Senior Mechanical and Industrial Design Engineer

You will lead the industrial and mechanical design of next-generation Stripe Terminal payment devices, shaping their form, feel, usability, and structural performance from early concepts through mass production. You will partner with cross-functional teams and suppliers to deliver manufacturable, high-quality hardware, including enclosure design, color, material, and finish specifications, packaging, validation, and production readiness.

Industrial design

• Lead ideation and concept development through rapid hand sketching, digital sketching, and physical foam or 3D-printed models to explore form factors early in the product lifecycle.
• Define the visual and tactile design language of Terminal hardware, including proportion, form, surface transitions, button feel, and overall product character.
• Produce photorealistic product renders using KeyShot or similar tools to communicate design intent to cross-functional teams and executive stakeholders.
• Define and manage color, material, and finish (CMF) specifications. Work directly with suppliers to qualify target surfaces, textures, and coatings.
• Manage packaging design, working directly with suppliers to qualify final deliverables and the unboxing experience.
• Apply ergonomics and human factors principles to ensure products are intuitive and comfortable for a diverse range of users and environments.
• Maintain visual consistency and brand coherence across the Terminal hardware product family, in alignment with Stripe's design identity.

Mechanical engineering

• Design mechanical components and assemblies using SolidWorks or Creo, following professional engineering standards.
• Hands on experience in mechanical designs and drawings, assess manufacturability, and resolve technical problems.
• Lead and plan problem-solving activities using scientific approaches, such as tolerance analysis, computer-aided engineering (CAE) and finite element method (FEM) simulations, design of experiments (DOE), and physical prototyping.
• Independently analyze and verify mechanical designs, identify risks, and propose mitigations.
• Manage bill of materials (BOM) cost and design schedules from a mechanical engineering perspective.
• Prepare mechanical engineering deliverables, including BOMs, component specifications, and support for failure mode and effects analysis (FMEA) activities.
• Review Design fixtures and calibration processes for high-precision mechanical assemblies.
• Verify and qualify components in first-article builds from suppliers, and participate in pilot production.
• Produce and maintain engineering documents, including specifications, design-for-excellence (DFx) guidelines, technical reports, and gate-review packages.
• Partner with Quality and Reliability teams to support successful validation outcomes and improve hardware durability standards.
• Support product compliance and certification activities, including Payment Card Industry (PCI) and regulatory certifications.
