OTTO Engineering•Carpentersville, IL

49d•Onsite

About The Position

This role involves developing and supporting ruggedized communication products, including speaker microphones, PTT devices, tactical headsets, and electromechanical assemblies, for mission-critical environments. The position requires strong mechanical design skills, hands-on prototyping, and collaboration across engineering, manufacturing, quality, and supply chain teams. The Mechanical Engineer II will work independently on assigned components or subassemblies with guidance from senior engineers as needed.

Requirements

Bachelor’s degree in Mechanical Engineering or related field.
Minimum 2 years of mechanical engineering experience in product development.
Proficiency with PTC CREO or similar parametric CAD tools.
Strong understanding of plastics, elastomers, die-cast metals, overmolding, and mechanical integration with PCBs.
Experience with DFM/DFA, tolerance analysis, and mechanical verification testing.
Ability to work independently in a fast-paced, hands-on engineering environment with strong follow-through and communication skills.

Responsibilities

Develop mechanical design concepts and performance specifications that meet customer, marketing, and environmental requirements (IP, MIL-STD, drop, vibration, thermal).
Perform engineering analyses including tolerance stack-ups, stress modeling, material selection, and statistical evaluation of test data.
Create 3D CAD models and detailed drawings of components and subassemblies using CREO.
Prototype, test, and iterate mechanical designs; support mechanical and environmental verification testing and document results.
Prepare engineering documentation, including drawings, BOMs, ECNs, specifications, and cost estimates for tooling and mechanical components.
Collaborate with manufacturing, quality, supply chain, and suppliers to ensure DFM/DFA, cost-effectiveness, and production readiness.
Support production and quality teams in resolving design or process issues on existing products; participate in MRB activities and discrepant material reviews.
Coordinate project activities across internal teams and vendors; communicate risks and recommend corrective actions.
Assist with other related duties as required or assigned.
