Business Development Manager

£65,000 basic + performance-related commission (OTE £100k+) | Renewable Energy / Solar Security | Northampton office presence

CTSG is growing, and we are looking for a commercially astute Business Development Manager to help us turn strong market demand, existing client relationships and sector credibility into structured, profitable growth.

We design and deliver specialist perimeter security solutions for large-scale solar and renewable infrastructure projects. Our work combines technical design, electronic security, project delivery and practical site experience, so we need someone who can sell properly into complex project environments – not someone who simply chases enquiries.

This is not a hard-sales or high-volume cold-calling role. Our projects are high-value, technically involved and relationship-led; we are a small but ambitious family business, with a reputation we are fiercely protective of. Sales cycles can run for months and sometimes over a year. Success depends on asking the right questions, understanding the client’s project pressures, qualifying opportunities properly and building trust with EPCs, asset owners and wider stakeholders.

The right person will share our values, and bring structure, commercial discipline and credibility. We want someone who can help shape the opportunity pipeline, protect margin, avoid poor-fit work and make sure what we sell can be delivered well by the business.

What you’ll be responsible for

• Owning the full sales lifecycle from opportunity qualification through to contract award and commercial handover.
• Developing existing strategic accounts while identifying and converting new business opportunities.
• Building and maintaining a qualified multi-million-pound pipeline across short, medium and long-term opportunities.
• Working closely with our outsourced lead generation partner, steering targeting and prioritising the right opportunities.
• Leading opportunity qualification and bid/no-bid discussions, with focus on strategic fit, margin, capability and deliverability.
• Collaborating with design, technical, operations and leadership teams to ensure opportunities are realistic, profitable and deliverable.
• Providing clear handover to the delivery team, including scope, assumptions, exclusions, risks, programme expectations and client commitments.
• Owning CRM discipline (experience of Zoho would be ideal), keeping pipeline information accurate, current and useful.
• Representing CTSG at client meetings, industry events and key relationship opportunities.

About you

You are:

• Commercially minded and able to astutely qualify opportunities.
• Curious, proactive and comfortable asking detailed questions.
• Highly organised, with thorough, consistent follow-through and attention to detail.
• Credible with senior clients, operational teams and technical stakeholders.
• Collaborative and pragmatic, with the confidence to challenge poor-fit opportunities.
• Resilient and patient enough to work with long, relationship-led sales cycles.

You’ll bring experience of

• Business development and key account management.
• Selling high-value, solution-led &/or project-led services.
• Managing long sales cycles with multiple stakeholders.
• Working with CRM systems and producing useful commercial reporting.
• Working in technical, engineering, construction, infrastructure or similarly complex environments.

Highly desirable sector experience

• Solar, BESS, renewables, infrastructure or EPC-led project environments.
• Security, perimeter protection, CCTV, electronic security, civils or electrical sectors.

Sector experience is useful, but not the only deciding factor. Transferable capability, commercial judgement and the right approach matter more.

What you’ll receive

• Performance-related commission with OTE £100k+.
• Senior management / leadership involvement, with real influence over commercial strategy and growth.
• High autonomy, visibility and direct support from the Managing Director.
• Support from an experienced leadership team and established operational capability.
• A chance to build a serious commercial function in a growing specialist business.

What this role is not

• It is not a transactional sales role.
• It is not a “win anything at any price” role.
• It is not fully remote – a significant presence within our Northampton office will be required.
• It is not about exaggerated promises or aggressive sales culture.

It is an opportunity to play a significant role in the next stage of CTSG’s growth, helping us win the right work, with the right clients, at the right margin.
