Job Summary
About the Team
Infleqtion is commercializing quantum technology building deployable systems where photonics is the engine for performance scale and reliability. Our photonics team develops photonic integrated circuits (PICs) and related optical subsystems that enable chip-scale laser sources modulation routing and control for next-generation quantum products. We work closely with quantum system teams and external foundry/assembly partners to turn ambitious optical performance targets into manufacturable hardware.
About the Role
Infleqtion is seeking a Senior Laser & Nonlinear Photonics Engineer to lead and execute system-level photonics experiments with a focus on laser sources and/or nonlinear optics modules (e.g. frequency conversion parametric processes comb generation) and their integration into larger photonic and quantum subsystems.
In this role you will take end-to-end ownership of experimental development: architecture trades optical design hands-on build stabilization/control measurement automation performance characterization and iteration toward reliable prototypes.
We are looking for a highly motivated individual who thrives in ambiguity enjoys working in a small dynamic team environment and has a passion for solving challenging problems that lead to high-impact technological advances.
How you will drive impact
- Architect build and validate laser and nonlinear photonics subsystems that meet demanding specs (linewidth frequency noise RIN power stability efficiency SWaP reliability).
- Develop and run system-level experiments: optical bench builds fiber-based architectures free-space coupling high-speed modulation and precision frequency control.
- Implement stabilization and control: frequency locks servo design modulation/demodulation schemes and long-term drift mitigation.
- Create robust measurement pipelines (automation calibration data analysis) to accelerate iteration and improve reproducibility.
- Translate experimental learnings into engineering requirements for packaging manufacturability and productization; collaborate closely with PIC designers electronics packaging and manufacturing partners.
Requirements
- M.S. or Ph.D. in Electrical Engineering Optical Engineering or a related field (or equivalent practical experience).
- 5 years of hands-on experience building and characterizing laser systems and/or nonlinear photonics experiments with demonstrated outcomes (prototypes delivered performance records or deployed systems).
- Deep practical experience with optical instrumentation and lab execution (OSA ESA RF sources high-speed photodiodes wavemeters interferometers power meters polarization control low-noise detection).
- Experience measuring and improving laser performance metrics (e.g. linewidth estimation frequency noise/phase noise RIN drift mode hops) and diagnosing failure modes.
- Comfort designing experiments that mix optics RF controls (AOM/EOM modulation photodetection servo loops timing/synchronization).
- Strong documentation and communication skills; ability to drive cross-functional alignment and make clear technical tradeoffs.
We Highly Value:
- Nonlinear optics/photonics experience in one or more of: SHG/SFG/DFG OPO/OPG PPLN/PPLT (bulk or waveguide) microresonator/Kerr combs supercontinuum or parametric amplification.
- Experience with narrow-linewidth diode lasers fiber lasers solid-state lasers external-cavity designs and/or integrated/hybrid laser architectures.
- Familiarity with photonic integration constraints and how system requirements map into PIC designs (thermal sensitivity coupling losses reflections backscatter isolation).
- Experience transitioning lab builds toward ruggedized/packaged systems (alignment tolerancing thermal design vibration sensitivity reliability test plans).
- Scientific programming for automation/analysis (Python LabVIEW) and version control best practices.
- Optional if relevant Experience in atomic/quantum physics experiments (laser cooling spectroscopy frequency references) or similar precision photonics domains.
