Job description

Invinity Energy Systems plc (AIM: IES) is a world-leading manufacturer of vanadium flow batteries for energy storage. Built in our factories in the UK and Canada, the Company’s proven, commercialised, longer duration energy storage technology has been deployed at scale and dispatched gigawatt-hours of electricity for customers across the world.

Invinity’s safe, scalable and durable battery technology is a trusted and safer alternative to lithium-ion batteries. Endurium VFBs are engineered for heavy‑duty, high‑throughput applications, they don’t wear out, cannot catch fire and are designed to be operated for 30 years or more. Our products address the challenges of our global energy system, unlocking the power of renewable generation by delivering energy storage without limits.

The energy transition means, fundamentally, a push toward electrification using renewable energy. Renewable energy’s intermittent nature is tamed by energy storage, and not just any storage, but large‑scale, long‑duration and robust stationary energy storage. That’s where Invinity comes in. We make flow batteries that store energy in a liquid electrolyte containing vanadium. Invinity’s vanadium flow batteries are highly advanced versions of this proven technology.

Invinity is deploying large‑scale projects in the UK and internationally. We are looking for a Maintenance Planner based in Bathgate who will develop programs and plans to perform corrective and preventive maintenance, whether performed by team members, customers or contractors, to ensure continued performance and availability of deployed systems.

Reporting to the Director, Customer Operations and working closely alongside all members of the Customer Operations team, you will scope and schedule the on‑site work by incorporating maintenance plans, customer feedback, issues reports, and system operational data, and will ensure appropriate logistic elements are in place to support the planned work. You are someone who understands field maintenance and what it takes to deliver this effectively. Safety and effectiveness are top of mind. You always act with integrity and engage positively with customers, colleagues and contractors. You will own the maintenance planning for systems deployed around the world and will contribute to the operational goal of increasing availability and customer satisfaction, and lowering maintenance costs.

Job Description

• Prepare maintenance plans and schedules that integrate customer and Invinity maintenance and operations goals
• Coordinate plans and schedules with project managers, other departments, and customers to reduce costs, downtime and inconvenience to customers
• Raise work orders and ensure appropriate resources (materials, tools, trained personnel, logistic support, etc.) are available to perform the work safely and efficiently.
• Liaise with the Logistics and Supply Chain teams to coordinate shipping, customs, and site delivery requirements, and liaise with customers on site activities, deliveries, work scope and timing.
• Develop site and service reports following site visits, and monthly site performance and status reports to meet customer reporting requirements.
• Manage the global spares pool and optimise sparing levels as appropriate, working closely with the logistics and supply chain teams to ensure timely availability of parts worldwide.
• Manage the RMA process and the disposition, repair, or replacement of returned materials
• Manage company tools and equipment, including calibration and new tool development or introduction of new tools where required
• Monitor asset performance, maintenance history, and failure trends using the maintenance management system (MMS) to inform preventative and predictive maintenance strategies
• Investigate issues in the MMS and ensure issues raised are managed through to completion, including coordination of corrective actions and follow-up activities
• Ensure maintenance records, work orders, and asset data are accurate, complete, and maintained within the MMS
• Support root cause analysis and continuous improvement initiatives aimed at improving system availability, reliability, and maintenance efficiency
• Create and maintain maintenance procedures, and develop budgets and quotes for maintenance activities (parts, materials, travel, contractors etc.)
• Ensure maintenance activities are planned and executed in accordance with company health, safety and quality requirements, including relevant Risk Assessments and Method Statements (RAMS) and local regulatory obligations
• Assist and support Customer Operations Management, contributing to operational planning, reporting, and continuous improvement initiatives.
