Leading global energy storage business at the forefront of lithium-ion battery manufacturing and system integration. Backed by a major international group, they are now launching a 2M sq. ft. production and warehouse facility in Phoenix, Arizona. This is a flagship site supporting the rapid growth of utility-scale energy storage across North America.

The business is scaling fast, processes are still being shaped, and HR plays a critical role in getting it right from day one. Strong focus on safety, operational excellence, and delivering fully integrated storage solutions into a market that’s only going one way.

The role:

This is a hands-on HR Generalist position with a strong recruitment focus, particularly in the early stages of site ramp-up.
You will be the main HR point of contact on-site, sitting at the heart of the operation supporting hiring, stabilising the workforce, and acting as the go-to HR partner during a critical growth phase.

• Partner with hiring managers to define roles and drive recruitment activity (high-volume + specialist)
• Manage candidate flow: screening, interviews, offers, and onboarding coordination
• Coordinate closely with agencies to secure talent quickly and efficiently
• Maintain accurate tracking and reporting across hiring activity
• Support onboarding and offboarding processes, including first-day coordination
• Act as a key point of contact for employee relations on site
• Support a shift-based workforce (attendance, overtime, day-to-day issues)
• Work closely with central HR on more complex cases and broader HR initiatives
• Contribute to building HR processes and structure as the site scales
• Support wider HR projects and initiatives as required

Essential requirements:

• 5+ years HR Generalist experience
• 3+ years recruiting experience (ideally high-volume)
• Experience in a manufacturing, warehouse, or industrial environment
• Bilingual Spanish and English (essential)
• Strong understanding of U.S. employment law
• Ability to manage multiple priorities in a fast-paced environment
• Comfortable being on-site and hands-on with the workforce
• Strong organisational skills and attention to detail

Desirable requirements:

• Experience with HRIS systems (ADP preferred)
• HR certification (PHR / SHRM-CP)
• Experience supporting site start-ups or scale-ups

Why this role is interesting:

This isn’t a traditional HR role.
You’re walking into a site that’s being built, a workforce that’s being shaped, and a business that needs a hands-on HR professional to take ownership on the ground.

If you’ve ever wanted to:

• Be part of a major battery manufacturing build-out in the US
• Take on a broad, autonomous HR role with real day-to-day impact
• Work closely with operations in a fast-moving, high-growth environment
