About the role

At Soniox, our mission is to make voice universally accessible and programmable in real time. Our models depend on vast, diverse, and high-quality datasets to train state-of-the-art AI systems across languages and domains. As a software engineer working on data acquisition, you will lead the development of scalable infrastructure for acquiring, indexing, and managing data at massive scale — powering the next generation of speech and language models.

In this role, you will:

  • Design, build, and scale systems for web crawling, large-scale data ingestion, and content indexing.
  • Work closely with data processing and model training teams to ensure smooth and efficient data pipelines.
  • Own backend infrastructure for storage, indexing, and search across multi-petabyte datasets.
  • Architect distributed systems that are robust, performant, and optimized for research and production workloads.
  • Deploy and operate services in a Kubernetes environment using Infrastructure-as-Code.
  • Analyze system performance and data coverage through experimentation and instrumentation.

You might thrive in this role if you:

  • Have 6+ years of experience building large-scale software systems.
  • Have deep knowledge of distributed systems, web crawling, and backend engineering.
  • Are comfortable with key-value stores, data synchronization, and scalable storage systems.
  • Are pragmatic and curious — unafraid to try new tools and rethink old assumptions.
  • Communicate clearly and proactively, especially across cross-functional teams.
  • Care about building infrastructure that directly powers real-world AI systems.

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.
