T-Mobile is synonymous with innovation–and you could be part of the team that disrupted an entire industry! We reinvented customer service, brought real 5G to the nation, and now we’re shaping the future of technology in wireless and beyond. Our work is as exciting as it is rewarding, so consider the career opportunity below as your invitation to grow with us, make big things happen with us, above all, #BEYOU with us. Together, we won’t stop!

Get hands-on experience, training—and a leg up on a bright future.

T-Mobile didn’t become a leader by following the playbook. We got here by breaking it. We’re a disruptor that now plays on a higher tier, and we’re still raising the bar for millions of customers nationwide. If you want to work somewhere that sets the standard instead of matching it, this is your place.

This is an 11-week paid learning experience where you’ll do real work, not busywork. You’ll build relationships with other interns and leaders across the company, and you’ll be paired with mentors who will challenge you to grow skills that matter. We’ll give you hands-on projects with real stakes, and we expect your creativity and sharp ideas to make an immediate impact. You’ll work alongside T-Mobile employees who have your back and who still believe the best ideas can come from anyone.

What It’s Like

Our Site Reliability Engineering (SRE) team keeps T-Mobile’s business-critical systems reliable, available, and fast. We’re small enough that you’ll be seen and heard, and big enough that your work matters. A typical week mixes hands-on building (scripts, dashboards, alerts) with digging into system metrics and logs, joining incident investigations, and swapping ideas with SRE and engineering partners. You’ll work alongside experienced engineers who will push you to learn fast and own your work.

What You’ll Do

You’ll help improve infrastructure monitoring, automation, and system reliability across T-Mobile’s critical services. By building dashboards, automating manual work, and analyzing system performance, you’ll help us catch issues before they reach customers and keep delivering the seamless digital experiences people expect from the Un-carrier.

Key Responsibilities

• Build and enhance monitoring dashboards, alerts, and observability solutions that proactively surface infrastructure and application issues
• Develop Python or Bash scripts that automate repetitive operational tasks and reduce manual effort
• Analyze system metrics, logs, and performance trends to identify reliability risks and recommend improvements
• Support incident investigation, troubleshooting, and root cause analysis, and document operational procedures
• Partner with SRE and engineering teams on capacity planning, infrastructure performance, and continuous improvement initiatives

What It Takes

You’re curious, you challenge assumptions, and you move with urgency when something breaks. You bring a foundation in Linux/Unix, networking, and cloud computing, plus basic scripting experience in Python, Bash, or similar languages. Familiarity with AWS and observability tools such as Grafana, Prometheus, or Splunk is a plus, as are CI/CD, Git, containerization (Docker, Kubernetes), and infrastructure-as-code (Terraform). You’re a sharp problem-solver and a clear communicator who takes ownership, pays attention to detail, and learns quickly. Hands-on experience from academic projects, internships, personal projects, open-source work, technical clubs, or hackathons will help you stand out. AWS Cloud Practitioner or Solutions Architect Associate certifications are a plus but not required.

Minimum Qualifications

• At least 18 years of age
• Legally authorized to work in the United States now and in the future
• Must have one or more course(s) remaining in a Bachelors or Graduate degree program post internship
