Hardware Design Engineer

Nexite develops next-generation retail IoT infrastructure for retail industry. We are looking for a hands-on Hardware Design Engineer to own the full hardware lifecycle — schematic capture, PCB layout, mixed signal circuit design, power architecture, bring-up, and regulatory certification — across current and next-generation hardware.

Requirements: • B.Sc. in Electrical Engineering – mixed-signal focus. • 3-5 years of hands-on PCB design experience for production hardware of analog and digital design, including 2 years with RF circuits at 900 MHz and/or 2.4 GHz. • Proficiency in Altium Designer or OrCAD/Allegro for multi-layer high-density layout: controlled impedance, differential pairs, and RF routing. • Experience with multi-domain power architectures: DCDC converters, LDOs, power sequencing circuits, and IO level compatibility analysis. • Experience digital hardware stack: NXP i.MX RT MCU schematic and BGA layout, Ethernet PHY circuit • Solid RF fundamentals: S-parameters, impedance matching, Smith chart, link budgets, directional couplers, as well as LNA and PA operation. • Hands on experience with lab equipment: oscilloscope, logic analyser, VNA, and spectrum analyser. • Familiarity with EMI/EMC design practices and experience supporting hardware through FCC, CE, or equivalent certification. Advantage • Experience with angle of arrival concepts (such as BLE AoA) and the associated hardware design/constraints. • Experience with NXP MCUs hardware constraints. • Experience designing PoE (IEEE 802.3af/at) and isolated flywheel buck power delivery circuits. • Experience with HyperRAM and high-speed PCB design. • Experience with Ethernet hardware design and manufacturing RF test fixtures.
