About Labelbox

Labelbox is building software infrastructure for industrial data science teams to do data labeling for the training of neural networks. When we build software, we take for granted the existence of collaborative tools to write and debug code. The machine learning workflow has no standard tooling for labeling data, storing it, debugging models and then continually improving model accuracy. Enter Labelbox. Labelbox's vision is to become the default software for data scientists to manage data and train neural networks in the same way that GitHub or text editors are defaults for software engineers.

Current Labelbox customers include American Family Insurance, Lytx, Airbus, Genius Sports, Keeptruckin and more. Labelbox is venture backed by Andreessen Horowitz, Gradient Ventures (Google’s AI-focused venture fund), Kleiner Perkins, and First Round Capital and has been featured in Tech CrunchWeb Summit and Forbes.


We are looking for a Senior Frontend Engineer to join the Perception Team. The team’s mission is to build the most efficient tool for machine learning and computer vision teams to turn assets into high quality training data. Our customers use what we create to make breakthroughs in their fields and industries, and advance artificial intelligence. We will do this by building a tool that the customer can depend on and enjoy using with problem-focused craftsmanship, rooted in our customers.

Our team specializes in processing all kinds of multimedia assets and developing innovative, reliable, and desirable annotation editors - all through a performant, efficient, and beautifully designed browser interface served to a globally-scaled workforce. As a team, we develop all over the stack and system, but our most critical expertise lies in our experience and proficiency with modern browser and graphics technologies.

We believe that AI has the power to transform every aspect of our lives -- from healthcare to agriculture. The exponential impact of artificial intelligence will mean mammograms can happen quickly and cheaply irrespective of the limited number of radiologists there are in the world and growers will know the instant that disease hits their farm without even being there.

At Labelbox, we’re building a platform to accelerate the development of this future. Rather than requiring companies to create their own expensive and incomplete homegrown tools, we’ve created a training data platform that acts as a central hub for humans to interface with AI. When humans have better ways to input and manage data, machines have better ways to learn.
