Job Description

Who are we?

We are a young company with a long previous track record and currently in a growth phase.

At Quark, we design infrastructures to digitally connect the world in a secure, efficient, and sustainable way; developing engineering, PM/CM, and consulting services.

Today, we design the data centers of the future.

We are currently growing in large-scale Data Center projects and are looking to incorporate an Electrical Site Engineer who wants to be on the front line of execution.

We are talking about projects where technical precision, quality, and reliability are non-negotiable. And where your role will be key to turning the design into an operational reality.

You will work directly on-site, in permanent coordination with design teams, contractors, and the client.

What is the environment like?

You will be part of a highly specialized Data Center team within QUARK (Sener), participating in demanding and large-scale projects.

You will have direct contact with the reality of the site and with all project stakeholders: from design to commissioning.

Additionally, you will have:

High-level technical environment
Accelerated learning in complex projects
Internal support and mentoring.
Progressive growth toward roles with more technical autonomy

What will you do?

You will be the person responsible for ensuring that electrical installations are executed exactly as they should be: with quality, safety, and technical coherence.
Your day-to-day will be closely tied to the site:
- You will supervise the execution of electrical installations in Data Centers (MV/LV, UPS, generator sets, panels, conduits, etc.).
- You will review layouts and coordinate with other disciplines to avoid interferences.
- You will detect deviations and propose viable technical solutions on-site.
- You will participate in the validation of equipment, materials, and submittals.
- You will provide technical support for incidents and contractor queries.
- You will ensure regulatory compliance (REBT, IEC, quality, safety...).
- You will accompany the testing, start-up, and commissioning phases.
- You will collaborate in the review of final documentation (As Built, protocols, certificates...).
It is a very comprehensive role, with a real impact on the final result of the project.

What do you need to fit in?

We are looking for a person with a solid technical base and judgment in a site environment:
- Electrical / Industrial Engineering or similar.
- Between 3 and 5 years of experience in electrical installations.
- Experience in site supervision or technical assistance.
- Knowledge of MV/LV electrical systems.
- Ability to interpret plans, diagrams, and specifications.
- Good level of English (you will work in an international environment).
- Ability to coordinate with multiple stakeholders.
💡 Highly valued:
- Experience in Data Centers or critical infrastructures.
- Experience in commissioning.
- Knowledge of standards (Uptime, TIA, IEC...).
- Proficiency in BIM / AutoCAD / Navisworks tools.

What are our benefits?

These are some of the benefits you will enjoy:

Join a multidisciplinary and highly qualified team participating in technologically innovative projects on an international level.
Continue your professional development with us and access a wide range of training (technical, skills, languages...).
Take care of yourself with our physical and emotional well-being program: sports, workshops, medical service, physiotherapy, etc.
Optimize your salary with our flexible remuneration plan (meal card, private health insurance, nursery vouchers...) and rely on our life and accident insurance.
Discount portal for you and a specific onboarding plan for our international employees.
We promote equal opportunities, diversity, and inclusion for all people and are certified as a Family Responsible Entity (efr). Additionally, through the Sener Foundation, we collaborate in activities that encourage the pursuit of knowledge and contribute to the socially responsible development of engineering.

We offer you the chance to be part of an environment in full expansion, with access to strategic projects and a long-term career path.

The professional evolution of technical profiles does not imply leaving engineering: we encourage trajectories where deep knowledge and technical experience remain the central axis of development.
