• One XP team is an experimentation platform which support A/B Testing, Canary Releases and Feature Flag capabilities. We are seeking to onboard an Engineer for One XP platform.
• With One XP, you’ll have the ability to build technology products that shape the way that developers across American Express can setup and manage experiments and measure causal inference. We had an immense growth in terms of the number of onboarded experiments in 2021 and except that growth to continue/accelerate.
• One XP is an inner source platform and framework, we welcome contributions from Engineers across American Express, as a platform One XP provides all the required tooling for developers to setup experiments, promote them between different environments (dev/test/prod), visualize data points captured for the experiment.
• We are a distributed team with teammates across US time zones. We are at the fore front of inspiring change in terms of technology and culture across American Express.

As an Engineer on One XP team, you will:

• Build the infrastructure that allows for consistent and powerful causal inference across a highly scaled experimentation platform. You'll work directly with numerous teams across the company to improve Amex's rate of innovation though a better understanding of our users.
• Work across product and engineering teams to design and architect software at the innovative of experimentation and inference.  Understand our customer’s problems and balance their needs against methodological rigor to help move experimentation thinking forward at Amex.
• Develop sophisticated libraries and tooling to enable accurate and highly scaled analysis of experiment results.  Design and implement pioneering causal inference techniques and scale them across hundreds of experiments.
• Participate in all phases of software development from architecture/design through implementation, testing, and on-call.
• Work closely with Experimentation Data Science, Product and relevant engineering teams to solve challenging causal inference problems and build production grade implementations of those solutions.
• Drive “Experimentation Culture” at Amex. Be a part of leveling up experimentation and causal inference culture at Amex.
