Your tasks

About this role

As a Senior Fullstack Engineer (Java-Focused) in our Logistics team, you will be instrumental in enhancing and consolidating our 3rd Party Logistics (3PL) services. Your main contribution will be architecting the core back-end data flow and high-performance services. The React skills will be crucial for developing the necessary internal tooling and dashboards that manage our global delivery operations.

These are some of the key ingredients to the role:

• Backend Systems Leadership: Lead the development of critical, high-volume back-end components and RESTful APIs using Java, contributing to the potential migration of our Legacy 3PL service from .NET.
• Architecture & Best Practices: Apply your deep understanding of Event-Driven Architectures (EDA), microservices, and Domain-Driven Design (DDD) to build a scalable and maintainable core platform.
• Data Pipelining: Architect and implement robust data pipelines using Kafka or SNS/SQS to establish a unified, asynchronous messaging system for all 3PL interactions.
• Integration: Design and implement seamless integrations with internal APIs (e.g., Order-API, Restaurant-API) and external partner APIs, focusing on synchronous HTTP and asynchronous event-driven integrations.
• Logistics Focus: Bring your understanding of 3PL operations, delivery processes, and logistics metrics (e.g., Workload, ETA) to inform back-end design and feature development.
• Full Stack Accountability: Primarily focus on the back-end, but maintain the connection to the front-end, ensuring end-to-end reliability of the system.
• Frontend Support: Develop and maintain essential, responsive user interfaces and internal dashboards using React and TypeScript to effectively visualize data and manage logistics operations. The primary focus here is consuming back-end APIs for internal operational use.
• Performance: Optimize application performance on the back-end (Java services) and ensure the supporting front-end applications are highly functional.

Your profile

Are you a seasoned Software Engineer whose primary focus is building highly scalable, robust Java services and architecting core systems, but who also possesses the skills to deliver supporting user interfaces with React? Do you thrive in complex, data-intensive environments?

What will you bring to the table?

Core Skills (Must-Have)

• Messaging Systems (Primary): Deep understanding and practical experience with Kafka, including producers and consumers, and familiarity with other messaging systems such as SNS and SQS.
• APIs & Architecture (Primary): Proven ability to architect and implement complex RESTful APIs and integrate with external APIs, alongside practical experience with event-driven architectures and microservices.
• Frontend Capability (Secondary): Strong capabilities in web development, including React, TypeScript, and HTML5, sufficient for building and maintaining internal operational tools and dashboards that consume our core Java APIs. A solid understanding of CSS fundamentals is required.

Highly Valued (Bonus Points)

• Experience with a popular style component library (e.g., Material UI or Ant Design).
• Familiarity with module bundlers/build tools like Webpack or Vite.
• Practical experience using modern data fetching libraries such as React Query or SWR.
• A demonstrated focus on client-side application performance optimization for internal tools.
• Understanding of database concepts and experience working with various database systems.
