Principal Engineer

Role Overview

• Lead and evolve the architecture of the N4 and EVP platforms for scalability, high-availability, integration, and security.
• Implement and enhance relational to no-SQL transformations, preferably Cassandra.
• Ensure robust performance and compliance, meeting the demands of mission-critical logistics operations in a high-velocity setting.
• Own the full lifecycle delivery from requirements through deployment and post-production support.
• Write production-grade code, build reusable frameworks, and implement complex business logic using Java, Spring Boot, Hibernate/JPA, Debezium, and Kafka integration.
• Test driven development to ensure automated unit and integration tests are carefully designed and implemented as part of the deliverables.
• Architect and maintain both traditional JEE stack, and event-driven, microservices-based architectures using Kafka, Spring Boot, and ActiveMQ (JMS).
• Ensure reliability, fault-tolerance, and message integrity in global deployments.
• Lead “war room” sessions to address distributed system failures, bottlenecks, deadlocks, and memory leaks using advanced debugging and profiling methods.
• Expert in database administration for SQL (PostgreSQL, SQL Server, and Oracle) and NoSQL (Mongo and/or Cassandra) platforms.
• Design and optimize highly available schemas for large-scale, high-concurrency transaction volumes.
• Guide and contribute to intuitive, data-rich user interfaces for logistics and terminal operators.
• Implement and promote best practices in authentication (OAuth2), encryption, and compliance (OWASP), safeguarding sensitive logistics data.
• Collaborate effectively with both senior and junior engineers, cross-discipline teams (US/India), QA, Product, and customers.
• Ensure high-quality documentation, efficient testing, and transparent progress reporting.
• Mentor and coach engineers of all levels; foster a collaborative, high-performance, and innovative team culture.

Requirements

• Bachelor's or master's degree in computer science or related discipline.
