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:

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

Experience:

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