Semiconductor Laser Design Engineer
Confirmed on the employer's own hiring board on Oct 25, 2026. First seen by Alion on May 5, 2026. Ayo Semiconductor scores B on the Alion truth index.
Ayo is a venture-backed early-stage startup that will radically re-define how humanity performs compute for AI. Our photonic processors will provide orders of magnitude improvement in speed and power efficiency in comparison to conventional digital compute platforms by taking advantage of the natural parallelism, speed and energy efficiency of light.
We are seeking a semiconductor laser engineer to serve as a core team member who will be among the first employees of the company. The engineer will drive the optimization of both active III-V epitaxy and active device design (on-chip lasers and SOAs). The ideal candidate has taped out or fabricated working semiconductor laser or SOA devices, has a deep understanding of the underlying physics, and has a desire to explore the limits of what can be built with current fabrication technologies. This will be a key role within the photonics team, requiring close collaboration with other team members and engineering functions.
Responsibilities:
Simulate/design III-V epitaxies optimized for our application
Design test structures for measurement of electronic and optical properties of fabricated epitaxial wafers
Design, tape out and test integrated lasers and SOAs
Work with systems, electronic, and AI teams to design prototype chips
Mentor & guide junior photonics engineers and photonics test engineers
Qualifications:
PhD or MS with 5+ years experience
Experience designing, taping out or fabricating, and testing integrated semiconductor lasers, LEDs and/or SOAs
Experience using commercial simulation tools (such as Ansys/Lumerical, Tidy3D, PhotonDesign or similar)
Proficiency with Python
Preferred Qualifications:
Experience designing multi-quantum well and/or quantum dot structures
Experience designing and laying out photonic integrated circuits
Experience probing/testing photonic integrated circuits
Experience with advanced packaging of photonic integrated circuits such as hybrid or flip-chip integration
