Production Supervisor job at Soleil Power

Role Overview

The Production Supervisor is responsible for planning, executing, and continuously improving all manufacturing activities at Soleil Power’s battery production facility. This includes oversight of lithium-ion battery assembly lines (prismatic and cylindrical), workforce management, production scheduling, quality compliance, and operational efficiency.

The role is both strategic and hands-on, requiring direct involvement in daily production activities while helping to build systems, processes, and team capacity to support scale.

Key Responsibilities

Production Planning & Execution

• Develop and manage daily, weekly, and monthly production plans aligned with sales forecasts and inventory availability
• Ensure production targets (volume, yield, and timelines) are consistently achieved
• Coordinate raw material availability with procurement and logistics teams
• Optimize staff and machine utilization across multiple production streams (cylindrical and prismatic)
• Monitor and manage WIP (work-in-progress) and finished goods output

Team Leadership & Workforce Management

• Lead and supervise production technicians, engineers and operators along with support from the engineering team
• Train and upskill staff in battery assembly processes, safety procedures, and quality standards
• Establish clear performance metrics and accountability across the production team
• Foster a disciplined, safety-focused, and performance-driven culture

Process Development & Continuous Improvement

• Standardize production processes through SOPs and work instructions
• Identify and implement process improvements to increase throughput and reduce waste
• Lead commissioning, calibration, maintenance and optimization of production equipment
• Collaborate with Engineering/R&D on new product introduction and prototyping
• Drive lean manufacturing practices where appropriate

Quality Assurance & Compliance

• Ensure adherence to internal quality standards and testing protocols
• Work closely with quality assurance to reduce defects and improve yield
• Maintain production records to support traceability and certification requirements (ISO, UN, IEC)
• Ensure proper implementation of material inspections, in-process checks, final testing and OEM reporting
• Support audits and certification processes where necessary

Health, Safety & Environmental (HSE) Management

• Enforce strict adherence to safety protocols
• Ensure proper use of PPE and safe operation of all machinery
• Identify and mitigate production-related risks (thermal, electrical, mechanical)
• Work with the Environmental/OHS function to maintain compliance with IMS requirements
• Lead incident reporting and corrective action implementation on production-related incidents and non-conformities

Inventory & Resource Management

• Supervision of store and storekeeper
• Monitor usage of raw materials and components to minimize waste and losses
• Coordinate with warehouse and procurement on stock levels and reorder planning
• Ensure proper storage and handling of cells, modules, and finished batteries
• Track and manage tooling, consumables, and equipment utilization

Reporting & Performance Monitoring

• Track and report key production KPIs, including:
  • Output volume
  • Yield and rejection rates
  • Downtime and equipment utilization
  • Labor productivity
• Provide regular production reports to management
• Identify bottlenecks and propose corrective actions

Qualifications & Experience

• Bachelor’s degree in Engineering (Electrical, Mechanical, Industrial, or related field)
• 8+ years of experience in manufacturing or production environments
• Prior experience in battery manufacturing, electronics assembly, or similar industries
• Demonstrated experience managing production teams and scaling operations
• Experience working in early-stage manufacturing environments is an advantage

Technical Skills

• Strong understanding of production systems and workflow optimization
• Familiarity with lithium-ion battery systems, BMS integration, or electrical assembly
• Experience with production equipment such as welding systems, test equipment, and assembly lines
• Ability to interpret technical drawings, BOMs, and process documentation
• Proficiency in Excel, google sheets and basic production tracking tools

Core Competencies

• Execution-focused with strong operational discipline
• Problem-solving and root cause analysis capability
• Leadership and team management
• High attention to detail and quality standards
• Ability to operate effectively in a fast-changing, startup environment
• Strong communication and cross-functional coordination
• Comfortable working with limited supervision

Working Conditions
