Systems engineers play an integral role in the success of businesses in many industries.
They lay the foundation or blueprint for systems to begin conception, production, and realization of valuable operations. The International Council on Systems Engineering (INCOSE) dates the origin of systems engineering back to World War II (1940s) at Bell Telephone Laboratories. Today, systems engineering is a process that includes identifying a problem based on consumer needs and developing a solution that is constantly re-evaluated throughout its execution. In short, systems engineers monitor the performance of systems and continually assess all stages of operations to ensure that a problem is solved.

The American Society of Mechanical Engineers reported that systems engineers’ possess an in-demand ability to apply an interdisciplinary approach to ensure technical needs are translated into step-by-step processes—in effect, producing efficient and effective results. A systems engineer will often collaborate with a project manager and the engineering team, and take the lead to translate between the two to facilitate the achievement of a successful system. The systems engineer will also work throughout each stage of the given system or process, from design and development to validation and operation, onto quantitative risk assessment, often focusing on performance, testing, scheduling, and costs. Due to the broad nature of the work, a systems engineer may work in virtually any industry, from software development and robotics, to nanotechnology or civil engineering.

Because of the type of work involved, not surprisingly, those who hope to pursue a career as a systems engineer should be highly proficient in math and science-related topics. Additionally, many systems engineers will be in near constant communication with engineering teams, project managers, and other stakeholders in the project. Ultimately, aspiring systems engineers should have highly developed interpersonal skills.

Systems engineering can be a truly rewarding field. Read on to discover what it means to be in systems engineering, including the common everyday tasks, typical employers, specializations, and the work environment.
