The largest engineering companies in the world (and their logos)

Largest Engineering Companies

The largest engineering companies in the world are masters of design, creativity, and innovation. This shines through not just in the incredible impact they have on the environment around us, but in the way they develop their visual brands.

Engineering company logos inspire customers, demonstrating expertise, authority, and reliability with colors, shapes, and fonts.

Similar to companies in any industry, the top engineering firms worldwide rely heavily on branding strategies to connect with customers and cultivate presence.

Through a compelling logo, an engineering brand can highlight its niche, differentiate itself from its competitors, and pave the way for rapid growth.

Whether you’re starting an engineering business of your own, and need inspiration to create your own iconic logo, or you’re simply interested in the branding strategies of famous engineering companies, you’re in the right place.

Today, we’re going to be looking at the brand strategies and logos of engineering companies that have made a lasting mark on the modern world.

The branding strategies of top engineering companies

Engineering is a broad and diverse landscape, packed with a host of different kinds of organizations, all dedicated to transforming the world we live in.

In the US alone, engineering services contribute around $600 billion in revenue to the economy, with different organizations focusing on a diverse range of sectors. The branding strategies of engineering companies tend to focus on highlighting the core mission or vision of the brand.

Shapes, symbols, and even colors can highlight the values of an electrical engineering company, renewable energy brand, or structural engineering venture. The diversity in the engineering landscape often means there’s a lot of variety in the logo design strategies teams use.

However, as you’ll see from the engineering company logos listed below, there are a handful of components that tend to play a crucial role in conveying brand identity:


Color psychology is essential to having a positive impact on any audience. Colors like blue and green convey ideas of reliability and growth, while shades such as red and orange highlight confidence and creativity.

The use of certain colors in the logos of engineering companies can help each brand connect with the right people.


Many of the top companies in the engineering landscape use wordmarks or acronyms in their logos. The right typography makes a huge difference to how people perceive a brand.

Sans-serif fonts show friendliness and modernity, while serif typefaces are more commonly associated with heritage and professionalism.

Shapes and icons

Imagery, whether in the form of simple geometric shapes, or complex designs, can also provide context into an engineering company’s services or niche.

Most organizations use globally recognizable shapes and components, to add depth to their logos, and capture the attention of customers.

In all cases, the best companies in the engineering space know how to utilize designs to showcase their skills, goals, and values in this broad landscape.
