Lead design, development, and optimization of assembly processes for drug delivery devices and combination products, spanning adhesive bonding, ultrasonic welding, laser welding, snap-fit assemblies, and mechanical joining methods. Establish and enforce Design for Assembly (DFA) and Design for Manufacturability (DFM) principles early in product development programs, influencing device design to ensure compatibility with automated assembly at production scale. Champion statistical rigor in experimental design (DOE), gauge repeatability and reproducibility (GR&R), and process capability studies (Cpk/Ppk) to build data-driven process understanding. Drive development of process flow documentation, assembly process specifications, and related technical deliverables to support program execution and regulatory submissions. Lead and standardize process development systems, tools, and best practices in partnership with DDCS and IDM subject matter experts. Technology Development and Innovation Identify, evaluate, and advance assembly process technologies to improve process robustness, capital efficiency, and time-to-volume across the DDCS portfolio. Profile and prioritize emerging assembly technologies-including advanced joining methods, vision-guided robotics, and AI-augmented process monitoring-against current and future DDCS program needs. Lead proof-of-concept and de-risking studies for novel assembly processes, part handling methods, and automation approaches in the Innovation Technology Center (ITC) and with external partners. Design and implement lab-scale equipment and fixtures to evaluate new assembly processes and part handling solutions; translate successful concepts into scalable manufacturing specifications. Develop business cases for the application of new technology to DDCS commercialization platforms, including cost-benefit analyses and risk assessments. Engage with external professional organizations, academic partners, and industry consortia to maintain awareness of leading and emerging assembly, automation, and process technology. Platform and Commercialization Support Provide focused technical support to platform teams and commercialization programs, ensuring assembly processes are robust, validated, and aligned with regulatory expectations. Perform Design for Manufacturability reviews; consult with and influence Device R&D to develop component designs compatible with automated assembly requirements and production scale. Lead or support generation of user requirements, process FMEAs, Comprehensive Hazard Analyses (CHA), and control strategies for assembly processes and equipment. Support OEM selection and provide technical oversight of outsourced process and equipment development, including review of equipment design documentation and factory acceptance testing. Maximize equipment fungibility-designing and specifying assembly solutions capable of supporting multiple device platforms and product generations. Support troubleshooting of assembly yield, throughput, and process variability issues across development and commercial manufacturing operations. Cross-Functional and External Engagement Build and leverage a strong technical network to advance assembly engineering capabilities across the organization and external ecosystem. Provide technical leadership and guidance to cross-functional project teams, serving as the assembly process engineering voice throughout product development and scale-up. Assess technical capabilities of OEMs and system integrators; ensure external solutions align with Lilly design controls, quality agreements, and engineering standards. Maintain productive relationships across DDCS, IDM, EDG, CTC, contract manufacturers, and global device network manufacturing sites. Serve as subject matter expert in technical studies, design reviews, regulatory interactions, and investigations as required to support project delivery. People Development and Knowledge Transfer Contribute to the growth of assembly engineering talent and institutional knowledge within DDCS. May manage a small number of direct reports; responsible for coaching, development planning, and performance management. Mentor engineers and interns with particular focus on process development fundamentals, statistical methods, and assembly engineering best practices. Support development of broader DDCS and device network technical capabilities through training, documentation, and knowledge sharing. Identify and help mitigate technical capability gaps within the ITC and ESPE team. Health, Safety, Environmental (HSE) and Quality Ensure compliance with safe execution of ITC activities, including Lilly policies such as Lock Out Tag Out (LOTO), Equipment Specific Instructions (ESI), and equipment design standards. Embed HSE considerations into equipment and process design, maintenance activities, and lab operations.
