Are you a STEM contractor who prefers Outside IR35 assignments and regulated, technically interesting projects?
I’m building a new interim & contract network at Cranleigh STEM for future projects across:
Quality & Compliance
QA / Quality Consultants
Validation & CSV
Quality Systems & Supplier Quality
GxP / GMP / Regulatory support
Engineering & Manufacturing
Manufacturing & Process Engineers
Bioprocess / Scale-up Engineers
Technical & Capital Projects Engineers
Operations & Production leadership (interim)
Delivery & Transformation
Technical Project / Programme Managers
Operational & site transformation specialists
This is for future contract opportunities that are:
Structured with Outside IR35 in mind
Focused on regulated and technical environments
Project-led rather than backfill-heavy
Locations we actively cover:
London & South East
London, Reading, Slough, Maidenhead, Stevenage
Northern England
Manchester, Liverpool, Leeds, Sheffield, Newcastle upon Tyne, York
Scotland
Edinburgh, Glasgow, Dundee, Aberdeen
Why register?
I work with science, engineering and manufacturing organisations that:
Use specialist contractors
Need people who can deliver in regulated environments
And are rethinking how they engage contractors ahead of the April changes
Registering simply means:
· You’re on my radar when suitable Outside IR35-led opportunities come up
· You’re contacted before roles are pushed widely to the market
Interested?
