🚀 Role Summary

• Lead and coordinate the technical development and execution of complex, large-scale Data Center projects from the pre-construction phase through to execution.

• Ensure technical offers are coherent, competitive, and aligned with client contractual and financial frameworks, acting as a key liaison between commercial and technical teams.

• Drive process optimization and innovative solutions to enhance project competitiveness and cost-efficiency within a multi-technical services environment.

• Manage and coordinate internal and external stakeholders, including engineering firms, subcontractors, and cross-functional internal teams, to ensure successful project delivery.

• Uphold stringent health, safety, and environmental standards throughout all project phases, integrating them into operational workflows and design considerations.

📝 Enhancement Note: While the job title is "Design Manager," the responsibilities strongly indicate a role within the pre-construction and execution phases of large industrial projects, particularly Data Centers. This aligns with responsibilities found in advanced Sales Operations, Project Management, or even specialized Revenue Operations roles that focus on the technical and financial viability of large-scale bids and projects. The emphasis on cost estimation, technical offer assembly, and client interaction positions this role as a critical bridge between sales and project delivery, requiring strong operational and analytical acumen.

📈 Primary Responsibilities

• Project Execution Oversight:

  • Guarantee the technical soundness and development of complex industrial building studies, particularly for Data Centers.
  • Direct and coordinate the refinement and development of all-trades (TCE) execution studies for major projects.
  • Integrate operational constraints, including health/safety protocols, environmental regulations, and technical risks, into study development.
  • Ensure project execution adheres to the contractual framework and the client's financial envelope.
  • Establish study production organization, validation circuits, visa piloting, interface management, and synthesis processes.

• Commercial Phase Support:

  • Serve as the primary technical point of contact for sales teams, ensuring the coherence and technical integrity of offers.
  • Lead the assembly of technical pricing and coordinate all study stakeholders.
  • Oversee and coordinate internal and external design efforts, including those by external BETs (Bureaux d'Études Techniques).
  • Propose innovative ideas and design variants to optimize project technical and economic performance.
  • Act as the key liaison between the Commercial Manager and the Technical Team.
  • Participate actively in the technical structuring of operations: programming, selection of BETs, and techno-economic strategy.
  • Support Commercial Managers in technical client explanation meetings.

• Study Management:

  • Prepare the budget and planning for study phases.

  • Conduct preliminary estimations of construction costs.

  • Coordinate techno-economic studies and manage interfaces between different disciplines and teams.

  • Ensure a seamless transfer of the project dossier to the EXECUTION (TRAVAUX) team upon contract signing.

📝 Enhancement Note: The detailed responsibilities highlight a need for robust project management, technical expertise, and strong commercial support capabilities. From an operations perspective, this role requires deep understanding of the bid-to-project handover process, cost control mechanisms, and the ability to influence technical design for commercial advantage, which are core to successful Revenue Operations and Sales Operations functions in complex project-based industries.
