Evolution Windows is one of the UK's leading manufacturers of premium timber-alternative windows and doors, supplying a network of approximately 80 specialist installation companies across England and Wales. Renowned for outstanding product quality, technical expertise and exceptional customer service, we continue to strengthen our position as the market leader in our sector. As part of our continued growth and ambitious plans for the future, we are seeking an experienced Technical & Sales Office Manager to play a pivotal role within the business.

This is a leadership position for a commercially minded, technically capable individual who understands the fenestration industry and is passionate about operational excellence, customer experience and team development.

Why Join Evolution Windows?

This is an exciting opportunity to join a respected and growing manufacturer during a period of significant investment and expansion.

In return, you will have the opportunity to:

• Play a key leadership role within a successful and ambitious business.
• Influence the systems, processes and standards that support future growth.
• Work with a market-leading premium product offering.
• Lead and develop a talented team.
• Make a measurable impact on operational performance and customer experience.
• Become an integral part of the company's future success.

The Opportunity

Reporting into the senior leadership team, you will assume responsibility for the day-to-day management of our Sales Office, Technical Processing, Capacity Planning and Aftersales functions.

You will ensure customer enquiries are converted into accurate quotations, orders are processed efficiently and correctly, production capacity is effectively managed, and customers receive the premium service experience synonymous with the Evolution Windows brand.

This is far more than an office management role. We are looking for a confident leader with strong technical expertise who can influence performance, improve processes and help drive the next phase of our growth.

• Lead the day-to-day operation of the sales and technical office.
• Oversee all quotation and order-processing activities from enquiry through to production release.
• Ensure quotations are accurate, commercially competitive and delivered within agreed timescales.
• Verify customer orders are technically correct and fully prepared for manufacturing.
• Develop and implement systems and processes that improve efficiency, accuracy and customer experience.
• Monitor team performance and workflow to ensure service levels are consistently achieved.

Capacity Planning & Operational Coordination

• Manage production capacity planning in collaboration with the manufacturing team.
• Ensure order scheduling aligns with production capability and customer expectations.
• Proactively identify capacity constraints and implement solutions before service levels are impacted.
• Improve operational visibility and planning accuracy as the business scales.

Technical Support & Product Expertise

• Act as the technical lead for customers and internal stakeholders.
• Review specifications and identify potential technical issues before manufacture.
• Ensure products are specified, quoted and processed accurately in line with company standards.
• Provide practical solutions and technical guidance to resolve customer queries.
• Support continuous product development and the creation of technical documentation.
• Lead the aftersales function, ensuring customer issues are resolved promptly, professionally and effectively.
• Establish clear accountability and ownership for customer concerns.
• Analyse customer feedback, recurring issues and service metrics to identify improvement opportunities.
• Collaborate with production and technical teams to address root causes and reduce repeat issues.
• Deliver an exceptional customer experience throughout the entire customer journey.

Leadership & Team Development

• Lead, motivate and develop the office, processing and aftersales teams.
• Set clear objectives, KPIs and performance expectations.
• Foster a culture of accountability, continuous improvement and customer focus.
• Coach and support team members to maximise engagement and performance.
• Create a professional, positive and high-performing working environment.
• Evaluate existing processes and identify opportunities to drive operational efficiencies.
• Implement scalable systems and procedures to support future growth.
• Use performance data to identify bottlenecks and improve productivity.
• Partner with senior leadership to support strategic business objectives.

• Experience producing quotations and processing customer orders.
• Proven ability to manage workflow, production planning and delivery commitments.
• Strong customer service, communication and problem-solving skills.
• Experience leading, motivating and developing teams.
• Excellent organisational skills and attention to detail.

• Most importantly, you understand that in a premium business, outstanding customer service is not an added extra, it is fundamental to the product and the brand.
• You are not content with maintaining the status quo. You continually seek opportunities to improve processes, raise standards and deliver better outcomes for customers and colleagues alike.
