Diabolocom enables organizations worldwide to build brand loyalty and drive sales growth. Our innovative, cloud-based contact center solution leverages AI-driven technologies to optimize the customer experience. We empower Customer Service and Sales teams to handle inbound and outbound interactions seamlessly across multiple channels, ensuring premium voice quality, real-time analytics, and robust global scalability.

Our platform integrates with leading CRMs and offers a wide range of APIs and services in multiple languages. With offices in Europe, the USA, Brazil, and the UAE, and 350+ clients operating in 60+ countries, we are constantly evolving and seeking talented individuals to join our team.

About the Message Squad

Message Squad is dedicated to building and evolving services that enable our clients to communicate across various text-based channels. Initially focused on email, using Java 21 and Spring Boot, we have expanded to a more generic Go-based solution that integrates text channels through specialized adapters.

Our current infrastructure supports SMS and WhatsApp, leveraging:

• gRPC for synchronous communication

• RabbitMQ for asynchronous messaging

• PostgreSQL as our primary data store

Beyond supporting multiple channels, we implement various protocols, such as IMAP/SMTP for email, SMPP for SMS, and external APIs for WhatsApp. Additionally, we build in-house Golang libraries to simplify the creation and maintenance of Go services across the organization, for example test-container library, streamlining integration testing both locally and in GitLab CI.

What’s next for the Message Squad?

• Expand our text-channel integrations to include Facebook Messenger, Instagram, and RCS.

• Enhance existing features, such as enriched text formatting and forwarding capabilities.

• Collaborate on cross-team features with product owners and other squads.
