ppOur mission is simple: make AI voice relevant and available for the rest of the world. /p pWe usually respond within a day /p pSLNG is building the backbone for breal-time speech AI /b, enabling developers to run voice applications anywhere in the world with local compliance and ultra‑low latency. /p pOur 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. Meet bLuke /b, Founder CEO, and bIsmael /b, Founder CPO at SLNG. /p pWe’re bringing the San Francisco mindset to Europe with our first hub in bBarcelona /b, and we have the support of leading international VCs and Angel investors who are backing the SLNG journey. /p pChallenge → Today, Most Speech Infrastructure Is US-centric, Unreliable, And Difficult To Deploy Globally. SLNG Is Changing That By Delivering a Platform That Is /p ul liLocal: deployed close to users and compliant with regional regulations /li liFast: designed for real‑time voice experiences /li liOpen: built to integrate with the tools and workflows developers already use. /li /ul pFrom real‑time transcription to voice AI applications, SLNG is creating the Voice AI gateway that will empower the next generation of speech‑powered products. /p pAs bSpeech Model Performance Engineer /b, you’ll work closely with Ismael and the founding tech team to shape the technical foundation of SLNG. From TTS voices to multilingual ASR, you’ll benchmark, optimise, and productionize speech inference at scale. /p h3What We Offer /h3 ul liWe pay top of the market → We want serious talent in the team, and we benchmark compensation accordingly.
