Why some roles remain hard to fill, even when the job market feels tougher
On paper, the UK job market looks more challenging for job seekers than it did during the post-pandemic hiring boom. Vacancies have fallen, employers are being more cautious, and candidates are often finding that roles attract higher volumes of applications. The ONS reported that UK vacancies fell to 712,000 in April to June 2026, with 2.5 unemployed people per vacancy in March to May 2026.
For manufacturing employers, however, this does not mean that every role has suddenly become easy to fill. In fact, many critical technical and engineering positions remain stubbornly difficult. Particularly across science, engineering and manufacturing businesses in the South and South East of the UK.
This is the gap between the headline labour market and the specialist STEM labour market. There may be more people actively looking for work, but that does not mean there are more people with the right combination of technical knowledge, hands-on manufacturing experience, problem-solving ability and sector knowledge.
Manufacturing recruitment is not just about finding a volume of applicants
One of the most common misconceptions in recruitment is that a tougher job market automatically gives employers access to more candidates. For some generalist roles, that may be true. But for specialist manufacturing positions, the challenge is rarely a lack of CVs. It is a lack of relevant, available and suitable people.
Manufacturing businesses often need candidates who can do more than perform a defined task. They need people who understand production processes, quality requirements, continuous improvement, safety standards, equipment limitations, materials, documentation and customer deadlines. These skills are usually built through years of practical experience, not picked up quickly through short-term training.
This is why roles such as a Production Engineer can remain difficult to recruit for, even when the wider market appears to favour employers. A good Production Engineer may need experience with process improvement, Lean manufacturing, tooling, NPI, production support, root cause analysis and cross-functional work with design, quality and operations teams. That blend of skills is valuable, but it is also rare in the local South and South East Job Market.

Why critical manufacturing roles are so difficult to fill
There are several reasons why manufacturing businesses continue to face recruitment challenges.
The skills gap is still very real
The UK engineering and manufacturing skills shortage has not disappeared. Research from Barclays and The Manufacturer found that 75% of manufacturers identified skills shortages as their biggest barrier to growth, while recruitment challenges and talent retention were also major concerns.
The Institution of Engineering and Technology also reported that 76% of engineering employers struggle to recruit for key roles, with technical and specialist skills among the main pressure points.
For employers, this means there is often a mismatch between the people available in the market and the skills required to keep production running, improve efficiency or support growth.
Experienced engineers are in short supply
Many manufacturing businesses need people who can make an impact quickly. That often means hiring experienced engineers, managers, technicians or specialists who have already worked in similar environments.
The difficulty is that experienced candidates are often already employed. They may not be actively applying for roles, and they may need a compelling reason to move. Salary matters, but so do commute, flexibility, career progression, company stability, technology, management culture and the perceived quality of the working environment.
This is particularly relevant in the South and South East, where SME employers may be competing not only with other local manufacturers, but also with Blue-Chip aerospace, defence, electronics, medical technology, scientific instrumentation, energy, automotive supply chain and advanced engineering businesses.
Manufacturing roles are becoming more complex
Modern manufacturing is increasingly technical. Automation, digital systems, data, sustainability, quality standards and process optimisation are changing what employers need from their people.
The result is that many roles now require a broader skill set than they did ten years ago. A manufacturing business may no longer need someone who can simply “keep production moving”. It may need someone who can identify inefficiencies, support automation projects, analyse recurring defects, work with suppliers, improve yield and contribute to long-term operational improvements.
That raises the bar for recruitment.
Location still matters
Manufacturing recruitment is often more location-sensitive than office-based hiring. Many production, engineering and operations roles need to be site-based. That means the realistic candidate pool is limited by commuting distance.
In the South and South East, this can be a major factor. A strong candidate may be technically suitable, but if the journey is too long or the role requires a daily commute across congested routes, they may not engage. This is one reason why specialist local knowledge matters when recruiting for engineering and manufacturing roles.
Candidates are more selective than employers expect
Even in a tougher market, good candidates still have choices. Skilled engineers, production specialists and technical managers are often cautious about moving unless the opportunity is clearly better than their current role.
Candidates may ask:
Is the salary genuinely competitive?
Is the company investing in equipment, people and processes?
Is there a clear reason for the vacancy?
Will the role offer progression?
Is the management team stable?
Does the business have realistic expectations?
Will the commute work long term?
If employers cannot answer these questions confidently, they may struggle to secure the candidates they want.
What manufacturing businesses can do differently when recruiting
Recruiting critical manufacturing roles requires more than advertising a vacancy and waiting for the right person to apply.
Employers can improve results by:
- Defining what is essential and what can be trained
- Moving quickly when strong candidates are identified
- Benchmarking salary and benefits against the real local market
- Being clear about progression, training and investment
- Selling the opportunity, not just listing responsibilities
- Considering adjacent sector experience
- Working with a specialist recruiter such as Senex Recruitment who understands the technical requirements and the local candidate market
For example, when recruiting a Production Engineer, it may be tempting to search only for candidates who have held the exact same job title in the same industry. But some of the strongest candidates may come from related manufacturing environments where they have solved similar production, process or quality problems. A recruiter can help you find these people through industry knowledge and personal experience, the human touch is still vital even in today's automated environment.
The headline job market does not tell the whole story
The wider labour market may be more difficult for job seekers than it was a few years ago, but specialist manufacturing recruitment remains challenging. The issue is not simply whether people are looking for work. The issue is whether the right people exist in the right location, with the right skills, at the right salary level, and whether they are ready to move.
For manufacturing businesses in the South and South East, critical roles can still take time, insight and search and selection techniques to fill.
