Mechanical Prototyping Engineer

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. What You’ll Be Doing * 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 Who You Are * 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 Preferred Experience * 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
