Senior Java Developer - N4F
We're looking for a strong Senior Java Engineer to help build and modernize Deutsche Telekom's network management and provisioning ecosystem.
This is not a typical enterprise CRUD environment!
Our systems support large-scale telco infrastructure and services including:
- 5G rollout
- FTTH / FTTC broadband provisioning
- IP Transit services
- distributed network orchestration
- machine-to-machine communication workflows
You'll work on backend platforms where scalability, resilience, distributed communication, and reliability are real engineering challenges — not just buzzwords.
The role focuses on designing and developing modern Java microservices for provisioning, orchestration, and complex system integrations in a mission-critical telco environment.
What you'll work on:
- Designing and developing Java-based backend microservices
- Building scalable distributed systems
- REST and event-driven communication
- Network provisioning and orchestration workflows
- PostgreSQL modeling and optimization
- CI/CD pipelines and containerized environments
- Kubernetes / Docker infrastructure
- Integration of complex business and network management systems
- Technical mentoring and architecture reviews
- Helping modernize legacy telco platforms into modern distributed architectures
Tech Stack:
- Java
- Microservices
- REST APIs
- PostgreSQL
- Docker
- Kubernetes
- CI/CD
- Event-driven architecture
Qualifications:
- Strong experience in Java development and microservice architectures
- Expertise in RESTful API design, and event-driven communication (Stargate, Horizon)
- Solid experience with PostgreSQL (data modeling, queries, optimization)
- Ability to design and review software architecture for distributed systems
- Familiarity with CI/CD pipelines and containerization (Docker, Kubernetes)
- Strong analytical and conceptual skills for system design
- Leadership qualities and experience in guiding development teams
- Willingness and capability to integrate AI solutions for process optimization and workflow improvement
