About Quintessent

The resurgence of chip investments has driven an upward inflection in the performance of individual compute chips, but the ability of those chips to communicate with one-another has not kept pace. Communication, not computation, is now the system level bottleneck in large-scale computing and AI applications.

Quintessent is developing connectivity solutions to break the chip communication bottleneck and future-proof compute scaling.

About the role

• We are looking for a senior, hands-on laser expert to take technical ownership of our high-power laser and amplifier designs and drive them from advanced prototypes into production.

What you'll do

You will be the technical authority for critical laser devices, responsible for:

• Driving designs from concept → prototype → product → production
• Architecture, design, performance modeling, and data analysis of high-power quantum dot lasers and amplifiers
• Making key decisions to optimize product performance, yield, reliability, and scalability
• Working side-by-side with fabrication, test, and reliability teams to achieve goals
• Helping define the next-generation roadmap for Quintessent’s laser platforms

Your work will directly shape the products that ship and the capabilities the company builds.

Qualifications

To succeed, you will need these qualifications:

• PhD in Physics, Applied Physics, EE, or similar, plus 5+ years of industry experience
• Deep experience designing high-power (200-400 mW+) III-V semiconductor lasers
• Hands-on experience across design, simulation, fabrication, test, and failure analysis
• Strong command of simulation tools and methods (FMM, FDTD, TDTW, etc.)
• Experience taking devices from prototypes to real products

Bonus if you’ve also:

• Supported high-volume production
• Done electrical and thermal simulation
• Worked directly with customers or partners
