Job Description

To consolidate and further develop its consultancy activities, 3E is looking for a Civil Renewable Energy Engineer, in the Barcelona office, where you will be working with our team of experienced experts who will be your continuous sounding board as you meet the needs of our customers.

You will work as a Civil Engineer, with your main focus on the different activities related to the design stage of a PV, BESS or Wind projects.

You will gradually grow into a full advisory coordinator role, being exposed also to other phases of a renewable energy project, including construction, operational activities, and technical due diligence.

At first your responsibilities will be to deliver civil technical drawings and calculation notes for the design of solar, BESS and Wind projects in and outside of Spain. Next to that, you will gradually evolve towards performing other technical assessments, either from the office or during site inspections.

Your main tasks will include:

  • Preparation of bills of quantities
  • Project constraint analysis using QGIS
  • Preparation of PV, wind, and BESS layouts based on manufacturer specifications
  • Perform site inspections before, during and after construction of the projects
  • Perform site inspections during the commissioning and operational phase of the projects.

As a consultant you will either work as an expert on a project managed by one of your colleagues or you will take the role of project manager yourself. As a project manager you are responsible for the communication with your client, potential other stakeholders and your colleagues, for managing the budget and planning of the project and for its timely and qualitative delivery.

Requirements

We are looking for a dynamic colleague who is eager to learn, who can bring an open and flexible mindset and who has very strong organisational skills.

  • Ideally you have a first working experience in Renewable Energy Project Design, Project Development and/or construction.

  • You have strong communication skills.

Of course, there are some non-negotiables:

  • You read, write and speak fluently in English and Spanish.
  • You have experience in civil design and design software (AutoCAD & CYPE).

What gives you extra points:

  • Software: PV Case, Civil 3D.
  • Other languages such as Italian are a plus!

We will make sure you are onboarded within our team, teaching you all in-and-outs of the role.
