Principal Analog Design Engineer

About Neurophos

The demand for new data centers and AI compute is rapidly outpacing the planet's energy capacity. Digital solutions are hitting a power wall as we approach the physical limits of traditional silicon. Conquering this bottleneck means rethinking the fundamental architecture of inference compute. The industry's current path can't meet the need, so we're taking a different approach.

Instead of traditional electronic circuits, we use silicon photonics and an active, programmable metasurface to perform matrix multiplications at the speed of light. Our optical cells are 10,000x smaller than traditional photonic components, enabling unprecedented density. By using photonics instead of electricity, our chips become more efficient as they scale. This architecture will deliver up to 100 times the energy efficiency of existing solutions while significantly improving performance for large-scale AI inference.

We've assembled a world-class team of industry veterans and recently raised a $110M Series A led by Gates Frontier. Participants include M12 (Microsoft's Venture Fund), Carbon Direct Capital, Aramco Ventures, Bosch Ventures, Tectonic Ventures, Space Capital, and others.

Position Overview:

We are seeking a seasoned Principal Analog Design Engineer to play a vital role in developing cutting-edge full-custom electronic transceiver components that interface directly with our custom silicon photonics and are essential to our revolutionary photonic AI platform. You will own the full lifecycle of analog blocks, from specification and architecture to tape-out-ready layout. Success in this role requires a deep understanding of transistor-level circuit design, linearity, noise performance, and signal integrity in CMOS processes up to GHz speeds. If you possess a proven track record of designing robust, ultra-fast analog circuits and are eager to work at the intersection of electronics and photonics, you will make a defining impact on the future of optical computing.

Location: Austin, TX, Sunnyvale, CA, or Hsinchu, Taiwan. Full-time on-site position.

Key Responsibilities:

• Design, simulate, and verify high-speed analog circuits, including high-swing drivers, transimpedance amplifiers, ADCs, DACs, and PLLs, in deep-submicron CMOS technologies.

• Define block architecture and specifications based on system-level requirements.

• Perform full-custom schematic capture, advanced analog simulations, and complete physical layout, including DRC/LVS, of critical analog blocks using Cadence Virtuoso.

• Ensure rigorous signal integrity and power integrity across all high-speed interconnects.

• Conduct layout floor planning.

• Conduct post-layout extraction and simulation to validate performance against parasitic effects.

• Collaborate closely with the Photonics and Digital teams to optimize the electro-optic interface and maximize cross-disciplinary performance.

• Collaborate with team members to prepare and conduct the bench characterization and production tests.

Qualifications:

• MS or PhD in Electrical Engineering.

• 10+ years of professional experience in full-custom analog integrated circuit design, 5+ years of dedicated experience in either GHz-speed RF or GHz-speed broadband analog design.

• Demonstrated expert proficiency in the Cadence tool suite, specifically Virtuoso schematic, simulation, and custom layout.

• Deep understanding of semiconductor device physics, linearity, noise analysis, and high-frequency circuit theory.

• Proven track record of taking high-speed analog blocks from concept to mass production (successful tape-outs).

Preferred Skills:

• A background in photonic transceivers or optical communication electronics.

• Extensive design experience in TSMC latest technology nodes, such as N5P, N3P, and N2P.

• Experience designing high-speed data converters.

• Experience designing low-jitter clocking circuits, including PLLs.

• Proficiency in electromagnetic simulation tools such as EMX or HFSS.

• Experience with frequency domain simulation in Spectre RF.
