Mask Designer Jobs in Austin, TX (NOW HIRING)

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.

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.

• 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.

• 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.

• 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.

Due to U.S. export control regulations, candidates’ eligibility to work at OLIX depends on their most recent citizenship or permanent residency status. We are generally unable to consider applicants whose most recent citizenship or permanent residence is in certain restricted countries (currently including Iran, North Korea, Syria, Cuba, Russia, Belarus, China, Hong Kong, Macau, and Venezuela). Applicants who have subsequently obtained citizenship or permanent residency in another country not subject to these restrictions may still be eligible.
