Guided by experienced leaders, Corporate Systems seamlessly integrate with advanced Technology and Operations to drive our enterprise forward. Our Systems Reliability and Software Delivery teams are unwavering in their commitment to excellence, ensuring every solution is robust and efficient. When you step into a career with AT&T, you won’t just imagine the future-you’ll create it.

What you’ll do:

In this role, you will focus on understanding why production incidents happen and how to prevent them from recurring. You will analyze incidents end-to-end across applications, infrastructure, and cloud environments, using observability data to identify root causes, patterns, and systemic weaknesses.

You will turn incident insights into high-quality postmortems and partner with engineering teams to drive corrective actions and long-term improvements. By combining system-level thinking with data, automation, and AI-assisted analysis, you will help shift the organization from reactive response to proactive reliability and incident prevention. You will partner with engineering and software development teams to implement permanent fix and preventive improvements

What you'll bring:

• Strong understanding of end-to-end system architecture (cloud, web apps, APIs, databases, infrastructure)
• Hands‑on experience with observability tools (logs, metrics, traces)

• Experience writing clear, structured postmortems
• Ability to analyze operational data using tools, queries, or AI-assisted methods
• Strong systems thinking and problem‑solving skills
• Background in QA, test engineering, or automation engineering (strong plus)
• Experience using AI or advanced analytics for incident analysis or pattern detection
• Understanding of distributed systems and failure modes
• Experience with data analysis / visualization tools (e.g., Power BI, Tableau)
• Mindset focused on eliminating recurring issues, not just fixing incidents
• Strong communication skills to explain complex issues clearly

Required:

• 7+ years in Systems Engineering, ITSM, RM/CM
• Background in SRE, Support or QA
• One or more of the following SRE Tools: T-APM, T-Trace, CatchPoint, Grafana
• Hands‑on experience and understanding of concepts and tools such as SAFe, Agile, DevOps, CI/CD, Data Analytics, and building Gen AI use cases
• Experience with AI technologies, Python, SQL, data analytics, Power BI and ITSM tools (e.g., ServiceNow)
• Modern Enterprise Release Management/Change Management and ITSM

Preferred:

• BS/BA in Computer Science
• Preferred tools: modern Release Management processes for Agile and DevOps environments
• Jira Align, JSM, Jira Cloud, Git for enterprise RM/CM
• Relevant certifications (SAFe, Agile, DevOps, AI/ML)

Joining our team comes with amazing perks and benefits:

• 401(k) plan
• Paid Time Off and Holidays (based on date of hire, at least 23 days of vacation each year and 9 company-designated holidays)
• Paid Caregiver Leave
• Additional sick leave beyond what state and local law require may be available but is unprotected
• Adoption Reimbursement
• Disability Benefits (short term and long term)
• Life and Accidental Death Insurance
• Supplemental benefit programs: critical illness/accident hospital indemnity/group legal
