• Generate RFIs, detailed bills of materials (BOMs), and labour cost estimates.
• Develop comprehensive and accurate project cost models to support final bid.
• Ensure all solutions and costings fully comply with client specifications, standards, and commercial requirements.
• Engage directly with clients to present solutions, support technical discussions, and promote Circet’s capabilities.
• Attend client meetings and support post‑tender clarification and negotiation stages.
• Ensure all RFQ and bid deadlines are met in a structured and controlled manner.
• Liaise closely with Operations, Sales, Commercial, Finance, and Health & Safety teams to ensure bid alignment and deliverability.
• Maintain strong relationships with suppliers and manufacturers to remain informed of evolving technologies, products, and best practices.

Key Requirements

• Demonstrable experience delivering pre‑sales support for high‑value, complex projects, including double‑digit multi‑million‑euro opportunities.
• Minimum of five years’ proven experience in a pre‑sales, estimating, or technical consultancy role within the industry.
• Extensive knowledge of data centre passive infrastructure systems, vendors, and supply chains.
• Strong commercial acumen with a clear understanding of cost drivers and risk management.
• Exceptional attention to detail with a structured, analytical approach to problem‑solving.
• Ability to work effectively under pressure and meet demanding deadlines.
• Self‑motivated and capable of working independently with minimal supervision.
• Proven ability to manage and prioritise multiple concurrent opportunities.
• Confident communicator with the ability to present technical and commercial proposals to clients.
• Proficient in Microsoft Office applications.
• Proficient in Google Workspace applications.
• Professional certifications such as RCDD, CNIDP, or CDCP are desirable but not essential.
