Job Description

We are seeking a motivated, detail-oriented Microfluidics and

Device Engineer to join our team and contribute to the development of microfluidic cartridges • using isothermal amplification methods, integrated heating, and optical readout.

Key Responsibilities

  • Design, develop, and optimize isothermal POCT microfluidic cartridges and devices with optical detection systems.
  • Perform injection molding process development and optimization for plastic microfluidic components to support scalable product manufacturing.
  • Collaborate with cross-functional teams (including IVD reagent development) on the co-development of microfluidic chips and integrated diagnostic platforms.
  • Participate in external R&D collaborations, including occasional business travel to support co-development projects.
  • Conduct hands-on prototyping, testing, and troubleshooting of mechanical, fluidic, and optical subsystems.
  • Maintain accurate documentation of designs, experiments, and test results in • compliance with product development processes.

Requirements • Bachelor’s degree or higher in Mechanical Engineering, Biomedical Engineering,

Optical Engineering, Electrical Engineering, or a related field.

  • Minimum 2 years of industry experience in biomedical device or IVD product development, with end-to-end project involvement.
  • Strong proficiency in CAD software (SolidWorks preferred), with expertise in plastic part design, material selection, and design for injection molding/manufacturability.
  • Hands-on experience with rapid prototyping techniques, including CNC machining,

laser cutting, 3D printing, and assembly of microfluidic devices.

  • Practical knowledge of microfluidics, fluid dynamics, and thermal management for isothermal amplification (heating control).
  • Experience with optical systems for readout/detection in diagnostic devices is highly preferred.
  • Familiarity with IVD regulatory requirements and quality standards (e.g., ISO 13485)

is a plus.

  • Knowledge of electronics or basic instrumentation is advantageous.
  • Excellent organizational skills, attention to detail, and ability to deliver high-quality work under tight timelines.
  • Strong communication and collaboration skills; ability to thrive in a fast-paced, crossfunctional environment.
  • Proficiency in both English and Chinese (Mandarin/Cantonese) is a significant advantage.
