You will likely be involved in projects that require data-driven decision-making, such as tracking material consumption, monitoring machinery maintenance schedules, or managing project documentation. Your ability to integrate into a site-based culture is just as important as your coding ability; you will often find yourself discussing technical requirements with engineers who are managing the physical construction, making clear communication a daily necessity.
