Senior Software Engineer (Backend)

We build infrastructure that delivers massive amounts of web data to the companies training the world’s most powerful AI models.

We're the team that helps to power and support Grass, a bandwidth-sharing network that lets us operate a massive distributed crawler, giving us unique access to high-quality public web data at global scale. On top of that, we’ve built pipelines for ingesting, segmenting, and annotating billions of videos, transcripts, and audio files, powering dataset creation for frontier labs.

We’re lean, technical, and move fast. No red tape, no slow decision-making; just a team of builders pushing to expand what’s possible for open web data and AI.

We are seeking a Senior Backend Engineer with deep expertise in backend development, particularly in data pipeline infrastructure. In this role, you will join a small, high-performing team to design and architect scalable systems, drive technical excellence, and help advance Grass’s role in shaping the future of the internet.

Deep expertise in designing, troubleshooting, and optimizing complex, live software systems.

Hands-on experience with modern development practices, including continuous integration and continuous deployment.

Strong analytical and problem-solving skills, particularly in diagnosing and resolving data flow and system performance issues.
