About Knowde

Chemical companies are the hidden innovators behind the end-products we rely on every day. Chemistry is used to make every physical good on earth, including the products we love from Tesla, Glossier, Apple, Nike, 3M, and J&J. And yet, the largest and most impactful industry in the world is still doing business the same way it did 100 years ago.

Knowde is building the first digital marketplace for the $5 trillion chemical industry. Chemical companies use Knowde to market and sell their products online for the first time ever. For buyers, Knowde has become their go-to destination to shop across the entire world of chemistry, all in a single destination.

Buyers use Knowde as their go-to destination to discover and purchase chemicals from any chemical producer, all in one place. By helping pull this industry online, we will accelerate the innovation behind every physical product in the world.

To realize our vision, we've raised over $90M from the world's leading investors, including Sequoia Capital and Coatue.

We have an exciting opportunity for an experienced Search Engineer to join our team. You will be a great communicator with an excellent English level.

We’re building out a two-sided marketplace for the chemical industry which is responsible for 1/4th of global GDP. To support our mission, we’ve embarked on a project to allow our customers to easily find chemical compounds, formulations and documents they may be interested in. This is specifically tailored to the industry we operate in and our customers love it.

This project comes with serious engineering challenges - efficiently ingesting data from a number of different data sources and keeping overall search performance and accuracy in check. We have a dedicated team whose sole purpose is to maintain a complex chemical taxonomy used everywhere in the project. We’re investing in automating as much of this process as is possible - to be able to process a magnitude more data than we do currently.
