Senior Backend Engineer

Scale is building out one of the largest hybrid human-machine systems. Scale’s self-regulating system automatically trains workers and ensures continuous quality and optimal allocation. We have thousands of human labelers that complete millions of tasks a month, and that comes with a host of interesting technical challenges. From product to systems to infrastructure engineering, we’re tackling it all to accelerate the development of AI.

Example projects

  • Use models to estimate the quality of tasks and labelers, and guarantee quality on requests at large scale.
  • Properly route tasks from customers to labelers for low turnaround and high accuracy.
  • Build methods to automatically measure and train labelers and optimally match labelers to tasks based on performance.
  • Build robust machine learning models to automate requests and improve our labelers’ efficiency.

This role could be a fit if you have:

  • 3-7+ years of industry experience as a software engineer post graduation
  • Systems engineering experience with real-time and distributed system architecture.
  • Experience building systems that process large volumes of data.
  • Experience or interest in using the following: AWS, Typescript, Node, Mongo, MLflow, Spark, Presto, Python (note that we are mostly language-agnostic and are open to using whatever is the best tech for the problem at hand)
  • Mentored and grown members of your team or been a tech lead on large projects
  • At least a Bachelor’s degree (or equivalent) in a relevant field.
