The Anticipated closing date of this job posting is October 28, 2026.

Actual compensation within the range will be determined based on experience, skills, and qualifications considerations.

JOB SUMMARY (the purpose and general nature of the job):

The Research and Development Mechanical Engineer III will possess advanced knowledge of engineering principles and will execute product development activities as directed by immediate and upper-level management with little or no guidance. This role is responsible for driving designs from concept through commercialization, ensuring designs meet performance, cost, manufacturability, quality, safety, and compliance requirements. The Research and Development Mechanical Engineer III supports the global Stolle community by providing technical expertise, data-driven recommendations, and effective communication to management, manufacturing, assembly, field service, vendors, and customers to enable smooth product transitions.

This position assumes ownership of assigned projects, including providing project direction and making decisions required for project success.

PRINCIPLE ACCOUNTABILITIES include the following:

• Provides high-level engineering support as required to the global Stolle community while drawing from a wide breadth of engineering knowledge.
• Maintains involvement with assigned projects from design inception through commercialization; supports technical execution through design, build, test, trial, and implementation phases.
• Assumes ownership of assigned projects and is responsible for project success (technical performance, schedule, cost, manufacturability, and quality); drives issues to closure and escalates risks early with clear options and recommendations.
• Provides project direction within scope by making timely, well-supported technical decisions; aligns stakeholders, establishes priorities, and drives project outcomes through accurate estimating and design-to-cost decisions while monitoring material spend.
• Provides sales and marketing support on new ideas and cutting-edge, industry-changing technology; contributes to value proposition development and customer-facing technical discussions.
• Accurately estimates material cost and engineering labor on design projects; supports profitability/ROI analysis and design-for-cost decisions.
• Develops, documents, and communicates requirements; proactively revalidates requirements and performs what-if/contingency planning to mitigate design/test/trial risk.
• Offers creative, unique, and effective design solutions when presented with complex engineering problems; executes problem solving and root cause analysis.
• Creates and releases complete drawing packages and models using CAD/PDM; including configurations, product structure, and bill of materials creation/management in CAD/ERP.
• Designs components and systems across varied manufacturing processes, including sheet metal, mill/lathe parts, weldments, cast parts, assemblies, mechanisms, and tooling as applicable.
• Performs and/or coordinates analysis activities such as hand calculations/rough evaluation, power/utility/torque calculations, gearing and mechanism (dynamics) analysis, fatigue/life calculations, statistical analysis, and finite element/structural analysis as appropriate and with actionable outcomes.
• Develops test plans, acceptance criteria, and test rigs/fixtures as needed; executes functional and longevity testing; analyzes and documents results to support sound engineering conclusions.
• Supports dimensional/alignment/measurement and inspection activities (as needed) to validate designs and troubleshoot issues.
• Supports offsite tests, trials, and field activities as required; including field trial planning/monitoring, site installation coordination, and customer support (domestic and international travel as needed).
• Communicates and supports purchasing, planning, manufacturing, quality inspection, assembly, field service, vendors, and OEM engineering regarding part design, machine assembly, and component/product optimization requests.
• Engages with vendors regarding process selection, tolerances, lead times, and cost; identifies/evaluates vendors; supports part quoting, vendor identification, and procurement…
