Case Studies: Our Proven Success in High-Stakes Engineering Recruitment for Manufacturing
We provide effective technical staffing solutions for London’s manufacturers and across the UK. Explore our case studies below to see how we solve complex recruitment challenges.
Case Study: Sourcing a Niche Electronics Design Engineer
The Challenge: A global high-tech manufacturing client needed to hire a specialist Electronics Design Engineer in a highly competitive local market. The talent pool was extremely limited, and they were competing against companies offering higher salaries and better benefits.
Our Solution: We conducted a deep vacancy analysis with the HR and line manager to define essential criteria. A detailed market map and sourcing plan were created to identify and engage passive candidates across multiple platforms, including a targeted PPC campaign to a custom audience with an interest in electronics.
The Result: We successfully presented three highly-skilled, fully-vetted candidates. The client proceeded with two to the final stage and hired an exceptional engineer who has since completed over two years of successful service. This demonstrated our ability to deliver in even the most challenging talent markets.
Case Study: High-Volume Maintenance Team Expansion
The Challenge: A global chemical company was undertaking a major site expansion and needed to hire 15+ maintenance staff with varied skillsets (mechanical, electrical, automation). The roles had complex shift patterns and a salary structure that made them difficult to fill in a candidate-driven market.
Our Solution: We worked as a strategic partner, creating SEO-optimised adverts for each skillset and launching a high-volume sourcing plan. We managed the entire process, from thoroughly screening candidates on the complex package to briefing them for the client’s extensive 4-hour interview process, booking 14 interviews in a single week.
The Result: During the project, Sigma successfully placed 15 maintenance staff. Our rigorous pre-screening and management of the complex onboarding process ensured a high conversion rate from interview to hire, enabling the client to meet their critical expansion deadlines.
Why the Best London Engineering Recruitment Agencies are Partners, Not Suppliers
The difference between a transactional recruiter and a true recruitment partner can have a significant impact on your hiring success, company culture, and long-term growth. Here’s how they compare.
| Aspect | The Transactional Agency | ✅ The Recruitment Partner (Sigma) |
|---|---|---|
| Primary Goal | Fill the role as quickly as possible to earn a fee. | Find the right long-term candidate who aligns with your technical needs and company culture. |
| Process | Forwards a high volume of unvetted or poorly-vetted CVs from a single source. | Consults on the role, conducts in-depth screening interviews, and only presents a qualified shortlist. |
| Communication | Infrequent or purely reactive updates. You often have to chase them for information. | Proactive communication, providing market insights, feedback, and regular progress reports. |
| Market Knowledge | Generalist understanding of many industries. | Deep, specialist knowledge of the engineering and manufacturing sectors. |
| Outcome | A placement that may or may not last. The relationship ends when the invoice is paid. | A valuable new team member. The relationship continues to ensure a smooth onboarding and future success. |
