Senior Mechanical Design Engineer

Location: Istanbul, Türkiye — on-site Type: Full-time, permanent Team: Hardware Engineering — reporting to the Head of Hardware Design Engineering & Co-founder CAD: Onshape or SolidWorks — Creo a plus. Licence provided. About Tezzro At Tezzro, we're building Türkiye's first AI-powered Autonomous Retail OS — creating a truly checkout-free shopping experience. Our platform is as much hardware as software. AI systems, embedded electronics and precision-engineered mechanical hardware have to work as one product, installed in real commercial spaces and handled by the public every day. We are now hiring the senior engineer who will lead the mechanical engineering of that platform. About the role You will be our lead engineer for mechanical design. Not a pair of hands on someone else's drawings — the engineer whose judgement decides how our hardware is built. You turn requirements into designs . Functional and product requirements arrive as intent and constraints. You translate them into practical, efficient, manufacturable mechanical solutions. You see your design through from concept to production . Architecture, detailed design, analysis, drawings, supplier selection, first parts, and the revisions that come out of real testing — you stay with it to the end. You work shoulder to shoulder with hardware . Our hardware design engineer develops the custom PCBs and electronics that live inside your structures. You'll design those integrations together — enclosure envelopes, board mounting, display and connector interfaces, cable routing, thermal paths, and sealing where electronics meet the outside world. This is a genuine two-way collaboration: your mechanical constraints will change their board layout, and their electrical constraints will change your geometry. You set the standard . Tooling, processes, documentation practice, manufacturing partners, and how mechanical work gets done here — those are yours to define. The work is hands-on and it moves fast. You design it, you document it, you get it made, and you hold the finished part in your hands weeks later — not quarters later. What you'll do Develop complete mechanical designs — architecture through detail — for enclosures, structures, mechanisms and assemblies. Design precision sheet metal a workshop builds right the first time — accurate flat patterns, bend allowances, forming and weld details, realistic tolerances. Tolerance the design so it assembles — stack-ups on the dimensions that matter, fits, clearance and interference studies, and datums a workshop can measure from. Produce production-grade documentation — 2D drawing packs with GD&T and tolerances, BOMs with real sources, assembly and integration guides. Design sealed enclosures that keep moisture and heat where they belong — gasketing, sealed interfaces, thermal management. Design user-facing housings and surfaces to a consumer-product standard — flush, smooth, easy to clean, no exposed fasteners,…
