About the Role
Job Title: Software Engineer, Backend
Employment Type: Full-time
Department: Engineering
Overview:
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.
Responsibilities:
- Design and build core systems that power Soniox's real-time speech AI platform, focusing 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.
Qualifications:
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).
Benefits:
- Help build one of the most technically advanced AI platforms in the world and shape how it reaches and supports users globally.
- Work directly with a world-class team of engineers and researchers solving frontier problems in speech and language AI.
- Have a voice in how our company grows, how our customers succeed, and how AI transforms human communication.
