About Submer At Submer, we are redefining data center cooling with innovative liquid immersion technology. We empower global teams to build sustainable, high-performance data centers. Our Taiwan team will drive the next generation of DLC projects.

What Impact You Will Have As a Senior Mechanical Engineer on the DLC Product team, you’ll lead the end-to-end design and development of advanced direct liquid cooling (DLC) systems for data centers. You’ll play a key role in translating performance and reliability targets into scalable mechanical solutions, collaborating across disciplines to bring next-generation cooling technologies from concept to production.

What You’ll Do

• Own the mechanical architecture and design of DLC systems, including cold plates, manifolds, enclosures, and rack-level integration.
• Collaborate with thermal, electrical, and controls teams to optimize overall system efficiency and reliability.
• Conduct CFD and FEA simulations to validate thermal, structural, and flow performance.
• Drive design-for-manufacturing (DFM) and design-for-assembly (DFA) initiatives with vendors and fabrication partners.
• Support prototype builds, performance testing, and design iteration cycles.
• Document design specifications, test results, and release packages for production.
• Provide mentorship and technical direction to junior and mid-level engineers.

What You’ll Need

• Bachelor’s or Master’s degree in Mechanical Engineering or a related field.
• 7+ years of mechanical design experience, preferably in thermal management or data center hardware.
• Proficiency in CAD tools (SolidWorks, Creo, or similar) and simulation tools (Ansys, COMSOL, or equivalent).
• Strong understanding of fluid dynamics, heat transfer, and materials for cooling systems.
• Proven experience taking products from concept through production.
• Excellent communication and documentation skills in English; Mandarin proficiency is a plus.

Our job titles may span more than one job level. The actual base pay is dependent on a number of factors, such as transferable skills, work experience, business needs and market demands.

What We Offer

• Attractive compensation package refleting your expertise and experience.
• A great work environment characterised by friendliness, international diversity, flexibility, and a hybrid-friendly approach.
