ABOUT THE ROLE:
The Staff Engineer, Domain Architect PMT is the most senior individual contributor on the India-based PMT operational engineering team. The role provides cross-portfolio architectural leadership across all PMT applications - HR systems (Workday, UKG, Learning, and adjacent platforms), DevOps and platform tooling, and automation/AI initiatives.
This role mirrors T-Mobile's US-based Staff Domain Architects, providing architectural continuity and partnership across geographies. The Domain Architect partners with the Manager SRE on team direction, with US-based Domain Architects on portfolio-wide patterns, with US-based Software Developers (DevOps) on platform tooling direction, and with all India engineers as a technical mentor and design reviewer.
This is a forward-looking role: as T-Mobile transitions from SaaS-heavy to custom-built platforms over the next several years, the Domain Architect shapes the engineering standards, integration patterns, and reliability frameworks that the team will build against.
WHAT YOU'LL DO:




- Define and evolve architecture standards across the PMT application portfolio - integration patterns, observability conventions, automation frameworks, security posture.
- Review and guide significant technical designs from the SRE, DevOps/Platform, and Automations & AI pods.
- Partner with US Domain Architects on SaaS-to-custom migration patterns; partner with US Software Developers (DevOps) on platform and CI/CD direction.
- Provide hands-on technical mentorship to engineers across all India pods; raise the engineering bar through code review, design review, and pairing.
- Own architectural decision records for cross-portfolio choices (e.g., common observability stack, identity integration patterns, automation framework selection).
- Identify and lead targeted proof-of-concept work that de-risks the broader Phase 2 build direction.
- Represent India engineering perspective in T-Mobile architecture forums and standards discussions
