Position Summary

We are seeking a Senior or Principal Laser Module Tech Lead to lead the system architecture, integration, and technical execution of advanced laser modules for high-speed optical communication applications. This role will own the end-to-end performance of the laser module, ensuring seamless integration of semiconductor lasers, SOAs, silicon photonic PICs, optical packaging, electronics, firmware, and thermal management into a reliable, manufacturable product.

As the technical lead, you will work across engineering disciplines and with external suppliers to deliver laser modules from concept through production.

Key Responsibilities

• Own the overall architecture and system performance of laser module products.
• Define module-level requirements, interface specifications, and performance budgets.
• Allocate optical, electrical, thermal, and mechanical performance targets across subsystem owners.
• Lead integration of:
• Semiconductor lasers (DFB, DBR, ECL, tunable)
• SOAs
• Silicon photonic PICs
• Optical isolators, filters, and fiber interfaces
• Driver electronics and control circuitry
• Firmware for laser monitoring and control
• Mechanical packaging and thermal solutions
• Define characterization plans for optical power, wavelength, linewidth, SMSR, RIN, polarization, coupling efficiency, and thermal performance.
• Lead system-level debugging and root-cause analysis of optical, electrical, and thermal issues.
• Drive design tradeoffs balancing performance, manufacturability, reliability, and cost.
• Work closely with laser, PIC, firmware, electrical, mechanical, and manufacturing teams to achieve system performance goals.
• Collaborate with external suppliers on component specifications, qualification, and manufacturing readiness.
• Support product qualification, reliability testing, and transfer to volume manufacturing.
