Position Overview:

Poly6 is seeking a Senior Manufacturing Engineer to lead the development, industrialization, and scale-up of front-end manufacturing processes - including printing, die cleaning, drying, post-cure, and injection.

This role owns the earliest and most sensitive steps of production, establishing the material, dimensional, and process stability that drives downstream yield.

Because front-end manufacturing is the bridge between R&D and high-volume production, this position carries a strong emphasis on process development, experimentation, and early-stage industrialization.

The engineer will work closely with R&D, production, quality, tooling, and automation teams to translate new technologies into reliable, scalable operations.

Key Responsibilities:

Process Ownership & Technical Leadership


* Own daily engineering support for printing, die cleaning, drying/post-cure, and injection operations.


* Establish and maintain process windows, control limits, and defect-prevention standards.


* Lead troubleshooting for upstream issues (print anomalies, fill issues, drying/cure variation, die-cleaning defects).

Process Development & Industrialization


* Translate R&D formulations and settings into stable production processes.


* Lead DOEs for print parameters, cure profiles, injection settings, and drying cycles.


* Validate new materials, tooling, and equipment for readiness and repeatability.

Throughput, Capacity & Material Flow Optimization


* Improve utilization of printers, dryers, post-cure ovens, and injection presses.


* Develop takt-based flow, staffing models, and equipment loading plans.


* Reduce early-stage variation to protect downstream yield.

Equipment & Technology Integration


* Support specification, installation, and qualification of new printers, injection presses, ovens, and cleaning tools.


* Partner with maintenance and controls teams to improve reliability and safety.

Data-Driven Problem Solving


* Build data pipelines for print parameters, injection profiles, and cure...
