Senior EMC / Hardware Engineer

You are hiring a senior-level hardware design engineer who specializes in EMC troubleshooting and isolated PoE power design for networking and wireless products. This is a hands-on design role, not a compliance test operator. Atheer ACT is a Saudi deep-tech telecommunications company building carrier-grade 60 GHz and mmWave wireless infrastructure for high-throughput backhaul and enterprise connectivity. What they will do: This engineer will be responsible for diagnosing and fixing a live EMC compliance failure on the PoE port of an outdoor wireless radio product. Their work will directly impact the success of the current certification cycle. Key responsibilities include: Analyze EMC failure plots and identify root causes quickly. Redesign isolated PoE PD converters (IEEE 802.3bt Type 3/4). Design and tune magnetics: flyback transformers, common-mode chokes, isolation barriers. Optimize PCB layout for EMC performance: grounding, isolation, filter placement. Reduce conducted emissions on telecom ports (CISPR 32 / EN 55032 using ISN). Guide the product through full EMC certification, including retests. Work closely with hardware, RF, and compliance teams. Must-have experience: 8+ years of experience designing PoE power stages, solving EMC failures, and shipping telecom or networking hardware through certification. Bachelor's degree or higher in Electrical Engineering, Electronics, or a related field. Isolated PoE PD converter design compliant with IEEE 802.3bt Type 3 or Type 4. Flyback topology design and transformer construction. Common-mode choke selection under DC bias. CISPR 32 / EN 55032 conducted emissions testing on telecom ports using ISN. PCB layout for EMC performance.
