Sinch Telco is a standalone business within Sinch. Our products propel communications services for mobile operators and enterprises around the globe. We are looking for a Principal Software Engineer with focus on AI-driven Development, to accelerate adoption of AI-powered development practices across Sinch Telco.

In this role, you’ll be a hands-on practitioner, leveraging AI agents to design, build and deliver software while shaping how AI is applied in real engineering environments.
