Sr Systems Reliability Engineer - Legal Technology

At T-Mobile, we invest in YOU!  Our Total Rewards Package ensures that employees get the same big love we give our customers.  All team members receive a competitive base salary and compensation package - this is Total Rewards. Employees enjoy multiple wealth-building opportunities through our annual stock grant, employee stock purchase plan, 401(k), and access to free, year-round money coaches. That’s how we’re UNSTOPPABLE for our employees!

The System Reliability Engineer (SRE) guides and mentors other SREs and improves and protects the software and systems behind T-Mobile's IT services, including scalability, availability, latency, performance, security, and capacity, while enabling faster, higher-quality software delivery.
In this role, you will support T-Mobile’s Legal & Emergency Response platforms—mission-critical systems that enable response to urgent law enforcement and emergency situations. These systems operate in high-stakes environments where reliability, speed, and accuracy truly matter. When these systems are up and running, they can help enable real-world outcomes that impact people in critical moments.
This is not a maintenance role. You’ll step into a modern, cloud-native platform that is still evolving—giving you the opportunity to shape how it scales, improves, and becomes truly resilient. You’ll work on meaningful problems, own production systems end-to-end, and directly influence how reliability is built into the platform.
You’ll also work in an environment that embraces modern engineering practices, including strong adoption of AI-assisted tools, and a culture that values ownership, collaboration, and continuous improvement.
If you’re someone who thrives in high-impact environments, enjoys solving complex reliability challenges, and wants your work to matter beyond just uptime metrics—this is a role where you can make a real difference.
