Mechanical Engineer

About the Company

We are a group of inkjet technology experts with a shared passion for innovation, driven by mastery in Additive Manufacturing. flō is on a mission to transform the ophthalmic lens coating production process through our proprietary technology, providing immense value to ophthalmic laboratory manufacturers.

About the Role

Own mechanical design for subsystems of optical coating machines and supporting equipment.

Responsibilities

• Architect and implement linear/rotary axes (guides, screws, belts, bearings, couplings, lubrication, alignment, guarding).
• Design for controlled airflow and nitrogen management (flows, routing, filtration, purge/pressure strategy, condensate considerations).
• Design and control for IDS (Ink Delivery Systems) for inkjet printing systems.
• Engineer thermal solutions (heating/cooling layouts, heat sinks/plates, insulation, expansion management).
• Produce clean CAD (SolidWorks or Autodesk) and fully detailed 2D drawings with correct GD&T, fits, and surface specs.
• Run tolerance stack-ups and DFM/DFA reviews; choose materials and finishes appropriate for cleanliness and durability.
• Specify and source components; build structured BOMs; collaborate with suppliers on CNC, sheet metal, turning, and other processes.
• Rapidly prototype and iterate (bench tests, assembly bring-up); support technicians during build, integration, and verification.
• Document rigorously (ECOs, test reports, assembly instructions) and communicate cross-functionally with controls, process, and production teams.

Qualifications

• ~10 years professional experience in mechanical design for machinery, equipment, or precision assemblies.
• BSc or higher in Mechanical Engineering.

Required Skills

• Mastery of SolidWorks or Autodesk (Inventor/Fusion) for complex assemblies and drawing creation.
• Proven DFM for CNC milling/turning, sheet metal, bending, welding, and appropriate fastening/joining.
• Strong command of GD&T (ASME Y14.5 or ISO 1101), tolerance analysis, and fits for motion and sealing interfaces.
• Practical experience implementing motion axes (component selection, alignment, preload, stiffness, backlash control).
• Working knowledge of airflow / nitrogen routing and thermal management in machinery.
• Comfortable on the shop floor: metrology tools, bring-up, troubleshooting, and design changes based on test evidence.
• High degree of self-sufficiency and fluent in English.

Preferred Skills

• Printing system design.
• Exposure to optical equipment, lens handling/fixturing, cleanliness-by-design, or coating system environments.
• Light FEA for sanity checks, vibration/stiffness estimation, or thermal evaluations.
• Familiarity with PDM/PLM, ECO workflows, and structured BOM management.
• Experience delivering products that reached market production (industrial machinery or capital equipment).
