The Differences Between a Software Engineer and a Systems Engineer

Updated: Nov 13, 2023

Systems engineering and software engineering are both important technological disciplines. Although their roles and responsibilities vary, system and software engineers work towards common goals and objectives. The best way to identify the key differences is by acquainting yourself with their roles, methodologies, and target results. This article will outline the main differences between systems and software engineers:

A Software Engineer & a Systems Engineering Working on a Project

What is Systems Engineering?

Systems engineering has to do with the process of developing and refining systems and processes. Systems engineers' main role is to analyze system challenges and develop the best solutions. Some of the responsibilities of systems engineers are:

  • Teaming with systems architects to perform various organizational duties.

  • Calculating and assessing all technical features to ensure all systems are in good working condition.

  • Creating test plans to develop computer systems.

What is Software Engineering?

Software engineering is the practice of analyzing users' requirements and building, designing, and testing applications that can be used to meet and satisfy these requirements. The responsibilities of a software engineer include:

  • Updating software

  • Developing software code from scratch to meet user's needs

  • Building and improving on already existing software to enhance customer experience.

Key Differences Between Software Engineers and Systems Engineers

Now that you know some of the duties of a systems engineer and a software engineer, here are some of the key differences between them.


Systems engineers manage the entire project lifecycle using an interdisciplinary approach to transform requirements into solutions. The methods used include:

  • Interface specification

  • Configuration management

  • Design tradeoffs

  • Stakeholder analysis

On the other hand, software engineers are concerned with software development, control, infrastructure, databases, and applications. They use the following methods:

  • Process modeling

  • Agile methods

  • Continuous integration

  • Incremental verification and validation

Daily Tasks and Job Description

The daily life and tasks of systems and software engineers are entirely different. Software engineers will spend most of their day attending meetings, coding, and teaming up with colleagues to achieve a common goal. A systems engineer, on the other hand, does not spend their day coding. Rather they will manage organizational systems and infrastructure and ensure they function optimally.


Although these two careers are somewhat connected, their educational backgrounds differ. A systems engineer's broader background includes mathematics, computer science, or engineering. A software engineer has a background in a more technical background in fields such as computer science or computer engineering.

Skills Set Required

Another key difference between systems and software engineers is the requisite skill set. A systems engineer needs to possess skills like:

  • Problem-Solving

  • Programming

  • Communication

  • Customer Services

On the other hand, software engineers require the following:

  • Programming Skills

  • Experience in Building Software Packages

  • Familiarity With UI Toolkits and Frameworks

  • Troubleshooting and Debugging Skills

End Project Goal

Systems engineers focus more on domains, users, and user experiences, while software engineers focus on developing and ensuring the applications' usability.
