at Molex Inc in Lisle, Illinois, United States
Job Description
Product Design Engineer II, Sensing Solutions
Location: Lisle, IL (preferred) or Rochester Hills, MI
Experience Level: Mid-level (4-7+ years)
Travel: 20-30%
Relocation/Sponsorship: Assistance available
Your Job
As a Product Design Engineer II, you'll own the mechanical and electromechanical design of sensor components and sub-assemblies from concept through high-volume production. This is hands-on: you'll build prototypes, debug failures, validate designs, not just CAD. You'll work closely with a Senior Design Engineer mentor who will teach you sensor architecture, high-volume launch strategy, and how to think like a technical leader. Within a goal of 18-24 months, you'll be ready to lead sub-assembly designs independently. This is a real growth role, not a title.
Our Team
You'll join a growing, entrepreneurial Sensor Products engineering team developing innovative sensing solutions for high-growth applications. Our culture is built on principles over rules. In practice: You own design decisions on your components, no design-by-committee. You have meaningful ownership from day one. When you identify a design risk, you drive the solution; your mentor and leadership unblock, not second-guess. You'll contribute ideas to our product roadmap and process improvements, and we listen. You think like a business owner, cost, schedule, quality, and manufacturability all matter to you. You'll have a dedicated technical mentor, meaningful ownership, and a clear pathway to grow into senior and staff-level engineering roles as you develop your expertise.
What You Will Do
Own the mechanical design of parts and sub-assemblies from concept through production release
Create and maintain 3D CAD models and 2D drawings with appropriate GD&T and documentation
Build, evaluate, and iterate on prototypes; plan and execute validation testing (DVP&R)
Contribute to design trade-off studies and material selection
Apply DFM, DFA, DFR, and DFT principles in your daily design work
Perform tolerance stack-up analysis and contribute to structural, thermal, and failure analyses
Support engineering builds (EV, DV, PV) and production ramp activities
Interface with internal manufacturing partners and external suppliers to resolve design and process issues
Identify design risks early and drive data-driven corrective actions
Document and clearly communicate design intent, technical risks, and status to cross-functional teams
Participate in DFMEAs, design reviews, and technical problem-solving sessions with your mentor and team
Learn sensor physics, high-volume manufacturing, and how to think like a technical leader from your mentor
Who You Are (Basic Qualifications)
Bachelor's degree in Mechanical Engineering, Product Design Engineering, or related field
4 to 7 + years of product design or mechanical engineering experience, preferably with electromechanical assemblies
Hands-on experience in prototyping, testing, debugging, and supporting production builds
Experience developing and releasing 3D CAD models and 2D drawings with GD&T
Proficiency in CAD tools (NX, Creo, SolidWorks, or equivalent)
Strong understanding of mechanical fundamentals (statics, dynamics, strength of materials, thermals)
Proficient with tolerance stack-up analysis
Knowledge of common manufacturing processes: injection molding, machining, stamping, die casting
Experience with design validation processes (DFMEA, DVP&R) and failure analysis
What Will Put You Ahead
Experience with sensor development or sensor-based products (current, position, accelerometer, pressure)
Familiarity with sensor physics (magnetic, acceleration, pressure) and basic signal processing or calibration concepts
Experience in automotive or industrial environments with knowledge of standards like ASIL, EMC/EMI, IATF 16949
Experience designing components for high-voltage / high-current applications
Prior supplier management or manufacturing floor support experience
Experience with structural and thermal assessments and test data analysis
Demonstrated ability to mentor or help junior engineers grow
Who You Are
Ownership mentality - You don't wait to be told what to do. You see a design problem, propose a solution, iterate, and own the outcome
Learn from failure - When a prototype breaks, you dig in for root cause analysis, not just documentation. You're genuinely curious about why things work and why they fail
Bridge disciplines - You speak manufacturing engineer, supplier, test, and reliability engineer fluently. You can translate between them and drive consensus
Think like a business owner - You understand cost drivers, manufacturability constraints, and schedule impact. You balance perfection with pragmatism
Mentor mindset - You're eager to learn from your senior mentor and, as you grow, you'll help junior engineers level up. You're not territorial about knowledge
