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.

Key Responsibilities

Support Field Teams Directly (Gemba Leadership)

• Serve as the primary People Partner for frontline and operational teams.
• Be physically present in the field to build trust, understand barriers, and support supervisors.
• Support new hire onboarding and engagement through consistent, high-touch field presence.
• Respond to and resolve teammate concerns, escalating issues thoughtfully and in alignment with Booster values.
• Partner with operations leaders to align workforce needs with business goals.
• Maintain compliance with all employment and labor laws at the state and federal levels.

Build Process & Drive Continuous Improvement

• Identify repetitive People issues and create standard work to address them.
  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.

Employee Relations & Compliance

• Manage teammate relations, investigations, and performance management coaching.
• Support corrective action, attendance tracking, and progressive discipline processes.
• Serve as a liaison between operations, safety, and HR to ensure adherence to policy and consistent documentation.
• Support the administration of leaves of absence, workers’ comp, and accommodations in partnership with the HR team.

Engagement & Retention

• Track morale and proactively identify engagement risks at the yard level.
• Partner with site leaders to implement recognition and communication rhythms that reinforce culture.
• Facilitate listening sessions and pulse checks to provide real-time feedback to leadership.
• Support and coach leaders in building high-performance, values-driven teams.

Strategic Partnership

• Participate in Lean Daily Management (LDM) and Tier meetings to share people's insights and remove barriers to success.
• Provide feedback loops from the field to shape Booster’s People strategy.
• Help translate organizational initiatives - like the Booster Business System, safety campaigns, and cultural programs - into practical frontline actions.
• Partner with HR leadership to prepare and deliver updates for Weekly and Monthly Business Reviews (WBR/MBR).

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.
• Grit, resilience, and curiosity - you thrive in imperfect systems and see challenges as opportunities to improve.
• A comfort level working in the field, after hours, and face-to-face with frontline teammates.
• Experience managing employee relations and compliance in California and/or Washington.
• Strong communication skills with the ability to translate HR policy into clear, actionable steps for frontline leaders.
• Working knowledge of HRIS systems, Excel/Sheets, and an analytical mindset for identifying patterns and improvement opportunities.
• Demonstrated success building trust, influencing leaders, and resolving issues at multiple levels of an organization.
• A mindset aligned with BBS principles - continuous improvement, standard work, and problem solving at the root cause.

Education & Certifications

• Bachelor’s degree in Human Resources, Business Administration, or related field (or equivalent experience).
• HR certification (PHR, SHRM-CP) a plus but not required.

Why Booster

• A company that builds systems around people, not people around systems.
• Hybrid, field-centric role with direct visibility into leadership and operational decision-making.
• Medical, dental, vision, life insurance, and equity participation.
• Unlimited PTO and flexible work options.
• Career pathways into leadership or HR business partnering aligned to BBS principles.

Success Looks Like

• Within 3–6 months: You’re embedded in your assigned region, known by name, and trusted as the go-to for People support.
• Within 6–12 months: You’ve eliminated recurring escalations by implementing process improvements and visual management tools.

Salary Range: $78,000 to $88,000 plus Booster equity
