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.
• Experience building or operating services on AWS or equivalent cloud platforms.
• Strong problem‑solving skills and a sense of ownership for delivered outcomes.

Nice to Have

• Experience in airline, cargo, logistics, or other complex enterprise domains.
• Familiarity with distributed systems, APIs, and event‑driven architectures.
• Exposure to CI/CD pipelines, automated testing, or infrastructure‑as‑code.
• Experience using AI‑assisted development tools to accelerate coding and debugging.

Why This Role Matters

SDE II engineers form the core delivery engine of FLX ONE Cargo. Your ability to build reliable features quickly—while steadily increasing technical depth—directly impacts delivery velocity and platform quality. Hands‑on C++ experience is required. Profiles without C++ development experience will not be considered.
