Responsibilities:

The TSMS Packaging Principal Engineer is a technical position that provides technical oversight and leadership for packaging materials, equipment, and operations at the Lilly Kenosha County (LKC) site. As LKC is a greenfield site, this role will be foundational in standing up the packaging technical program, from equipment and packaging line design input, through tech transfer and process validation (PV), to sustaining commercial support. Upon the start of commercial production, the role's objectives shift to maintaining the validated state of applicable processes, monitoring metrics to ensure a state of control and capability, harmonizing control strategies across process teams, driving continuous improvement, and serving as an escalation point for day-to-day packaging operations issues.

Primary objectives include the start-up and compliant manufacturing of LKC products, including implementation of the packaging process control and validation strategy. The Packaging Engineer is responsible for providing technical support for the processes, materials, systems, and equipment associated with packaging. The scope of the role includes packaging for products transferred to and/or launched at the LKC site.

While this role is not expected to be the technical expert on all products and platforms, it is expected to be the site expert in the regulatory, internal, and other requirements governing packaging. A key part of this role is ensuring consistency in approach and process across the product lifecycle, from tech transfer through regulatory submission and into routine manufacturing, and in aligning LKC's technical approach with sister DAP sites as the network matures. The role also develops and implements a technical agenda and serves as a mentor within the TSMS team, engaging in upstream and external-to-site activities related to packaging.

Key Objectives/Deliverables:

Understand the scientific principles required for packaging combination drug products, including the interaction of chemistry, equipment, aseptic processes, and container closure systems.

Serve as a technical SME during the design, build, and commissioning phases at a greenfield site, providing manufacturing science input into packaging line, equipment, and material design to support future tech transfer and validation.

Own the technical agenda for the LKC Packaging TSMS program.

Provide technical oversight for packaging materials, including serving as site lead for printed packaging materials and serialization as the program matures.

Provide packaging technical support to operations with respect to materials, equipment, and processes.

Lead technical evaluations and problem resolution, including troubleshooting and root cause analysis.

Lead risk assessments of packaging operations and packaging material suppliers.

Provide technical support for all start-up activities (e.g., tech transfer, equipment/process qualification, process validation) ahead of and through PV.

Provide technical support for non-routine investigations (e.g., deviations, complaints), including consultation on quality and stability.

Prepare, review, approve, and provide technical support for relevant technical documents, such as: change controls, regulatory submissions, deviation investigations, validation protocols and summary reports, processing records, procedures, PFDs, PFMEAs, VMPs, APRs, Process Monitoring, and specifications.

Ensure an accurate instruction set (tickets & procedures) describes the process as performed and the control strategy for discrete manufacturing steps.

Lead risk management activities pertaining to assigned products and processes.

Develop, monitor, and appropriately react to statistically based metrics in real time to assess process variability and capability.

Identify opportunities and lead TSMS technical projects to ensure a successful site start-up and improve process control, yield, product quality, and/or productivity; implement process changes and improvements through the technical agenda.

Serve as a technical interface with upstream suppliers, equipment vendors, and the global packaging network, including sister-site DAP teams, to drive technical consistency across the network.

Serve as a technical mentor for TSMS engineers, scientists, and other disciplines.

Represent the LKC TSMS team for internal and external communications, including with suppliers.

Provide audit and regulatory inspection (including PAI) support, as needed.

Work within and lead cross-functional teams in a positive manner to implement TSMS objectives and deliver on business plan and quality objectives.

Ensure a safe working environment through compliance with safety rules and by actively participating in safety-related activities, helping to establish a strong safety culture from site start-up.

Basic Qualifications:

Bachelor's degree or higher in engineering, science, or a related field.

Engineering experience in plant, process, project delivery, maintenance, or related fields supporting packaging operations.

Minimum of 5 years of experience in a manufacturing organization (or other related experience).

Experience supporting cGMP manufacturing operations.

Strong interpersonal and teamwork skills.

Strong self-management and organizational skills, with the ability to operate with a high degree of autonomy in a start-up environment.

How we calculate "similar"

No black box, no LLM guesswork: a deterministic score built from four normalized attributes. Here's this role's own peer group at different match levels, so you can see the mechanism, not just the result.

Every comparison starts from the same 100-point budget: 25 for working in the same function, 40 for the same therapeutic area, 20 for the same or adjacent seniority, 15 for the same country. A dimension we can't confirm on both sides contributes nothing, never a guess, never a free pass.

Unmatched or unknown dimensions score exactly the same: 0 points, never a partial guess. A role we know almost nothing about beyond its function bottoms out at 25%; it never inflates to 100% just because there's little to compare against. Seniority uses a defined ladder (Associate → Manager → Associate Director → Senior → Principal → Director → Senior Director → Executive/VP) so "Director" and "Senior Director" count as adjacent, but "Director" and "Executive/VP" do not.
