About the role
- This is a unique opportunity to take ownership of critical opto-mechanical and electronic assembly processes that define the precision, yield, and quality of Voyant's LiDAR modules.
- Your work will directly impact Voyant products, accelerating time-to-market, reducing cost, and ensuring consistent product quality across global manufacturing sites.
Responsibilities
- Working through the design process mechanically, thermally and electrically to create the optimal solution while staying within supplier manufacturing capabilities.
- Creating CAD models for simulation and performing simulations to verify designs prior to release.
- Define and maintain process parameters for high-precision die-attach and placement equipment. Drive correlation between pick-and-place accuracy, epoxy flow, and bond-line thickness for consistent optical coupling.
- Establish and control parameters for automated dispense systems. Develop dispense recipes controlling needle diameter, pressure, time, temperature, and material conditioning. Characterize cure profiles and shrinkage impacts on optical alignment stability.
- Design and execute structured DOEs to characterize process sensitivity and optimize yield. Use statistical methods to quantify variability and identify dominant factors affecting alignment accuracy, void formation, or optical loss.
- Familiarity with microelectronics and photonics reliability and qualification standards such as Telecordia, JESD47 and AEC-Q. Also able to lead Root Cause Corrective Actions (RCCAs) with suppliers, Design and Process FMEA's and DOE planning.
- By leveraging cutting-edge silicon photonic chips smaller than your fingertip, we deliver sensors that are not only revolutionary in performance but also affordable enough to integrate into any system.
- As a Principal Silicon Photonic Packaging & Process Engineer, you will lead the development and scaling of precision opto-mechanical assembly processes.
- You will work closely with photonics, mechanical, and test teams to translate design concepts into R&D builds then into repeatable production processes.
- You will also partner with our contract manufacturers to qualify lines, improve yields, and drive continuous process improvements.
Requirements
- BS or MS in Mechanical, Manufacturing, Photonics, or Electrical Engineering (or equivalent experience)
- 10+ years hands-on experience in semiconductor, photonics packaging, or precision opto-mechanical assembly environments
- Strong understanding of adhesive dispense physics (viscosity, wetting, cure shrinkage) and related automation equipment
- Proficiency with DOE methods, SPC, and Minitab (or equivalent tools)
- Demonstrated experience working with automation solution providers and contract manufacturers to transfer and adapt prototype processes into high-volume production
- Deep familiarity with automated alignment and die-attach systems
- Excellent problem-solving skills and ability to collaborate across mechanical, optical, and test teams
- Willingness to travel up to 25% domestically and internationally
- Preferred Qualifications:
Nice to have
- Experience with automated micro-optics or fiber alignment processes
- Experience in standard optics alignment and assembly for lens-to-PIC coupling
- Familiarity with standard micro-electronic assembly (die attach, wire bond, hermetic lid seal, PCBA/SMT)
- Understanding of cleanroom protocols and ESD control best practices
- Familiarity with ISO 9001 process control or automotive-style production quality systems
- Understanding of photonic packaging materials (epoxies, UV adhesives, underfills) and their environmental stability
- Background in precision metrology systems (e.g., digital microscopes, interferometers, or confocal profilers)
- Experience with Finite Element Analysis for both mechanical and thermal simulations
