Lead the architecture and provide guidance for technical execution of photonic integrated circuit (PIC) and electronic integrated circuit (EIC) platforms, delivering pilot projects that prove technology feasibility, system value, manufacturability, and a path to productization.

Job Summary

• Own end-to-end architecture for silicon photonics solutions that combine PICs, EICs, advanced packaging, optical interfaces, firmware, and system-level control.
• Translate product, customer, and business requirements into system architecture, technical specifications, performance budgets, interfaces, technology choices, and executable pilot plans.
• Define and deliver pilot demonstrators that de-risk critical capabilities such as optical I/O, co-packaged optics, chiplet connectivity, sensing, or other strategic silicon-photonics use cases.
• Provide technical leadership across concept, modeling, design, tape-out, packaging, bring-up, characterization, and proof-of-value demonstrations.
• Build a pragmatic roadmap from prototype to scalable products, including platform reuse, ecosystem choices, and make/buy/partner recommendations
• Define system requirements and partition functionality across PIC, EIC, package, substrate/interposer, optics, firmware, and host interfaces
• Create link and system budgets covering optical loss, laser power, modulation, receiver sensitivity, signal integrity, power, thermal behavior, latency, reliability, and testability
• Guide PIC architecture and design tradeoffs involving modulators, photodetectors, waveguides, couplers, filters, splitters, monitors, and calibration structures
• Guide EIC architecture and tradeoffs involving laser/modulator drivers, TIAs, clocking/CDR, SerDes interfaces, ADC/DAC or control loops, telemetry, power management, and digital control
• Lead architecture reviews and design reviews; establish interface specifications, verification plans, risk registers, success criteria, and measurable pilot exit gates.
• Coordinate foundries, OSAT/advanced-packaging partners, IP vendors, EDA/tool providers, laboratories, and university or ecosystem collaborators
• Partner with product, software, design, verification, packaging, test, reliability, manufacturing, and business teams to achieve performance, cost, schedule, and quality objectives
• Mentor architects and engineers, raise technical capability across the organization, and communicate recommendations clearly to senior technical and business leaders.

Contribute to invention disclosures, patents, technical publications, supplier assessments, and longer-term silicon-photonics technology strategy

• BTech/BE, MTech/ME, or PhD in Electrical Engineering, Electronics, Photonics, Applied Physics, Computer Engineering, or a related field with hardware engineering experience of 15+ years
