Description of the offer

About Us

Voiceflow is the leading collaborative conversational AI platform.

Our collaboration platform makes it easy for conversational AI product teams to quickly design, test, ship and iterate on conversational assistants – together, faster, at scale.

Assistants designed and built with Voiceflow span hundreds of use cases, from drive thrus to in-car assistants, call centres and more. Voiceflow is loved by over 80,000 global teams with some of the world’s largest companies as customers including Google, BMW, US Bank, McDonalds, JP Morgan, Spotify, Amazon, Home Depot, Best Buy, John Hopkins, and thousands of others.

We’re biassed of course, but we think we’re building one of the coolest products in the world. Put this claim to the test and try out Voiceflow’s free version yourself – give it a try!

Joining a new company is one of the biggest decisions we all make in life as we’re investing our most important resource – our time. At Voiceflow, we’re investing our time here because we believe in an inevitable future where many of the conversations we have with brands everyday will be increasingly automated. If that’s the future we’re all going to be a part of, then the world needs Voiceflow to ensure the teams building these conversational experiences have great tools to craft great experiences. Think of us like the Adobe creative suite for the growing world of conversational AI. You can learn more about our vision of the future here.

We’ve raised $25M USD the past 2 years from some of the world’s best investors including Felicis, Craft, True, Amazon, Google & CEOs of Figma, Webflow, Eventbrite, InVision, Product Hunt, and more. We’re a small, fast growing remote team of around 35 team members from around the world, composed of dedicated and talented individuals with a core focus on engineering and product.

About the Role

How do we scale a conversational AI platform as assistants become more capable?

That’s the question we’d like your help to answer at Voiceflow. We currently have 100,000+ teams using the platform along with numerous enterprises and are focused on improving their experiences in building voice and chat apps.

You’ll work with our ML Lead and the newly created Data services team to build the first version of the platform and iterate on it as we add more use cases.
