Job description

Mojo Vision is pioneering a highly flexible, wafers-in, wafers-out micro-LED platform to unlock AI applications in multiple market segments. Built over nine years by our skilled engineers, our system-level process combines advanced 300mm silicon architecture with GaN-on Silicon emitters, proprietary quantum dots, and micro-lens arrays to solve conventional trade-offs in size, brightness, bandwidth density, and power. Our scalable, manufacturing-ready approach enables breakthrough products such as AI glasses and next-generation optical interconnects.

At Mojo, our team includes talented professionals with expertise in product design, user experience, applied physics, hardware, software, optics, photonics, electronics, chemistry, and vision science.

We are a startup founded by technology experts with decades of experience developing pioneering products and platforms backed by some of the world's leading technology investors in Cupertino, CA.

Roles and Responsibilities

We are looking for an experienced analog layout contractor to join us full-time from May 2026. The perfect candidate will have extensive experience in analog layout in state-of-the-art FinFet nodes. This role requires deep hands-on layout expertise and a strong understanding of advanced node effects. Familiarity with SKILL coding is a plus. The candidate should have working knowledge of UNIX and be self-sufficient. Communication is key to success in this role.

• Design and implement complex layout for mixed signal and analog circuits in advanced FinFet technologies (e.g. 5nm, 3nm or similar).
• Own layout development in IP/block level, with awareness of chip-top integration constraints.
• Optimize layout for area, matching, parasitics, reliability and manufacturability.
• Work closely with circuit designers to co-optimize performance, area and robustness.
• Contribute to methodology improvements, including layout automation and SKILL-based flows.

Required Skills

• Proven experience in custom analog layout design in advanced FinFET nodes
• Strong understanding of layout dependent effects across technology nodes (e.g., LOD, WPE, stress effects) and advanced node constraints such as multi-patterning, fin quantization, and restrictive design rules.
• Must recognize failure prone circuit and layout structures, have experience with analog and DFM best practices, and proactively work with circuit designer for best approach to problems.
• Expertise in Cadence Virtuoso (Layout XL or equivalent) and Calibre (or equivalent) for physical verification.

Preferred Skills

• Excellent communication skills and ability to work independently in a fast-moving environment
• Experience with high speed I/Os, image sensors or pixel arrays
• High level of proficiency in interpretation of Calibre, LVS, DRC, ERC results. Proficiency in SKILL coding and layout automation
• Work across IP, chip-top and cross-layer integration (CMOS + GaN)

Hourly Rate: $100-115 based on experience
