SLNG is building the backbone for real-time speech AI, enabling developers to run voice applications anywhere in the world with local compliance and ultra-low latency.

Our founding team comes from the core of AI and developer tooling in the USA, with experience scaling platforms trusted by the world’s best builders.

We’re bringing the San Francisco mindset to Europe with our first hub in Barcelona, and we have the support of leading international VCs and Angel Investors who are backing our journey.

Challenge → Today, most speech infrastructure is US-centric, unreliable, and difficult to deploy globally. SLNG is changing that by delivering a platform that is:

• Local: deployed close to users and compliant with regional regulations.
• Fast: designed for real-time voice experiences.
• Open: built to integrate with the tools and workflows developers already use.

From real-time transcription to voice AI applications, SLNG is creating the Voice AI gateway that will empower the next generation of speech-powered products.

As an Ecosystem Engineer, you’ll work closely with Luke (Co-founder & CEO), connecting SLNG into the wider ecosystem.
