Recruitment Case Studies - UK Engineering

Heavy Industrial Recruitment

The client required maintenance technicians and engineers but struggled to attract candidates due to a weak reputation, which also drove higher turnover. Salaries were below the market rate. Sigma partnered with HR to benchmark pay and tackle reputation challenges. We surveyed candidates, built a microsite, and re-engaged those who had previously declined.

Food Manufacturing Recruitment

Sigma Recruitment has developed a substantial internal database over 14 years, using “rearview mirror talent sourcing” to identify candidates who previously worked as product development technologists. Our research showed that NPD technologists were typically food science or technology graduates, and we targeted recent grads through a range of marketing campaigns.

Electronics Manufacturing Recruitment

The client faced several challenges, including a limited talent pool for electronics engineers, competition from higher-paying roles, and a niche market. Sigma carried out research, ran ads across job sites and social media, and developed a targeted PPC campaign and sourcing strategy to attract the right candidates.

Automotive Recruitment Agency

Recruiting automotive talent for a company facing retention and staffing challenges required a focused approach. Sigma Recruitment leveraged its network, industry expertise, and in-depth research to successfully hire 35+ skilled staff within one year.

Aerospace Recruitment Agency

A leading aerospace supplier required a Mechanical Design Engineer but faced strong counter-offers and an internal HR gap. Sigma managed the process and used a text-mailer campaign to identify and assess five qualified candidates.

Medical Device Recruitment Agency

Sigma Recruitment supported a growing medical device client under an exclusive agreement, hiring from graduate to director level. Despite low salaries and limited talent, we requalified the brief, widened the search, and adjusted pay—delivering 8 candidates and securing a successful director hire.

FAQ’s

Quick answers to common questions about our UK manufacturing recruitment agency. Learn how we fill permanent and contract roles, our average time-to-hire, why we’re different from generalist recruiters, and how we support manufacturers of all sizes nationwide.

How quickly can you fill manufacturing roles?

  • It depends on complexity, but generally time-to-offer is around 30-40 days or less, thanks to a large network of engineering professionals.

Do you work with SMEs as well as large manufacturers?

  • Absolutely. From single-site food producers to multinational OEMs, we tailor our recruitment approach to your size and structure. Current clients vary in headcount from 6 to thousands.

Where are you based?

  • Our head office is in Cardiff, and our team supports employers nationwide across England, Scotland, and Wales.

How is AI changing manufacturing recruitment in 2025 and 2026?

AI is shifting the focus from simple manual labour to data literacy. We are seeing a significant surge in demand for “human-in-the-loop” roles in which technicians must manage automated systems. Recruitment now prioritises candidates who can bridge the gap between traditional engineering and digital oversight.

What are the most in-demand Industry 4.0 skills for UK engineers?

The top skills currently include predictive maintenance, industrial IoT integration, and collaborative robotics (Cobots). Employers are no longer just looking for mechanical proficiency. They need “multi-skilled” engineers who understand how software and hardware interact in modern production lines.

How does the transition to Green Manufacturing affect the talent pool?

The move toward Net Zero is creating a “green skills gap” in the UK. Manufacturers are competing for specialists in waste reduction, energy-efficient processing, and sustainable supply chain management. We help clients identify transferable skills from traditional sectors to fill these new environmental roles.

What is the hidden cost of a manufacturing vacancy staying open?

Beyond missed targets, a long-term vacancy can cause “overtime fatigue” among your remaining team. This often leads to a drop in Overall Equipment Effectiveness (OEE) and increased health and safety risks. Our goal is to reduce your time-to-hire.

How can manufacturers compete for talent against larger OEMs?

SMEs can win top talent by offering “pathway clarity” and agility. While major manufacturers offer high salaries, smaller firms often provide more varied roles and quicker career progression. We help SMEs highlight their unique culture and flexible working patterns to attract high-tier engineers.

What is the difference between active and passive candidates?

Active candidates are currently browsing job boards, whereas passive candidates are high-performers currently in a role.Most of the top 10% of manufacturing talent is passive. We use our 20-year network to headhunt these individuals who are not looking at traditional adverts.

How do you benchmark manufacturing salaries in different UK regions?

Salaries vary significantly across hubs such as South Wales, the Midlands, and the North of England. We provide real-time benchmarking based on current placements and market intelligence. This ensures your offer is competitive enough to prevent rivals from issuing counteroffers.
