Job summary

Olix Computing in Austin, TX is seeking a Senior/Staff Analog Design Engineer to help develop high-speed SerDes and mixed-signal subsystems for a next-gen SoC. Role spans from circuit implementation to post-silicon validation, collaborating with teams locally and in London/Bristol.

The candidate should have 10+ years in analog/mixed-signal IC design, with hands-on SerDes experience at 25 Gbps+. Strong signaling fundamentals and FinFET knowledge are essential.

Qualifications

• MS or PhD in Electrical Engineering with 10+ years of analog/mixed-signal IC design experience.
• Strong analog mixed-signal design background with hands-on SerDes experience at data rates of 25 Gbps or higher.
• Solid understanding of high-speed signaling concepts: jitter, noise, equalization, SI, and link budgeting.
• Expertise in advanced FinFET nodes with device physics, parasitics, and layout sensitivity.
• Proficiency with Cadence Virtuoso, Spectre, and flows including PVT, Monte Carlo, EM-IR, reliability analysis.
• Experience developing behavioral and Verilog-A models for mixed-signal verification.
• Familiarity with post-silicon bring-up, lab measurement equipment, and correlating data to simulations.
• Strong communication skills and ability to collaborate across analog, digital, optical, and system teams.

Responsibilities

• Architect and design high-speed SerDes blocks from spec to silicon in advanced nodes.
• Perform schematic and post-layout simulations to ensure robust margins and reviews.
• Run EM simulations for passives, interconnects, and on-die routing.
• Develop behavioral/Verilog-A models for system-level verification.
• Supervise mask designers and provide floorplan/layout guidelines.
• Collaborate with optical, digital, and system teams on interfaces and link performance.
• Support post-silicon bring-up, lab validation, and debugging.

Job description

AI is growing faster than any technology in history and the explosion in demand has created a massive infrastructure gap; we can no longer build chips or power stations fast enough to keep up. The industry is still leaning on a ten-year-old hardware blueprint that has reached its limit. A new paradigm that is faster and more efficient will be the biggest economic opportunity of the next century and create the most important company of the next decade. The OLIX Decode Accelerator 1 (DX-1) is the first accelerator architected specifically for decode. Rack-scale co-design of logic, data movement, packaging, optics and interconnect enables a step change in system level performance.

The Role

We are seeking highly skilled and motivated Senior/Staff Analog Design Engineer to contribute to the development of high-speed SerDes and mixed-signal subsystems for a next-generation SoC. This role spans the full design lifecycle, from circuit implementation through post-silicon validation, across serializers, clock generation, equalization, and supporting analog blocks, requiring strong hands-on circuit design skills and a solid grasp of high-speed signaling fundamentals.

This is a highly collaborative, in-office role based in Austin, TX, working closely with cross-functional teams locally while also partnering with engineers in our London and Bristol offices to drive coordinated, global execution.

Responsibilities

• Architect and design high-speed SerDes blocks (serializers, TX drivers, TIAs, CTLEs, CDRs, deserializers, and clock generation) from specification through silicon in advanced FinFET nodes.
• Perform schematic and post-layout simulations (including EM-IR and reliability simulations) to ensure robust silicon margins, and own design reviews and documentation.
• Run EM simulations for passives, package interconnects, and on-die routing.
• Develop behavioral and Verilog-A models to enable system-level and mixed-signal verification.
• Supervise mask designers closely and provide floorplan and layout guidelines.
• Collaborate with optical, digital, and system teams on interfaces and link-level performance.
• Support post-silicon bring-up, lab validation, and debug.

Skills & Experience

• MS or PhD in Electrical Engineering with 10+ years of analog/mixed-signal IC design experience.
• Strong analog mixed-signal design background with hands-on SerDes experience at data rates of 25 Gbps or higher.
• Solid understanding of high-speed signaling concepts: jitter, noise, equalization, signal integrity, and link budgeting.
• Expertise in advanced FinFET nodes with solid grasp of device physics, parasitics, and layout-sensitive design.
• Proficiency with Cadence Virtuoso, Spectre, and industry-standard simulation flows including PVT, Monte Carlo, EM-IR, and reliability analysis.
• Experience developing behavioral and Verilog-A models for mixed-signal verification.
• Familiarity with post-silicon bring-up, lab measurement equipment, and correlating measured data to simulation.
• Strong communication skills and ability to collaborate across analog, digital, optical, and system teams.

Compensation & Equity

• Competitive Salary: Commensurate with your experience, skills, and location
• Equity & Ownership: Meaningful stock options. You’re not just joining the mission; you’re owning a piece of it
• Proximity Bonus: We value your time. To minimise your commute and maximise your life, we offer an annual Living-Local Bonus if your residence is within 20 minutes of the office
• Retirement Benefits: Employer-contributed retirement plans to help you build long-term financial security.
