What you'll do 💻
As a Senior Backend Engineer, you’ll be fully engaged in product development: bringing relevant features to customers, improving production code, and collaborating across functions to create next-generation CX products.
More specifically, you’ll work in the Conversational Intelligence (CI) team. Our CI product analyses customer interactions and provides automated, easy-to-use insights that help address knowledge gaps and inefficiencies and unlock opportunities across the entire organisation. To do that, our product relies on seamlessly pulling new and updated data from other systems, and a key part of this role is right there: taking ownership of some of our integrations and APIs, not only maintaining them but also modernising and improving how they are built.
You won’t be tackling challenges alone. We put a strong emphasis on collaboration and on creating an environment that supports your personal and professional growth. We expect you to be proactive, curious and a team player, and to contribute to our workplace atmosphere in your own unique way.
Key Responsibilities
- Design, build and maintain scalable backend services powering our AI products
