Type: Full-time | Experience: 1–3+ years

About the role: You'll own schematic PCB bring-up for our next-gen industrial data gateway. You'll design reliable power, digital, and sensor interfaces and work closely with firmware and test to ship production-ready hardware.

What you'll do

• Own schematics, component selection, and PCB constraints for MCU/SoC, power, and I/O.
• Design robust power rails (DC-DC, sequencing, inrush/ripple control) for RF/MCU loads.
• Integrate common industrial interfaces (e.g., digital inputs, analog 0–10 V / 4–20 mA, pulse counters, Modbus/RS-485).
• Generate fab & assembly packs (Gerbers, BoM with alternates, CPL, panel/stencil), and drive DFM/DFT with EMS partners.
• Bench bring-up (oscilloscope, logic analyzer), debug EMI/ESD/surge issues, and create programming/test jigs.

Must-have requirements

• Strong mixed-signal design for embedded products, from schematic to production.
• PCB layout constraints for power integrity, return paths, decoupling, and differential pairs.
• Hands-on with test equipment (DSO, power analyzer, function generator, electronic load).
• Clear documentation habits (BoM with ALTs, test notes, release packs).

Good to have

• Experience with cellular or other RF modules, isolated interfaces, safety/creepage practices.
• Familiarity with compliance basics (ESD/surge), reliability testing, and fixture design.

Tools

Altium/KiCad (or equivalent), LTspice/PI tools, basic Python for test scripts.
