Principal Design Engineer

About the role

Team Credo is seeking a principal technical leader to drive both hands-on digital ASIC design and strategic architecture direction for our High-Performance Network Interface IP portfolio. This role has direct impact on the interconnect infrastructure enabling next-generation AI and HPC systems. Depending on the candidate's strengths, the focus may span from leading RTL development and design execution to shaping product roadmaps, architecture requirements, and long-range technology investments.

The ideal candidate brings deep expertise in computing and communication systems -including memory subsystems, inter- and intra-chip interconnects, Ethernet, CXL, PCIe, UCIe, and UALink - and understands how these technologies support scalable AI infrastructure across accelerator, chiplet, and data center environments.

Base salary range is $140,000 - $230,000 a year. The base salary offer will depend on factors such as education, experience, training, skills, qualifications, and location. This position is also eligible for a discretionary bonus, equity and a full range of medical and other benefits.

Why Credo

• Purpose: We invest in what matters. From meaningful-future shaping projects to competitive compensation, we empower you to grow your career while making a lasting impact.
• People: Connection starts within. We collaborate, celebrate wins, and create an environment where everyone can do their best work.
• Possibilities: Our belief shapes what's next. Our technology powers the most reliable and energy-efficient connections around the world - and our team powers new products and markets that come next.

Responsibilities

• Lead technical evaluations of RFQs and provide guidance on functionality, power, performance, and area tradeoffs.
• Partner with product marketing and key customers to define best-in-class technical solutions across product generations.
• Help define product and technology roadmaps based on customer needs, market direction, and technical trends.
• Translate standards, constraints, and ecosystem trends into architecture goals, requirements, and engineering priorities.
• Own the scoping, planning, and execution tracking of design activities and product releases.
• Guide architectural decisions with a focus on outcomes, scalability, product impact, and efficient implementation.
• Create clear documentation including functional specifications, architecture, microarchitecture, and product requirements.
• Develop, debug, and enhance RTL; run lint checks and perform simulation.
• Partner with verification to shape test plans, review results, and drive root-cause analysis and resolution of failures.
• Lead and contribute to design reviews to ensure technical rigor and design quality.
• Perform synthesis tasks including writing timing constraints, running logic synthesis, analyzing reports, achieving timing closure, and implementing ECOs.
• Identify risks, dependencies, and roadmap gaps early, and drive cross-team mitigation.
• Align engineering, product, and business teams on customer needs, differentiation, and execution.
• Communicate technical strategy, priorities, and rationale to internal and external stakeholders.

Qualifications

Basic Qualifications

10-12 + years of experience and a strong track record in the following areas:

• Bachelor's or master's degree in electrical engineering, computer engineering, or related field.
• Technical leadership with the ability to plan, manage, and influence engineering, product, and business stakeholders.
• Digital design including state machines, data paths, FIFOs, asynchronous crossings, clock and reset concepts, and high-speed, low-power design.
• Verilog/SystemVerilog and synthesizable design concepts targeting deep sub-micron technology nodes.
• Systems thinking to evaluate technical tradeoffs and translate them into product direction and prioritized requirements.
• Deep knowledge of networking protocols including 802.3 (Ethernet), PCIe, CXL, UCIe, UALink, and related standards.
• Experience with inter- and intra-chip buses and fabrics, including NoC, coherent/non-coherent fabrics, arbitration, flow control, and latency/bandwidth optimization.
• Comprehensive understanding of architectural impact on logic synthesis, timing closure, and physical implementation.
• Excellent communication skills for presenting complex concepts, driving alignment, and producing clear requirements and strategy documents.
• Unix/Linux scripting (Perl, Tcl, Python, and shell).
• Advanced debugging skills.
• Forward Error Correction (FEC) algorithm theory and basic data communication theory.
• Experience with Cadence, Mentor, and Synopsys tools for simulation, lint, and synthesis.

Preferred Qualifications

• AI infrastructure or AI workload knowledge
• UVM and constrained-random testing experience.
