  • Work closely with the founder to translate business needs into technical execution
  • Build scrappy but scalable MVP features that deliver real customer value
  • Lead core technical decisions, shape our engineering culture, and help grow the team
  • Translate product vision into scalable code

What We’re Looking For

  • A long-term partner excited to grow with the company
  • Solid experience in full-stack development (front-end + back-end)
  • Proficiency in frameworks like React, Next.js, Node.js, Python, or similar
  • Understanding of and experience with AI and machine learning is a strong plus
  • Passion for building, fast iteration, and launching MVPs
  • A self-starter who thrives in early-stage environments and takes full ownership
  • Collaborative mindset, comfortable working in a lean, focused team
  • Strong product intuition and the ability to balance speed with scalability
  • Bonus: Previous start-up or side-project experience

We’re also open to recent grads or early-career candidates who can show strong potential, drive, and a solid portfolio or projects.

What We Offer

  • Equity-only to start, with the potential for paid compensation after funding
  • A clear path to CTO as we grow
  • Huge creative and technical ownership from day one
  • A builder’s playground, your decisions will shape the product, brand, and company
  • Flexible hybrid work (with in-person catchups when needed)
  • A chance to join early, leave your mark, and build something ambitious

Final Note

We’re not just building tech, we’re building trust and long-term impact. If you’re a builder at heart and this feels like the kind of opportunity you’ve been waiting for, we’d love to talk. Let’s build the future of curated travel together.
