Overview

NORTH-WEST UNIVERSITY (POTCHEFSTROOM CAMPUS)

FACULTY OF ENGINEERING – HySA INFRASTRUCTURE

POSITION NUMBER: P003293

VACANCY: SENIOR SUBJECT SPECIALIST

PEROMNES GRADE: 7

EMPLOYMENT TYPE: FIXED-TERM APPOINTMENT WITH BENEFITS

PURPOSE OF THE POSITION

To provide strategic expertise in computational fluid dynamics (CFD) and digital twin development to advance HySA Infrastructure’s research on hydrogen recombination technology, hydrogen safety, and PEM water electrolysis. The position will build critical capacity in numerical modelling — a niche yet globally essential field — to enable predictive design, risk assessment, and performance optimisation of hydrogen systems. The candidate will strengthen NWU reputation in hydrogen R&D by leading high-impact CFD research, supervising postgraduate students, fostering interdisciplinary collaboration, and developing competitive digital simulation capabilities for the South African Hydrogen Road Map and international hydrogen projects.

Minimum Requirements

• A doctor of philosophy in Engineering with Chemical Engineering (NQF level 10).
• A minimum of three (3) years’ post-doctoral experience in Hydrogen Energy.
• A minimum of five (5) years’ experience in:
• CFD modelling, including turbulence, multiphase flows, mass and heat transfer, combustion, and reactive transport (Hydrogen-related experience would be an advantage).
• Coordinating technical input across different disciplines and cultures and leading engineering projects to deliver outputs and objectives (students supervision experience would be an advantage).
• Hydrogen safety, catalytic and electrochemical processes (PARs and PEM electrolysis).
• Experimental technics, including catalytic reactors, hydrogen detectors and gas analysers, flow controllers, etc.
• Publishing and communication with journal editors.

Job Description

KEY RESPONSIBILITIES:

Advanced CFD Research & Development

• Lead CFD-based R&D for hydrogen recombination systems, PEM electrolysis, and hydrogen safety through technology development and demonstration (TD&D).

Research Publications & Academic Citizenship

• Publish research in accredited international journals and present findings at leading conferences, workshops and exhibitions.

Postgraduate Supervision & Leadership

• Supervise postgraduate students (MSc/PhD), guiding their research in numerical modelling and hydrogen safety/energy systems. Mentor junior researchers, contribute to team cohesion, and promote knowledge transfer.

Projects Development

• Collaboration with industry, national stakeholders, and international partners to establish HySA Infrastructure portfolio in CFD modelling for hydrogen systems.

Team Contribution & Capacity Building

• Contribute to interdisciplinary and cross-cultural research teams, ensuring numerical modelling supports experimental and applied projects. Contributing to public awareness on the subject.

Key Functional/Technical Competencies

• Strong experience in CFD codes such as Star-CCM, safety analysis, and numerical methods.
• Scopus H-index: at least 7.
• Expertise in safety validation (hydrogen safety in confined spaces would be an advantage).
• A drive to make a difference through decarbonisation and green hydrogen technology.
• Be qualified for NRF rating/or applied for.
• Proven track record for scientific papers review.
• Track record of supervising postgraduate students and publishing in international journals.

Key Behavioral Competencies

• Ability to work effectively in a cross-cultural team and disciplines.
• Strong leadership and mentoring skills; ability to inspire students and junior researchers.
• Quick learner, excellent problem-solving skills and attention to detail.
• Committed to NWU’s values of academic freedom, inclusivity, excellence, and research ethics.

Remuneration

The annual total remuneration package will be commensurate with the level of appointment as advertised and in line with the NWU policy guidelines. International applicants must make arrangements for work authorization in RSA.
