Job Description

DropLab is a multidisciplinary company focused on development on microfluidics systems, based in Toronto offering full-spectrum solutions: cartridge design, system design (mechanical + microelectronics), industrial design, rapid prototyping and manufacturing.

Our work bridges biology, mechanical engineering, electronics, firmware and manufacturing -- providing an ideal environment for hands-on engineers who like to build, iterate and scale.

About the Role

We're looking for a hands-on Cartridge Development Engineer

to join our diagnostics team. You'll help design, prototype and scale microfluidic cartridges for diagnostic/assay applications -- working at the intersection of microfluidics, electronics and assay integration. You'll translate experimental designs into manufacturable devices.

What You'll Do

Design and prototype

microfluidic cartridges

for diagnostic assays, working through concept ? CAD ? prototype ? benchtop test. Use

CAD

for modelling cartridge geometries and assemblies. Build, test and iterate prototypes -- using 3D printing, laser cutting, machining, bonding. Collaborate with assay scientists to ensure cartridge designs align with reagent workflows -- familiarity with biochemistry (reagents, surface interactions) is a plus. Work on

design-for-manufacture (DfM) and design-for-assembly (DfA)

: help transfer prototypes into scalable manufacturing (injection moulding, bonding, assembly). Engage in problem-solving, root-cause analysis, iteration cycles and cross-disciplinary teamwork.

What We're Looking For

BS or MS in Mechanical, Biomedical, Bioengineering or equivalent. 3+ years hands-on experience in microfluidic or diagnostic system development (cartridges, fluidic modules). Strong CAD skills (Fusion 360 or equivalent). Experience with CFD simulations of microfluidic flows. Comfortable prototyping: 3D printing, machining, bonding, fluidic testing. Some experience or strong interest in electronics/system integration is a great asset. Ability to collaborate across biology (assays), mechanics (cartridge), electronics (sensors/controllers). Resourceful, detail-oriented, thrive in fast-paced hands-on R&D environment.

Nice to Have

Background in biochemistry or assay development -- understanding reagent behaviour, surface chemistry, or biological workflows. Previous experience transferring prototypes into manufacturable products (injection moulding, tooling, assembly lines). Experience with polymer materials, adhesives, membranes, and fluidic component fabrication. Understanding of electronics/hardware integration (e.g., sensors, microcontrollers) in a fluidic system.

Why You'll Love Working Here

Opportunity to work at the cutting-edge of diagnostics and microfluidics -- where mechanical, electronic, fluidic and biological components converge. A team environment that values hands-on building, experimentation, iteration, and visible impact. Working for DropLab -- where you'll be part of end-to-end design: from concept through prototype to scale-up manufacturing. Flexible, dynamic, and collaborative culture. Excellent group benefits and competitive compensation package.
