We are looking for a highly driven Full Stack Developer to join our team and play a key role in building a next-generation logistics and shipping platform from the ground up. This is a high-impact opportunity for someone who enjoys solving real-world operational problems, building scalable systems, and taking complete ownership of product development in a fast-moving startup environment.

As a Full Stack Developer, you will work across frontend, backend, APIs, databases, and infrastructure to create a seamless logistics experience for customers. The platform will enable users to compare shipping rates, book shipments across carriers, make payments, generate labels, and track deliveries in real time through a unified dashboard.

This role requires strong technical depth, product thinking, and the ability to move quickly with minimal supervision. You should be comfortable handling multiple third-party integrations, designing scalable backend systems, and building intuitive client-facing experiences. Candidates who thrive in 0→1 product environments and enjoy building systems from scratch will excel in this role.

  • Participate in architecture discussions and contribute to long-term product scalability decisions
  • Troubleshoot production issues and optimize system performance continuously
