At GrowthBook, we are building an open source feature flagging and A/B testing platform. If you love the data and engineering challenges faced by large tech companies, but want the ownership and flexibility of a small startup, then GrowthBook is for you.
We are a small all-remote team (mostly US based) backed by YCombinator and Khosla Ventures. We’re helping companies release code quickly and confidently while measuring the impact of what they launch. We are the largest open source feature flagging and A/B testing platform, and growing quickly.
As an open source company, we are focused on bottom-up adoption and building a product that engineers love to use. We have an amazing open source community on Slack that gives us constant feedback, feature requests, and ideas. GrowthBook is already used in production by hundreds of companies and we’re just getting started!
Some of the problems you'll be working on
- Real-time Feature Flag Analytics. When a developer pushes code live, they want to know two things right away - “Did I just break anything?” and “Is anyone using my new feature?”. APM tools like NewRelic only get you part of the way there and we want to build a truly comprehensive solution.
- Robust SQL Test Suite. We support 8 different SQL data sources, from Postgres to BigQuery to PrestoDB, and each of them have their own quirks and bugs that we need to work around. Supporting this at scale will require building robust automated test suites and provisioning complex cloud infrastructure on demand.
- Streaming Features Service. When someone toggles a feature flag in GrowthBook, we want it to propagate to all of their clients around the world within seconds. And we need to do this reliably (99.999% uptime) and at scale (billions of requests).

GrowthBook is an equal opportunity employer, and is committed to creating an inclusive, supportive environment for all employees.
We regret that we cannot sponsor new US employment visas at this time, although we can make exceptions for H1B transfers.

What We Do
GrowthBook is an open source feature flagging and A/B testing platform to help companies release code and measure the impact with their own data. Our platform gives any company the power of a customized release and A/B testing solution like those used by Netflix, Pinterest, Uber, etc. GrowthBook is an in-house flagging and experimentation platform you don't have to build.
Integration:
GrowthBook is warehouse native - we tie into your existing data infrastructure. We support most SQL based data sources, and even Google Analytics and Mixpanel. You can A/B test anywhere you can get data: web, mobile app, ML, email, etc.
Effectiveness:
Tools built based on best practices. Our SDKs support modern development processes, and are absurdly fast and easy to use. You can create a common metric store with SQL or YML. Our statistics engine is robust and understandable by non technical folks. We also give data teams full transparency into results- you can even export results as SQL or as a Jupyter notebook.
Documentation:
Searchable and shareable library of past tests. Capture institutional knowledge gained from experimentation. No more lost conversations or searching through Google Docs.
Data & Security:
User data never leaves the companies data infrastructure- you can even host it yourself. Compliant with PCI Data Security Standards
