About the Job

Requirements

  • A bachelor's degree in Physics, Optical Engineering, Electrical Engineering, or a related technical discipline is required.
  • At least 3 years of hands-on experience designing, building, and testing high-power fiber lasers or amplifiers is required.
  • Expertise in fiber laser and amplifier design, including rate-equation modeling and laser physics, is required.
  • Knowledge of high-power fiber laser physics, including thermal effects, photodarkening, nonlinear effects (SBS, SRS, SPM), transverse mode instability (TMI), and mitigation methods, is required.
  • Experience designing and selecting components for kW-class fiber lasers, including large-mode-area fibers, pump combiners, and cladding light strippers, is required.
  • Hands-on fusion splicing of large-mode-area and specialty fibers, and assembly and testing of high-power fiber lasers, is required.
  • Experience characterizing beam quality, spectrum, and power using M² measurements, optical spectrum analyzers, power meters, and beam profilers is required.
  • Working knowledge of Class 4 laser safety practices is required.
  • Applicants must provide proof of eligibility to work in the United States.
  • Applicants must be U.S. citizens, lawful permanent residents, protected individuals as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain required U.S. Department of State authorizations to comply with U.S. space technology export regulations, including ITAR.

Responsibilities

  • Design and develop high-power, near-diffraction-limited fiber laser sources and amplifiers for space-to-space laser power beaming.
  • Define laser architecture and requirements with the senior laser engineer, including wavelength, output power, beam quality, linewidth, polarization, wall-plug and optical efficiency, thermal load, and reliability.
  • Model laser and amplifier performance, including rate-equation gain and amplified spontaneous emission (ASE), thermal effects, nonlinear thresholds (SBS, SRS, SPM), and transverse mode instability (TMI).
  • Design and select components for high-power fiber lasers, including gain and delivery fibers, pump diodes, pump/signal combiners, cladding light strippers, isolators, end caps, and wavelength combiners.
  • Design, assemble, splice, and test high-power fiber lasers, and establish characterization of power, spectrum, M², polarization, and stability.
  • Develop non-standard sources as needed, such as thulium-doped fiber lasers near 0.8 µm, Raman fiber lasers, and frequency-doubled visible sources.
  • Work with Electrical Engineering, thermal, and beam-expander teams on diode drivers, heat rejection in vacuum, output collimation, and beam delivery.
  • Support space qualification, including radiation-induced attenuation and photodarkening, thermal-vacuum and vibration performance, outgassing, and pump-diode reliability and derating.
  • Support technicians in laser build practices and manage technical relationships with fiber, diode, and component vendors.

Desired Qualifications

  • Candidates with more than 3 years of relevant experience are preferred.
  • Design or qualification experience with space-qualified lasers or amplifiers is strongly preferred.
  • Experience with thulium, Raman, or frequency-doubled fiber sources is preferred.
  • Experience with spectral or coherent beam combining, or narrow-linewidth amplifiers, is preferred.
  • Experience with diode reliability, derating, and wavelength stabilization is preferred.
  • Experience using RP Fiber Power or equivalent commercial or custom fiber laser models is preferred.
  • A master's degree or Ph.D. in Physics, Optics, or Laser Engineering is preferred.

About the Company

Star Catcher

Provides space-based power via on-orbit energy grid

Star Catcher Industries is building an on-orbit energy grid called the Star Catcher Network, a constellation of Power Node satellites that harvest solar energy and beam it to customer spacecraft. It provides power on-demand to LEO satellites, enabling tasks like remote sensing, on-orbit processing, and telecommunications, without needing larger onboard solar arrays. The system uses a power-as-a-service model—Star Catcher owns and operates the energy infrastructure and sells electricity to customers as a service, with compatibility that works with existing solar arrays and no retrofitting. Its aim is to remove power constraints for LEO satellites and deploy a scalable energy grid, backed by seed funding and planned on-orbit demonstrations.
