hirify.global builds high-speed connectivity infrastructure and networking technologies for the AI era.

What you will do

• Own the technical design of heterogeneously integrated optical modulator PICs for current and future coherent products.
• Design or guide passive routing, couplers, splitters, polarization elements, monitors, crossings, and other PIC functions.
• Use measurement data to refine RF, optical, and electro-optic models and close the loop between simulation, layout, fabrication, and performance.
• Lead technical decisions, trade-off analysis, design reviews, and design direction for modulators and PICs.
• Collaborate across teams on system constraints, reliability, multi-chip integration, packaging, and thermal requirements.
• Contribute to non-modulator PIC projects requiring deep device-design expertise as project needs evolve.

Requirements

• Expertise in electro-optic modulator physics, RF/optical co-design, traveling-wave electrodes, velocity and impedance matching, bandwidth optimization, and high-speed measurement.
• Strong capability with EM and circuit simulation tools such as HFSS and/or ADS.
• Strong capability with optical modeling methods including FDTD, EME, and eigenmode solvers.
• Ability to build and calibrate compact models from simulation and measurement data.
• Working knowledge of PIC materials, foundry processes, PDKs, layout rules, process monitors, and design-for-test and manufacturing practices.
• Ph.D. in electrical engineering, engineering physics, applied physics, photonics, or a related field, plus five or more years of relevant industry experience.

Nice to have

• Experience with high-speed electro-optic modulators, thin-film lithium niobate, silicon photonics, heterogeneous integration, or related PIC technologies.
• Experience providing project leadership and technical reporting while maintaining hands-on design involvement.

Culture & Benefits

• Flexible remote work environment focused on innovation, integrity, collaboration, and professional growth.
• Medical, dental, and vision plans.
• 401(k) with company matching in the United States.
• Employee Stock Purchase Program, Employee Assistance Program, paid holidays, paid sick leave, and vacation time.
• Paid family leave and other applicable leave programs.
