Principal Optical Engine (OE) / Link Architect
Santa ClaraPosted Jul 30, 2026via greenhouse
Job Title: Principal Optical Engine (OE) / Link Architect
About the Role
We are seeking a highly experienced and visionary Principal Optical Engine (OE) Architect to lead the technical definition and architectural of Optical link design of our next-generation optical products. In this critical role, you will be responsible for defining an OCI-MSA (Optical Compute Interconnect - Multi-Source Agreement) ready Optical Engine
Working in lockstep with Product Management, you will take the Market Requirements Document (MRD) and translate those market needs into a highly detailed, actionable Product Requirements Document (PRD). You will leverage your deep expertise in end-to-end optical link architecture, Photonic Integrated Circuits (PIC), and Electronic Integrated Circuits (EIC) to architect solutions that push the boundaries of high-speed optical interconnects.
Key Responsibilities
• PRD Generation & Ownership: Collaborate directly with Product Management (who drives the MRD) to develop, refine, and own the comprehensive Product Requirements Document (PRD) for our next-generation Optical Engines.
• Transceiver System Architecture: Architect complete optical transceiver sub-systems. Balance optical, electrical, thermal, and mechanical parameters to meet stringent power, performance, and cost targets for OCI-MSA compliance.
• End-to-End Link Architecture: Define and manage the end-to-end optical link budget. Model optical impairments (e.g., dispersion, noise, crosstalk, penalties), define Forward Error Correction (FEC) requirements, and ensure robust signal integrity across the link.
• PIC & EIC Integration: Lead the system-level architecture bridging Photonic Integrated Circuits (PIC) and Electronic Integrated Circuits (EIC), heavily optimizing the interaction between DSPs, TIAs, Modulator Drivers, and optical components.
• Modulation & Signal Integrity: Drive architectural decisions regarding high-speed modulation formats (e.g., PAM4, Coherent) and collaborate with SI/PI teams to ensure the electrical interfaces meet high-speed compliance standards.
• Standards & Ecosystem Leadership: Ensure product alignment with current and emerging OCI and MSA standards. Act as a technical representative for the company within relevant industry consortia.
• Trade-off Analysis: Conduct rigorous technical and cost trade-off analyses for different OE architectures, packaging technologies, component selections, and link budget allocations.
Required Qualifications & Experience
• Experience: 10+ years of proven industry experience functioning as a Transceiver Architect, Link Architect, or Principal Optical System Architect.
• Industry Pedigree: Previous experience at tier-1 semiconductor or optical networking companies is highly preferred (e.g., Intel, Broadcom, Marvell, Cisco, or similar industry leaders).
• Core Domain Expertise: Deep, hands-on architectural knowledge of both PIC (Photonic Integrated Circuits) and EIC (Electronic Integrated Circuits).
• Proven track record in optical transceiver design (e.g., OSFP, QSFP-DD, or Co-Packaged Optics).
• Mastery of link budgeting, optical penalty modeling, and FEC trade-offs for high-speed datacom/telecom links.
• Standards Knowledge: Familiarity with the Optical Compute Interconnect (OCI) ecosystem and experience developing products aligned with Multi-Source Agreements (MSAs).
• Product Definition Skills: Demonstrated capability to write highly detailed PRDs and translate high-level market requirements (MRDs) into strict, actionable technical specifications for engineering teams.
• Education: MS or Ph.D. in Electrical Engineering, Photonics, Physics, or a related field.
Preferred Skills
• Experience with advanced 2.5D/3D packaging technologies (e.g., TSV, micro-bumping, flip-chip) relevant to modern Optical Engines.
• Strong understanding of thermal challenges in high-density, co-packaged, or pluggable optical interconnects.
• Excellent communication skills with the ability to articulate complex link-level technical concepts to cross-functional engineering teams and business stakeholders.
