Requirements
  • Excellent communication skills
  • Deep passion for the video domain and media technologies
  • Motivated by building end-to-end products—not just training models
  • Able to break problems down from customer level impact to necessary building blocks.
  • In-person at our SF HQ
Responsibilities
  • Help build high performance building blocks and large scale pipelines to understand video with high precision at internet scale.
  • Often this involves working on ambiguous research problems and finding clever techniques to solve them.
  • You will be working in the computer vision, audio processing, and text processing domains.
  • You’re likely a good fit if you’re comfortable working with models + APIs and squeezing every drop of performance out of them through clever pre/post-processing, parallelism, pipelining, inference optimization, and occasionally fine-tuning.
Desired Qualifications
  • Bonus: Active contributor to open source projects

SieveData runs a cloud-based AI platform for building and deploying custom video and audio applications, providing ready-made models and the deployment infrastructure so product teams can create and own AI-powered features with just a few lines of code. Developers use APIs to integrate capabilities like video cropping, translation, transcription, and noise removal, while each app includes an auto-generated playground for testing and collaboration; the system scales automatically as traffic grows. It differentiates itself by pairing usable AI models with end-to-end infrastructure and an emphasis on ownership, plus per-app playgrounds and automatic scaling to support rapid collaboration. The goal is to help product teams quickly build, test, and deploy scalable, cost-visible video and audio AI features.

Simplify's Take

What believers are saying

  • Sieve says many leading AI labs and Fortune 100 companies already buy from it.
  • The March 2026 repositioning aligns with surging demand for training-ready multimodal data.
  • Billions of videos and custom environments support higher-value contracts and sticky enterprise renewals.

What critics are saying

  • The 2026 pivot killed the original developer API business, alienating the startup market.
  • Competitors like Twelve Labs, Mixpeek, and Primate Vision own video-intelligence buyers now.
  • Dataset sourcing depends on licensing partners; any rights dispute or supply shock breaks delivery.

What makes Sieve unique

  • Sieve now sells multimodal data, not APIs, targeting frontier labs and Fortune 100 teams.
  • Its own collection platform and licensing partnerships feed billions of videos into training datasets.
  • Custom dataset and environment delivery in days gives Sieve faster procurement than manual sourcing.
