lunes), floorplan and visualization tools.
  • Infrastructure: AWS, Terraform, Docker.

Interview process
An initial phone screen, followed by two to three rounds of interviews with the team to confirm technical skill, personal fit, and role alignment.
Additional details
  • Location: open to remote candidates in select US locations, with a preference for Denver.
  • Compensation: $150,000 to $185,000, depending on experience. This role is also eligible for company equity.
  • Benefits: generous PTO, volunteer days off, medical, dental, vision, and disability coverage, a 401(k) with company match, free design services, furniture discounts, and merchandise credits.
  • We are accepting applications on an ongoing basis until the role is filled.
  • Havenly is an Equal Opportunity Employer. Applicants must be currently authorized to work in the United States on a full-time basis.
