About Our Inside IR35 Automation Engineer Contract Roles
What does a automation engineer contractor do?
Automation Engineer contractors are engaged to design, build, and maintain automated systems that improve the efficiency, reliability, and scalability of engineering, manufacturing, and software delivery processes. The term covers two distinct but related domains: industrial automation, which involves the design and implementation of automated machinery, control systems, and robotics within manufacturing and process environments, and software test or process automation, which involves building automated testing frameworks and DevOps pipelines within technology delivery programmes. Contractors are typically brought in for defined automation projects, system upgrades, or to provide specialist expertise that a permanent team does not hold.
Technical skills expected vary significantly by domain. Industrial Automation Engineers need expertise in PLC programming, SCADA systems, robotics integration, and the relevant safety standards for automated machinery, with proficiency in platforms from vendors such as Siemens, Rockwell, or Mitsubishi depending on the client environment. Software and test automation contractors need strong programming skills, typically in Python, Java, or JavaScript, alongside experience with testing frameworks such as Selenium, Playwright, or Cypress, and familiarity with CI/CD tooling. Across both domains, the ability to design automation solutions that are maintainable, well-documented, and capable of being handed over cleanly to permanent teams is consistently valued.
What is the market like for automation engineer contractors?
Automation Engineering contracting is active across both its main domains. Industrial automation demand is being driven by manufacturing investment in productivity improvement, reshoring initiatives, and Industry 4.0 adoption, with particular activity in automotive, food and beverage, pharmaceuticals, and utilities. Software and test automation demand remains strong within technology and financial services organisations running large agile delivery programmes that require scalable test coverage. Contractors who span both programming ability and process knowledge are in the strongest demand across both segments, as the boundaries between industrial and software automation continue to converge.
What does Inside IR35 mean?
IR35 is UK tax legislation that determines whether a contractor is genuinely self-employed or working in a manner that resembles employment. When a contract is classified as inside IR35, income tax and National Insurance are deducted at source, typically via an umbrella company or agency PAYE. Headline day rates on inside IR35 engagements are generally higher than equivalent outside IR35 roles to account for the tax and employment cost structure.
Inside IR35 determinations are made where the working arrangements are considered to resemble employment, based on factors including the level of client control, the absence of a genuine right of substitution, and the presence of mutuality of obligation. Since April 2021, the end client is responsible for making this determination for medium and large private sector organisations. Many employers in financial services, government, and professional services assess the majority of their contractor engagements as inside IR35.
On QualityContracts.co.uk, approximately 49% of roles with a stated IR35 status are classified as inside IR35, making it the most common arrangement across the contract market. The proportion varies by sector and role type. Each listing on this page displays its IR35 status where provided by the hiring organisation.
What automation engineer roles are usually Inside IR35?
Financial services and large technology organisations account for most inside IR35 automation engineering work, at around 55% of contracts where status is stated. Inside IR35 automation work tends to be more operational that maintain in-house automation teams. Inside IR35 automation work tends to be more operational: maintaining and extending existing test frameworks, running regression suites, and integrating automation into CI/CD pipelines as part of an established delivery team. The breadth of the automation engineering discipline, spanning test automation, RPA, and infrastructure automation, means IR35 treatment varies significantly by the type of engagement.
How much do automation engineer contractors usually earn when working Inside IR35?
Contract rates for automation engineer roles typically range from £400 to £750 per day, depending on the scope of the role, required expertise, and the delivery expectations of the engagement. Inside IR35 rates are typically 15% to 30% higher than equivalent outside IR35 roles to account for tax and national insurance deducted at source by the fee-payer.
