Job description

Our current technology stack forms the foundation of our work. Proficiency or strong experience in the following areas is highly desirable:

Java: Deep understanding of Java (latest LTS versions preferred).

Spring Boot: Extensive experience building applications and microservices using the Spring Boot framework and its ecosystem (e.g., Spring Data, Spring Security, Spring Cloud).

Messaging Systems:

Apache Kafka: Solid understanding of Kafka concepts (topics, producers, consumers, partitioning, brokers) and experience building event-driven systems.

Containerization & Orchestration:

Kubernetes: Practical experience deploying, managing, and troubleshooting applications on Kubernetes.

OCP (OpenShift Container Platform): Experience specifically with OpenShift is a significant advantage.

AKS (Azure Kubernetes Service): Experience with AKS is also highly relevant.

(General Docker knowledge is expected).

CI/CD & DevOps:

GitHub Actions: Proven experience in creating, managing, and optimizing CI/CD pipelines using GitHub Actions for build, test, and deployment automation.

Understanding of Git branching strategies and DevOps principles.

Frontend Development:

React: Experience building user interfaces with the React library and its common patterns/ecosystem (e.g., state management, hooks).

Database & Data Warehousing

Oracle: Experience with Oracle databases, including writing efficient SQL queries, understanding data modeling, and potentially PL/SQL.

Snowflake: Experience with Snowflake cloud data warehouse, including data loading, querying (SQL), and understanding its architecture.

Scripting:

Python: Proficiency in Python for scripting, automation, data manipulation, or potentially backend API development (e.g., using Flask/Django, though Java/Spring is primary).

While not strictly mandatory, candidates with experience or a demonstrated understanding of the transportation and logistics industry (e.g., supply chain management, freight operations, warehousing, fleet management, routing optimization, TMS systems) will be able to contribute more quickly and effectively. They can better grasp the business context and user needs.

Additional Valuable Skills

We are also interested in candidates who may possess skills in related areas that complement our core activities: Data Science & Analytics.
