We’re Flowgreens - an unapologetically bold wellness startup fusing science, nature, and sensory design. Our first product, ScentXpresso, is the world’s first in-shower smart aromatherapy diffuser. It’s intuitive, elevated, and engineered to deliver calm at the press of a button.

We’re now entering the next phase - rapid prototyping and hardware iteration—and we’re looking for a hands-on Mechanical Prototyping Engineer to help bring this vision to life, piece by piece.

• Assemble and modify functional prototypes, following CAD files, exploded views, or engineering walkthroughs

• Test core mechanical systems—from mist diffusion and scent delivery to seals, thermal performance, and component alignment

• Use SolidWorks to review CAD assemblies, interpret tolerances, and suggest real-world amendments for improved fit, function, or manufacturability

• Diagnose issues and recommend refinements across form, function, and DFM

• Document test procedures and outcomes using structured logs and annotated imagery

• Work closely with product and design leads to iterate rapidly on evolving hardware

• Support material testing, tolerancing reviews, and vendor samples as needed

• Assist in the transition from prototype to pilot production, including DFM feedback

• A hands-on mechanical thinker who enjoys building and breaking things in equal measure

• Experienced with physical prototyping, fixtures, and benchtop testing

• Skilled in interpreting technical drawings and translating them into working assemblies

• Proficient in SolidWorks for CAD reviews and minor design adjustments

• Comfortable using workshop tools (hand tools, calipers, multimeters, etc.)

• Precise, process-driven, and able to manage multiple test iterations at once

• Open-minded, solutions-focused, and excited to shape a new product category

• Experience with consumer hardware prototyping (wearables, IoT, wellness devices, etc.)

• Familiarity with IP-rated sealing, small-scale fluid systems, or mist/atomisation tech

• Understanding of plastics, silicone, and soft tooling

• Comfortable reviewing or editing files in SolidWorks or similar CAD systems

• Able to write or adapt simple test plans or SOPs
