Full Job Description

Senior Mechanical Design Engineer

Location: St. Louis, MO

Type: Full-Time

About Align Production Systems

At Align Production Systems, we engineer solutions that most companies can’t imagine — and then we build them. We specialize in custom-engineered material handling systems for demanding industrial applications, where no two projects are the same and every challenge is an opportunity to design something that’s never existed before.

We are an Engineer-to-Order organization at our core. Our engineers don’t sit behind a desk producing repetitive drawings — they lead complex projects from blank-page concept through fabrication, commissioning, and customer handoff. If you want to see your designs come to life on a real shop floor and in real facilities, Align is where that happens.

What You Bring

Bachelor’s degree in Mechanical Engineering, Manufacturing Engineering, or related field
6–8 years of hands-on engineering experience in an Engineer-to-Order or custom-build environment — this is a firm requirement, not a preference
Strong proficiency in SolidWorks or comparable CAD platform
Deep familiarity with manufacturing processes, mechanical assemblies, and heavy industrial equipment
Proven ability to lead projects independently and make sound engineering decisions with incomplete information

The Opportunity

We’re looking for a Senior Mechanical Design Engineer to bring deep technical expertise and project leadership to our St. Louis team. This isn’t a role for someone who wants to refine existing designs or follow templates. You’ll be the technical driver on custom heavy material handling systems — partnering directly with manufacturing, controls, and customers to deliver engineered solutions that work in the real world.

If you’ve spent your career in engineered-to-order environments and you’re energized by complexity and ambiguity, this role was written for you.

What You’ll Own

End-to-End Project Leadership

Lead engineering projects from initial concept through fabrication, testing, and field commissioning
Serve as the technical authority on complex, one-of-a-kind systems with competing constraints
Balance performance, cost, and schedule without sacrificing design integrity

Hands-On Engineering

Work directly alongside technicians and fabricators to ensure designs translate cleanly from drawing to build
Debug, iterate, and problem-solve in real time
Drive continuous improvement in design practices, build efficiency, and system performance

Cross-Functional & Customer Collaboration

Partner with manufacturing, controls, and sales teams to develop solutions that meet customer requirements and Align’s delivery standards
Engage directly with customers to clarify technical scope, manage expectations, and build confidence in our solutions
Work closely with suppliers to source and develop optimal components within design constraints

Technical Documentation & Mentorship

Maintain rigorous engineering documentation, drawings, and revision histories
Mentor junior engineers and contribute to building best practices across the engineering team

Who Thrives Here

Engineers who take ownership and drive projects forward without waiting to be told what to do next
People who find satisfaction in seeing a concept they created running on a production floor
Senior contributors who can mentor others while still doing the technical work themselves
Practical problem-solvers who know how to balance engineering ideals with real-world constraints
