Jobs at Delart

Lead signal and power integrity analysis for high-speed digital interfaces up to 448Gbps. Perform electromagnetic, PDN, eye diagram, jitter, noise, and S-parameter simulations using industry tools. Develop guidelines for impedance control, transmission lines, PCB stack-ups, and manufacturing processes. Collaborate with PCB layout engineers and fabrication vendors to optimize server, data center, and networking hardware designs, while documenting technical findings and recommendations.

Manages HR operations, Hong Kong payroll coordination, MPF administration, immigration cases, employee records, onboarding, finance coordination, vendor relationships, and daily office and laboratory operations. Serves as the primary onsite administrative and security contact, overseeing access control, visitors, supplies, equipment, safety protocols, and local service providers. Supports the Hong Kong entity independently while coordinating with regional and global teams.

Performs electromagnetic, signal integrity, and power integrity simulations for high-speed digital interfaces up to 448Gbps. Analyzes PAM4 and NRZ links, eye diagrams, jitter, noise, S-parameters, PDNs, impedance control, transmission lines, and PCB stack-ups. Develops design guidelines, documents simulation results, correlates simulations with measurements, and collaborates with PCB layout engineers and fabrication vendors on server, data center, and networking hardware.

Analyze cellular network performance and application-layer QoE, identify bottlenecks, build scalable data-processing pipelines, and develop analytics solutions using Python, R, and SQL. Partner with network operators to collect, validate, and analyze large-scale real-world network data, supporting optimization of mobile network services.

Design, deploy, configure, troubleshoot, and optimize high-speed Ethernet networks using Arista, Cisco, and whitebox platforms. Manage Layer 2/3 networking, IPv4/IPv6 routing, QoS, RDMA/RoCE, Linux networking services, and data center or HPC infrastructure. Automate configuration and deployment with Bash and Python while supporting ONIE, SONiC, SAI, PXE, DNS, and DHCP environments. Preferred experience includes network automation, infrastructure as code, telemetry, software-defined networking, and low-latency performance tuning.

Own the BSP firmware lifecycle for consumer wearable and AI devices, including board bring-up, bootloaders, kernels, device drivers, device trees, peripherals, diagnostics, and recovery systems. Lead hardware validation from prototypes through mass production, debug issues with vendors and cross-functional teams, support manufacturing sites, and document bring-up and validation processes.

The Wireless Systems Characterization Engineer will integrate and characterize wireless systems, develop test plans, conduct performance testing, and analyze data for consumer electronics products.

Serve as the APAC technical representative bridging firmware, software, and hardware teams. Lead Qualcomm RF bringup, driver and RF configuration tweaks, vendor triage (Qualcomm), and support CM factory and lab operations to ensure production quality and integration.

Lead WiFi/Bluetooth firmware integration for wearable devices, liaise with semiconductor vendors (notably Qualcomm), debug chipsets using Logcat/dmesg/QXDM, manage NVM/BDF and firmware deployment, support RF bring-up, validation and certification (SAR), develop Python/C/C++ test automation, and provide on-site factory and lab technical support.

Act as firmware lead for WiFi/Bluetooth in wearable devices: liaise with RF/antenna/validation/BSP teams and vendors, debug chipsets using Logcat/dmesg/QXDM, manage NVM/BDF and firmware integration on Qualcomm platforms, support on-site manufacturing and RF bring-up, and build automation/tools for diagnostics and factory tests.
