AI/ML ENGINEER

Founded in 1990 as a provider of integrated modelling software for the oil and gas industry, our organisation has grown into a highly successful enterprise. We now serve over 450 clients worldwide, ranging from universities to major multinational corporations. In our most recent fiscal year, the company achieved a turnover of £66 million and has accumulated significant cash reserves earmarked for future expansion.

In this regard, we see an exciting future which embraces the challenges around energy transition technologies and renewables. In addition, we see huge scope in applying the lessons that we have learnt within this industry to other sectors, notably mining, banking, power, water and healthcare.

With this in mind, the company is on the cusp of a major expansion. Part of this involves the relocation of the headquarters from Edinburgh to Guildford in Surrey, to take advantage of the improved travel links, recruitment possibilities, and links to London. An office has been purchased and the newly refitted office opened in October 2024. The Guildford office will become the company headquarters in September 2025.

PE Limited currently has 110 staff, split roughly between technical support, product development and contract and licensing administration. The technical staff are all highly qualified, with almost everyone having at least a Masters qualification and many holding PhDs.
