You’ll make a difference by:

 • Coordinating cross-functional inputs – Working closely with sales, engineering, finance, legal, and customer service to gather scope, pricing, technical, and commercial inputs for brownfield service and upgrade opportunities.
 • Managing commercial costing and approvals – Building and validating pricing models, coordinating supplier quotes, and ensuring timely internal approvals prior to customer submission.
 • Creating compelling proposal content – Writing clear executive summaries, value propositions, and customer-specific narratives that clearly articulate the value of enhancing, maintaining, or extending existing systems.
 • Ensuring proposal quality and compliance – Reviewing proposals for accuracy, completeness, brand alignment, and adherence to internal processes, commercial standards, and security requirements.
 • Improving proposal effectiveness and win rates – Using bid outcomes and customer feedback to refine messaging, scope language, and proposal turnaround efficiency for lifecycle and installed-base opportunities.

Your defining qualities:
 • Proven proposal or bid management experience – 5–7 years of experience in proposal management, bid coordination, or sales support within a technical or services environment.
 • Strong commercial and financial understanding – Comfortable managing pricing, costing models, and commercial terms with attention to accuracy and risk.
 • Experience with brownfield or installed-base projects – Familiarity working with existing systems, legacy environments, or live customer sites, ideally within building or industrial technologies.
 • Clear and persuasive communicator – Able to translate technical assessments and commercial inputs into concise, customer-ready proposals.
