ABOUT OUR OPPORTUNITY

Our Summer Internships are based at one of Scotland’s largest manufacturing sites – with a business that has already made a commitment and is actively working to reduce greenhouse gas emissions from its operations in Grangemouth by more than 60% by 2030.

Successful candidates will be contributing from Day 1, working on real projects and gaining invaluable work experience to add to your CV and give you practical examples to draw upon for your final year at University.

An internship with INEOS Grangemouth offers first hand exposure to the manufacturing industry and knowledge on the processes involved. Our summer interns get to see how the engineering concepts and principles taught in university are applied to real projects.

You’ll be embedded into one of our experienced teams, mentored and developed, learning all about our culture and business as well as about your engineering discipline. And in return, while you’re with us, we’ll be getting to know you. So when the time comes to apply for a Graduate position, if you choose INEOS, we’ll know each other a little better.

Our internships will take place over a 12-week period during summer 2026, so if this opportunity excites you please see the under-graduate requirements below.

Please note we may close applications early if we receive a high volume of interest.

About the company

Ineos

Company overview
INEOS is a global petrochemicals manufacturer operating across a wide set of chemical and energy-related businesses, alongside newer activities such as automotive (INEOS Grenadier). The company runs large-scale manufacturing and logistics operations that supply industrial customers worldwide, with separate business units that hire and operate with significant independence. INEOS also publishes sustainability reporting that includes workforce and contract mix data.

Locations and presence

INEOS reports operating 154 sites across 27 countries, so most roles are tied to specific plants, offices, and regional business units rather than a single global campus. Early-career roles are typically site-based (especially engineering and operations), with some corporate HQ activity depending on the programme and function.

Palpable Score

71
/ 100
INEOS offers credible early-career access through structured graduate programmes plus apprenticeships and internships, with clear programme descriptions and a defined selection process for at least the core commercial track. Pay transparency is the main weak spot because publicly listed salary ranges are inconsistent across early-career pages, and the company does not publish conversion or promotion metrics. Recent public reporting about hiring constraints and job cuts in parts of the wider INEOS group adds uncertainty for candidates trying to plan a “safe” first role, depending on the business unit.
