This role supports the Mechanical Technology team responsible for systems that maintain rolling stock assets (locomotives and rail cars) and high-volume detector/IoT sensor platforms. The engineer will modernize legacy microservices, scale event-driven architectures, refactor rules engines, and build cloud-ready systems that handle large operational data flows. The work is backend-heavy with full-stack ownership.

Responsibilities:

1. Modernize and refactor legacy microservices and distributed systems.
2. Design and scale event-driven architectures using Kafka.
3. Build backend services in Java/Spring Boot and support Python-based data workflows.
4. Develop cloud-native solutions (AWS preferred) and apply cloud-agnostic patterns.
5. Support both new development and existing production systems.
6. Work with high-volume IoT/detector data and relational databases (Postgres).
7. Implement DevSecOps practices: CI/CD, automated testing, secure coding.
8. Collaborate across Mechanical and Hub/Terminal teams.
9. Provide mentorship and technical leadership to junior developers.
10. Contribute to full-stack delivery, including occasional frontend support.

Experience:

1. 6+ years of full stack development experience (backend-heavy).
2. Deep expertise in Java (all versions) and Spring Boot.
3. Strong event-driven architecture background; Kafka required.
4. Hands-on modernization experience with legacy microservices.
5. Cloud experience (AWS preferred; Azure acceptable).
6. Python for backend/data workflows.
7. Experience with Postgres or other relational databases.
8. IoT, detector systems, or high-volume data pipeline experience.
9. DevSecOps mindset and automated engineering practices.
10. React or Angular nice to have.
