TMUS Global Solutions is a world-class technology powerhouse accelerating the company’s global digital transformation. With a culture built on growth, inclusivity, and global collaboration, the teams here drive innovation at scale, powered by bold thinking.

About the Role:

T – Mobile is transforming into a digital–first, AI-enabled, and data–driven organization, building modern platforms that power critical business functions at scale. A key focus area is evolving our Commissions systems into scalable, real–time, microservice–based architectures.

What You’ll Do:

• Design and develop scalable microservices for commission processing using Java and Spring Boot.
• Build and expose well – designed RESTful APIs for commission calculations, adjustments, and reporting.
• Decompose monolithic commission systems into loosely coupled, domain–driven microservices.
• Implement high – performance, low – latency services capable of handling high transaction volumes.
• Develop event–driven services using messaging systems (e.g., Kafka, RabbitMQ) where applicable.
• Optimize application performance through JVM tuning, concurrency handling, and efficient resource management.
• Ensure API reliability, versioning, and backward compatibility across services.
• Collaborate with product and business teams to translate commission rules into scalable service logic.
• Integrate microservices with downstream systems (databases, external APIs, financial systems).
• Implement observability (logging, metrics, tracing) for distributed systems.
• Support production systems through monitoring, troubleshooting, and performance tuning.

What You’ll Bring:

• Bachelor's degree in computer science, Technology, or related field, plus relevant years of experience in a related technical discipline.
• Familiarity with event–driven architecture and messaging systems (Kafka, RabbitMQ, etc.).
• Strong problem – solving, debugging, and system design skills.
• Effective communication and collaboration in global, cross–functional teams.

Must Have Skills:

• 4 + years of experience in Java development with strong core Java and JVM fundamentals.
• Hands – on experience building microservices using Spring Boot.
• Strong expertise in RESTful API design and development.
• Solid understanding of microservices architecture and distributed systems principles.
• Experience with concurrency, multithreading, and performance optimization in Java.
• Familiarity with event–driven architecture and messaging systems (Kafka, RabbitMQ, etc.).

AI & agent tooling:

• Proficient in AI coding/automation assistants (Claude, Copilot, or equivalent).
• Able to design, build, and deploy AI agents as first‑class platform components - agent‑driven CI/CD workflows, automated runbook execution, vulnerability triage automation, and developer self‑service tooling powered by AI.

Nice-to-Have:

• Experience in commissions, billing, or financial systems.
• Familiarity with Oracle databases or RDS in a microservices environment.
• Experience with Spring Cloud ecosystem (Config, Gateway, Open Feign).
• Knowledge of CI/CD pipelines and DevOps practices.
• Scripting experience (Python, Shell) for automation.
