These Italian engineering services companies specialize in diverse fields, ranging from large-scale energy and infrastructure projects to advanced technology solutions. Many firms, such as Saipem, a global leader in energy and infrastructure engineering, and MAIRE, focused on energy transition technologies, operate internationally. Other significant players include Renco, which provides cost-effective solutions in energy and civil infrastructure, and CESI SpA, a technical consulting company in the energy sector.
A notable pattern among these companies is their strong presence in traditional industrial sectors like oil and gas, alongside a growing emphasis on renewable energies and sustainable solutions.

How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
