Senior Software Engineer — ML

Ding’s mission is to enable companies to authenticate their users - at scale - with higher conversion rates and at a lower cost than the market currently offers. Through our platform, customers are able to send OTP codes to their users with the best price to conversion rate ratio available in their current context by selecting the most appropriate channel (SMS via a given carrier vs WhatsApp for example), while preventing costly spam attacks that traditional providers tend to let pass through.Although Ding was founded a year ago, we already have healthy financials and excellent product-market fit. We have a lot of market-shaking ideas and we look forward to implement them with you.We want to build a world-class product and we believe that the way to achieve this is to combine great product design with meticulous engineering. Once we've achieved our goal of providing the best way to send OTP codes to any phone number, we'll be exploring other verticals such as large-scale session management and phone number suggestions, and you could be a key part of these new projects.The teamThe Ding team started with four former Zenly team members, a social network acquired by Snapchat in 2017. We created Ding in response to a problem we had there: the current SMS authentication offering is too expensive, of poor quality and offers little to no protection against spam . We believe that having a small team of committed and skilled people with a flat hierarchical organization is the best way to build a tech company. It forces us to focus on what matters and only on what matters: delivering value to our customers. We also believe that at our current stage, we need to be face-to-face in our offices in the Tour Montparnasse so that ideas can flow freely and collaboration is spontaneous.About the RoleAs a machine learning engineer, you’ll design and build Watch, Ding’s next generation anti-fraud machine learning pipeline.
