We are a leading manufacturer of custom battery solutions, supporting mission-critical applications across aerospace, defence, medical, industrial, and emerging technology sectors worldwide.


As we enter the next phase of our growth journey, we are seeking an exceptional General Manager to lead our US operation. This is a rare opportunity for a commercially astute and operationally strong leader to take ownership of a growing business and play a pivotal role in its future success.

Leading a multi-functional team across manufacturing, engineering, supply chain, project delivery, and business support functions, you will be responsible for driving performance, strengthening organisational capability, and delivering sustainable growth.

Strong commercial and financial acumen, including P&L responsibility

Experience driving organisational change and performance improvement

Exceptional leadership capability with a proven ability to build and develop high-performing teams

Strong customer-facing and stakeholder management experience

The credibility, resilience, and presence to influence at all levels of an organisation

Experience within battery technology, aerospace, defence, electronics, medical devices, or other highly regulated, customer-driven industries would be advantageous.


Why Join Us?

This is an opportunity to lead a business with ambitious growth plans, innovative technologies, and a strong reputation within demanding and specialist markets.


For the right individual, this role offers the chance to make a lasting impact, shape the future direction of the business and build a high-performing organisation positioned for long-term success.
