• Unyielding Pursuit of Excellence – Excellence is the standard. We deliver the right solution, on time, every time
• Own It – We take accountability to earn trust and deliver results

This role is based in our Mason, Ohio office and requires onsite work five days a week.

As a Mechanical Packaging Engineer – Life Sciences at SES, you will primarily focus on solving complex challenges in medical device and life sciences packaging systems, supporting products used in real-world environments, from clinical settings to in‑home and self‑care applications.

In addition to regulated medical packaging, you will also contribute to industrial and consumer packaging projects, applying the same engineering rigor to improve packaging performance, durability, manufacturability, and cost efficiency across a broader range of products and distribution environments.

Rather than supporting a single product line, you’ll work across a diverse portfolio of regulated and industrial packaging systems, applying engineering fundamentals, hands‑on testing, and analytical rigor to ensure packaging meets performance, usability, and regulatory expectations.

This role blends mechanical engineering depth with applied packaging engineering. You will evaluate packaging performance, troubleshoot failures, optimize designs, and deliver clear, data‑driven recommendations that directly impact:

• Medical: product integrity, sterility assurance, and patient safety
• Industrial/consumer: durability, cost optimization, and supply chain performance

From concept development through validation and production, you will play a key role in delivering high‑quality engineering solutions in a collaborative consulting environment where your work is visible, impactful, and tied to real‑world outcomes.

You may also apply modeling, simulation, and optimization techniques to support predictive performance and risk reduction across both regulated and non‑regulated systems.

No two days look the same—and that’s intentional.

You may begin by collaborating with clients and internal teams to define test strategies or evaluate packaging designs for medical devices, ensuring compliance with strict regulatory and performance requirements. Later in the day, you could pivot to industrial or consumer packaging challenges, such as improving distribution durability, reducing material costs, or optimizing packaging for manufacturing efficiency.

• Analyze performance data or investigate a packaging failure in a sterile medical system or a high‑volume industrial product
• Evaluate materials ranging from medical‑grade films and sterile barriers to corrugate, plastics, and multi‑material systems
• Execute distribution, transit, and validation testing, supporting both regulated and non‑regulated applications
• Work directly in the lab building test setups, inspecting components, and simulating real‑world conditions
• Collaborate with suppliers and manufacturing teams to resolve design or production challenges

• Serve as a technical partner to clients, with a primary focus on medical device and life sciences packaging, while supporting industrial and consumer packaging applications as needed
• Plan, execute, and interpret packaging validation and performance testing (e.g., distribution, integrity, functional testing)…
