Analog & Mixed Signal Engineer

Sphere Semi is a new type of semiconductor company, where an AI model designs chips alongside humans. Our AI chip design algorithm allows us to produce customized and optimized designs at scale.

We are seeking an Analog & Mixed Signal Engineer to help ensure the success of our designs, from concept through to production, with a focus on thorough verification and design integration.

Key Responsibilities:

• Define the design and verification process: You will be responsible for ensuring that our approach produces functional chips with a minimal number of tape-outs. In some cases, we are exploring what it will take to achieve first-pass success.
• Define critical design parameters: Establish key design variables, constraints, and test benches that will guide our AI-driven design automation system. Your goal will be to ensure that the system generates meaningful, manufacturable results, while filtering outputs through human review as needed.
• Oversee integration of digital components: As our chip designs may include a mix of analog and digital elements, you will be responsible for ensuring the smooth integration of these components into full chip designs.
• Adapt to and implement new tools: You will be familiar with standard EDA analog and RF toolsets (Cadence, Keysight, etc.), but also be expected to adapt to and work with new and evolving internal tools and frameworks.
• Cross-functional collaboration: Partner with AI engineers, software developers, and chip designers to ensure our automated tools produce optimized designs that can be efficiently taped out. You’ll also work closely with customers and adapt to various process technologies and project needs.
• Hands-on design & verification: In the early stages, you may directly create and validate designs, or set up new design flows. You’ll actively participate in hands-on engineering tasks, ensuring designs are verified before production.

Qualifications:

• Ph.D. or Master’s in Electrical Engineering, with a focus on analog/mixed-signal/RFIC design, or equivalent industry experience.
• Flexibility in experience level: Recent Ph.D. graduates with strong foundational skills and adaptability, or experienced industry veterans with a proven track record, are encouraged to apply.
• Track record of successful tape-outs: Demonstrated experience participating in design teams or projects that resulted in functional analog/RFIC chips in production.
• Experience with digital integration: Familiarity with mixed signal chips that involve close integration between digital and analog components.
• Tool flexibility: Strong knowledge of industry-standard tools, with the ability to adapt to new methodologies and tools beyond traditional EDA.
