About Booster

At Booster, we’re on a mission to accelerate the transition to clean, efficient energy. We believe in fueling the planet’s movement - safely, sustainably, and with purpose.  Our values - Safety, Customer, Integrity, Excellence, Boldness, and Stewardship - guide how we operate and how we support our people.

The Booster Business System (BBS) is the engine behind our culture and performance.  It’s how we connect strategy, people, process, and measurement every day.  Through BBS, we develop systems that scale and empower teammates to solve problems, lead at the Gemba, and continuously improve.

About the Role

The HR Generalist plays a pivotal, hands-on role supporting Booster’s Operations and People teams. You’ll spend much of your time in the field - listening, problem-solving, and supporting frontline teams - while also identifying ways to make our systems smarter and more efficient.

This role starts as a doer: resolving teammate issues, supporting onboarding, and driving compliance.  Over time, success means reducing friction by designing repeatable processes and standard work - the essence of BBS.  You’ll help transition the HR function from reactive to proactive through structured problem-solving and daily management.

  Partner with HR leadership to document and optimize processes (onboarding, leave administration, corrective actions, etc.).
• Use BBS tools - such as 5 Whys and Pareto charts - to identify root causes and recommend improvements.
• Develop dashboards or trackers to increase visibility and accountability for HR metrics (turnover, engagement, onboarding success).
• Participate in process improvement and cross-functional problem-solving events focused on people systems.

What You Bring

• 3–5 years of HR or People Operations experience within high-growth, hands-on environments such as logistics, transportation, manufacturing, or field operations.
