About this role

Who We're Looking For You are not just looking for a job — you're looking to build, innovate, and grow fast. You thrive in a dynamic environment, where no two days are the same. You enjoy being hands-on, solving real-world technical issues, and working closely with clients and a passionate internal team. We're looking for resourceful, self-driven engineers who take ownership and pride in their work — people who enjoy building something meaningful from the ground up. Key Responsibilities Perform technical setup, testing, installation, and commissioning of HBOT and oxygen systems at client locations. Conduct preventive and corrective maintenance; troubleshoot hardware and system faults (mechanical, electrical, air-oxygen systems). Work closely with R&D and product teams to improve system reliability, user experience, and integration. Assist in system design, prototyping, and engineering documentation. Provide technical support and training to clients, operators, and internal team. Ensure safety and regulatory compliance across all installations and engineering activities. You Should Have Diploma or Degree in Engineering (Mechanical, Mechatronics, or related). Solid hands-on technical skills — wiring, plumbing, electrical, system integration, or similar. Strong problem-solving mindset and initiative — you don't wait for instructions, you figure it out. Ability to communicate clearly with technical and non-technical stakeholders. Excellent attention to detail, especially in safety-sensitive environments. [Preferred but not mandatory] Experience with oxygen systems, medical equipment, or HVAC. What You'll Gain Direct exposure to high-tech wellness and the future of healthcare innovation. A front-row seat in scaling a Singapore-grown brand with global ambitions. Freedom to make your mark — we value ideas, not just job titles. Opportunities for regional travel, leadership, and career development. A dynamic, supportive, and ambitious team culture.
