SigOpt is an optimization service that helps customers find their best machine learning models. Our simple API makes suggestions to customers about different versions of their model to try, they evaluate those suggestions, and report back to us how well they did, so we can build our own predictions of what's going to make their model perform the best.

We are building out three major areas:

  • Optimization Engine intelligently finds model parameter suggestions using techniques like Bayesian optimization.
  • Simple API enables data scientists and machine learning practitioners to connect to our service within their existing machine learning pipelines
  • Experiment Insights web dashboard empowers researchers to introspect and reproduce experiments through the model development process.

Engineering at SigOpt

Engineering team and processes

We give engineers autonomy to make big decisions about what they're working on and how they want to ship it. An engineer leading a project scopes it out with the product manager, then collects input and feedback from the team. This project lead is responsible for choices in architecture, technology, and timeline.

We value code reviews, which we do on our private Github repositories. Code reviews give engineers an opportunity to learn from others, keep tech debt low, and gain confidence in their coding abilities.

We have thorough test coverage through unit, integration, and functional tests.

Technical Challenges

Implementing the computationally intense optimization techniques in a scalable, efficient way

Translating sophisticated optimization concepts into an easy to use API and web UI

Maintaining high reliability and availability for our demanding enterprise customers

Understanding and helping to shape the nascent workflow for ML model development

Visualizing high dimensional problem spaces for expert modelers

Building our backend in a flexible, understandable way so that our small team can iterate quickly

Projects you might work on
  • Orchestrate: Enable our customers to find their optimal model faster by embedding their training process into a docker image, and trying different parameter configurations in parallel in a kubernetes cluster.

  • Multimetric: Optimize two metrics simultaneously, for example the accuracy vs size of a deep learning model. Involves both research into how to sample a more complex space, and practical considerations of how to make visualizations and an API that customers can intuitively use.

  • Teams and Projects: Securely and easily group users or experiments together to share insights about experiments. Develop a permissioning model, APIs, and UI for a cohesive product release.

  • On Premises High Availability: Develop a set of Docker images that customers can deploy to their private cloud that minimize outages and provide a process to easily upgrade versions.

  • Deep Learning Experiments: Learn from intermediate results while training a deep learning model so that poor performing hyperparameters can be avoided, helping customers find optimal configurations for expensive models.
