Role summary Own the design, bring-up, and validation of electronics for multimedia systems (panel/receiver/scan boards), with emphasis on MCU control, LED driver chains, high-current power distribution, and EMC/ESD robustness.

Responsibilities Define system architecture for multimedia panels/modules (receiver/scan boards, hub interfaces, inter-panel connectors).

Schematic capture and layout guidance for multilayer PCBs; drive placement/routing to ensure good routability and SI/PI margins.

Select and integrate constant-current LED driver ICs; design row/column scan topologies (e.g., 1/8–1/64), PWM/gray-scale timing, global brightness control, and refresh ≥ 3,840 Hz.

Implement calibration hooks (per-panel uniformity, gamma/white-balance, mapping tables) and non-volatile storage strategy.

Power design: 5–48 V inputs, DC/DC (buck/boost), high-current 5/12 V buses, inrush/OR-ing, current sensing, thermal derating, and protections (OVP/OCP/OTP).

EMC/ESD/Surge hardening at the board and enclosure level (IEC 61000-4-2/-4-4/-4-5, CISPR 32/EN 55032); grounding, shielding, filtering, and panel-to-panel cabling design.

High-speed and robust links as needed (Gigabit Ethernet/LVDS/RS-485/isolated comms; HUB-style panel interfaces).

Build test fixtures and factory programming/jig interfaces; author EVT/DVT plans, scripts (Python preferred), and acceptance criteria.

Drive FA/RCAs on field returns; collaborate with suppliers (LED drivers, panels, power) and contract manufacturers to close issues and cost down.

Minimum Qualifications BS/MS in Electrical or Computer Engineering (or equivalent).

• 6+ years of hardware design in displays/LED drivers/embedded systems, including end-to-end ownership from schematic to MP.

Hands-on MCU experience: board bring-up, bootloaders, peripheral drivers, HW/FW integration, and debug (oscilloscope, logic analyzer, SWD/JTAG).

Solid knowledge of constant-current LED drivers, scan multiplexing, PWM/gray-scale generation, and timing closure for large LED matrices.

Proven PI/SI fundamentals and power design skills (synchronous buck, layout for high current, loop stability, transient response).

Practical EMC/ESD design experience and successful compliance history (IEC 61000-4-2 contact ±8 kV / air ±15 kV or higher).

Proficiency with schematic/layout tools (Altium/OrCAD or similar) and versioned documentation (BOMs, specs, ECNs).

Preferred Qualifications Experience with LED video-wall ecosystems (receiver/scanner cards, HUB interfaces, calibration workflows).

Familiarity with common LED driver families (e.g., MBI/ICN/Novatek or similar) and large-array current/thermal budgeting.

PoE (802.3af/at/bt), isolated DC/DC, or high-power backplanes.

Manufacturing-oriented design (DFM/DFT), fixture development, boundary-scan, and factory test scripting.

Cross-functional communication (PM/ID/ME/FW/PDM) in English; vendor management experience.

Nice to have Camera-based color/brightness calibration experience; data pipelines for per-pixel/region corrections.

Experience hardening designs against ESD during handling (e.g., on-cell touch/guard-ring strategies, chassis-to-logic RC links).
