Diabolocom builds AI-first, cloud-native contact center infrastructure designed for high availability, low latency, and global scale. As both a software provider and a telecom operator, we combine a fully owned carrier-grade voice backbone with a programmable CCaaS platform that supports real-time, high-volume communications across 60+ countries.

Our architecture integrates proprietary AI models purpose-built for customer interactions and covers data enrichment, intent detection, call summarization, transcription, quality scoring, workflow automation and more. These services run on a modular, service-oriented stack accessible through APIs and engineered for multi-language, multi-region deployments.

We operate a distributed infrastructure optimized for deterministic performance, observability, and resilience, supported by deep CRM integrations, intelligent routing engines, and a high-throughput outbound dialer that enables sub-second decisioning.

A dedicated Diabolocom Research team keeps us at the forefront of technological innovation, designing new proprietary systems—from advanced AI pipelines to telecom optimization—that help our clients gain a competitive advantage in the market.

With more than 20 years of telecom and software engineering experience, Diabolocom offers engineers the opportunity to build and scale enterprise-grade systems that blend AI, cloud infrastructure, and mission-critical communications.

As part of our exponential growth, we are strengthening our internal engineering team and opening a Senior QA Engineer position in our Integration Squad.

About the Integration Squad

The Integration Squad develops and enhances services to integrate with external CRMs like Salesforce, Zendesk and others. Next year we are going to extend Salesforce Voice integration, which opens big market opportunities. Also, we will integrate our AI solutions into our services to provide better experience to our customers.

QA Strategy 

On the QA side, we develop and maintain automated tests using Kotlin and Gherkin. Our test coverage extends across:

- UI tests

- Backend API tests

- RabbitMQ interactions (produce and consume RabbitMQ events to validate integration points)

We strongly believe in a testing pyramid approach: most checks should live close to the code (unit, component, API, contract and integration tests), with UI and end-to-end tests focused on critical user journeys rather than “testing everything through the UI”.

We practice a shift-left approach, involving QA from the earliest stages of feature planning. This ensures we maintain a user-centric perspective, influence implementation details when necessary, and distribute test coverage responsibilities among QA, frontend, and backend teams.
