Remote Principal Mechanical Engineer - Thermal Systems

Our client, What Jobs Direct, is seeking an accomplished Principal Mechanical Engineer with expertise in Thermal Systems for a fully remote, senior-level position. This is a premier opportunity for a seasoned engineer to lead critical thermal management design efforts for complex products and systems, working entirely from a remote location. You will be responsible for developing innovative thermal solutions, conducting in-depth analysis, and guiding design teams.

The ideal candidate possesses a profound understanding of heat transfer principles, extensive experience with thermal modeling and simulation tools, and a proven ability to drive technical excellence in a remote-first environment. If you are a recognized expert in thermal engineering and thrive in an independent, challenging role, we encourage you to apply. This role is associated with
** Upington, Northern Cape, ZA**, but is fully remote.

• Lead the design, analysis, and optimization of complex thermal management systems for high-performance applications.
• Develop and validate advanced thermal models using CFD and other simulation tools to predict system performance.
• Define thermal requirements and specifications for new products and systems.
• Conduct comprehensive thermal analysis, including natural and forced convection, conduction, radiation, and phase change heat transfer.
• Oversee the selection and integration of thermal components such as heat sinks, fans, pumps, and heat exchangers.
• Collaborate virtually with cross-functional engineering teams (electrical, mechanical, systems) to ensure integrated thermal solutions.
• Mentor and provide technical leadership to junior and mid-level mechanical engineers in the thermal domain.
• Develop and implement best practices for thermal design and testing methodologies.
• Evaluate emerging thermal management technologies and propose their adoption where beneficial.
• Author and present detailed technical reports and findings to management and stakeholders.
• Contribute to strategic R&D planning and technology roadmap development for thermal systems.

• Ph.D. or Master's degree in Mechanical Engineering with a specialization in Thermal Sciences or Heat Transfer.
• A minimum of 10 years of progressive experience in mechanical engineering, with at least 5 years focused specifically on thermal system design and analysis.
• Expert proficiency in CFD software (e.g., ANSYS Fluent, STAR-CCM+) and thermal analysis tools.
• Deep understanding of thermodynamics, fluid dynamics, heat transfer phenomena, and material properties relevant to thermal applications.
• Proven track record of successfully designing and implementing thermal solutions for challenging engineering problems.
• Experience with laboratory testing and validation of thermal systems.
• Exceptional analytical, problem-solving, and critical thinking skills.
• Outstanding leadership, communication, and interpersonal skills, essential for remote team collaboration and guidance.
• Demonstrated ability to lead complex projects independently and deliver high-quality results in a fully remote setting.

• Top-tier compensation package, including base salary and significant performance bonuses.
• Executive-level benefits package, including comprehensive health, retirement, and life insurance.
• Generous allowance for professional development, training, and conference attendance.
• Significant autonomy and impact in a senior technical leadership role.
• A dynamic and innovative remote work culture.
• Flexibility of a 100% remote position.
