Recruiter: iO Associates

Are you a CFD Engineer with a passion for innovation and high-performance engineering?

iO Associates is proud to be working with a forward-thinking engineering organisation at the cutting edge of drilling technology. As they continue to expand their specialist engineering function, we're looking for a Computational Fluid Dynamics (CFD) Engineer to join their team.

🔧 The Role

You'll join a collaborative, cross-disciplinary engineering team focused on enhancing the performance of highly specialised tools through fluid dynamics modelling and optimisation. From supporting existing product lines to helping shape the next generation of downhole technologies, this is a role that rewards creativity, rigour, and continuous learning.

🧠 Your Responsibilities

Build and refine 3D CFD models for current and next-gen tools
Validate simulations with test/field data to ensure accuracy
Analyse and optimise internal fluid behaviours and tool performance
Collaborate with mechanical design, manufacturing, and supply chain teams
Support test rig design and execution for model validation
Prepare and present findings clearly to stakeholders
Contribute to obsolescence reviews and product lifecycle support
Stay current with emerging tech relevant to complex fluid systems
Occasional international travel to support global projects

✅ What We're Looking For

BEng or MEng in Engineering or related discipline
Minimum 5 years' CFD or fluid dynamics experience
Proficiency with Ansys Fluent, 3D CAD (ideally Creo), and MS Office
Strong grasp of fluid mechanics, turbomachinery, and hydraulics
Skilled in simulation interpretation, model validation, and analysis
Excellent communication and collaboration skills
Organised, self-motivated, and able to manage priorities

⭐ Bonus Experience

Downhole or non-Newtonian fluid experience
Python (e.g., PyFluent), Matlab, or open-source CFD tools (e.g., OpenFOAM)
Broader simulation background: FEA, stress/dynamics, system modelling

🎁 Why Apply?

Competitive salary + benefits
25 days holiday
Private medical, life assurance, and pension
Regular team socials
Flexible work arrangements
Supportive environment for technical and professional development
