Speechify is hiring a Software Engineer to join the Data side of its AI team. The company's mission is to make reading accessible to everyone through text-to-speech technology, serving over 50 million users across iOS, Android, Mac, Chrome, and web platforms. Recently recognized as Chrome Extension of the Year by Google and a 2025 Apple Design Award winner for Inclusivity, Speechify operates as a fully distributed, 100% remote company with ~200 employees globally. In this role, you'll own all aspects of data collection to support model training operations. You'll work on building high-quality datasets at petabyte scale while optimizing for cost and quality. Key responsibilities include: sourcing new audio data and integrating it into ingestion pipelines; operating and extending cloud infrastructure (GCP, Terraform-managed); collaborating with research scientists to optimize the cost/throughput/quality frontier; and helping shape the AI team's dataset roadmap for next-generation consumer and enterprise products. You'll need a BS/MS/PhD in Computer Science or related field, plus 5+ years of industry software development experience. Required skills: bash/Python scripting in Linux; Docker and Infrastructure-as-Code proficiency; hands-on experience with a major cloud provider (GCP preferred). Experience with web crawlers and large-scale data processing workflows is a plus. The ideal candidate is scrappy, adaptable to changing priorities, and communicates clearly. Speechify offers a fast-growing, entrepreneurial environment with a hands-off management approach, competitive salaries, and the opportunity to impact millions of users with accessibility-focused technology. The company emphasizes asynchronous culture, risk-taking, and hustle.
