Technology

In short

Take the leap and redefine the future of shoe production with us. This is not a typical engineering role. You will be a hands-on pioneer, responsible for taming a groundbreaking, immature technology and forging the path from a single prototype to a reliable, global manufacturing reality.

Location: Busan, South Korea

Your Mission

Your mission is to be the critical bridge between an innovative prototype and an efficient, full-scale manufacturing operation. On is at the beginning of a critical and exciting journey, and this role is fully embedded in day-to-day operations to make our Lightspray innovation manufacturable, reliable, and scalable. You will spend significant time on the factory floor (Gemba), working with a high degree of autonomy to systematically solve problems, challenge conventions, and build a robust, repeatable manufacturing system that will change the industry.

Your Key Responsibilities:

Process Industrialization & Stabilization: Take full ownership of stabilizing the Lightspray manufacturing process. Apply Lean methodologies to analyze the current state, identify opportunities, and lead the implementation of a future state with improved flow and reduced waste.
Prototype to Production Transition: Actively participate in sampling and small-batch production runs. Use these opportunities to gain deep, hands-on knowledge of the process, identify potential failure modes early, and inform the strategy for full-scale production.
Equipment & Tooling Qualification: Lead the end-to-end qualification process for new equipment and tooling (IQ/OQ/PQ), defining acceptance criteria and ensuring assets are ready for high-volume production.
Process Capability & Control: Establish and monitor Statistical Process Control (SPC) to ensure process stability. Conduct process capability studies (Cpk/Ppk) to prove the process can consistently meet quality specifications.
Stakeholder Alignment & Communication: Act as a central communication hub for the Lightspray process. You will constantly interact with and align a wide range of stakeholders, including the shop-floor manufacturing team, central Innovation teams (Plastics, Robotics, Mechanical), external machine suppliers, and other global engineering teams.
Digital-to-Physical Integration: Act as the link between the digital design and the physical workflow. Troubleshoot and refine robotic programs, validate and optimize process parameters, and ensure tooling and automation perform reliably on the factory floor.
Process Risk Management: Proactively identify and mitigate manufacturing risks by leading Process Failure Mode and Effects Analyses (PFMEA) with cross-functional teams.
Knowledge Capture & Standardization: Develop, write, and implement clear, effective standardized work documentation, including control plans, SOPs, and OPLs, to reduce process variability and empower the manufacturing team.
Manufacturing Blueprint Contribution: Play a key role in creating and refining the comprehensive manufacturing blueprint, the master document that will enable the successful and standardized scaling of Lightspray technology across global production sites.
Design for Manufacturability (DFM): Provide constant, data-driven DFM feedback to the Innovation teams to ensure future designs are optimized for stable, high-volume production.
Performance & Culture Impact: Directly influence factory performance by improving Overall Equipment Effectiveness (OEE). Your success will have a tangible impact on the confidence, morale, and continuous improvement culture of the entire manufacturing team.
Global Support: Be available for international travel to support technology transfer, process scaling, and troubleshooting at other On facilities.

Your story

A Bachelor's or Master's degree in Mechanical, Industrial, Mechatronics, or a related engineering field.
3-7 years of experience in a manufacturing environment with a strong focus on new process introduction (NPI), automation, or process scaling.
An entrepreneurial mindset with a strong sense of ownership and a proven ability to manage complex projects and make sound, independent decisions in a dynamic environment.
A passion for innovation and a hands-on mentality, with direct experience in the full industrialization lifecycle, including equipment qualification (IQ/OQ/PQ), process validation (Cpk/Ppk), and creating robust control plans.
You have a demonstrated history of applying Lean Manufacturing tools (e.g., Value Stream Mapping, 5S, Kaizen, Standard Work, Poka-Yoke, A3 Thinking) to achieve measurable improvements.
Excellent communication and influencing skills, with comfort adapting your style to effectively align stakeholders from the factory floor to R&D labs and external vendors.
You are comfortable and effective working directly with complex electromechanical systems (robotics, automation, polymer processing).
You possess a strong computational aptitude and can troubleshoot logic-based systems (e.g., robot programs, PLC logic) to diagnose issues in an automated workflow.
A tenacious and structured problem-solver who thrives on tackling ambiguous challenges. Familiarity with risk assessment tools like PFMEA is a strong plus.
Lean Six Sigma Green Belt or Black Belt certification is a plus.
