Supportive Leadership, Collaborative Engineering
Pros: I've really appreciated the clear direction from the leadership team here at Deerns. They're transparent about company goals and empower project teams. The collaborative environment among fellow MEP engineers is fantastic, and I've learned a lot from senior colleagues. There's a strong focus on technical excellence in building services, and I feel my contributions are valued. The international engineering consultancy framework provides exposure to diverse projects.
Cons: While leadership is generally strong, communication on project scope changes could be more streamlined, especially for complex international engineering projects. Sometimes, during peak workloads, the approval processes can feel a bit slow, impacting project timelines slightly. Career progression paths for specialist roles could also be made clearer.
Advice to Management: Continue fostering open communication channels, especially regarding project adjustments and career development. Look into optimizing approval workflows during busy periods to maintain project efficiency.

Good projects, supportive teams, room for growth
Pros: I've had the chance to work on some really engaging projects related to sustainable building design and energy efficiency, which is great for professional development. The team atmosphere in the Paris office is usually quite positive and helpful. There's a good sense of camaraderie and mutual support among colleagues, making the day-to-day work enjoyable. The company also encourages learning and development.
Cons: While the projects are interesting, the compensation package, especially for mid-level roles, doesn't always feel aligned with industry standards in Paris. Sometimes, project timelines can be demanding, leading to occasional crunch times. More clarity and consistency in career progression paths would also be beneficial for long-term planning.
Advice to Management: Consider reviewing compensation benchmarks more frequently to ensure competitive salaries. Also, clearer communication on long-term career trajectories would be greatly appreciated by employees.

Good engineering firm with international reach
Pros: Deerns offers exposure to large-scale, technically demanding projects, which is great for professional development in the building services sector. The company culture fosters collaboration across different disciplines and locations. There's a genuine commitment to sustainability and innovation, which is motivating. The Milan office team is quite close-knit and supportive, making day-to-day work enjoyable.
Cons: While leadership is generally experienced, communication from the top on strategic decisions can sometimes be less frequent than desired. Career progression pathways, while present, could be more clearly defined for specific roles. Sometimes project demands can lead to periods of intense workload, impacting work-life balance slightly.
Advice to Management: Enhance visibility of strategic company direction and clarify internal career progression frameworks further. Recognize and reward strong project performance consistently across teams.
