Part of the Volker Wessels UK Group, Volker Stevin is an industry-leading civil engineering business, providing complex and innovative engineering solutions across a wide range of sectors including maritime, flood risk management, defence, energy, water and regeneration. Collaborating with, and drawing on the specialist skills of the group's business units we deliver a truly integrated, multidisciplinary service. We're looking for a talented Senior Proposals Writer to join our high-performing team.

This is a role for someone who can take ownership of complex tender responses - shaping solutions, driving strategy, and writing compelling, client-focused content that helps us win major infrastructure projects across the UK. About you We're looking for a strategic, solutions-focused Senior Proposals Writer, someone who doesn't just polish words, but shapes winning responses from the ground up. You'll take full ownership of tender responses: analysing documents, understanding client drivers, and working closely with subject matter experts to co-create the solution as well as the narrative.

You'll ask the right questions, challenge assumptions, and bring clarity to complex ideas - turning them into compelling, client-focused proposals that consistently score top marks. This role is for someone who can:
Think strategically and see the bigger picture Work independently but knows when to collaborate Influence and lead others through questions and insight - not just coordination Take responsibility for content, structure and solution - not just grammar and tone Consistently produce responses that stand out - not just meet the brief We're not looking for someone who simply edits or rewrites others' work - we're looking for someone who leads the thinking, shapes the solution, and writes with purpose, clarity and impact.

What you'll do (Primary Responsibilities):
Lead the development of high-scoring, client-focused responses for supplier questionnaires and tenders relating to infrastructure projects and frameworks. Take full ownership of responses from interpreting client requirements and shaping the solution to drafting and final editing. Collaborate with technical, operational, and commercial colleagues to co-create bespoke, strategic content. Write clear, compelling, and compliant responses that demonstrate understanding, add value, and align with client drivers and win themes.

Analyse tender documents to identify key requirements, evaluation criteria, and client priorities. Facilitate response planning (e.g. storyboarding workshops) and contribute to bid strategy and win theme development. Edit and improve content for clarity, structure, consistency, and impact, ensuring each response answers the question and scores maximum marks. Support the preparation of post-tender presentations and supporting materials. Produce content to support the business development function, including case studies, capability statements, market sounding questionnaires and presentations.

Contribute to continuous improvement of bid content, templates, and knowledge libraries. Mentor and support less experienced team members where appropriate.
