Scotland’s life sciences sector employs around 42,500 people and the chemical sciences sector around 11,000, according to figures published on Scotland.org. Both depend on engineers to design, validate and maintain regulated process plant, from chemical manufacturing and pharmaceutical production to medical device assembly. Many sites run around the clock, so reliability and maintenance engineering carry as much weight as design and project work.
Grangemouth remains Scotland’s largest industrial complex even after crude oil refining there ended in 2025, and its chemical plants still need process, instrument and maintenance engineers. Life sciences manufacturing and research are spread across West Lothian, Edinburgh, Dundee, Glasgow and the Inverness Campus, and process engineering skills are also in demand in water treatment, energy from waste, hydrogen and carbon capture.
Employers find it hardest to recruit process engineers with plant experience, validation and qualification engineers who understand GMP, instrument and control engineers, and maintenance engineers who can work within strict regulatory and safety systems.
Demand also comes from contract manufacturers and specialist equipment suppliers who serve these sites and need engineers able to work on client premises under the same rules.
Hiring in these industries usually involves more people than elsewhere, with quality, EHS and site leadership all having a say. We plan interview stages around that so strong candidates are not lost to a slow process.

Process and life sciences roles cluster around Falkirk and Grangemouth, Edinburgh and West Lothian, Dundee, and Inverness, where the Inverness Campus hosts life sciences businesses. Every area we cover is on our engineering recruitment locations page.
Process skills are shared with food and drink engineering, hydrogen and carbon capture projects sit within energy and renewables, and plant maintenance overlaps with manufacturing and industrial work.

Most engineering assignments take 4 to 6 weeks, depending on how complex the role is. Recent examples include a Maintenance Engineer placed in 3 weeks and a Quality Manager placed in 6 weeks. We give you an honest view of the likely timescale when we take the brief.
Every engineer is interviewed by phone and on a Teams video call before you see a CV. Each CV comes with a written summary of the engineer's background, why they are looking and their salary expectations, so you only see people with the right skills, experience and motivation.
We agree terms for each assignment rather than publishing a standard rate, because the right structure depends on the role and how you want to hire. Terms include a free candidate replacement guarantee. Call 01698 464 099 to discuss your vacancy.
