Role Context As a Software Engineer (SDE II) – Backend (C++), you are a hands-on engineer building core backend and system-level components for FLX ONE Cargo (F1C). This role focuses on developing strong foundations in C++ systems development, performance, and reliability.

You will work closely with Senior Engineers and Tech Leads to build production-grade services, while developing deeper understanding of concurrency, memory management, and efficient system design. This is a code-first role.

You are expected to actively contribute to backend systems, solve technical problems, and progressively take ownership of components as your experience grows. Hands-On Development • Design and implement backend services and components using modern C++. • Work on system-level concerns including performance, memory usage, and concurrency.

• Contribute to building scalable, efficient, and reliable backend modules. Feature Ownership • Take ownership of end-to-end feature delivery—from implementation through testing and production rollout. • Translate requirements into clean, maintainable, and scalable code.

• Apply modular design principles to support independent evolution and future migration paths. Quality & Reliability • Write unit and integration tests to ensure correctness and prevent regressions. • Participate actively in code reviews, incorporating feedback to improve code quality.

• Contribute to observability and operational readiness of the services you build. Learning & Growth • Learn system design, cloud patterns, and operational practices through real production work. • Pair with senior engineers to deepen technical judgment and problem-solving skills. • Actively seek feedback and continuously raise your engineering bar.

What You Must Bring • 3+ years of professional software development experience. • Strong proficiency in C++ with experience building backend or system-level components.
