Principal Hardware Engineer Jobs (NOW HIRING)

Job Title: Principal Hardware Engineer

Job Description

The Principal Hardware Engineer serves as a senior technical leader responsible for the design, architecture, development, and full lifecycle ownership of advanced high-speed hardware products. This role focuses on driving hardware engineering excellence, leading complex product development initiatives, and enhancing existing high-speed communications solutions. The engineer will provide technical leadership and mentorship to junior and mid-level engineers while guiding architecture decisions and influencing cross-functional teams. The position emphasizes deep, hands-on hardware expertise and technical leadership rather than formal people management responsibilities.

Responsibilities

• Lead the end-to-end design and development of advanced hardware products, with a focus on high-speed communications systems using PCIe and Ethernet-based architectures.
• Own the full hardware product lifecycle from concept and architecture through detailed design, development, qualification testing, validation, and product release.
• Define and drive hardware architecture decisions for complex mixed-signal systems, including analog, digital, and high-speed interfaces.
• Provide technical leadership across projects, setting direction for hardware design approaches and ensuring engineering best practices.
• Mentor junior and mid-level hardware engineers, offering guidance on design methodologies, troubleshooting, and product development processes.
• Influence cross-functional teams by collaborating closely with other engineering disciplines and stakeholders to ensure successful product delivery.
• Design hardware for high-speed digital systems and address the specific design challenges associated with PCIe, Gigabit Ethernet, 10 Gigabit Ethernet, and higher-speed networking architectures.
• Lead EMI and EMC-related product design activities, including designing for EMI compliance, performing EMC troubleshooting, and implementing mitigation strategies.
• Oversee and participate in product qualification testing activities to ensure compliance with performance, reliability, and regulatory requirements.
• Ensure robust hardware designs that meet product requirements for signal integrity, power integrity, reliability, and manufacturability.
• Continuously improve existing hardware platforms by driving enhancements to performance, reliability, and feature sets.
• Serve as a recognized engineering leader within project teams, championing sound technical decisions and high-quality hardware engineering standards.

Essential Skills

• 15+ years of hardware engineering experience, with a strong preference for 15–20+ years and multiple complete product development cycles.
• Demonstrated progression into sr technical leadership roles, including leading technical direction and architecture for complex hardware products.
• Extensive experience designing high-speed communications hardware that utilizes PCIe, Gigabit Ethernet, 10 Gigabit Ethernet, and higher-speed networking architectures.
• Deep understanding of the design challenges associated with high-speed digital systems, including signal integrity and timing considerations.
• Proven technical leadership experience, including mentoring junior and mid-level engineers and influencing cross-functional engineering teams.
• Hands-on EMI and EMC product design experience, including designing for EMI compliance, EMC troubleshooting, and mitigation activities.
• Comprehensive full product development lifecycle experience, demonstrating ownership from concept and architecture through design, development, qualification testing, validation, and product release.
• Strong experience in complex hardware development, with direct responsibility and ownership of product-level designs.
• Experience with product qualification testing and compliance activities for hardware products.
• High-speed networking hardware experience, specifically in Ethernet-based products and PCIe-based systems.

Additional Skills & Qualifications

• Mixed-signal design experience, including analog design, digital design, and mixed-signal architectures, expected for principal-level candidates.
• Experience in telecommunications, networking, industrial electronics, or commercial hardware products environments.
• Exposure to embedded software is viewed positively, particularly when combined with strong hardware expertise, although it is not required.
• Familiarity with FPGA technologies is beneficial, provided the primary strength remains in hardware design and product ownership.
• Demonstrated ability to serve as a recognized engineering leader without relying on formal people management authority.
• Track record of successfully guiding multiple hardware products through development, qualification, and release.

Work Environment

The role operates in a professional engineering environment focused on advanced hardware and high-speed communications product development. The Principal Hardware Engineer works closely with cross-functional teams of hardware specialists and other engineering disciplines to deliver complex, Ethernet- and PCIe-based products. The environment emphasizes rigorous product qualification, EMI/EMC compliance, and full lifecycle ownership from concept through release. Work is primarily office and lab-based, involving design activities, hardware bring-up, troubleshooting, and collaboration on product architecture and validation. The culture values deep technical expertise, hands-on problem solving, and mentorship, encouraging experienced engineers to lead by example and elevate overall engineering excellence.
