Are you ready to solve problems most engineers will never see?

Do you thrive in hands-on environments where data, testing, and real-world performance drive decisions?

Are you looking for an engineering role where no two projects and no two industries are the same?

About Stress Engineering Services
Stress Engineering Services (SES) is an elite, one-of-a-kind engineering consulting firm, recognized for tackling some of the most complex and technically demanding challenges across industries. For more than 50 years, we have partnered with clients in energy, consumer products, aerospace, medical, and beyond, delivering trusted expertise in failure analysis, reliability, materials, and performanc

At SES, we stand apart through the depth of our technical knowledge paired with practical engineering judgment. Our teams don’t just develop theories, we deliver solutions that perform in the real world, helping clients mitigate risk, improve reliability, and confidently move forward.

Our Core Values

• We Over Me – We put the mission, our clients, and our team ahead of individual agendas
• 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

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

As a Packaging Engineer at SES, you won’t be confined to a single product or brand—you’ll work across a wide range of industries, materials, and packaging systems, solving real-world challenges through hands-on testing, analysis, and engineering insight.

This role blends engineering fundamentals with practical execution. You’ll evaluate packaging performance, troubleshoot issues, optimize designs, and provide clear, data-driven recommendations that directly impact product reliability, manufacturability, and cost.

From concept development through production, you’ll play a key role in delivering high-quality engineering solutions in a collaborative, small-team environment where your work is visible and impactful.

In addition, this role may involve applying advanced modeling, simulation, and optimization techniques to complex systems, supporting more data-driven and predictive engineering decisions.

What Makes This Role Different
Most packaging roles focus on a single product line.

At SES, you’ll:

• Work across multiple industries and packaging applications
• Solve unique, technically challenging problems that require creative, engineering-driven solutions
• Gain broad exposure that accelerates your technical development
• Operate in a consulting environment, where adaptability and problem-solving are essential

This is a role for engineers who want variety, ownership, and impact, not routine.

A Day in the Life
No two days look the same—and that’s the point.

You might start your day collaborating with engineers and clients to define project goals, refine designs, or develop testing strategies. As the day progresses, you could shift between analyzing performance data, troubleshooting a packaging failure, evaluating materials, or working directly with lab and manufacturing teams.

Some days are focused on deep technical analysis—reviewing data, running calculations, building models, or evaluating system performance. Others are more hands-on—executing tests, inspecting components, or identifying root causes in real-world conditions.

By the end of the day, your work translates into tangible results: problems solved, designs improved, and decisions backed by clear engineering insight.

Key Responsibilities

• Serve as a technical partner to client packaging teams, providing independent analysis and engineering support
• Plan, execute, and interpret packaging tests with both technical rigor and practical relevance
• Evaluate packaging performance across design, manufacturing, distribution, and use conditions
• Perform engineering analysis, including calculations, data interpretation, modeling, and optimization where applicable
• Apply systems-level thinking to solve complex, real-world packaging and performance challenges
• Interface directly with clients to communicate findings and recommendations
• Coordinate with vendors and suppliers to gather technical data and support decision-making
• Manage project timelines and deliverables across multiple stakeholders

Basic Qualifications

• Bachelor’s degree in Packaging, Mechanical, or Plastics Engineering
• 5+ years of experience in consumer product packaging
• Experience supporting packaging from concept through production launch
• Strong foundation in engineering fundamentals (mechanics, materials, data analysis)
• Knowledge of packaging materials (polymers, corrugate) and testing methodologies
• Experience with manufacturing processes (injection molding, blow molding, thermoforming)
• Experience troubleshooting and driving continuous improvement initiatives
• Proficiency with CAD software
• Experience with modeling, simulation, or optimization of complex systems
• Strong written and verbal communication skills
• Ability to manage multiple priorities in both independent and team environments

Preferred Qualifications

• Master’s or Ph.D. in Packaging, Mechanical, Plastics Engineering, or a related technical field
• Deep experience in multi-agent planning, system optimization, or operations research methodologies
• Experience formulating and solving mixed-integer or other constrained optimization problems
• Experience using simulation tools such as SimPy or similar discrete-event modeling platforms
• Advanced programming experience in Python for modeling, data analysis, or automation
• Background in Mathematics, Economics, Physics, Electrical Engineering, or Controls Engineering
• Experience with predictive modeling or simulation tools in engineering applications
• Exposure to labeling, filling, or warehouse operations
• Experience working with a wide range of materials (HDPE, PET, PP, ABS, etc.)
• Consulting or client-facing engineering experience
• Demonstrated project leadership experience (PMP a plus)
• Experience in regulated or complex product environments
• Experienced, tenured engineer with the ability to make an immediate impact in a fast-paced consulting environment
