Job description

We're building much more than powertrain and mobility solutions. We're building the people, culture, systems, and leadership capabilities that will support our next stage of growth.

Over the last 18 months, we have been building our HR function from the ground up. Rather than inheriting a mature HR organization with established processes, policies, and programs, we're creating them. That means there is a unique opportunity to influence how HR operates, improve employee experience, and help shape the future of the organization.

We're looking for an HR Generalist who is equally comfortable supporting day-to-day HR operations while helping us build better processes, stronger programs, and scalable people systems.

This role is ideal for someone who is:

✅ People-focused and genuinely enjoys helping employees and managers succeed

✅ Curious, proactive, and eager to learn

✅ Organized and detail-oriented

✅ Interested in how HR supports broader business goals

✅ Comfortable working in an environment where not everything is fully built yet

✅ Energized by the opportunity to improve and create rather than simply maintain

You'll work directly with the Head of HR & Safety and have exposure to recruiting, onboarding, payroll, training, employee relations, safety, communications, immigration support, talent programs, and special projects.

About Dumarey USA

Dumarey USA is an engineering and technology company specializing in advanced propulsion systems, powertrain development, testing, calibration, controls, and mobility solutions.

Our Plymouth, Michigan team supports a wide range of customer programs across automotive and transportation industries. We operate in a highly technical environment where engineers, technicians, and business professionals collaborate to solve challenging problems and support innovation.

We are a growing organization with ambitious goals and close connections to our global teams.

This includes:

• Payroll coordination and administration

This includes:

• Coaching managers on HR policies and practices
• Supporting performance management activities

• Employee experience
• Safety culture initiatives

What Success Looks Like

Success in this role is not simply completing tasks.

We are looking for someone who wants to understand the business problems behind the work, improve processes, anticipate needs, and help build an HR function that can scale with the company.

The ideal candidate is someone who asks:

• Why do we do it this way?
• Is there a better process?
• Can this be documented?
• Can this be automated?
• How does this improve the employee experience?
• How does this support the business?

We are not simply looking for someone to administer HR processes. We are looking for a business-minded HR professional who is curious, proactive, and capable of partnering with leaders to solve problems, improve employee experience, strengthen organizational capability, and help build the systems, processes, and programs that will support our next stage of growth.
