Linux Application Engineer – Terminal Automation

Our client is a major container terminal operator at the Port of Antwerp — one of Europe's busiest logistics hubs. Their semi-automated terminal runs 24/7, moving thousands of containers using automated stacking cranes, remote-controlled quay cranes, and real-time control systems. When software fails here, vessels wait and productivity stops.

• Act as 2nd-line support for terminal applications across yard operations, crane automation, equipment communication, and gate systems.
• Perform live debugging in a 24/7 production environment — analysing logs, core dumps, and system behaviour to restore service within SLA.
• Maintain and improve Linux-based applications supporting Terminal Operating System integrations, equipment control, and middleware interfaces.
• Develop software modifications in C, C++, and Python to improve concurrency, memory handling, and performance.
• Profile production bottlenecks using perf, valgrind, and gdb — then fix them structurally, not temporarily.
• Support controlled deployments and CI/CD processes using GitLab or Jenkins.
• Apply secure coding practices and Linux hardening measures (AppArmor, SELinux) in a critical infrastructure environment.

• You have 5+ years of experience in Linux software development.
• You bring 3+ years of knowledge in C and C++ development.
• You possess a deep understanding of multithreading and concurrency concepts.
• You have experience debugging production systems using perf, valgrind, or gdb.
• You're proficient in networking fundamentals including TCP/IP and socket programming.
• You possess experience with Git-based workflows and build systems like CMake or Make.
• You're analytical, solution-oriented, and able to remain calm under high operational pressure.
