• 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

• Based full-time at the Kirolo production facility
• Hands-on role requiring active presence on the production floor
• May require extended hours during peak production or commissioning phases

Compensation

• Competitive salary aligned with experience and local market benchmarks
• Paid time off
• Health insurance
• Work permit and other benefits if international hire
