Join our team as Software engineer, backend Ljubljana, Slovenia Apply now About The Role Soniox is building the future of speech AI — real-time transcription, translation, and reasoning across 60+ languages, delivered through a single, low-latency API. As we scale rapidly, we're looking for experienced engineers who love solving deep technical problems and building world-class infrastructure. You’ll work in a fast-moving, collaborative environment where we ship often, optimize relentlessly, and care deeply about reliability. Our technology powers real-time voice interfaces, multilingual communication, and next-generation AI products used by developers around the world. In This Role, You Will Design and build core systems that power Soniox's real-time speech AI platform, with a focus on scalability, performance, and security. Collaborate with engineers, researchers, and product teams to bring new speech capabilities to market — and push the boundaries of what’s possible in real-time voice AI. Develop internal tools and infrastructure that boost engineering velocity and system robustness. Own the full lifecycle of your work — from design to deployment to on-call operations — with a strong sense of responsibility and autonomy. You Might Thrive At Soniox If You Have built and scaled production systems, ideally involving real-time data, distributed infrastructure, or machine learning pipelines. Care about quality and user experience — and take pride in building things that just work. Are hands-on, humble, and willing to dig into unfamiliar parts of the stack to solve real problems. Automate your way out of repetition, and know when to reach for existing tools vs building your own. Enjoy working in a startup environment where speed, ownership, and impact matter. Have been a founder or early engineer at a high-growth company (a plus, not a requirement). Why Soniox You’ll help build one of the most technically advanced AI platforms in the world — and shape how it reaches and supports users globally. You’ll work directly with a world-class team of engineers and researchers solving frontier problems in speech and language AI. You'll have a voice in how our company grows, how our customers succeed, and how AI transforms human communication. Ready to join Soniox?
