The team owns the experimentation process end-to-end, driving Amazon's innovation cycle through rapid evaluation of ideas. The manager of this team is the single threaded owner of the experimentation process. ### Key job responsibilities Work backwards from customers. The experimentation leader is the single threaded owner of running randomized experiments at Amazon. The SDM must closely understand the customer problems to ensure we're working backwards from the most critical customer needs. Work closely with Science. Weblab is fundamentally a science and engineering product with neither able to operate at maximum effectiveness without the other. Relentlessly Prioritize. The team will receive far more asks for things to build and to support away teams than we can feasibly support. Trade off technical decisions. The team will be faced with high stakes technical tradeoff decisions. The SDM needs to listen to the opinions and recommendations of their tech leads while being able to make a clear decision. Manage large scale operations. The scale of the operations of the team is massive, both in terms of analyses run but also distinct teams and users. Small bugs can create massive headaches if they aren't caught or we don't have systems to detect issues and respond quickly. ### A day in the life Within the team we have a capable mix of developers at all points in their careers. The developers tend to be attracted to the hard scaling problems, and the complex user-experience required to guide people through statistical reasoning. The team also works closely with scientists who work on hard problems around causal inference and how to tease out quiet signals from a wealth of noise across disparate groups in Amazon. Weblab powers hundreds of thousands of experiments per year ran by tens of thousands of unique users each with their own needs and requirements. ### About the team Amazon’s Weblab team provides experiment based support to launch product changes, make product decisions, and evaluate the impact on customers. A/B testing is in Amazon’s DNA, and we are at the core of how Amazon innovates on behalf of customers. Be part of the team that helps Amazonians uncover the real impact of product changes to avoid accidental harm to customers or the business. ## At a glance - Posted by the employer: Sep 30, 2026 - First seen by OpenNash: Oct 11, 2026 - Last checked: Oct 11, 2026 - Listed for: 11 days - Location: US, WA, Seattle[Apply on Amazon’s careers site →](https://www.amazon.jobs/en/jobs/10564563/software-development-manager-weblab) ## More jobs at Amazon ### [AWS Software Development Manager, Elastic Load Balancing](https://jobs.opennash.com/companies/amazon/jobs/8bc81eb90a02a81cc9b1/) US, WA, Seattle ### [Applied Science Manager, Computer Vision, Perception Science, Prime Air Vehicle Software](https://jobs.opennash.com/companies/amazon/jobs/f8f3afcff56816849d13/) US, WA, Seattle ### [Developer Experience Engineer, AWS Developer Experience](https://jobs.opennash.com/companies/amazon/jobs/fbd46cd6cad9f0b7a4b1/) US, WA, Seattle ### [Developer Marketing Manager, Developer Marketing](https://jobs.opennash.com/companies/amazon/jobs/d8c4520c33f205cd0159/) US, WA, Seattle ### [Director of Software Development](https://jobs.opennash.com/companies/amazon/jobs/cff67c726a21a2a83042/) US, WA, Seattle ## Similar jobs at other companies ### [Software Development Engineer](https://jobs.opennash.com/companies/fortinet/jobs/28951e39aa65fab8d748/) Fortinet · Sunnyvale, CA, United States ### [Software Development Engineer (GUI)](https://jobs.opennash.com/companies/fortinet/jobs/bb39f255ec65bd5058b8/) Fortinet · Sunnyvale, CA, United States ### [Software Development Engineer II](https://jobs.opennash.com/companies/optimum/jobs/bdef493135bced9dff7b/) Optimum · Bethpage, NY, US ### [Software Development Engineer III](https://jobs.opennash.com/companies/optimum/jobs/3fea6604c9aa98bcc956/) Optimum · Bethpage, NY, US ### [Senior Embedded Software Development Engineer](https://jobs.opennash.com/companies/microsoft/jobs/47f921f9ea9b6ae753e9/) Microsoft · United States, Washington, Redmond [Jobs in Seattle, WA](/locations/us/wa/seattle/)[Jobs in Washington](/locations/us-wa/)[Software Engineering jobs](/functions/software-engineering/) OpenNash lists jobs from employers’ own careers sites and does not handle applications.
