Lead Hardware Engineer

CONTEXT 250 local authorities rely on Vizzia's hardware - cameras, stations, accessories - deployed in the field, in real conditions, every day. By end of 2026, that number will be 450. Scaling from here is first and foremost a hardware challenge. The next product iterations need to ship on time, at industrial-grade quality, and with the technical foundations that will hold at scale. That's what this role is about. Vizzia has raised €30M in Series B and is accelerating. The Hardware R&D team covers the full stack — electronics, mechanics, firmware — and is looking for its technical anchor: someone who goes deep on architecture, sets the bar on engineering standards, and makes sure what leaves the lab actually survives the field. You'll report directly to David, Head of Hardware, and work across the hardware team as the senior technical WHAT YOU'LL DO 1. Architecture & technical decisions - Own the system architecture across electronics, mechanics, and firmware - making calls that balance performance, cost, and long-term maintainability - Drive technical choices on high-speed design, and embedded systems with a clear rationale - Anticipate EMC/CE/NDAA certification constraints from day one, not as an afterthought - Simplify where others add complexity. If a design can be cleaner, make it cleaner 2. Industrialization & quality - Integrate DFM/DFT constraints at design stage, not at pre-production review - Define and enforce validation plans that go beyond the lab: functional, environmental, EMC, field testing - Ensure industrial documentation is complete and production-ready: BOM, Gerber files, test reports, procedures - Control BOM costs and secure critical components through double sourcing - Run go/no-go reviews before each hardware release — and make the call 3. Technical standards & team elevation - Set the engineering bar for the hardware team: documentation, validation rigor, design reviews, best practices - Be the technical reference that junior and mid-level engineers come to when a problem is hard - Contribute to recruiting and upskilling the hardware team as it grows - Structure clean interfaces with Backend and Operations to prevent integration surprises WHO YOU ARE - You have strong hands-on experience in electronic design and embedded systems - You've shipped hardware products through the full cycle: prototype, industrialization, mass production, field deployment - You're genuinely comfortable with the three dimensions of hardware : electronics, mechanics, firmware, and don't see them as separate worlds - You have a real-world reliability obsession. Lab performance is table stakes. What matters is what happens at deployment - You can zoom in on a routing issue and zoom out to rethink an architecture , and you know when to do which - You make technical constraints legible to non-hardware stakeholders without dumbing things down If you've read this far, you're probably very interested in the role and/or Vizzia. We'd like to hear from you even if you feel ou don't check every box.
