Sr Software Engineer I
About The Position
The Senior Software Engineer I role is part of Enterprise Architecture within the Chief Technology Office at American Express.

The role designs, develops, and delivers full-stack enterprise software and distributed systems, with Java and Python, and owns features from design through production deployment and support. It provides technical leadership within an Agile team, promotes engineering excellence and cloud-native practices, mentors junior engineers, and collaborates with architects, product managers, and cross-functional teams to deliver scalable, reliable solutions. American Express describes a culture shaped by its history, shared values, Leadership Behaviors, and commitment to customers, communities, and colleagues. The company offers support for colleagues’ well-being, learning, and career growth. The job posting gives a salary-range notice but does not provide the range itself.
