Staff Engineer – Mechanical Systems

RIX Industries is seeking a highly experienced Staff Engineer to serve as a senior technical authority for the design, development, and long-term performance of complex mechanical components and systems.

In this role, you will operate as a principal individual contributor and technical advisor
, providing deep subject-matter expertise, mentorship, and engineering leadership across high-impact programs. You will apply advanced mechanical engineering principles to deliver innovative, reliable, and manufacturable solutions supporting mission-critical applications across Marine, Aerospace, Energy, Industrial, Medical, and Critical Infrastructure markets.

This position is ideal for a seasoned engineer who thrives in technically complex environments, influences design direction, and shapes engineering standards while collaborating across engineering, manufacturing, and customer-facing teams.

What You’ll Do

· Lead the design, analysis, and development of complex mechanical components and systems in alignment with technical requirements, regulatory standards, and business objectives

· Develop detailed specifications for new products, enhancements, modifications, and prototypes using advanced engineering judgment and analytical tools

· Select materials, manufacturing processes, and tolerances to ensure product performance, reliability, quality, and manufacturability

· Create and refine mechanical designs using CAD, modeling, and simulation tools

· Communicate complex technical concepts, design intent, and specifications clearly to engineers, managers, and non-technical stakeholders

· Engage directly with customers in technical discussions, including new product blueprinting interviews, translating requirements into executable specifications

· Plan and oversee prototype builds and validation testing to evaluate performance, safety, reliability, and compliance

· Analyze test data, field data, and performance results to identify improvement opportunities and drive design refinements

· Lead root cause analysis and troubleshooting efforts for complex failures or performance gaps; develop and implement corrective actions

· Serve as a technical advisor on high-risk or strategically important projects, influencing engineering decisions and design direction

· Develop analytical “digital twin” models to accelerate product development cycles

· Provide technical mentorship, guidance, and informal coaching to engineers and cross-functional teams

· Contribute to the development and continuous improvement of engineering standards, processes, and best practices

· Perform other duties in support of RIX’s engineering mission and long-term objectives
