Systems Engineer contracting in the UK

Systems Engineer contracts on this page come straight from the live ContractorUK jobs board — systems and integration engineering across defence, rail and tech. Advertised day rates vary widely with sector, location, clearance and specialism, so treat any single figure with care — every card above shows the advertised rate and the recruiter-stated IR35 status side by side. Before you negotiate, run the actual rate through our contractor calculators to see the take-home difference inside versus outside, and if the rules are new to you start with what IR35 is and how it works.
