About The Position

The System Reliability Engineer (SRE) improves and protects the software and systems behind all of T-Mobile's IT services, including management of scalability, availability, latency, performance, security, and capacity, and delivery of software faster, better, and cheaper. From designing & maintaining CICD Pipelines to building the next generation of T-Mobile applications on cloud native platforms, the SRE's enable great customer experience and product innovation by continuous improvement of operational support. We pride ourselves on encouraging a culture of innovation, advocating for agile methodologies, and promoting transparency in all that we do. Join us in embodying the spirit of the 'Un-carrier' and make a tangible impact! Driving the Next Evolution of Access Governance The Compliance Campaign Management (CCM) team within T-Mobile's Identity Security and Access Management (ISAM) organization is leading a major transformation in logical access compliance. What was once a predominantly manual User Access Review process is rapidly evolving into a sophisticated, automation-driven platform powered by cloud technologies, APIs, workflow orchestration, and artificial intelligence. Our team designs and builds solutions using Power Platform, Azure DevOps Pipelines, Microsoft Graph APIs, and AI-powered automation to streamline compliance operations while expanding risk visibility across the enterprise. Every innovation we deliver helps reduce manual effort, strengthen control effectiveness, and improve audit readiness. As CCM continues to scale, we're creating an environment where human expertise and AI agents work side by side to execute compliance operations with greater speed, consistency, and precision. To support this evolution, we're seeking an SRE who will own the reliability, observability, and continuous improvement of our compliance automation ecosystem. In this role, you'll ensure our automation platforms remain highly available, performant, secure, and audit-ready, enabling critical compliance processes to operate seamlessly across the enterprise. Join a team that's not just supporting compliance but engineering the future of access governance. You'll have the opportunity to solve complex technical challenges, influence enterprise-wide security outcomes, and help build the intelligent automation capabilities that will define the next generation of compliance at T-Mobile. If you're excited by the intersection of automation, cloud engineering, AI, and cybersecurity, you'll play a key role in transforming how access risk is identified, reviewed, and remediated at scale.
