We value collaboration, curiosity, and diverse perspectives, and give every team member the opportunity to make an immediate impact while growing their skills. Location Onsite at our Pleasanton, CA office; travel up to 5%. The Role As a PIC Laser Scientist, you will bridge the gap between fundamental optical physics and scalable chip‑scale technology, leading the end‑to‑end development of custom laser systems from conceptual design through system‑level integration. Your work will focus on architecting the transition of high‑precision frequency combs and ultra‑low‑noise systems from traditional discrete components to advanced Photonic Integrated Circuit (PIC) platforms, driving innovation for quantum timing, atomic clocks, and inertial sensors. Responsibilities System Architecture: Develop custom laser systems from fiber‑based oscillators to integrated chip‑scale architectures. PIC Design & Simulation: Design and simulate PIC layouts optimized for high‑Q micro‑resonators and dispersion‑engineered nonlinear optics using materials such as SiN, TFLN, and Tantala. Translation & Integration: Architect the migration of frequency combs and low‑noise systems from discrete fiber/free‑space components to PIC platforms. Assembly & Characterization: Build and characterize conventional systems, including fiber spooling, MOPA configurations, and discrete nonlinear conversion stages. Precision Metrology: Perform rigorous characterization of frequency noise, phase noise, and Allan deviation at both benchtop and chip levels. Frequency Stabilization: Develop testing protocols for stabilization architectures, including PDH locking and f‑2f self‑referencing. Cross‑Functional Collaboration: Partner with hardware teams to integrate laser systems into atomic clocks and quantum timing sensors. Requirements 3+ years of professional experience working with ultra‑stable cavities, frequency combs, or atomic clocks. PhD in Physics, Electrical Engineering, or a related field focused on atomic/optical physics, frequency metrology, or integrated photonics. U.S. citizenship, lawful permanent residency, or qualifying refugee/asylee status (required for export‑control compliance). Hands‑on experience measuring RIN, frequency noise, and phase noise using phase‑noise analyzers and high‑speed RF equipment. Experience with nonlinear optics (supercontinuum generation or SHG in bulk crystals, nonlinear fibers, or integrated waveguides). Proficiency in fiber fusion splicing (PM/specialty), fiber spooling, and high‑tolerance free‑space assembly. Preferred Qualifications Simulation expertise in Lumerical (FDTD/MODE) or COMSOL for designing waveguides and resonators. Deep understanding of mode‑locked lasers and fceo detection and stabilization. Practical experience with chip‑level probing and coupling to SiN, thin‑film lithium niobate, or tantala waveguides. Strong knowledge of PID control loops, high‑bandwidth feedback, and low‑noise frequency/power controllers. Python or MATLAB proficiency for automating optical characterization and processing high‑bandwidth noise data. Optical packaging experience with high‑efficiency laser‑to‑chip integration and coupling techniques. Benefits Platinum‑level family health coverage (medical, dental, vision). Health and dependent care Flexible Spending Accounts. Employer 401(k) contributions. 20 days of paid time off & 11 paid holidays. Paid parental leave. Fully stocked kitchen. Approximate base salary range: $163,430 to $213,972 per year, inclusive of base, bonus, equity, and benefits. US Technical Jobs: This position requires you to be a U.S. Person for export‑control compliance. Employment is contingent on verifying your status as a U.S. citizen, national, permanent resident, or qualifying refugee/asylee. Additional questions will be asked regarding your immigration status to ensure compliance with federal law.
