JOB MISSION
HwIT is seeking a Packaging Product Development Engineer focused on optical commutations products. You will be a key technical contributor supporting the hardware lifecycle of our photonic modules — from assisting in mechanical/thermal simulations and 3D CAD design to the execution, validation, and optimization of cleanroom packaging processes.
Your main focus will be a hands-on environment bridging RD design with manufacturing reality: supporting multiphysics simulations, detailing micro-assemblies, executing DOEs (Design of Experiments) for method validation, and technically investigating root causes to ensure structural integrity and maximize yield in global scale production.
SCOPE RESPONSIBILITIES
1. Product Development and Validation
- Mechanical Optomechanical Design for Packaging: Develop 3D CAD models and detailed 2D manufacturing drawings for high-precision optoelectronic packages, test fixtures, and structural assemblies, applying GDT standards.
- Multiphysics Thermal Simulation: Conduct Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) to simulate thermal dissipation, mechanical stress, and structural integrity of photonic modules.
- Prototyping Design Validation: Support the rapid prototyping phase and work closely with the Reliability testing team to validate simulation models against empirical data from testing (e.g., Telcordia GR-468, MIL-STD).
2. Process Development and Validation
- Critical Parameter Optimization: Assist in defining and optimizing critical process parameters such as die attach (e.g., conductive epoxies, eutectic soldering), wire bonding, and optical alignment.
- Encapsulation Techniques: Develop hermetic and semi-hermetic encapsulation techniques for photonic modules.
- Material Qualification: Validate new materials, adhesives, and sealing processes according to high-reliability standards.
3. Yield Optimization and Troubleshooting
- Root Cause Investigation: Run investigative activities in cleanroom processes to detect the root cause of issues affecting the yield and assembly times of photonic components.
- Design of Experiments (DOE): Run DOEs to characterize processes, define critical variables, and find the best assembly recipes.
- SPC Alignment: Validate and approve operational methods and process parameters consistent with the Statistical Process Control (SPC) required by Product Engineering.
4. NPI Integration and Manufacturability
- Design for Manufacturing (DFM): Execute DFM and development activities in packaging components under senior guidance, promoting technical alignment between suppliers and developers, and evaluating the technical feasibility of new components.
- Team Training: Documentation and training the operational team in the meticulous execution of complex encapsulation recipes and methodologies;
- Process Transference: Collaborate side-by-side with Product Engineers and Senior Packaging Engineers to validate assemblies and transfer packaging assembly processes to high-volume manufacturing sites.
