The Opportunity:

Great software is more than a polished interface and data. It requires clean architecture, well-designed APIs, scalable infrastructure, thoughtful analytics integration, and disciplined execution from vision to production. We are seeking a senior technical leader who understands how to bring these elements together to deliver secure, user-focused, and production-ready systems in a fast-moving, agile environment.

You will analyze current environments, guide future-state architecture, and lead the implementation of scalable solutions that support evolving business needs.

Working closely with product, cloud, and data teams, you will help shape application strategy, improve engineering maturity, and deliver systems that create meaningful impact. Work with us as we shape systems for the better. Due to the nature of work performed within this facility, U.S. citizenship is required.
