Senior Mixed Signal Engineer

Job Title

Senior Mixed Signal Engineer

Role Summary

Senior individual contributor and technical leader on SECQAI's SoC hardware team, responsible for mixed-signal and high-speed interface circuit design through silicon bring-up. The role collaborates with cross-disciplinary teams to integrate third-party IP, support verification and production, and contribute to roadmap and architecture decisions.

Experience Level

Senior — typically 9+ years of relevant mixed-signal/SoC design and implementation experience in advanced technology nodes.

Responsibilities

The core responsibilities focus on mixed-signal SoC circuit design, integration, verification, and production support.

• Architect, design, and integrate high-speed interfaces and analog mixed-signal circuits for next-generation SoCs.
• Define circuit requirements and drive designs from schematic through layout, verification, characterization, and tape‑out readiness.
• Collaborate with third-party IP providers to integrate and validate external blocks.
• Work with software, CPU, verification, security, and R&D teams to optimize system-level performance and interfaces.
• Support post-silicon verification, bring-up, debugging, and production support with product test teams.
• Contribute to design reviews, roadmap planning, and technical documentation; review peers' documentation and designs.
• Occasional travel to meet customers and partners as required for integration and validation.

Requirements

Must-have technical skills and experience; desirable items listed separately.

• 9+ years of relevant mixed-signal architecture, design and implementation experience in advanced nodes.
• Proven experience leading engineering teams and driving technical delivery.
• Expert understanding of signal integrity, mixed-signal design, and advanced-node analog/digital interfaces.
• Proficient with industry-standard EDA and analysis tools across the design flow (examples: MATLAB, Cadence, Synopsys, OpenROAD or equivalent).
• Hands-on experience across schematic capture, layout coordination, verification flows, characterization, and silicon bring-up.
• Strong collaboration skills for working across hardware, software, verification, and security teams.
• High standards for design quality, documentation, and reproducible engineering processes.

Nice-to-have:

• Experience with RISC-V and CHERI ISAs.
• Experience collaborating on integrated photonics designs.
• Knowledge of functional safety and security engineering practices and standards.
• Multiple designs taken from concept through tape-out.

Education Requirements

B.Eng., M.Eng., or Ph.D. in Electrical Engineering, Computer Science, or a related technical field — or equivalent industry experience.
