Why Hiring Specialist Engineers Is Becoming More Difficult

A vacancy for an Electronics Design Engineer can attract plenty of applications and still leave an employer struggling to make a hire. This reflects a wider challenge facing specialist engineering recruitment across the UK. Many employers recruiting Electronics Engineers, Embedded Software Engineers, Control Systems Engineers, Automation Engineers and other highly skilled technical professionals are discovering that candidate availability does not always translate into hiring success.

The shortlist becomes much smaller when the project needs someone who can take responsibility for power supply design, take a product through verification and support its introduction into production. Add regular laboratory work at a particular site, and the pool shrinks again.

This example helps explain why greater candidate availability does not necessarily make specialist engineering recruitment easier. Employers increasingly need particular combinations of technical knowledge and practical experience, while those skills can take years to develop.

Technology is changing those requirements too. Automation, embedded systems, artificial intelligence (AI), electrification, digitalisation and Industry 4.0 are creating new engineering challenges and increasing the overlap between disciplines.

For employers, understanding what’s narrowing the available talent pool is the starting point for a more effective search.

Why is hiring specialist engineers becoming more difficult?

Hiring specialist engineers is becoming more difficult because employers increasingly require niche combinations of technical expertise, sector knowledge and practical engineering experience. While candidate availability has improved in some areas of the UK engineering jobs market, businesses continue to face engineering skills shortages across disciplines including electronics design, embedded software, automation, control systems, AI, machine learning and power electronics.

Engineering roles are becoming more specialised as skills shortages grow

The IET’s 2025 UK Engineering and Technology Skills Survey found that 76% of engineering employers struggled to find certain skills when recruiting.

The skill shortages are spread across multiple areas. Employers identified gaps in technical engineering, specialist digital and sustainability skills, while capabilities including innovative thinking and solving complex problems are expected to become increasingly important for future growth.

Our September 2026 engineering and technology labour market insights show a similar picture. Candidate availability has improved, but businesses continue to compete for specialist expertise across sectors ranging from electrical engineering to AI and machine learning.

Part of the challenge is that job titles only tell you so much. Two Electronics Engineers may use the same design tools but have very different experience of power architectures, EMC compliance, verification testing or production support. Two Controls Engineers may both programme PLCs but have worked on very different automation systems and industrial environments.

As projects become more specialised, employers are increasingly recruiting for combinations of experience rather than a job title alone. This is one reason why engineering recruitment remains challenging despite wider improvements in candidate availability.

New technologies are reshaping engineering skills requirements

Engineering technology can develop much faster than the supply of experienced people who know how to apply it effectively.

Automation is one example. Businesses investing in robotics and connected equipment need engineers who understand how sensors, controllers, software and wider systems interact. This is contributing to demand across areas such as process control and automation, robotics, systems integration and industrial digital transformation.

Products are also combining more electronics, software and connectivity. This is creating demand for engineers who understand multiple stages of the product lifecycle or who can work effectively alongside specialists in areas such as embedded software, firmware development and cyber security.

AI is another emerging example. Adoption across engineering and manufacturing is still developing, but businesses looking to introduce it can face a shortage of people with the skills needed to turn the technology into practical applications. The IET found that 58% of engineering employers were using AI in some form, although only 18% used it regularly.

The wider challenge is the same. Businesses often need expertise in a technology before a large talent pool has had time to develop substantial commercial experience using it.

Customer and project requirements are adding complexity

Technology is not the only factor changing engineering roles.

Customers increasingly expect greater integration between products and systems, while businesses face evolving requirements around cyber security, sustainability, energy efficiency, product compliance and regulation.

That can add new layers to an existing role.

A product that previously operated independently may now need connectivity. Equipment may need to integrate with a customer's existing control architecture. A design entering a different market may require additional testing, verification or compliance work.

These changes do not necessarily create entirely new engineering professions. More often, they increase the combination of knowledge required within existing teams.

An employer may therefore find plenty of Electronics Engineers in the market, but far fewer who understand the particular technology, application, regulatory environment and stage of development involved in their project.

Why experienced engineering talent remains in short supply

There is another important constraint: experienced engineers cannot be created overnight.

Specialist knowledge is often built through years of designing products, testing systems, investigating failures, commissioning equipment and supporting products once they reach production.

New technology can be taught, but practical engineering judgement takes significantly longer to develop.

This is particularly important when experienced engineers leave the workforce. The IET found that only 57% of employers considered themselves effective at transferring knowledge from retiring employees, highlighting the risk of valuable technical expertise being lost.

This highlights the importance of engineering workforce planning, succession planning and skills development strategies. Businesses that invest in graduate recruitment, professional development and knowledge transfer programmes are often better positioned to address long-term engineering skills gaps and protect critical technical capability.

Project requirements can narrow the engineering talent pool further

Even when the required expertise exists in the market, the practical requirements of the role can reduce the number of suitable candidates.

A business recruiting well ahead of a programme may be able to appoint someone who can develop into the role. A team facing a stalled design or approaching customer milestone may need someone who can take technical responsibility much sooner.

Location can have a similar effect. Laboratory testing, manufacturing support and commissioning may require access to specialist facilities, making fully remote working impractical for some engineering roles.

Sector requirements also need careful consideration. Previous experience in a particular industry can be essential where specific standards or operating environments are involved. In other cases, an engineer from another sector may have directly transferable experience of the technical problem.

The recruitment brief should therefore distinguish between what is genuinely essential and what can be learned. Every additional requirement reduces an already specialist candidate pool.

Where expertise is needed immediately for a defined piece of work, contract and interim engineering support can also provide another way to access specialist skills.

Competition for specialist engineers remains strong

While more candidates may be looking for work overall, that does not remove competition for engineers with scarce technical expertise.

Our engineering recruitment market insights show continued salary pressure within specialist roles, with employers that move quickly and offer competitive packages better placed to secure sought-after engineers.

The opportunity also needs to give candidates enough information to make a decision. An experienced engineer may want to understand the stage of development, available facilities, technical responsibilities and balance between new development and existing product support.

Salary expectations should reflect the expertise being requested. Combining multiple hard-to-find skills without reviewing the compensation package can create a vacancy that is technically possible to fill but difficult to recruit for in practice.

Once a suitable candidate has been identified, the hiring process should provide a clear route to a decision. Lengthy interview processes, uncertain approval timelines and delayed feedback can increase the likelihood of losing high-calibre engineering candidates to competing employers.

What should employers do when a specialist engineering vacancy stays open?

When specialist engineering recruitment proves challenging, the first step is to assess what the search is telling you.

If candidates repeatedly lack one specific skill, consider whether it genuinely needs to be present from day one or whether it could be developed through training and support. If suitable candidates consistently struggle with the location requirement, evaluate how much on-site attendance is actually necessary.

Look carefully at rejected candidates too. Recurring patterns may reveal that transferable skills are being overlooked, the candidate criteria are overly restrictive or the role combines too many specialist requirements.

Employers struggling to hire specialist engineers should also consider:

• Reviewing which requirements are essential and which are desirable.
• Benchmarking salaries against the current engineering recruitment market.
• Expanding geographical search areas where possible.
• Exploring candidates with transferable sector experience.
• Investing in internal skills development and succession planning.
• Using contract or interim engineering professionals to support immediate project demands.

Where expertise is genuinely scarce, the answer may be to widen the search, adjust the package, build talent internally or engage specialist contractors while a permanent solution is found.

A specialist recruitment partner can help identify where candidates match, where the market differs from the original brief and what is preventing the search from progressing.
