About Builder.ai

Innovation is fueled by the power of possibilities. A few years ago, it was virtually impossible to innovate because building software needed a degree. It was simply too expensive, too complex, too risky, and ultimately, too inefficient. That’s why only 16% of projects were ever completed on budget and worse yet, 78% failed.

We're changing that. We’re flipping software development on its head and kicking out the notion that you need to be an expert or participate in boot camps to learn how to make an app. ’s platform lets you order the perfect software app for whatever problem you’re trying to solve. Our AI-powered assembly line brings together Lego-like reusable features and experts from around the world to bring world-class ideas to life – ANYONE’s world-class ideas. Building software needs to be like ordering pizza – pick what you want, get recommendations for the features you need and all you have to do is wait until it's cooked and ready for you.

Our human-assisted AI platform helps anyone build, run & scale tailor-made software. Everyone from the bakery in Riyadh and nursery in London, to large fortune 100 companies like the BBC or Pepsi.

Life at Builder.ai

It’s a place where everything moves at lightning speed and it’s certainly not for the faint of heart. We celebrate diversity and push everyone to do more with less, while creating and championing a culture that empowers everyone to experiment, push boundaries and learn by doing. Every Builder runs to our core value system of HEARTT (Heart, Entrepreneurship, Accountability, Respect, Trust & Transparency) and we’re always looking for team players with a point of view, a sense of humility and a let’s-get-stuff-done attitude.

Why we need this role

Our Engineering team is growing quickly and we are hiring in every single team from our customer products (CX) & delivery tools (DX) all the way to our Assembly Line (BX) & Cloud systems teams.
