Remote Principal Mechanical Engineer - Thermal Systems

About the Role

Our client, WhatJobs 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.

Key Responsibilities

• 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.

Requirements

• 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.

Benefits

• 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.
