Job summary

Pulse Space Inc. is seeking a Senior Laser Engineer to design, build, characterize, and optimize high‑power fiber laser systems from hundreds of watts to multi‑kilowatt outputs. You will work across optics, mechanics, electronics, and software teams to move concepts from prototype to production‑ready hardware.

You will lead alignment, splicing, and testing, while optimizing performance and reliability. This role combines hands‑on lab work with analytical modeling in a cutting‑edge photonics

Qualifications

• B.S. or higher in Physics, Optical Engineering, Electrical Engineering, or a closely related discipline.
• 5+ years hands‑on experience designing, building, and testing high‑power fiber laser systems (>100 W output).
• Deep understanding of laser physics: gain media, resonator design, mode theory, Gaussian beam propagation, and fiber nonlinear optics.
• Direct experience with Yb‑doped double‑clad fiber lasers and amplifiers, including pump absorption optimization, ASE management, and thermal load budgeting.
• Proficiency in fiber preparation and splicing (fusion splicer operation, cleaving, stripping, and recoating).
• Working knowledge of laser safety standards and cleanroom / optical‑lab protocols.
• Familiarity with optical design and simulation tools (e.g., Zemax, FRED, etc.)
• Strong analytical skills with demonstrated experience in data acquisition, statistical analysis, and technical reporting.

Responsibilities

• Design and develop high-power CW fiber laser systems based on Yb-doped and other rare-earth-doped fibers using MOPA architectures.
• Perform precision optical alignment, fusion splicing, and assembly of fiber laser cavities, amplifier stages, and beam delivery optics.
• Characterize laser performance: output power, beam quality (M²), spectral linewidth, temporal stability, noise (RIN/PSD), and wall-plug efficiency.
• Debug and troubleshoot high-power laser subsystems from first light through qualification, identifying root causes under schedule pressure.
• Diagnose and mitigate nonlinear effects — SBS, SRS, TMI, and photodarkening — to maximize output power and reliability.
• Develop and maintain test procedures, acceptance criteria, and technical documentation for subsystems and integrated laser products.
• Analyze experimental data using Python, MATLAB, or equivalent tools; build simulation models to guide design decisions and predict system performance.
• Collaborate with cross-functional teams on thermal management, optomechanical packaging, control electronics, and system-level integration.
