Senior Backend Engineer - ML

What's the opportunity?

Intercom’s Machine Learning team is responsible for defining new ML features, researching appropriate algorithms and technologies, and rapidly getting first prototypes in our customers’ hands.

We are an extremely product focussed team. We work in partnership with Product and Design functions of teams we support. Our team's dedicated ML backend engineers collaborate with scientists to deeply understand research context, and enable us to move to production fast, often shipping to beta in weeks after a successful offline test.

We are very passionate about applying machine learning technology, and have productized everything from classic supervised models, to cutting-edge unsupervised clustering algorithms, to novel applications of transformer neural networks. We test and measure the real customer impact of each model we deplo

If you excel in scaling backend systems but have a bit less hands-on experience with ML systems (which you happily make up for with your keen interest), we'd love to hear from you! 🌟

What will I be doing?

• Taking algorithms which work offline, and putting them in a production setting
• Deeply understand and modify as needed
• Solve hard scalability and optimization problems
• Improving our dev tooling
• Run production ML infrastructure, and evolving it over time
• Build new data infrastructure to enable exploration
• Establish processes for large scale data analyses, model development, validation and implementation
• Work with teammates to measure and iterate on algorithm performance
• Partner deeply with the rest of team, and others, to build excellent ML products
