R&D Engineer

Rapidemic is seeking a Junior R&D Engineer to join our Engineering team and contribute to the development of next-generation in vitro diagnostic (IVD) devices. As an R&D Engineer you will support the design, prototyping, characterization, and verification of integrated diagnostic systems spanning fluidics, thermal management, optics, electronics, and consumable components. This is a hands-on role suited to a detail-oriented, early-career engineer who thrives in a fast-paced, multidisciplinary environment and is eager to grow technical depth across hardware development and design controls within a regulated medical device setting (ISO 13485). You will work alongside experienced engineers, and scientists, gaining direct exposure to the full development lifecycle from concept exploration to design transfer.

Rapidemic is a molecular diagnostic company based in Leiden, the Netherlands, founded in 2021 with the mission to make quality diagnostics accessible to all, worldwide. The company’s laboratory facilities and offices are located in the beating heart of the Leiden Bioscience Park, where our team of 15 scientists, engineers, quality and regulatory experts and management team works to raise the bar in infectious disease diagnostics.

Our product platform, RapiDetect^TM is the world’s first equipment-free molecular diagnostic test capable of diagnosing infections in a single visit with lab-grade accuracy. Our first product under development, RapiDetect^TM CT/NG, breaks down barriers to test for patients with a suspected sexually transmitted infection.

Join us in shaping a future where every individual can access the care they need. Be part of the team that’s changing the face of molecular diagnostics and shaping a healthier tomorrow. We're seeking a motivated R&D Engineer to join our team, shape the company’s trajectory and bring this device to patients in need. Let’s build the future together at Rapidemic!

• Plan and execute design verification experiments, including writing test protocols, collecting and analyzing data, and producing clear technical reports.
• Generate and maintain CAD models, engineering drawings, and technical documentation in line with internal design control procedures.
• Support failure analysis, root cause investigation, and design iterations based on experimental and field feedback.
• Work cross-functionally with other teams to integrate subsystems into products.
• Maintain accurate records in the design history file (DHF) and contribute to risk management activities (ISO 14971) under the guidance of senior engineers.
• Help maintain a safe, organized, and productive lab environment.
• Participate in project meetings, contribute ideas, and present findings.

• Educational Background:
• B.S. or M.S. degree in Mechanical, Biomedical, Chemical Engineering, Applied Physics, or closely related disciplines.
• 0-2 years of relevant experience (internship, thesis project, and student team work count); we welcome applications from recent graduates.
• Required Skills:
• Solid foundation in engineering fundamental; mechanics, heat transfer, fluid dynamics, or basic electronics.
• Hands-on prototyping skills: experience with at least one CAD software (SolidWorks, Fusion 360, or equivalent), 3D printing, basic machining, soldering, or breadboarding.
• Comfortable with experimental work, defining test setups, executing measurements, and interpreting data.
• Strong with data analysis and scientific data analysis tools (Python, MATLAB, or equivalent) and standard office tools.

• Familiarity with design controls, risk management (ISO 14971), and verification & validation methodology.
• Experience with one or more of: microfluidics, low-volume liquid handling, thermal control systems, or embedded electronics.
• Knowledge of statistics for engineering (DOE, GR&R, capability analysis); coursework or certification (Six Sigma Green Belt) is a plus.
• Familiarity with molecular biology workflows at a conceptual level. Sufficient to communicate effectively with assay team members.
• Experience with version-controlled documentation, PLM systems, or electronic QMS tools.
• Awareness/exposure to design for manufacturing (DFM) and design for assembly (DFA) principles. 

• A competitive salary.
• An incredible learning experience working in a growing start-up.
• A relaxed work atmosphere.
• The opportunity to explore and test your own ideas.
• A working experience in a European hub for life sciences innovation.
• A work experience in the diagnostics industry.
