Job Title: Hardware Design Engineer

Job Description

This role focuses on end-to-end ownership of complex digital hardware designs, from circuit and schematic development through PCB layout review and high-speed signal integrity analysis. The Hardware Design Engineer will work on multi-layer boards, contribute to redesigns to resolve existing issues, and collaborate closely with firmware, software, test, and mechanical engineering teams to deliver robust, production-ready hardware solutions.

Responsibilities

• Design digital circuits and develop detailed schematics for complex electronic systems.
• Review and refine schematics to ensure correctness, robustness, and compliance with design requirements.
• Lead and review PCB layout activities, with a focus on high-speed design best practices and manufacturability.
• Use Altium for schematic capture and PCB layout design, ensuring consistency and accuracy across design artifacts.
• Perform simulations using HFSS to evaluate and optimize high-frequency and high-speed behavior of designs.
• Redesign existing boards and circuits to identify, troubleshoot, and resolve performance or reliability issues.
• Design and support multi-layer boards, typically 4–8 layers and occasionally up to 10 layers, balancing signal integrity, power integrity, and layout constraints.
• Own the hardware design lifecycle, including concept, design, review, validation, and support into production.
• Integrate and validate DDR2/DDR3/DDR4 memory interfaces and ensure stable operation under target conditions.
• Design and validate interfaces for various high-speed peripherals such as HDMI, DisplayPort, USB-C/USB 3.x, DVI, 3G/12G-SDI, SFP/SFP+ transceivers, Ethernet (1G/10G), PCIe, LVDS, and MIPI.
• Interface hardware designs with microcontrollers, ensuring proper connectivity, timing, and system-level functionality.
• Implement and verify high-speed signals, interfaces, and buses, including TMDS, DDR, SDRAM, and Ethernet, with careful attention to length matching, differential pairs, and controlled impedance routing.
• Analyze and mitigate signal integrity and power integrity issues, including crosstalk and return path concerns, using SIPI analysis and eye diagram evaluation.
• Collaborate with firmware, software, test, and mechanical engineers to ensure seamless integration of hardware into complete systems.
• Participate in design reviews and provide technical guidance on high-speed design techniques and best practices.
• Support testing and debugging activities, including board bring-up and validation of high-speed interfaces and multimedia/video paths.

Essential Skills

• Proven experience in digital hardware design, including circuit design and schematic development.
• Hands-on experience with PCB layout design and review, particularly for high-speed digital boards.
• Proficiency using Altium for schematic capture and PCB layout.
• Experience designing and supporting multi-layer PCBs, typically in the 4–8 layer range, with occasional designs up to 10 layers.
• Strong experience with DDR2, DDR3, and DDR4 memory interfaces, including layout and timing considerations.
• Experience working with high-speed peripherals such as HDMI, DisplayPort, USB-C/USB 3.x, DVI, 3G/12G-SDI, SFP/SFP+ fiber optic transceivers, 1G/10G Ethernet, PCIe, LVDS, and MIPI.
• Experience interfacing hardware designs with microcontrollers.
• Demonstrated ability to design with high-speed signals, interfaces, and buses, including TMDS (150 MHz–500 MHz) and 10 Gigabit Ethernet.
• Expertise in high-speed design techniques such as differential pair routing, length matching, controlled impedance routing, and return path optimization.
• Experience with signal integrity and power integrity analysis, including crosstalk mitigation, eye diagram analysis, and SIPI analysis.
• Familiarity with multi-gigabit differential interfaces and their layout and validation requirements.
• Experience using HFSS or similar tools for high-frequency and high-speed simulations.
• Ability to take ownership of hardware designs throughout the product lifecycle, from concept through validation.

Additional Skills & Qualifications

• Experience with video or multimedia products, particularly those involving high-speed video interfaces.
• FPGA experience, including integrating FPGAs into hardware designs and working with associated high-speed interfaces.
• Experience in electronics, electrical engineering, or a related discipline.
• Experience working within cross-functional engineering teams that include firmware, software, test, and mechanical disciplines
