Mechanical Design Engineer Mechatronics

About the Job

• At Southco we are looking for a Mechatronics Design Engineer having 5-7 years of experience with a strong background in design of sheet metal and plastic parts and assemblies integrated with electrical components: motors (DC/servo/stepper), Sensors, actuators, relays, connectors, switches and power supplies.
• You will be responsible for designing mechanical structures and assemblies while also understanding, selecting, and integrating electrical components like motors, sensors, actuators & wiring/harnesses to deliver complete, functioning systems. This role suits someone who thinks in both CAD models and electrical function selection /design.
• The successful candidate will take ownership of the complete end-to-end product development cycle, from concept generation through production release, while driving the design and validation of complex electromechanical systems.

Key Responsibilities

• Design, model, and analyze mechanisms integrated with motors (DC/servo/stepper), Sensors, actuators, relays, connectors, switches, batteries, and power supplies.
• Integrate electrical components into mechanical assemblies.
• Size and select motor drivers, power electronics, and wiring/harness routing within mechanical assemblies
• Ensure electrical component compatibility with mechanical enclosures (fit, connector access, cable management, grounding)
• Develop 3D CAD models, assemblies, and detailed 2D drawings using GD&T for manufacturing and procurement using UG NX.
• Conduct tolerance stack-up analysis for linkage assemblies to ensure functional performance across manufacturing variation.
• Lead fundamental requirement mapping, regulatory compliance screening, strategic material selection, rigorous design effort estimations and Mechanical BOM preparation.
• Moderate DFM/DFA and work closely with suppliers/vendors for tooling and production readiness.
• Spearhead Design Failure Mode and Effects Analysis (DFMEA).
• Actively troubleshoot mechanical interface discrepancies, trailing fitment issues, and roll-out verified engineering changes.
• Design validation support and root cause analysis.
• Active participation in PPAP SOP support activities.
• Collaborate with cross-functional teams, Customers and Suppliers.
• Coordinate the physical builds and bench testing of experimental prototypes to qualify target kinematics, longevity, and fatigue.
• Create and maintain design documentation, calculations, and simulation reports.

Required Qualifications, Experience and Skills

• Masters in Mechatronics / Mechanical / Electrical Engineering
• 5-7 years of relevant engineering experience of Design in Engineering Industry, with a strong focus on electromechanical components.
• Proficiency in CAD software UG NX for 3D modeling, assembly design and 2D preparation.
• Proven experience with motor selection/sizing, motion control basics, or servo tuning
• Exposure to Noise analysis, NVH analysis
• Experience integrating electrical components into mechanical assemblies (wiring, connectors, enclosures)
• Strong understanding of GD&T, tolerance analysis, and DFM/DFA principles.
• Should have knowledge of engineering materials.
• Exposure to end-to-end product development cycle, change management system, IATF 16949 and ISO: 9001.
• Exposure to FEA tools for structural validation and motion control.
• Familiarity with prototyping methods, testing protocols, and design validation processes.
• Strong problem-solving skills with the ability to debug complex mechanical motion issues.
• Excellent communication and cross-functional collaboration skills.
• Must be initiative-taking, team oriented, result driven, flexible, visionary, and able to succeed in a fast paced, multiple-project growth environment.
