• Review tender documentation to understand client requirements, specifications, pricing templates, and evaluation criteria.
• Collaborate with operational managers, regional leads, and the control room team to gather and structure technical content.
• Develop win themes, solutions, and differentiators aligned to Land Sheriffs’ operational strengths and innovation.
• Coordinate bid schedules, ensuring the timely delivery of all submissions, supporting documents, and clarifications.
• Produce case studies, CVs, risk assessments, mobilisation plans, and method statements tailored to each tender.
• Work with finance and leadership teams to support pricing exercises and commercial strategy.
• Maintain and enhance the company’s bid library, templates, and best-practice documentation.
• Prepare presentation material for post-tender clarification meetings and client interviews.

• Proven experience as a Bid Manager, Bid Writer, Proposal Manager, or Commercial Manager within security, FM, rail, or safety-critical services.
• Strong understanding of security service delivery models (e.g., manned guarding, patrols, rapid response, control room operations).
• Excellent written English with the ability to turn technical information into persuasive, client-focused content.
• Highly organised and able to manage multiple bids concurrently under tight deadlines.
• Strong communication and stakeholder engagement skills.
• Ability to work independently while remaining collaborative with operational teams.
• High level of IT competency (Word, Excel, SharePoint, document management).
• Understanding of public sector procurement processes (e.g., rail, local authority, utilities) is advantageous.

• Competitive salary (up to senior-level depending on experience)
• Hybrid working model – flexibility to work from home 4 days weekly
• Opportunity to shape major UK-wide bids in a respected, growing organisation
• Supportive and collaborative leadership team
• Career development and training opportunities
• 25 days holiday + bank holidays
