About Us: BizTrip.ai is reimagining corporate travel through the power of artificial intelligence. We are redesigning the corporate travel experience from the ground up, and we're looking for passionate innovators who want to transform an industry ripe for disruption. Our founders have deep roots in the travel industry, plus experience at some of the best Silicon Valley companies including Stripe and Heroku. BizTrip was co-founded by Andrew Ng and is backed by his AI Fund. The Opportunity: We're seeking a Founding Engineer who will help architect and build our AI-powered travel platform from the ground up. This is a unique opportunity to shape core technical decisions and establish the foundation of a product that will redefine corporate travel.

As one of our first engineering hires, you'll have extraordinary ownership and influence across our entire stack. You'll tackle complex technical challenges while helping to establish the engineering culture and practices that will scale with our growth.

The Ideal Candidate: The ideal person for this role is someone who cares about craft, but also knows how to balance that with the speed and results required to succeed at a startup.

You should be able talk in depth about how AI tools will enhance your development capabilities and speed, while understanding the limitations and downsides. Beyond speed, you should be passionate about creating exceptional user experiences and unafraid to work across the stack to get something working. You should have a strong belief that great design and UX separates the great products from the average ones. We are a group of creators and builders, and one of our goals is to build a great company. We are doing that, in person, in San Francisco, and we are looking for people that want to work together, in the office. That said, we will resist any “N days in office” rules. Everyone deserves flexibility and we fully expect folks will spend time working outside the office. We will consider full-time remote for truly exceptional candidates. As one of our early hires, you will play a critical role in shaping the culture of our company. With that in mind, we don’t suffer brilliant jerks, slow-witted jerks, nor an unsustainable hustle p0rn culture. We plan to win our market, and we expect to work hard, as a team, to do it.

What You Will Do:

• Design, develop, and deploy key features of our AI travel agent across the full technology stack, but especially the front-end.

• Make crucial technical decisions that balance speed, quality, and scalability.
• Help establish our engineering culture and contribute to technical strategy.
• Work at the speed required to win in the fast moving landscape of AI technology.

What We're Looking For:

• 2+ years of professional software engineering experience.
• Software engineering degree.

• Experience building and shipping production-quality software products.
• Strong communication abilities and collaborative mindset.
• Comfort with ambiguity and ability to thrive in a fast-paced startup environment.
