Full Stack AI Engineer
Fifth Wall Ventures
Software Engineering, Data Science
California, USA
We're an early-stage startup led by an experienced founder with multiple exits, building a new software platform for a large and underserved industry that has seen surprisingly little innovation despite representing hundreds of billions of dollars in annual economic activity.
We're looking for an exceptional engineer to join us as one of the first technical hires and help shape the product, architecture, and company from the ground up.
This is a true founding role. You'll work directly with the founder, make foundational technical decisions, and have meaningful influence over both product direction and long-term company strategy.
- Build and ship product from zero to one
- Design scalable systems and architecture
- Work across frontend, backend, mobile, and AI-enabled workflows
- Rapidly prototype, test, and iterate
- Collaborate directly with customers to understand real-world problems
- Help establish engineering culture and technical standards
- Contribute to hiring and team building as we grow
- Strong product instincts
- Full-stack engineering experience
- Comfort operating in ambiguity
- Ability to move quickly without sacrificing quality
- Passion for, and experience in, AI and emerging technologies
- Curiosity, ownership, and a bias toward action
Experience with any of the following is a plus:
- Mobile development
- Modern AI platforms and APIs
- Workflow automation
- Fintech or payments
- Marketplace products
- Enterprise software
- Significant ownership and equity
- Opportunity to help define an entire category
- Direct access to customers and decision-making
- Small team, high trust, low bureaucracy
- Chance to build a company from the earliest days
We're less interested in résumés than in builders.
If you've ever wanted to help create something meaningful from scratch—and have the technical range and ambition to match—we'd love to hear from you.
