Join FiveNines as a Senior Engineer in Data Centre Construction

FiveNines is an international data centre infrastructure company that delivers complex, mission-critical projects across Europe. With a strong focus on safety, quality, sustainability and innovation, the company combines deep industry expertise with a collaborative approach to deliver world-class infrastructure projects. As a growing organisation, FiveNines offers an opportunity to work alongside industry experts and contribute to projects that help power the digital world.

As a Senior Engineer, you will play a key role in supporting the planning, coordination and delivery of civil, structural, concrete and underground utility packages throughout the project lifecycle. Working closely with clients, designers, subcontractors and project teams, you will help ensure that engineering solutions are practical, compliant, buildable and delivered safely while meeting project requirements.

In this role, you will coordinate technical interfaces across multiple disciplines, review engineering designs and technical submissions, support project planning and delivery, and contribute to solving complex engineering challenges. You will have the opportunity to influence project outcomes while working on some of the most demanding and technically interesting projects in the industry. You'll be part of an international business environment, with the opportunity to contribute both globally and, in the future, from Fivenine's Loviisa-based operations.

To succeed in this role, you should have a degree in Civil Engineering, Structural Engineering or a related field, together with several years of experience in civil, structural or infrastructure projects. Experience in data centre projects, utility infrastructure, concrete and foundations, or the Finnish construction industry is considered an advantage.

We are looking for a collaborative and proactive professional who enjoys solving technical challenges, working closely with different stakeholders and driving projects forward. Strong communication skills and the ability to thrive in a dynamic project environment will help you succeed in this position. We are looking for someone with good Finnish and English language skills.

At FiveNines, you will become part of an ambitious and highly skilled team that values capability, curiosity, collaboration, compliance and commitment. The company combines the agility of a growing business with the expertise and experience needed to deliver large-scale mission-critical projects. You will have the opportunity to develop your career in an international environment while contributing to projects that make a real impact.
