The posting

ABOUT US

Sieve is a multi-modal lab curating the world's highest-quality training datasets — spanning video, audio, images, text, and 3D. We combine exabyte-scale data infrastructure and novel multimodal understanding techniques that push the frontier of foundation models. Video alone makes up 80% of internet traffic, and across modalities, data has become the enabling medium powering creativity, communication, gaming, AR/VR, and robotics. Sieve exists to solve the biggest bottleneck in the growth of these applications: high-quality training data.

We partner with top AI labs and did $XXM last quarter alone, as a team of ~30 people. We also raised our Series A from Tier 1 firms such as Matrix Partners https://matrix.vc/, Swift Ventures https://www.swift.vc/, Y Combinator https://www.ycombinator.com/, and AI Grant https://aigrant.com/.

WHY NOW

Sieve is one of the most capital-efficient teams in AI — roughly 30 people serving the world's leading AI labs across every major data modality. You'll join early, own problems end-to-end, and watch your work ship directly into the models defining the frontier.

ABOUT THE ROLE

As a product engineer at Sieve, you'll help build our video collection platform: a system that pays contributors for submitting video recordings alongside internal product tooling.

You'll work full-stack across frontend, backend, systems, and mobile to ship products quickly, improve reliability, and scale the platform in supporting millions of users. You'll also build internal tools that help the team source, review, and deliver high-quality data efficiently. You'll own projects end-to-end.

This role is ideal for someone who enjoys building products with tight feedback loops, thrives in a high-ownership environment, and wants to work directly on the core engine powering frontier video AI.

WHAT YOU’LL DO

- Build and scale a production product used by contributors, partners, and internal teams.

- Ship full stack features across frontend, backend APIs, and underlying systems.

- Ship mobile features that enable easy video capture and submission.

- Improve reliability, performance, and developer velocity across the platform.

- Build internal tools and workflows that make operations, QA, and delivery fast and consistent.

- Work closely with customers and operators to translate needs into product and ship iteratively.

REQUIREMENTS

- Strong full stack engineer who can take projects from idea to production.

- Strong TypeScript + modern frontend experience (React/Next.js preferred).

- Mobile experience in React Native, especially for media capture or upload flows.

- Backend experience in Python or Go, with solid API and database fundamentals.

- Comfort working across product and systems concerns (reliability, performance, observability).

- Clear communicator who works well with cross-functional stakeholders.

- High ownership and urgency, including willingness to work late nights and weekends when needed.

- In-person at our SF HQ

BONUS

- Experience as an early hire at a startup.

- History of shipping high-quality products with real users.

- Experience building simple tooling, including minimal internal APIs and Svelte dashboards

- Active GitHub or portfolio projects.

BENEFITS

- 401k + Full Health Insurance

- Breakfast, Lunch, and Dinner covered and your choice of snacks

- Ubers covered home

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
