Job Location:
Shenzhen, China
About the role
This Senior Manufacturing Engineering Manager will lead the manufacturing engineering team in China and provide process standards and technical support to factories in Africa. This role will champion design-for-manufacturability, new product introduction (NPI), and operational excellence—building a scalable, cost-effective global manufacturing platform to enable the delivery of millions of off-grid energy products that empower underserved communities.
Process Development & NPI
- Lead the development and validation of new technologies, materials, processes, equipment, and products.
- Develop new product process routes and manufacturing platforms, and effectively enable domestic contract manufacturers and overseas factories.
- Participate in early-stage product development to assess equipment requirements, process flows, and parameters; drive R&D-manufacturing alignment through DFM to shorten the NPI cycle.
- Identify potential risks in new process development, establish a tiered risk control mechanism, and drive closed-loop solutions.
Mass Production
- Drive lean manufacturing initiatives to improve production efficiency, reduce costs, and mitigate quality risks.
- Increase automation levels to ensure high process consistency and reliability, achieving cost reduction and operational efficiency.
- Lead and implement continuous improvement projects to deliver measurable results.
- Collaborate effectively with Quality, R&D, and Project teams to resolve critical technical issues.
- Apply engineering methodologies (e.g., SPC, DOE, FMEA) to analyze production anomalies and develop sustainable corrective actions.
- Execute TRN/ECN/PCN change notifications in a timely and compliant manner.
System & Workflow
- Manage secondary development of the Manufacturing Execution System (MES), and leverage production data for analysis and decision-making.
- Develop standardized process documentation, including PFMEA, process flow charts, SOPs, and control plans.
- Ensure all team outputs follow industry-standard engineering practices and workflows.
Team Management
- Lead and manage a high-potential manufacturing engineering team, fostering a culture of technical excellence and results-driven execution. Define clear individual and team goals with measurable KPIs.
- Build a robust talent pipeline through internal development and strategic hiring to enhance overall team capability.
- Conduct regular technical review meetings to align on process development plans and drive task execution to completion.
-
A bachelor’s degree or higher in Electronics, Mechanical Engineering, Mechatronics, or a closely related field.
- 10+ years of manufacturing engineering experience in the electronic/electrical products industry, including at least 5 years specifically in energy storage product manufacturing.
- Deep expertise in PCBA manufacturing processes (SMT, DIP, testing, and rework).
- Solid understanding and practical application of Lean Manufacturing, Kaizen, Six Sigma, PFMEA, and DFX (Design for X) methodologies.
- Proven ability to collaborate cross-functionally—with R&D, Quality, Supply Chain, and contract manufacturers—to drive aligned outcomes.
- Strong communication and reporting skills, with the ability to clearly articulate technical issues and solutions.
- Full professional proficiency in English (listening, speaking, reading, and writing), capable of using English as a working language in global teams.
-
Professional growth in a dynamic, rapidly expanding, high-social-impact industry
- An open-minded, collaborative culture made up of enthusiastic colleagues who are driven by the challenge of innovation towards profound impact on people and the planet.
- A truly multicultural experience: you will have the chance to work with and learn from people from different geographies, nationalities, and backgrounds.
- Structured, tailored learning and development programs that help you become a better leader, manager, and professional through the Sun Center for Leadership.
Sun King is the world’s leading off-grid solar energy company, combining cutting-edge product design, fintech, and field operations to deliver energy access for the 1.8 billion people who live without an affordable and reliable electric-grid connection.
Sun King has built a new kind of energy utility: distributed, green, customer-centric, and affordable. We bring clean, reliable, decentralized energy directly into people’s lives — from solar kits that provide first-time energy access to multi-kilowatt systems that serve both off-grid users and grid-connected customers powering larger homes, schools, hospitals, farms, offices, and light manufacturing.
Already, 25 million homes and businesses rely on Sun King for electricity supply and the appliances and services it enables: lighting, televisions, fans, refrigeration, and smartphones.
Sun King combines energy generation, energy-efficient appliances, installation, and financing into one seamless offering. Think of it as a distributed utility, designed for wherever energy is needed and designed to scale with its users as incomes and energy needs grow.
Sun King makes solar products affordable to low-income households and businesses via ‘pay-as-you-go’ (PAYG) purchase financing. Sun King installs solar after customers pay a small deposit. Customers then make small, manageable payments of as little as US $0.14 a day via mobile money or cash.
Instead of paying for expensive, polluting, and health-damaging kerosene for lighting or diesel for power, customers unlock savings through accessing solar power and after one to two years of payments, customers own their solar equipment outright.
Sun King collects payments digitally through mobile money systems and its 35,000 field agents — over 1 million payments each day. To date, Sun King has extended more than $1.4 billion in PAYG loans to customers.
Sun King began by powering homes and businesses with solar systems delivered through PAYG financing. Now, we’re using the same model to make smartphones and clean cooking equipment affordable: helping households connect to the digital economy and transition from wood-based fuels to modern, sustainable alternatives.
Sun King employs 3,500 full-time staff in 14 countries, with specialties spanning product design, data science, logistics, customer service, sales, software, operations, and more — all with a passion to serve off-grid families. Sun King is committed to gender diversity in the workplace. Women represent 42% of Sun King’s workforce.
