The Opportunity

The Developer III leads complex, cross program software projects and sets technical direction across multiple initiatives. As a senior full stack engineer and solution architect, you will mentor teams, establish best practices, and deliver advanced, scalable, cloud native solutions with a strong emphasis on DevSecOps, performance, accessibility, and reliability on AWS. This role is pivotal in driving architectural decisions, modern CI/CD execution, and SRE practices for mission critical systems.

You will operate as the senior technical authority within Agile delivery, shaping cloud architectures, microservice patterns, and security controls while guiding teams to high quality releases.
