The team:

The Comms team builds and manages the technology that enables Kraken to communicate with customers across multiple channels, including phone, email, live chat and physical post. The team is responsible for both the underlying systems and the product features that support these customer interactions.

A key area of the team is voice and telephony, where they build the technology used by energy and support specialists to speak with customers. This includes managing real-time calls, handling customers and specialists joining or leaving calls, responding to connection and network issues, and ensuring calls can be reliably maintained or recovered when problems occur.

Unlike more traditional transactional backend systems, much of the Comms technology is highly real-time and event-driven. The team works with event streams, queues and continuously changing system states to manage interactions as they happen.
The team also integrates with third-party communication providers, such as Twilio, which supports Kraken’s phone networks and email sending.
Overall, Comms sits at the intersection of engineering, product and customer operations, building the technology that enables Kraken’s customer-facing teams to communicate effectively and reliably with customers.

• Help shape the technical direction of the Comms team as it grows, contributing to how the team’s focus, systems and ways of working evolve.
