Job Role: Technical Services Manager
Location: DSTL, Salisbury – On-site role
Salary: Up to £50,500 + Company Van
Contract: Full time, Permanent

Mainstay Recruitment are seeking a driven and passionate Technical Services Manager to support a high-security site at DSTL, Porton Down for our prestigious client. If you thrive in a fast-paced environment, enjoy solving complex technical challenges, and want to contribute to work that truly matters, this could be your next move.

The Role

As Technical Services Manager, you’ll be the engine that keeps essential systems running smoothly. You’ll lead a skilled team of engineers and operatives, ensuring planned and reactive maintenance is delivered to the highest standards. You’ll play a vital role in maintaining compliance, meeting KPIs, and supporting the safety and security of a site that plays a critical role in national defence and innovation.

Your leadership will empower others not only through operational management, but also by nurturing talent, mentoring apprentices, and developing future successors. You’ll bring out the best in your team and help create a positive, high-performance culture where people are valued and encouraged to grow.

You’ll act as the technical focal point for the site — advising the client, managing remedial works, reviewing inspection reports, and ensuring all health and safety documentation is robust and compliant. You’ll take ownership of billable works up to £25k, oversee CAFM maintenance scheduling, and ensure asset updates are accurately recorded.

This is a hands-on, customer-focused role where you’ll build strong relationships with DSTL stakeholders, colleagues, and trusted supply chain partners.

What sets this opportunity apart is the scale and impact of your work. From ensuring safety-critical assets function flawlessly to leading on statutory compliance, your expertise will directly contribute to the success of a vital MOD facility. You’ll also play a role in succession planning and long-term team development — championing diversity, encouraging learning opportunities, and helping shape the future workforce.

What You’ll Bring

You don’t need to tick every box. If you have a technical HVAC qualification (heating, ventilation, or air conditioning), are confident managing contractors and compliance, and are eager to develop, we’d like to hear from you. 

You’ll be reliable, self-motivated, and an effective communicator. Holding or working towards SMSTS and SC Clearance would be advantageous, and experience within an MOD environment would be beneficial.

It is essential that you are computer literate, comfortable working with data and different CAFM systems, and prepared for an administration-heavy, office-based role.

Please note: due to the vetting requirements of this site, applications can only be considered from British Nationals.

What We Offer

• 6% employee matched pension contribution
• 25 days annual leave
• Use of company van
• Single private medical cover
• Life assurance (2x annual salary)
