• Influence gains and error dynamics to meet performance targets under varying load and speed conditions.
• Translate physical behavior of the supplier mechanism into robust, real-time software control functions.

• Integrate system software functions with firmware, hardware drivers, and the purchased print mechanism.
• Develop and execute system-level validation plans covering thermal performance, NIP force consistency, media transport stability, and mode-specific print quality.
• Perform data-driven calibration and correlation between simulation models and actual hardware behavior.
• Support Software-in-the-Loop (SIL) and related verification approaches.

• Provide technical leadership by training and assisting team members on system function development, control strategies, and calibration methods.
• Review system and software requirements for completeness, correctness, and testability.
• Actively participate in design reviews, architecture reviews, and other quality gates to control quality and prevent defects.
• Lead or contribute to FMEA (Failure Mode and Effects Analysis) activities related to system functions and control strategies.
• Drive defect analysis, root-cause investigation, and corrective actions at the system function level.
• Ensure traceability from requirements through design, calibration, and validation.

• Work closely with software, firmware, hardware, and mechanical teams.
• Interface with the Print mechanism supplier to understand mechanism characteristics and translate them into software system requirements and calibration strategies.
• Document system functions, interfaces, calibration procedures, models, and validation results clearly and thoroughly.

• Strong background in Software System Engineering for electromechanical or mechatronic products.
• Proven experience developing and calibrating system-level software control functions.
• Excellent practical knowledge of PID control and the ability to tune gains for fast, accurate performance.
• Proficiency in MATLAB/Simulink for modeling, simulation, control design, and calibration.
• Solid understanding of real-time software constraints and embedded control concepts.

• Good understanding of thermal print mechanisms (or similar precision electromechanical systems), including:
• Thermal behavior and heat management
• Force/pressure control (NIP force)
• High-speed media transport dynamics
• Motor torque-speed characteristics under varying loads
• Ability to work effectively with a purchased mechanism and supplier technical data (design of the mechanism itself is not required).

• Experience reviewing requirements and participating in formal design/architecture reviews.
• Ability to train and mentor engineers on system functions, control strategies, and calibration.
• Hands-on experience with FMEA and structured quality/defect prevention methods.
• Strong analytical and problem-solving skills focused on system-level behavior.

• Scripting ability (Python, MATLAB, or similar) for calibration tools and data analysis.
• Comfortable working with sensor feedback (temperature, force, position, speed) inside software control loops.
• Clear technical documentation and communication skills.
• Bachelor’s or Master’s degree in Software Engineering, Systems Engineering, Control Engineering, Electrical Engineering, Mechatronics, or a related field.
• Relevant industry experience in product development involving precision electromechanical systems (printers, similar high-speed mechatronic devices, or comparable domains).

• Prior experience with thermal printers or high-speed media handling systems.
• Experience with Software-in-the-Loop (SIL) or Hardware-in-the-Loop (HIL) environments.
• Familiarity with functional safety or structured development processes (e.g., ASPICE, ISO 26262 concepts, or equivalent).
• Exposure to working with international suppliers (especially Japanese suppliers).
