Actemium Design, part of VINCI Energies, is inviting applications from experienced, innovative Process Engineers for exciting opportunities at Senior and Principal Engineer levels. If you are passionate about process engineering and driven to deliver excellence within regulated sectors, we want to hear from you.

Senior / Principal Process Engineer

Join our renowned Process Engineering team and work at the forefront of engineering design and project delivery for the UK’s most vital industries, including nuclear, energy, chemical processing, and heavy industry. Our projects span early conceptual development through to detailed engineering, offering you the opportunity to influence key decisions and deliver tangible impact. We’re committed to supporting the growth and development of talented Process Engineers looking to make a difference and shape modern industry.

Main Responsibilities

Lead or support the delivery of high-value process engineering design solutions, including process flow diagrams (PFDs), piping & instrumentation diagrams (P&IDs), heat and mass balances, process calculations, and technical specifications.
Collaborate with multidisciplinary teams—mechanical, EC&I, SHEQ, and project management—to ensure fully integrated and compliant solutions for clients.
Apply expert knowledge of process engineering principles, process systems, and regulatory requirements to design robust, safe and cost-effective processes.
Undertake rigorous technical calculations, modelling and simulations to verify performance and ensure regulatory, client, and stakeholder requirements are met.
Actively participate in HAZOPs, LOPA studies, safety and constructability reviews, and other risk management activities.
Mentor and develop less experienced engineers, supporting a collaborative, knowledgeable and high-performing team environment.
Prepare, review and update technical documentation, proposals, procurement specifications and client reports.

Essential Skills & Experience

Degree-level qualification (or equivalent relevant experience) in chemical engineering, process engineering or a related discipline.
Substantial experience in process design and engineering delivery, ideally within regulated industries (nuclear, chemical, energy, oil & gas, or heavy/process industry).
Proficient in process engineering software and tools (e.g. Aspen HYSYS, AutoCAD, process simulation packages).
Strong understanding of UK and international process engineering standards, legislation, and best practice.
Proven ability to produce, check and validate process design deliverables including PFDs, P&IDs, datasheets and calculations.
Strong communication skills, with the ability to explain technical concepts clearly to colleagues, clients, and stakeholders from varied backgrounds.
Organised and analytical, with a focus on quality, risk management and continuous improvement.
Willingness and ability to travel to client and project sites as required.

What We Offer Process Engineers at Actemium Design

Competitive salary, enhanced pension contributions, annual bonus, and comprehensive Health Shield plan.
Outstanding benefits, including 26 days holiday (plus bank holidays), EV car scheme, company share scheme (subject to qualifying periods), and death in service insurance.
Hybrid and flexible working options to support your work-life balance and enhance productivity.
Bespoke progression and career development opportunities with support from industry leaders (VINCI Energies).
An inclusive, supportive, and knowledgeable team environment where your growth and contributions are valued.
